THE PEOPLE, Plaintiff and Respondent, v. JOHN SAPP, Defendant and Appellant, 31 Cal. 4th 240

Opinion KENNARD, J. A jury convicted defendant John Sapp of the first degree murders of Robert Weber, Elizabeth Duarte, and John Abono. (Pen.

Code, § 187; further undesignated statutory references are to the Penal Code.) For each murder, the jury found that defendant personally used a firearm. (§ 12022.5.) With respect to the murders of Weber and Duarte, the jury further found to be true special circumstance allegations of multiple murder and murder for financial gain. (§ 190.2, subd. (a)(1), (3).) In addition, the jury found defendant to be a convicted felon in possession of a concealable firearm (§ 12021), and it found true an allegation that defendant had served a prior prison term (§ 667.5, subd. (b)).

At the penalty phase, the jury returned verdicts of death for the Weber and Duarte murders, and the trial court pronounced death sentences for those crimes. For being a convicted felon in possession of a concealable firearm, the court sentenced defendant to two years plus a one-year sentence enhancement. This appeal is automatic. (§ 1239.) We affirm the judgment in full. I. GUILT PHASE A. Prosecution’s Case On April 25, 1986, in Grass Valley, Nevada County, California, defendant was arrested on an outstanding warrant for being a felon in possession of a concealable firearm.

The next day, defendant confessed to three unsolved murders in California: the 1985 murder of Robert Weber in Colusa County, the 1981 murder of Elizabeth Duarte, and the 1975 murder of John Abono, both in Contra Costa County. 1. Murder of Robert Weber In August 1985, defendant’s friend Robert Weber lived in Concord. He was a “minor scale” cocaine dealer who was in debt to other drug dealers, including defendant. On August 13, Weber told his girlfriend, Linda Brown, that he and defendant were leaving for a few days to buy drugs.

Weber took with him $17,000, a sawed-off shotgun, and a nine-millimeter semiautomatic handgun. Around 7:00 o’clock that evening, Weber telephoned Brown and told her he was in the town of Clearlake with defendant but that the people they were planning to meet had not shown up. On August 17, 1985, defendant and an armed companion went to Weber’s condominium. While there, defendant answered a telephone call from Brown, who asked about Weber.

Defendant told her he had waited for Weber in a motel for three days but that Weber never showed up. (Actually, defendant and Weber had stayed at the El Grande motel in Clearlake the nights of August 13 and 14.) On August 18, two deer hunters found a man’s body, later identified as Weber’s, on a hillside on Walker Ridge in Colusa County, about 18 miles from Clearlake. Sheriff’s deputies summoned to the scene found bloodstains and four expended 9-millimeter casings a short distance from Weber’s body. Weber had died of multiple gunshot wounds to the head, back, chest, throat and both arms.

He had been dead at least 24 hours when the hunters discovered his body. While in custody some eight months later in Nevada County, after his arrest on the warrant for being a felon in possession of a concealable firearm, defendant discussed the Weber killing with Deputy Steven McCulloch of the Colusa County Sheriff’s Department. Defendant led McCulloch to the site at Walker Ridge where he had killed Weber. Defendant mentioned that Weber was walking in front of him on top of a hill, and when Weber turned around, defendant shot him several times with a 9-millimeter pistol.

Defendant then dragged Weber’s body some distance and rolled it over the side of the hill, noting that shrubbery stopped it from rolling farther down the hill. The area was the same location where, earlier in August 1985, hunters had discovered the body, and sheriff’s deputies had found bloodstains and expended 9-millimeter casings. Defendant denied that Weber had any money on him when killed.

According to defendant, “It was murder for hire.” Defendant said that some people, whom he refused to name, had paid him $10,000 in advance to kill Weber, and defendant then devised a bogus drug deal to lure Weber to the remote area outside Clearlake. In December 1986, while awaiting trial in this case, defendant wrote to Weber’s brother Michael: “Thought I’d write you one and only letter to let you know something that’s been eating away at me since your brother’s death. It’s obvious who pulled the trigger.

I’m curious if you ever think about who put the ‘thing’ in motion or who put up the ‘money’ to have it done. Those people are still out there just like you are. Your brother died being a good friend of mine. He owed me $32,000 but that’s not the reason he died. You’re probably relieved about my situation but you should still keep in mind the other ‘responsibles’ involved besides myself. I was used as a ‘tool’ and nothing else. . . .

I’m certainly not innocent of many things that I’ve been accused of but concerning your brother I was only a ‘tool’ used by the ‘other people.’ After I’m executed or if I am executed those ‘other people’ will still be out there. Sometimes I wish they would be executed right along side of me. They deserve it also in my opinion.” 2. Murder of Elizabeth Duarte In 1976, defendant worked at Chevron Research in Richmond, Contra Costa County, where he met coworker Elizabeth Duarte. The two dated for several years, but in July 1980, Duarte obtained a restraining order against defendant.

Around the same time, she began dating another coworker, James Luddon. Late in the evening of January 24, 1981, Duarte’s father came to her house in Richmond and picked up her five-year-old son. Duarte’s father brought the child back the next morning, but Duarte was not there. Later that day, the father notified the Richmond police that his daughter was missing. On January 26, Richmond police investigator Patricia McKittrick talked with defendant about Duarte’s disappearance.

When defendant asked if he was suspected of murder, McKittrick told him “no.” Defendant volunteered that Duarte made him “so mad” he wanted “to kill her.” According to defendant, on January 24 (when Duarte disappeared), he had gone fishing, and he did not return until the next day. At the end of the interview, defendant said: “If I am not a suspect, I ought to be; I had a dream the other night that [Duarte] got shot in the head.” Police obtained a warrant and searched defendant’s van on February 1, 1981. Caked dirt was on its clutch, gas and brake pedals, and dried human blood consistent with Duarte’s (type

A) was on the floor. After his arrest in Nevada County in April 1986, defendant discussed Duarte’s murder with Richmond Detective Michael Tye. Defendant said that he and Duarte had a “love-hate” relationship. He decided “to get rid of her because the love-hate was not balancing out anymore,” and only hate was left. Although defendant decided to kill Duarte for personal reasons (she had arranged for a hit man to shoot 20 rounds from a high-powered rifle at his house), he did not do so for some two months after making that decision.

In the meantime, someone offered him $20,000 to kill Duarte because she was a snitch. For $800, defendant had James Luddon, whom Duarte dated after breaking up with defendant, lure her to Luddon’s house. On the evening of January 24, 1981, when Duarte arrived at Luddon’s house, defendant was waiting in a bathroom. Defendant stepped into the hall and hit Duarte in the head so hard it split her scalp wide open, exposing skull bone. Defendant took Duarte in his van to his house, where he wrapped a bandage around her head and gave her a blanket.

The two then drove to the Lime Ridge area of Mount Diablo, where defendant had earlier dug a grave. They talked all night and defendant at one point handed Duarte his .38-caliber revolver, telling her to shoot him. Just as the sun was coming up, defendant shot Duarte once in the stomach. She told him to shoot her again, and he “emptied the gun into her.” Defendant added that he had buried Duarte wrapped in the blanket. On April 27, 1986, defendant led Detective Tye to the area of Duarte’s killing. There, police recovered human remains wrapped in a blanket and with a bandage wrapped around the skull.

Several .38-caliber bullets were found nearby. Dental records established that the remains were those of Elizabeth Duarte. She had been shot in the chest at least four times. 3. Murder of John Abono On December 22, 1975, 22-year-old John Abono was living in Concord, Contra Costa County. In the late afternoon, Abono and his friend Tim Bowler went to buy some marijuana from defendant, a longtime friend of Abono’s. Bowler had given Abono $200 to $300 to buy two pounds of marijuana. Abono drove by defendant’s house, and pointed it out to Bowler, who did not know defendant. Bowler noticed a Volkswagen parked in front.

Abono, who was driving, parked his sports car nearby. Bowler got out of the car and walked home, leaving Abono to buy the drugs. That evening, after waiting in vain for Abono and the marijuana, Bowler drove by defendant’s house several times. When Bowler drove by between 7:00 and 8:00 p.m. and again around 11:00 p.m., he noticed that the Volkswagen was gone but that Abono’s car was still parked on the street. Shortly after Abono’s disappearance, Concord Police Officer Richard Berendsen talked to defendant. Defendant said he knew he was suspected of killing Abono because Abono had once “snitched” on him.

Defendant claimed, however, that Abono had “simply left town” out of fear of defendant, and that Abono would eventually come back. After his April 1986 arrest for being a felon in possession of a concealable firearm, defendant spoke with Concord Police Officer Jim Webster about killing Abono some 10 years earlier. Defendant and Abono had been close friends for many years, but defendant became annoyed with Abono over “bad dope deals.” Defendant explained: “[Abono] put me in a situation of messing with heroin dealers. Just bad business. He was doing too many bad drug deals.

He was lying. . . . [and] a heroin addict.” So defendant decided to kill him and did so “within a few days.” Defendant gave these details of the murder: Defendant met Abono to transact a marijuana purchase. Abono appeared to be high on heroin. Defendant put a gun to Abono’s head and took him to an area near Castle Rock on Mount Diablo, Contra Costa County. He made Abono walk for about 45 minutes to; an isolated area. Defendant then shot him several times in the head. Initially, defendant covered Abono’s body with brush, but he later returned with a shovel and buried the body.

The area where defendant killed Abono was not too far from where he later killed and buried Elizabeth Duarte. Defendant directed police officers to the area of Abono’s killing, but they did not find Abono’s body. B. Defense Case To support a defense that defendant tends to falsely confess to crimes he did not commit and therefore that his confessions in this case could not be believed, defendant called Contra Costa County Deputy District Attorney Lawrence Barnes as a witness. Barnes testified that while defendant was awaiting trial in this case defendant admitted killing one Roger Gardner.

Counsel for the prosecution and the defense stipulated that Barnes was an “expert in judging the credibility of witnesses.” Barnes thereafter gave his opinion that defendant’s confession to killing Gardner was false, and that the actual killer was Larry Leroy Brownson, whom Barnes had prosecuted for the crime in 1986 and 1987. To show that he had killed Elizabeth Duarte for personal reasons—after she had a hit man shoot at him—defendant called Thomas Pompileo, who in 1980 had been his next-door neighbor. Pompileo described an incident in which Elizabeth Duarte visited defendant and left after a loud argument.

Shortly thereafter, a man standing on the freeway fired several shots from a high-powered rifle in the direction of defendant’s house. II. PENALTY PHASE A. Prosecution’s Case The prosecution presented evidence of defendant’s 1981 felony conviction for recklessly setting fire to an inhabited dwelling, and of five unadjudicated crimes.

These crimes were defendant’s possession in 1971 (at age 18) of a sawed-off shotgun; his possession in 1986, while in jail awaiting trial in this case, of a homemade knife or shank; the 1985 murder of defendant’s mother, Geraldine Sapp; and the attempted murders of A1 Redenius in 1983 and of Donna Smith in 1986. 1. Attempted murder of Al Redenius Shortly after 9:00 o’clock on the morning of November 9, 1983, Redenius was outside his house in Willits, Mendocino County, when he was shot in the face, neck, and hip from a shotgun fired from a car occupied by Brian Magidson, Herb Powell and a third man.

Earlier that morning, Dave Clement had seen defendant at Magidson’s house with Magidson and Powell. In April 1986, when defendant was arrested for being a felon in possession of a concealable firearm, he told the police that he was paid $10,000 to kill Redenius and that he had fired three shotgun blasts at Redenius, hitting him in the face. 2. Murder of Geraldine Sapp and attempted murder of Donna Smith We discuss these two unadjudicated crimes in the course of certain penalty phase issues. (See pts. VI.B.1. & C., post.) B.

Defense Case Through many witnesses, the defense presented evidence of defendant’s difficult childhood, including pathological behavior by his mother, Geraldine Sapp; his devotion and helpfulness to friends and relatives, particularly to his son Richard; and his extreme and chronic substance abuse dating from his early teens. Mental health professionals testified that defendant showed signs of orgánic brain damage and brain dysfunction. Defendant’s son Richard, who at the time of defendant’s trial was 20 and confined at the California Youth Authority for car theft, asked the jurors to spare his father’s life.

Raymond Procunier, the former Director of the California Department of Corrections, who for 40 years had worked in various penal systems, interviewed defendant and concluded that he would make a good “life” prisoner. Procunier said: “[Defendant] is willing to take his medicine, and I would have confidence if I were a warden that he [would] behave himself and do what he is supposed to do and accept whatever came down on him if he didn’t and not cause me any problems.” III. PRETRIAL ISSUES A.

Withdrawal and Appointment of Counsel Trial in defendant’s capital case was scheduled to start on February 14, 1989, in Contra Costa Superior Court before Judge Norman Spellberg. At that time, defendant’s counsel of record was the Contra Costa County Public Defender, Charles James, who had been appointed in May 1986. On January 30, 1989, Public Defender James filed an affidavit of conflict, stating that his office “refuses to represent defendant because of a conflict of interest.” On February 1, James appeared before Judge Spellberg and reasserted the existence of a conflict.

But the deputy public defender assigned to the case, who was also present in court, said there was no conflict, and he asked the court to let him continue as defendant’s attorney. When the court asked defendant for his view, defendant replied: “I would like to keep [the deputy] as my attorney at this point.” The court denied the deputy’s request, giving these reasons: “The Public Defender is Mr. James. He has conflicted in this matter. And if he conflicts, there is no appropriate basis for you [the deputy] to insist that you remain as [defendant’s] attorney.” The deputy, citing Harris v.

Superior Court (1977) 19 Cal.3d 786 [140 Cal.Rptr. 318, 567 P.2d 750] (Harris), insisted that defendant was entitled to a hearing on the request that the assigned deputy remain his counsel. The deputy added that he would take a leave of absence from the public defender’s office if necessary to continue as defendant’s attorney.

The trial court ruled that because of the declared conflict, “the [Office of the Contra Costa County] Public Defender no longer represents [defendant].” It appointed Attorney Stephen Houghton as counsel for defendant regarding the issues raised by the public defender’s declaration of a conflict. And it set a hearing for February 3, 1989, to consider both the possibility of defendant’s waiver of the asserted conflict and defendant’s motion for appointment of the deputy to represent him as private counsel after leaving the public defender’s office.

Before the February 3 hearing date, the prosecution filed a brief asserting that defendant had a right to know the basis for the public defender’s conflict. Defendant too filed a brief, citing Harris, supra, 19 Cal.3d 786, 140 Cal.Rptr. 318, 567 P.2d 750, as authority for the trial court to appoint as private counsel the deputy (who had offered to leave the public defender’s office) because of the “special relationship” defendant had formed with him during the two-year period that the deputy had been assigned to work on this case.

On February 3, Judge Spellberg transferred the attorney conflict matter to Superior Court Judge Michael Phelan. Judge Phelan immediately convened an in camera hearing. Present were Public Defender James, defendant, and Attorney Houghton. The court excluded the prosecutor to protect defendant’s attorney-client privilege. The court asked James why he had declared a conflict.

In response, James detailed numerous problems with his assigned deputy, including the following: Complaints by experienced investigators that the deputy had not adequately prepared the case .for trial; James’s own assessment that the deputy had not developed a coherent trial theory; and reports by former supervisors that he often had “outbursts of rage,” followed by periods in which he seemed “catatonic, unable to perform his job at all.” One former employer told James he was shocked that the deputy had been assigned a capital case, given his lengthy history of “mental health issues.” James also explained that on January 11, 1989, less than five weeks before the scheduled trial date, Rebecca Young, an attorney working as a law clerk and assisting on defendant’s case, “walked off the job” after the assigned deputy screamed at her and threatened her with a hammer.

Young told Public Defender James that the deputy had “blanched in the face, foamed in the mouth, [and] shook with rage.” He then ran from the office into a parking lot, where he “yelled about the Sapp case at the top of his lungs in earshot of the District Attorney’s office.” A few days thereafter, James received a letter from the private investigator firm most recently employed on defendant’s case. The firm had experience in some 25 capital matters.

The letter described defendant’s case as being “in a state of basic shambles” and revealed that the firm’s investigators had witnessed inappropriate outbursts and unprofessional conduct by the deputy, including a request for an investigator to impersonate a police officer when interviewing certain potential witnesses. When the investigators suggested that the deputy seemed unstable, he falsely accused them of unprofessional behavior and ordered them off the case.

Public Defender James explained to the trial court that just two weeks before the scheduled trial, he faced the following problems: The deputy had alienated everyone who was assisting him; left with “no investigator, no support staff,” he was inadequately prepared to go to trial. James called the deputy into his office and told him he was considering declaring a conflict. The deputy responded by cupping his hands over his ears and running from the office.

After discussing the problem “in the abstract” with current and former public defenders of other counties and with the president of the California Public Defenders Association, James concluded that he had no choice but to declare a conflict. Public Defender James added that although defendant wanted the deputy to continue to represent him, defendant had previously complained about the deputy. James mentioned that in January 1988, defendant wrote to James requesting that his case be assigned to a different deputy public defender.

Defendant had stated that the assigned deputy did not have defendant’s interest at heart, and that there was no longer an attorney-client relationship. Defendant wanted to have psychological issues explored but the deputy had not arranged for any psychological or psychiatric evaluation. In response to defendant’s letter, James met with defendant and persuaded him that the assigned deputy was an excellent lawyer and should remain on the case. But a year later, defendant telephoned the deputy’s assistant, Rebecca Young, and again expressed dissatisfaction with his representation.

When Young mentioned this to the deputy, he told her not to have further contact with defendant. The trial court then took a recess so Attorney Houghton could confer with defendant. Thereafter, the hearing resumed in open court. Houghton stated that he had discussed with defendant “all aspects of the—the allegations, and instances of the behavior chronicled by Mr. James,” but that defendant still wanted the deputy to represent him and therefore asked to “execute the appropriate waivers” so the court could appoint the deputy as private counsel to represent defendant.

The trial court ruled that notwithstanding Public Defender James’s declaration of a conflict of interest, “this is not factually a conflict of interest case.” Rather, as the court characterized it, defendant’s appointed counsel, Public Defender James, had “represented to the court that [his] assigned deputy is incapable of competently handling this case at trial.” The court expressed “grave misgivings” whether a defendant could waive the right to competent appointed counsel, and it found that the criteria of Harris, supra, 19 Cal.3d 786, had not been satisfied.

It then vacated the public defender’s appointment as counsel of record and denied defendant’s request for appointment of the deputy as private counsel to represent defendant. Trial in defendant’s case did not begin until some two years later, in January 1991. At trial, defendant was represented by private attorneys Stephen Houghton and Marlene Weinstein. Assisting them was Rebecca Young, who had left the public defender’s office and was working as a private attorney. Defendant now contends that the rulings by Judges Spellberg and Phelan denied him the right to counsel.

Specifically, defendant argues that he should have been permitted to waive any conflict of interest preventing representation either by the public defender’s office or by the deputy who was taken off this case, who by taking a leave from the public defender’s office could have represented defendant as private counsel.

Defendant further asserts that once the trial court vacated the public defender’s appointment as counsel of record, defendant’s “special relationship” with the assigned deputy public defender entitled him to have that attorney appointed as his counsel of record. (Harris, supra, 19 Cal.3d 786.) We are not persuaded. A criminal defendant’s right to counsel is guaranteed by both the federal Constitution’s Sixth Amendment (applicable to the states through the Fourteenth Amendment), and by California Constitution

article I,

section 15. The essential aim “is to guarantee ‘an effective advocate for each criminal defendant rather than to ensure that a defendant will inexorably be represented by the lawyer whom he prefers.’ ” (People v. Bonin (1989) 47 Cal.3d 808, 834 [254 Cal.Rptr. 298, 765 P.2d 460], quoting Wheat v. United States (1988) 486 U.S. 153, 159 [100 L.Ed.2d 140, 108 S.Ct. 1692].) Questions of appointment and removal of counsel, at least when counsel seeks to withdraw, are addressed to the trial court’s sound discretion. (People v. Daniels (1991) 52 Cal.3d 815, 846 [277 Cal.Rptr. 122, 802 P.2d 906]; Drumgo v.

Superior Court (1973) 8 Cal.3d 930, 934-935 [106 Cal.Rptr. 631, 506 P.2d 1007].) Here, defendant’s counsel of record was Contra Costa County Public Defender James. (See 59 Ops.Cal.Atty.Gen. 27 (1976) [“In cases handled by the public defender’s office, it is the officeholder who is the attorney of record.”].) As public defender, James had the authority to assign any of his deputies to represent defendant in this case (see Mowrer v. Superior Court (1969) 3 Cal.App.3d 223, 231 [83 Cal.Rptr. 125]) and also to seek his own removal from the case (Code Civ. Proc., § 284).

James asked the trial court to allow him to withdraw from defendant’s capital case based upon his evaluation that his assigned deputy was unprepared for the upcoming capital trial, for the reasons we discussed earlier in detail. Because of the extraordinary circumstances surrounding the matter, the trial court did not abuse its discretion in allowing Public Defender James to withdraw as counsel.

Defendant insists that our decision in Harris, supra, 19 Cal.3d 786, entitled him to continued representation by the assigned deputy public defender, who was willing to leave the public defender’s office and accept appointment as private counsel in defendant’s case.

Under Harris, a trial court contemplating appointment of private counsel to represent a criminal defendant must take into account whether the defendant has a preexisting relationship with an attorney willing to accept appointment. (Id. at p. 799.) But even when such a relationship exists, Harris acknowledges that a trial court need not appoint that attorney when there are “countervailing considerations of comparable weight.” (Ibid.) Here, the facts described by Public Defender James at the in camera hearing raised serious concerns about his assigned deputy’s ability to competently represent defendant, thus constituting the requisite countervailing considerations.

Under these circumstances, defendant suffered no infringement of his constitutional right to counsel because the trial court refused to appoint the attorney as defendant’s counsel. Also of no assistance to defendant is Smith v. Superior Court (1968) 68 Cal.2d 547 [68 Cal.Rptr. 1, 440 P.2d 65]. In that case, this court set aside a trial court’s order removing a private attorney from the retrial of a capital case for purported incompetence. The attorney had successfully represented the defendant in his automatic appeal, securing a complete reversal.

The trial court’s removal of the attorney suggested not so much that the attorney lacked the ability to competently try the case as it did the existence of a personality conflict between the trial judge and the attorney. (Id. at pp. 557-558.) That is not the situation here. Defendant points out that the assigned deputy was not present at the in camera hearing before Judge Phelan on February 3, 1989, and thus had no opportunity to counter the version of events described by Public Defender James.

We note that on February 1, 1989, the deputy, represented by counsel, appeared before Judge Spellberg and argued that no conflict prevented defendant’s representation by the office of the public defender, and alternatively, that the trial court should appoint him personally as private counsel to represent defendant. At that hearing and again on February 3, Judge Spellberg ruled that Public Defender James, not James’s deputy, was defendant’s attorney of record, and that the deputy therefore lacked standing to oppose James’s motion to withdraw for a conflict of interest.

When Judge Spellberg then transferred the matter to Judge Phelan, the deputy did not appear before Judge Phelan. Defendant, who was present and represented by counsel, raised no objection to Judge Phelan’s deciding the matter without hearing from the deputy. On these facts, defendant cannot complain that his rights were violated. B. Motions to Sever Murder Counts Before trial, defendant twice sought separate trials on each of the three murder charges. The trial court denied those requests, and the same jury heard evidence of all three offenses in a single trial.

Defendant contends that the joint trial of all three murder charges was fundamentally unfair, thus entitling him to reversal. We disagree.

Section 954, which governs joinder of counts in a single trial, provides: “An accusatory pleading may charge . . . two or more different offenses of the same class of crimes or offenses, under separate counts . . . .” These statutory requirements for joinder were met here because the three murder counts were crimes “of the same class.” (People v. Mason (1991) 52 Cal.3d 909, 933 [277 Cal.Rptr. 166, 802 P.2d 950].) But

section 954 also provides that “the court in which a case is triable, in the interests of justice and for good cause shown, may in its discretion order that the different offenses ... be tried separately.” We review for abuse of discretion a trial court’s decision not to try the offenses separately, that is, not to sever charges under this provision. (People v. Gutierrez (2002) 28 Cal.4th 1083, 1120 [124 Cal.Rptr.2d 373, 52 P.3d 572]; People v.

Mayfield (1997) 14 Cal.4th 668, 720 [60 Cal.Rptr.2d 1, 928 P.2d 485].) “ ‘ “The burden is on the party seeking severance to clearly establish that there is a substantial danger of prejudice requiring that the charges be separately tried.” [Citation.] ...[$]...

Refusal to sever may be an abuse of discretion where: (1) evidence on the crimes to be jointly tried would not be cross-admissible in separate trials; (2) certain of the charges are unusually likely to inflame the jury against the defendant; (3) a “weak” case has been joined with a “strong” case, or with another “weak” case, so that the “spillover” effect of aggregate evidence on several charges might well alter the outcome of some or all of the charges; and (4) any one of the charges carries the death penalty or joinder of them turns the matter into a capital case.’ ” (People v.

Bradford (1997) 15 Cal.4th 1229, 1315 [65 Cal.Rptr.2d 145, 939 P.2d 259].) With respect to the first factor, defendant contends that if the three murder counts had been tried separately, evidence of the other two would not have been cross-admissible in any other trial because the crimes bore no common identifying characteristics and thus were not probative of any of the factors listed in Evidence Code

section 1101, subdivision (b). But, as we explain, even if we assume that the standards for cross-admissibility in the prosecution’s case-in-chief were not satisfied here (see People v. Mason, supra, 52 Cal.3d at p. 934), the evidence of the other two murders would have been cross-admissible on rebuttal in each other case if tried separately. This rebuttal evidence would have shown that, with respect to each murder defendant confessed to, he knew the victim well (Abono was his best friend from high school; Duarte was his former girlfriend; Weber was a drug dealer with whom he did business).

And evidence independent of defendant’s confession linked him to each of the crimes (Abono was last seen going to buy drugs from defendant; when Duarte disappeared, police searched defendant’s van and found caked mud and blood of her blood type; Weber left for a drug-buying trip with defendant days before his body was found).

The evidence of the other murders, including defendant’s confessions, would have been admissible to refute any contention that defendant frequently made false confessions to murders or, if defendant presented a mental-state defense, to refute any contention that premeditation and deliberation was absent from any murder. Accordingly, defendant suffered no prejudice from the trial court’s denial of the severance motion. Defendant argues that because Abono’s body was never found, the evidence as to that murder case was relatively weaker than the evidence supporting the other two counts of murder.

Thus, defendant contends, the trial court abused its discretion in not severing the Abono murder count from the other two murders. We are not persuaded. As just discussed, the Abono killing resembled the other two murders not only because defendant confessed to it, but also because Abono, like the other victims, was close to defendant. The circumstances of the Abono murder, therefore, satisfied the requirements for cross-admissibility to rebut the defense claim that defendant falsely confessed to the killings, thereby dispelling “ ‘any inference of prejudice.’ ” (People v.

Sandoval (1992) 4 Cal.4th 155, 173 [14 Cal.Rptr.2d 342, 841 P.2d 862].) As earlier explained, in determining whether a trial court abused its discretion in denying a severance motion, we consider whether a capital offense has been linked with a noncapital offense, and most particularly whether the linkage “ ‘turns the matter into a capital case.’ ” (People v. Bradford, supra, 15 Cal.4th at p. 1315.) Here, as defendant points out, he could not be sentenced to death for killing Abono because in 1975, when Abono was killed, there was no death penalty law in effect in California.

Accordingly, defendant contends that trying that noncapital murder count with the two capital murder counts was an abuse of discretion by the trial court. We disagree. Although the first degree murder conviction on the count involving Abono allowed the jury to find the existence of the multiple murder special circumstance (§ 190.2, subd. (a)(3) [“The defendant, in this proceeding, has been convicted of more than one offense of murder in the first or second degree”]), that conviction was not crucial to the multiple-murder special-circumstance finding.

The jury in the same proceeding also returned first degree murder verdicts on the Duarte and Weber murder counts, both charged as capital offenses. These verdicts would, even if the same jury had not decided the charge involving Abono, have provided the basis for a true finding on the multiple-murder special-circumstance allegation. Accordingly, the trial court’s decision to allow the jury in the same proceeding that involved the murders of Weber and Duarte to also decide the charge involving Abono did not result in any prejudice to defendant.

Having concluded that defendant suffered no prejudice from the joint trial of the three murder counts, we also reject his contention that the joint trial violated his due process rights. (See United States v. Lane (1986) 474 U.S. 438, 446, fn. 8 [88 L.Ed.2d 814, 106 S.Ct. 725] [“Improper joinder does not, in itself, violate the Constitution” but rather “rise[s] to the level of a constitutional violation only if it results in prejudice so great as to deny a defendant his Fifth Amendment right to a fair trial”]; People v. Mendoza (2000) 24 Cal.4th 130, 162 [99 Cal.Rptr.2d 485, 6 P.3d 150].) C.

Failure to Bifurcate Trial on the Charge of Felon in Possession of a Concealable Firearm In addition to the three murder counts, defendant was convicted of a 1985 violation of

section 12021. In 1985, that provision prohibited any person who had been convicted of a felony offense from possessing any “firearm capable of being concealed upon the person.” (Stats. 1983, ch. 1092, § 326.5, p. 4062.) In July 1981, defendant had been convicted of the felony of recklessly burning an inhabited structure (§ 452, subd. (b)), the house of murder victim Duarte, who had disappeared in January of that same year. Before trial, the defense moved to “bifurcate” the trial on the felon in possession of a firearm charge.

Specifically, counsel stated that defendant was “prepared to . . . waive jury on that [charge] . . . and have the Court. . . out of the presence of the jury” decide it. The trial court, citing People v. Valentine (1986) 42 Cal.3d 170 [228 Cal.Rptr. 25, 720 P.2d 913] (Valentine), denied the request.

It stated that the question of being a felon in possession of a firearm was for “the jury to determine,” and that case law “has only given us one area where we can adjust that, ... if there is a stipulation as to the defendant’s status as an ex-felon, then the nature of the particular felony can be withheld from the jury.” Defendant thereafter agreed to stipulate that he had been convicted of a felony, and he asked the court “to sanitize” the felon-in-possession charge such that “the details” of the underlying felony would be “withheld from the jury.” At the end of the guilt phase trial, the court instructed the jury under CALJIC No. 12.44 that “the previous felony conviction has already been established ... so that no further proof of that fact is required.” Defendant now contends that the trial court’s ruling on the motion to bifurcate was error requiring reversal.

According to defendant, the trial court misinterpreted Valentine, supra, 42 Cal.3d 170, as allowing only two options when a prior conviction is a substantive element of a current charge: Either the defendant admits to having a prior conviction and the court “sanitizes” the prior by keeping from the jury the nature of the offense, or the prosecution proves the prior conviction in open court. Defendant argues that Valentine allows a third option-, full bifurcation of trial on the charge involving a prior conviction by having the trial court decide the charge outside the jury’s presence.

Defendant misconstrues Valentine. This court’s 1986 decision in Valentine, supra, 42 Cal.3d 170, interpreted

article I,

section 28, subdivision (

f) of the California Constitution, added to the Constitution by Proposition 8, an initiative that the California electorate passed in 1982. It states: “When a prior felony conviction is an element of any felony offense, it shall be proven to the trier of fact in open court.” (Cal. Const., art. I, § 28, subd. (f) (article I,

section 28(f)).) Valentine concluded that the language was directed at People v. Hall (1980) 28 Cal.3d 143 [167 Cal.Rptr. 844, 616 P.2d 826], which held that when an element of a charged offense requires proof that the defendant has a felony conviction, and the defendant offers to stipulate to the prior conviction, it is error to inform the jury either of the fact that the defendant has a prior felony conviction or the nature of the felony. (Id. at pp. 153-154.) Valentine held that

article I,

section 28(

f) eliminated “the per se rule of Hall” by requiring that the jury be advised that the defendant has suffered a prior felony conviction if such felony conviction is an element of a current charge. (Valentine, supra, 42 Cal.3d at p. 173.) But if the defendant offers to stipulate to a prior felony conviction,

article I,

section 28(

f) allows evidence of the nature of that felony to be withheld from the jury. (Valentine, supra, at p. 173.) Thus, as the trial court properly ruled in this case, Valentine allows one of two alternatives when a defendant’s prior felony conviction is an element of a charged crime:

(1) The prosecution can prove the conviction in open court, and that proof can include both the fact that the defendant has previously been convicted of a felony offense as well as the nature of the felony involved; or (2) the defendant can stipulate to having a felony conviction and thereby keep from the jury the nature of the particular felony.

In insisting that Valentine allows a third option, that of full bifurcation of trial on the charge of being a felon in possession of a concealable firearm, defendant quotes this language from Valentine: “[T]he court must balance the legitimate benefits ... of a consolidated trial against the likelihood that disclosure of ex-felon status in a joint trial will affect the jury’s verdict on charges to which that status is irrelevant.” (Valentine, supra, 42 Cal.3d at p. 180, fn. 3.) Contrary to defendant’s assertion here, that language pertains not to a motion to bifurcate trial on a charge that requires proof of a prior felony conviction (the motion brought here), but to a motion to sever charges properly joined under

section 954. The relevant portion of Valentine's footnote 3 states in full: “[Defendant argues that the trial court should at least have granted his motion to sever the firearm-possession count from the robbery charge in order to prevent disclosure of defendant’s criminal record from affecting the jury’s deliberations on the latter crime. We need not resolve that contention, since we hold that disclosure of the nature of defendant’s priors was reversible error as to all counts. [|] . . . [W]e decline to rule that such a procedure is mandatory in all cases.

When the joinder statute (§ 954) would otherwise permit consolidation of charges, a trial court should, if requested, carefully exercise its discretion whether to try [the firearm possession] count separately ‘in the interests of justice.’ ” (Valentine, supra, 42 Cal.3d at p. 180, fn. 3.) This is followed by the sentence on which defendant relies, which states that a court considering such a severance request must balance the various interests. (Ibid.) Because this court, in Valentine expressly declined to decide whether the trial court in that case abused its discretion in failing to grant the defendant’s severance motion, its discussion of severance was dictum, as defendant acknowledges. (See Palmer v.

GTE California, Inc. (2003) 30 Cal.4th 1265, 1278 [135 Cal.Rptr.2d 654, 70 P.3d 1067] [“ ‘an opinion is not authority for a proposition not therein considered’ ”]; People v. Scheid (1997) 16 Cal.4th 1, 17 [65 Cal.Rptr.2d 348, 939 P.2d 748] [same].) Moreover, defendant concedes he did not move to sever the firearm-possession count from the three murder counts. He asserts, however, that although the Valentine dictum discussed only severance explicitly “its rationale . . . would apply to permitting full bifurcation (a mini-trial following the guilt trial on the main charges).” Not so.

In footnote 3 in Valentine this court expressly rejected the idea that

article I, “section 28(

f) should be interpreted to require bifurcated trials, with proof of [prior felony convictions] made only to the judge, who would be the ‘trier of fact’ for this limited purpose.” (Valentine, supra, 42 Cal.3d at p. 179, fn. 3.) To summarize: Valentine, supra, 42 Cal.3d 170, allows the trial court only two options when a prior conviction is a substantive element of a current charge: Either the prosecution proves each element of the offense to the jury, or the defendant stipulates to the conviction and the court “sanitizes” the prior by telling the jury that the defendant has a prior felony conviction, without specifying the nature of the felony committed.

These are the same two options the trial court here offered defendant. Accordingly, there was no error. Defendant accuses his trial counsel of rendering ineffective assistance, because, faced with those two options, counsel chose to' have the court sanitize the prior felony conviction. Defendant contends that counsel’s decision not to reveal to the jury the nature of defendant’s prior felony conviction did him more harm than good for this reason: The prior pertained to the relatively minor offense of recklessly burning an inhabited dwelling.

Because the jury had already heard evidence that defendant had set fire to Duarte’s house, defendant argues that the jury might have speculated that his prior felony conviction was for an offense other than setting fire to Duarte’s house, possibly something far more serious, such as murder.

Preliminarily, we note that nothing in the record supports this conjecture by defendant. “To establish a violation of the constitutional right to effective assistance of counsel, a defendant must show both that his counsel’s performance was deficient when measured against the standard of a reasonably competent attorney and that this deficient performance caused prejudice in the sense that it ‘so undermined the proper functioning of the adversarial process that the trial cannot be relied on as having produced a just result.’ (Strickland v.

Washington (1984) 466 U.S. 668, 686 [80 L.Ed.2d 674, 104 S.Ct. 2052]; see also People v. Wader (1993) 5 Cal.4th 610, 636 [20 Cal.Rptr.2d 788, 854 P.2d 80].) If a defendant has failed to show that the challenged actions of counsel were prejudicial, a reviewing court may reject the claim on that ground without determining whether counsel’s performance was deficient. (Strickland v. Washington, supra, 466 U.S. at p. 697.)” (People v.

Kipp (2001) 26 Cal.4th 1100, 1122-1123 [113 Cal.Rptr.2d 27, 33 P.3d 450].) In determining whether an attorney’s conduct so affected the reliability of the trial as to undermine confidence that it “produced a just result” (Strickland v. Washington, supra, 466 U.S. at p. 686), we consider whether “but for” counsel’s purportedly deficient performance “there is a reasonable probability the result of the proceeding would have been different.” (People v. Cash (2002) 28 Cal.4th 703, 734 [122 Cal.Rptr.2d 545, 50 P.3d 332]; see Strickland v. Washington, supra, at p. 694.) That standard cannot be met here.

Given defendant’s confessions to the three murders in this case, and the physical and circumstantial evidence indicating that he was the killer in each instance, no reasonable probability exists that the jury would have acquitted him had it learned that his prior felony conviction was for reckless burning of an occupied dwelling rather than some other and perhaps more serious crime. D. Admissibility of Defendant’s Confessions Before trial, defendant moved to suppress evidence of statements he had made to law enforcement officers shortly after his April 25, 1986, arrest.

After hearing testimony, the trial court granted the motion with respect to statements defendant made during interrogation on April 25, but denied it with respect to all the statements defendant made after he initiated contact with law enforcement officers on the evening of April 26. Thus, at the guilt phase of defendant’s capital trial, the jury heard evidence of defendant’s confessions to the murders of Weber, Duarte, and Abono, including evidence that he led detectives to the locations of those killings.

Defendant contends that the introduction of this evidence violated the self-incrimination and due process clauses of the federal and state Constitutions. (U.S. Const., 5th & 14th Amends.; Cal. Const., art. I, §§ 7, 15.) Specifically, he claims the police violated his rights under Miranda v. Arizona (1966) 384 U.S. 436 [16 L.Ed.2d 694, 86 S.Ct. 1602] (Miranda), on April 25, 1986, and that as a result his confessions on April 26, 27, and 28 must be deemed involuntary. He also asserts that his confessions were involuntary because they were coerced. We disagree. 1.

Factual background Evidence at the suppression hearing established that on the morning of April 25, 1986, Nevada County Sheriff’s deputies arrested defendant on a warrant issued by Butte County. On the way to the Nevada County jail, defendant volunteered that he “wanted to talk and clear things up,” and that he could tell the deputies “about 20 murders.” About an hour after defendant’s arrival at the jail, Sergeant Steven McCulloch of the Colusa County Sheriff’s Department asked to talk with him about the Weber killing.

Also present was Detective Bill Elliott of the Butte County Sheriff’s Department, who was investigating the disappearance of defendant’s mother. Sergeant McCulloch advised defendant of his Miranda rights (to remain silent and to have an attorney); defendant said he understood those rights but added that if the detectives wanted to talk about murders “maybe I should have an attorney.” McCulloch continued to question defendant, and then Detective Elliott said he wanted to talk about the disappearance of defendant’s mother.

When defendant refused, Elliott appealed to him to reveal where he had hidden his mother’s body so she could have a proper burial. Defendant became emotional, was “on the verge of tears,” and did not respond, whereupon Elliott left the room. Shortly thereafter, Detective Michael Tye of the Richmond Police Department arrived to question defendant about Duarte. Before entering the interview room, he spoke with Detective Elliott, who mentioned that defendant had said something about “possibly needing an attorney.” When Tye joined the questioning, he ascertained that McCulloch had given defendant Miranda advisements.

Tye then spoke with defendant for about two hours. He mentioned defendant’s brother Mike, a fellow Richmond police officer, stressing that defendant’s involvement in murders was “having some adverse effects on Mike,” and that defendant could help his brother by telling the truth about what had happened to the victims.

After a two-hour dinner break, Detective Tye talked to defendant for about another half-hour, at which point defendant said he “wanted to have an attorney.” Tye gave defendant his card and told him to “think about it overnight,” adding that before the homicide investigators could again talk to defendant with or without an attorney being present, defendant would have to “get in contact” with them.

The next evening, April 26, Nevada County Sheriff’s Deputy Mary Fryback was on duty in the jail when defendant called her to his cell and said he was ready to talk to the investigators about “those murders that those guys were asking me about yesterday.” Fryback told defendant that the investigators had all returned to their home counties and thus were not available to interview him.

Defendant insisted that the investigators must have “left a message where to get them,” and that Fryback should “go call them . . . now.” Fryback alerted her superior, Deputy Sheriff Troy Arbaugh, who telephoned Sergeant McCulloch, Detectives Elliott, and Tye, relaying to them defendant’s message. (Deputy Arbaugh would later testify that the investigators had asked him to make sure that defendant “in fact did want to speak with them about their cases” before they drove all the way back to Nevada County.) Thereafter, without advising defendant of his Miranda rights, Arbaugh inquired whether defendant was serious about talking to the investigators about the murders.

Defendant replied; “I want to admit to three murders, two in Contra Costa County and one in Colusa County. I want to show where two of the bodies were buried and I will show where my mother is buried. I didn’t kill her, but she was killed because of me, [and] I dumped the guy in the bay that did kill her.” Defendant added that he wanted “to get it all behind” him and did not want “any attorneys” involved. A short while later, defendant spoke for about 10 minutes by telephone with Detective Tye of the Richmond Police Department. That conversation was tape-recorded.

With no questioning by Tye, defendant stated: “I just want to get this shit over with. I’ll give you the locations of what you guys want.” When Tye responded, “Okay,” defendant said: “[T]he main reason is you’ve convinced me that it would be best for Mike [his police officer brother].

That’s the main reason I’m doing this.” Defendant added: “I’ll tell you right now I killed Abono; I killed Weber; I killed Duarte; but I didn’t kill my mother, but because of me, she died; and the person that killed her, I killed, and I’ll tell you where he’s at.” Defendant then promised that Detective Tye would not “drive up here and drive back-frustrated again,” to which Tye responded: “I’ll be there first thing in the morning.” The next morning, April 27, Detective Tye arrived at the Nevada County jail before 9:00 a.m. to question defendant.

He was soon joined by Sergeant McCulloch, Detective Elliott, and Tony Koester, an investigator for the Butte County District Attorney’s Office. Tye readvised defendant of, and defendant waived, his Miranda rights. Tye commented that the Miranda waiver would “carry throughout the day,” and he suggested it would be “a long day” of questioning. And Tye assured defendant that if at any time during that questioning, defendant did not want “to talk anymore,” to just say so, and questioning would stop.

Tye noted that he was “involved in the Duarte case,” adding that “one of [his] main reasons” for wanting to talk to defendant was to convey how defendant’s brother Mike, a Richmond police officer, was doing. Tye told defendant: “I thought that you should take that into consideration when you decided whether or not you wanted to talk with us.” Defendant replied that he still wanted to talk to the investigators. Defendant then made this statement: “I killed John Abono .... I did it for personal reasons. I killed Elizabeth Duarte for money. I was paid to kill her. I killed Robert Weber for money.

I was paid to kill him.” Later that same day, April 27, the investigators drove with defendant to Contra Costa County, and he directed them to the areas where he had killed and buried Abono and Duarte. The next day, April 28, the investigators took defendant to Colusa County, and he led them to the area where he had killed Weber and left the body. At each location and in later interviews, defendant was readvised of and waived his Miranda rights, and continued to provide details about the three killings. 2. Pertinent legal standards a.

Miranda The privilege against self-incrimination provided by the Fifth Amendment of the federal Constitution and by

article I,

section 15 of the California Constitution “is protected in ‘inherently coercive’ circumstances by the requirement that a suspect not be subjected to custodial interrogation unless he or she knowingly and intelligently has waived the right to remain silent, the presence of an attorney, and, if indigent, to appointed counsel.” (People v. Cunningham (2001) 25 Cal.4th 926, 992 [108 Cal.Rptr.2d 291, 25 P.3d 519] (Cunningham); see Dickerson v.

United States (2000) 530 U.S. 428, 439-440 [147 L.Ed.2d 405, 120 S.Ct. 2326]; Miranda, supra, 384 U.S. 436.) “ ‘ “If a suspect indicates ‘in any manner and at any stage of the process,’ prior to or during questioning, that he or she wishes to consult with an attorney, the defendant may not be interrogated.” ’ ” (People v. Storm (2002) 28 Cal.4th 1007, 1021 [124 Cal.Rptr.2d 110, 52 P.3d 52].) Rather, “ ‘the interrogation must cease until an attorney is present.’ ” (Edwards v.

Arizona (1981) 451 U.S. 477, 482 [68 L.Ed.2d 378, 101 S.Ct. 1880].) Moreover if, in violation of this rule, interrogation continues of an in-custody suspect who has asked for but has not been provided with counsel, the suspect’s responses are presumptively involuntary and therefore “are inadmissible as substantive evidence at trial.” (Cunningham, supra, at p. 993; see McNeil v.

Wisconsin (1991) 501 U.S. 171, 176-177 [15 L.Ed.2d 158, 111 S.Ct. 2204].) Such exclusion is not required, however, when the “suspect personally ‘initiates further communication, exchanges, or conversations’ with the authorities.” (Cunningham, supra, at p. 992, quoting Edwards v. Arizona, supra, at pp. 484—485.) The rule that interrogation must cease because the suspect requested counsel does not apply if the request is equivocal; “[r]ather, the suspect must unambiguously request counsel.” (Davis v. United States (1994) 512 U.S. 452, 459 [29 L.Ed.2d 362, 114 S.Ct. 2350].) b.

Voluntariness The Fourteenth Amendment of the federal Constitution and

article I,

section 7 of the California Constitution make “inadmissible any involuntary statement obtained by a law enforcement officer from a criminal suspect by coercion.” (People v. Neal (2003) 31 Cal.4th 63, 67 [1 Cal.Rptr.3d 650, 72 P.3d 280]; see People v. Jimenez (1978) 21 Cal.3d 595, 611 [147 Cal.Rptr. 172, 580 P.2d 672].) “Voluntariness does not turn on any one fact, no matter how apparently significant, but rather on the ‘totality of [the] circumstances.’ ” (People v. Neal, supra, at p. 79; Withrow v.

Williams (1993) 507 U.S. 680, 688-690 [23 L.Ed.2d 407, 113 S.Ct. 1745].) Under federal standards, the prosecution “must demonstrate the voluntariness of a confession by a preponderance of the evidence.” (People v. Bradford (1997) 14 Cal.4th 1005, 1033 [60 Cal.Rptr.2d 225, 929 P.2d 544], citing Colorado v. Connelly (1986) 479 U.S. 157, 168 [93 L.Ed.2d 473, 107 S.Ct. 515].) California courts use this standard for crimes committed after the June 8, 1982, enactment of

article I,

section 28 of the California Constitution, which as pertinent here prohibits the exclusion in criminal cases of relevant evidence not required to be excluded under the federal Constitution. (People v. Markham (1989) 49 Cal.3d 63, 71 [260 Cal.Rptr. 273, 775 P.2d 1042]; see In re Lance W. (1985) 37 Cal.3d 873 [210 Cal.Rptr. 631, 694 P.2d 744].) But for crimes committed before

article I,

section 28’s June 8, 1982, enactment, the prosecution “must prove voluntariness beyond a reasonable doubt.” (People v. Thompson (1990) 50 Cal.3d 134, 166 [266 Cal.Rptr. 309, 785 P.2d 857]; People v. Jimenez, supra, 21 Cal.3d at p. 608.) Here, the December 1975 murder of Abono, and the January 1981 murder of Duarte were both committed before the enactment of

article 1,

section 28. Thus, for those two crimes the prosecution had to prove that defendant’s statements made after he asserted his right to counsel were voluntary beyond a reasonable doubt. Only for the August 1985 killing of Weber did the lower preponderance of the evidence standard for voluntariness apply. In ruling on defendant’s suppression motion in this case, the trial court applied the stricter beyond a reasonable doubt standard in determining that defendant had voluntarily confessed to all three murders.

We “ ‘independently determine’ ” voluntariness while accepting “ ‘the trial court’s resolution of disputed facts and inferences, and its evaluations of credibility, if supported by substantial evidence.’ ” (People v. Storm, supra, 28 Cal.4th at pp. 1022-1023.) Nonetheless, we agree with the trial court that the prosecution proved beyond a reasonable doubt that defendant voluntarily confessed to all three murders. We likewise conclude that the confessions were not the tainted by a violation of defendant’s Miranda rights.

Defendant’s initial effort to invoke his right to counsel on April 26, 1986, shortly after his arrival at the Nevada County jail was equivocal and therefore inadequate to invoke the rule that all questioning must cease. (Davis v. United States, supra, 512 U.S. at p. 459.) Later that evening, when defendant unequivocally told Detective Tye he wanted an attorney, Tye stopped his questioning and properly advised defendant that none of the homicide investigators could question him unless defendant initiated contact with them. (Edwards v.

Arizona, supra, 451 U.S. at p. 482.) Some 24 hours later, defendant summoned a jail guard and asked for the homicide investigators to come back so he could admit to three murders. (Cunningham, supra, 25 Cal.4th at p. 992.) Thereafter, he gave investigators a detailed account of the murders and led them to the crime scenes. Defendant was over 30, obviously intelligent and well-acquainted with the criminal justice system. The totality of circumstances show his decision to summon the investigators was not the result of coercion. On these facts, voluntariness is established beyond a reasonable doubt. (Cf. People v.

Neal, supra, 31 Cal.4th at pp. 80-81.) 3. California law before June 8, 1982 Citing People v. Burton (1971) 6 Cal.3d 375, 382 [99 Cal.Rptr. 1, 491 P.2d 793], and People v. Randall (1970) 1 Cal.3d 948, 955 [83 Cal.Rptr. 658, 464 P.2d 114], defendant contends that under California law as it existed before the June 8, 1982, enactment of

article I,

section 28 of the California Constitution (prohibiting the exclusion in criminal cases of relevant evidence not required to be excluded under the federal Constitution), an equivocal invocation of the right to counsel was sufficient to invoke the California Constitution’s self-incrimination clause.

Because the trial court suppressed defendant’s statements to the detectives on April 25, 1986 based on his equivocal assertion “maybe I should have an attorney,” defendant argues here that his later confessions to the three murders should also have been suppressed as “the tainted product of’ the detectives’ unlawful interrogation of him on April 25. (See People v. Sims (1993) 5 Cal.4th 405, 445 [20 Cal.Rptr.2d 537, 853 P.2d 992] [applying a “fruit of the poisonous tree” analysis to a “subsequent confession”]; but see People v. Bradford, supra, 14 Cal.4th at p. 1041, fn. 3 [rejecting that analysis].) We disagree.

In addressing this argument, we assume that the trial court was correct in suppressing defendant’s April 25 statements to the detectives as necessary to protect his California constitutional right against self-incrimination with respect to the murders of Abono and Duarte, both of which predated the enactment of

article I,

section 28. And we also assume that California law would require the suppression of a later confession that was the tainted product of statements made after an earlier equivocal assertion of the right to counsel. We conclude, however, that defendant’s confessions to the three murders on April 26, 27, and 28 were not the tainted product of his April 25 interrogation because an intervening independent act by defendant broke any possible causal link between the April 25 interrogation and his later confessions. (See People v.

Rich (1988) 45 Cal.3d 1036, 1081 [248 Cal.Rptr. 510, 755 P.2d 960] [explaining that “ ‘an intervening independent act by defendant’ ” will “purged any taint from the initial suppressed confession”]; People v. Sesslin (1968) 68 Cal.2d 418, 428 [67 Cal.Rptr. 409, 439 P.2d 321].) As we have already discussed, during questioning by Detective Tye on the evening of April 25, defendant unequivocally said he wanted an attorney. Tye immediately stopped questioning and told defendant there could be no firrther questioning by any of the homicide investigators unless defendant initiated contact with them.

The next evening, defendant did so. Defendant’s confessions to the murders introduced against him at his capital trial were made after defendant’s independent intervening act of summoning the homicide detectives. 4. Other contentions Defendant further contends that his statements should have been suppressed on the independent ground that they were obtained in violation of sections 821 and 825.

At the time of defendant’s 1986 arrest, the former provided that when a defendant is arrested on a warrant “in another county,” the arresting officer must advise the defendant “of his right to be taken before a magistrate in that county.” (§ 821.) The latter provided for the defendant to be taken “before the magistrate without unnecessary delay, and, in any event, within two days after his arrest, excluding Sundays and holidays.” (§ 825, as amended by Stats. 1961, ch. 2209, § 1, p. 4554.) Defendant observes that he was arrested in Nevada County on an outstanding felony warrant issued by Butte County for the charge of felon in possession of a concealable firearm, and that his arrest was on April 25, 1986, a Friday.

On the evening of Saturday, April 26, defendant first confessed to killing Weber, Duarte, and Abono, and he was arraigned in Contra Costa County on murder charges involving those killings on Wednesday, April 30. In the trial court, defendant complained of the four-day delay between his April 26 murder confessions and his arraignment on those murders.

At the hearing on defendant’s suppression motion, Detective Tye attributed that delay to efforts to coordinate the cases with the involved counties, which included Contra Costa (where defendant killed Duarte and Abono) and Colusa (where defendant killed Weber), as well as Butte County (where defendant’s mother’s body was found), and the decision whether to charge defendant with a fourth count of murder involving his mother. In this court, defendant complains of the five-day delay between his April 25 arrest and his April 30 arraignment but concedes that he did not object to that delay in the trial court.

Accordingly, the point is not preserved for appeal. In any event, it lacks merit. Even before the enactment of California Constitution

article I,

section 28, which, as pertinent here, limited the suppression of relevant evidence in criminal cases (see In re Lance W., supra, 37 Cal.3d 873), delay in arraignment would justify suppressing a confession only upon a defendant’s showing that the confession was the product of an illegal detention. (People v. Thompson (1980) 27 Cal.3d 303, 329-330 [165 Cal.Rptr. 289, 611 P.2d 883].) Defendant made no such showing here, nor could he, because the murder confessions were not the product of any illegal delay in arraigning him on the Butte County felon-in-possession charge. Arraignment on that charge on Monday, April 28, would have satisfied

section 825’s “two-day” timeliness requirement. By that time, however, defendant had already given detailed confessions to the three murders, and he had led authorities to the locations of the Duarte and Abono killings. On these facts, defendant’s confessions were not the product of the prosecution’s failure to timely arraign him on the firearm-possession warrant on Monday, April 28. With respect to defendant’s related claim that his detention violated the search and seizure clauses of the federal and state Constitutions (U.S. Const., 4th Amend.; Cal. Const., art. I, § 13; County of Riverside v.

McLaughlin (1991) 500 U.S. 44 [114 L.Ed.2d 49, 111 S.Ct. 1661]), that issue was not raised in the trial court and thus is not properly before us (People v. Earp (1999) 20 Cal.4th 826, 882 [85 Cal.Rptr.2d 857, 978 P.2d 15]). In any event, it is meritless. As we have already explained, defendant’s detention after his arrest on an outstanding warrant was not unlawful. E. Withholding Access to a Reporter’s Unpublished Notes of an Interview with Defendant 1.

Trial court proceedings Some two weeks after defendant’s arrest in this case, news reporter Erin Hallissy interviewed him for about two hours in the Contra Costa County jail. On May 10, 1986, Hallissy’s

article entitled 7 Killed Many for Pay, Says Sapp appeared on the front page of the Contra Costa Times newspaper. In January 1987, defendant served Hallissy with a subpoena demanding her presence at the preliminary hearing then scheduled for February 9, 1987, and requiring her to bring her “notes, memoranda, tapes of interviews, and statements taken at the interview.” On Hallissy’s motion asserting the newsperson’s shield law (Evid.

Code, § 1070), the magistrate quashed the subpoena, ruling that Hallissy could provide no relevant, admissible evidence for purposes of the preliminary hearing, and that defendant was not entitled to use that hearing “for the purpose of discovery.” At the preliminary hearing, the magistrate held defendant to answer on the charges in this case. Thereafter, defendant moved in the superior court to dismiss the information. (§ 995.) Among the grounds asserted was the magistrate’s quashing of the Hallissy subpoena.

According to defendant, the magistrate’s order violated defendant’s “substantial right[s]” by preventing him from calling a witness at the preliminary hearing who could assist in the preparation of his defense. Specifically, defendant asserted that because most of the evidence against him “comes from [his] own mouth,” and he “says different things at different times,” all of his statements to Hallissy regarding the charged crimes would be relevant to preparing his defense.

The superior court, noting that the source of the information sought to be protected was “the very person seeking disclosure,” ruled that the newsperson’s shield law did not apply to Hallissy’s notes of her interview with defendant. On that basis, without setting aside the information, it remanded the matter to the magistrate to reconvene the preliminary hearing. At that hearing, Hallissy appeared as a witness. Defense counsel sought to question her about unpublished information obtained in her interview with defendant, but she refused to answer the questions.

Accordingly, the magistrate held Hallissy in contempt of court and ordered her into custody. On Hallissy’s petition to this court, we stayed execution of the contempt order and transferred the matter to the Court of Appeal, directing it to issue an alternative writ. 2. Court of Appeal proceedings The Court of Appeal, in a published decision, Hallissy v.

Superior Court (1988) 200 Cal.App.3d 1038 [248 Cal.Rptr. 635] (Hallissy), issued a peremptory writ of mandate, vacating the superior court’s remand order and the magistrate’s contempt order. (Id. at p. 1046.) The court concluded that the remand to the magistrate was unauthorized by

section 995a, subdivision (b)(1), which allows a remand without setting aside an information only for the correction of “ ‘minor errors of omission, ambiguity, or technical defect[s].’ ” (Hallissy, supra, at pp. 1042-1043, italics in Hallissy omitted.) The Court of Appeal nonetheless, as “guidance [for] the trial court,” addressed issues pertaining to the newsperson’s shield law and the magistrate’s order. (Id. at p. 1044.) Hallissy described the newsperson’s shield law as generally conferring immunity from contempt “when a nonparty witness refuses to disclose . . . covered information.” (Hallissy, supra, 200 Cal.App.3d at p. 1045.) Notwithstanding that immunity, the court added, a criminal defendant may be entitled to discover information otherwise subject to the shield law. (Ibid.) Quoting Hammarley v.

Superior Court (1979) 89 Cal.App.3d 388 [153 Cal.Rptr. 608] (Hammarley), the Hallissy court noted that “ ‘the burden is on the party seeking to avoid the [newsperson’s] privilege competently to demonstrate not only that the evidence sought is relevant and necessary to his case, but that it is not available from a source less intrusive upon the privilege.’ ” (Hallissy, supra, at pp. 1045-1046.) That burden requires a defendant to show “ ‘a reasonable possibility that the evidence sought might result in his exoneration.’ ” (Id. at p. 1046.) The Court of Appeal in Hallissy concluded that defendant had not satisfied that burden.

It stated: “Sapp comes close to meeting only one of the several concomitants of the presentation described in Hammarley. Arguably he approaches an adequate showing of relevancy: he wishes to attack his own credibility by using inconsistent statements that he made to the reporter during the interview. But he has made no attempt to demonstrate that this particular item of evidence, if it exists, is necessary to his case, the second prong of Hammarley. In fact he concedes there are other individuals to whom he confessed and through whom he could prove the falsity of his confessions.

This concession destroys any possibility that he can meet the third and fourth Hammarley hurdles: that the information he seeks is not available from a source less intrusive upon the privilege and that there is a reasonable possibility such evidence might result in his exoneration. Not only has he not met that burden he has proved the opposite: there are numerous nonprivileged sources of apparently fungible inconsistent statements by Sapp.” (Hallissy, supra, 200 Cal.App.3d at p. 1046.) 3. Our decision disapproving Hallissy In May 1990, before trial began in this case, this court decided Delaney v.

Superior Court (1990) 50 Cal.3d 785 [268 Cal.Rptr. 753, 789 P.2d 934] (Delaney), and addressed several issues pertaining to the newsperson’s shield law. Notably, Delaney adopted a different and less onerous test for a criminal defendant’s discovery of information covered by the shield law than the one set out in Hammarley, supra, 89 Cal.App.3d 388, and reiterated by the Court of Appeal in Hallissy, supra, 200 Cal.App.3d at page 1046, when discussing the motion in defendant’s case.

Delaney states: “First, the burden is on the criminal defendant to make the required showing. [Citation.] Second, the defendant’s showing need not be detailed or specific, but it must rest on more than mere speculation. Third, the defendant need not show a reasonable possibility the information will lead to his exoneration.

He need show only a reasonable possibility the information will materially assist his defense.” (Delaney, supra, 50 Cal.3d at p. 809, second italics omitted.) In addition, Delaney rejected “a universal and inflexible alternative-source requirement” in criminal cases, and specifically disapproved contrary suggestions in Hammarley, supra, 89 Cal.App.3d at page 399, and Hallissy, supra, 200 Cal.App.3d at page 1046, on that point. (Delaney, supra, 50 Cal.3d at p. 812; id. at p. 813 & fn. 29.) Finally, in discussing the interests to be protected by the shield law, Delaney observed that some circumstances “may, as a practical matter, render moot the need to avoid disclosure,” and gave as an example a situation in which “the criminal defendant seeking disclosure is himself the source of the information, [when] it cannot be seriously argued the source (the defendant) will feel that his confidence has been breached.” (Delaney, supra, 50 Cal.3d at p. 810, italics added.) In a footnote, Delaney made a specific reference to this case, stating: “Such was the situation in Hallissy v.

Superior Court, supra, 200 Cal.App.3d 1038. A reporter published a story based on an interview with a criminal defendant that led to additional charges being filed against him. He sought to question the reporter to show the published statements were inconsistent with other statements the defendant had made to the reporter. The trial court correctly noted that ‘The source of the information is the very person who is seeking full disclosure.’ (Id. at p. 1042.) The Court of Appeal, however, paid no heed to this circumstance in reversing the order of contempt against the reporter.

As explained above, such circumstance is significant.

We disapprove Hallissy to the extent it did not consider the fact that the party seeking disclosure was the source of the unpublished information.” (Delaney, supra, at pp. 810-811, fn. 27.) Thus, this court’s decision in Delaney, supra, 50 Cal.3d 785, rejected the Court of Appeal’s analysis in Hallissy, supra, 200 Cal.App.3d 1038, for three key reasons: First, Hallissy concluded that defendant had to but failed to show the reporter’s unpublished notes would lead to his exoneration (id. at p. 1046), whereas Delaney held a defendant need only show “a reasonable possibility the information will materially assist his defense” (Delaney, at p. 809, italics omitted).

Second, Hallissy determined that defendant failed to show “that the information he seeks is not available from a source less intrusive upon the privilege” (Hallissy, at p. 1046), but Delaney held there was no universal and inflexible alternative source requirement (Delaney, at p. 812). Third, Hallissy ignored the fact that defendant was the source of the information he sought, whereas Delaney held that this circumstance “may, as a practical matter, render moot the need to avoid disclosure.” (Delaney, at p. 810.) 4.

Defendant’s contentions Defendant asserts here that because of the Court of Appeal’s decision in Hallissy, supra, 200 Cal.App.3d 1038, which Delaney, supra, 50 Cal.3d 785, disapproved on three points, he was denied access to the unpublished statements he had made to Contra Costa Times reporter Erin Hallissy. He further asserts that those statements likely would have contradicted statements he made to the investigating officers, and thus the unpublished statements, if introduced at his capital trial, would have aided his defense that he was a chronic false confessor.

Defendant acknowledges that the law of the case doctrine generally requires that an interlocutory appellate decision “must be adhered to throughout” the future progress of the case it decided (People v. Stanley (1995) 10 Cal.4th 764, 786 [42 Cal.Rptr.2d 543, 897 P.2d 481]), and that this rule, if applied here, would mean that the Hallissy court’s

interpretation of the newsperson’s shield law would be binding on defendant’s automatic appeal. He points out, however, that under an exception to the law of the case doctrine, an interlocutory decision in a case is not binding during later proceedings in that case if before those proceedings a decision in another case has “altered or clarified” controlling rules of law. (People v. Stanley, supra, at p. 787.) This, he asserts, is the situation here. Before defendant’s capital trial, Delaney, supra, 50 Cal.3d 785, “altered or clarified” controlling rules of law with respect to the newsperson’s shield law.

Even assuming that defendant is correct in his assertion that the situation here falls within an exception to the law of the case doctrine, his claim must fail, as we explain below. We filed our decision in Delaney, supra, 50 Cal.3d 785, in May 1990. Defendant’s capital trial did not begin until January 1991. Yet in the intervening seven months after Delaney altered or clarified the rules governing a criminal defendant’s access to unpublished reporter’s notes, defendant never sought to subpoena or otherwise obtain the unpublished notes of his 1986 interview with Erin Hallissy.

As defendant concedes, after July 6, 1988, when the Court of Appeal’s writ of mandate issued vacating the magistrate’s contempt order, “[n]o further reference to the Hallissy matter appears in the record.” Accordingly, defendant cannot now complain that the trial court refused to apply the Delaney standard in his case.

Moreover, even if we assume that defendant was erroneously denied access to his own statements made to reporter Hallissy, and that those statements substantially contradicted his confessions to law enforcement officers regarding the murders of victims Weber, Duarte, and Abono, defendant would not be entitled to relief.

Because of the other strong evidence linking defendant to the killings of Weber, Duarte, and Abono, we are persuaded that the jury’s consideration of defendant’s self-serving denials to a newspaper reporter would not have altered the outcome of any of the murder charges or of the multiple-murder special-circumstance allegation. (See People v.

Cooper (1991) 53 Cal.3d 771, 820 [281 Cal.Rptr. 90, 809 P.2d 865].) With respect to the financial gain special circumstances, which substantially relied on defendant’s admissions to the investigating officers, defendant arguably could establish prejudice if the reporter’s unpublished notes of defendant’s statements to the reporter showed that he had denied killing Weber and Duarte for money.

In that situation the jury, faced with such contradictory statements by defendant about the role financial gain played in motivating his killings of Weber and Duarte, might have rejected one or both of the financial-gain special-circumstance allegations. But the record here is devoid of any suggestion that the reporter’s unpublished notes included any denial by defendant that he committed these two murders for financial gain.

On these facts, defendant has not shown that depriving him of access to Hallissy’s unpublished interview notes prejudiced his defense to the two financial-gain special-circumstance allegations. (Ibid.) IV. GUILT PHASE ISSUES A. Introduction of Certain Statements by Defendant At trial, the prosecution introduced evidence of defendant’s confessions to law enforcement that he had murdered Weber, Duarte, and Abono. The prosecution also played for the jury recordings of the interrogation sessions during which defendant confessed, and it provided the jury with transcripts of the recordings.

Both the tapes and the transcripts were “redacted” versions of the interrogation sessions, as the trial court excluded evidence of some parts of those sessions. Defendant complains here of 11 statements that were not ordered omitted and consequently were included in the materials given to the jury. He seeks reversal on the ground that the introduction of those 11 statements violated the Fifth, Eighth, and Fourteenth Amendments to the federal Constitution, asserting the statements indicated to the jury that defendant had committed other uncharged murders. We reject the conten
