    PEOPLE v. FLINNER
    S123813
    Opinion of the Court by Kruger, J.
    A jury convicted defendant Michael William Flinner of the
    first degree murder of Tamra Keck and found true financial-gain
    and lying-in-wait special-circumstance allegations. (Pen. Code,
    § 187, subd. (a);
    id., § 190.2, subd.
    (a)(1), (15).) The jury also
    convicted Flinner of conspiracy to commit murder and grand
    theft (id., § 182, subd. (a)(1);
    id., § 187, subd.
    (a);
    id., § 487, subd.
    (a)); mingling a harmful substance with food or drink (id., § 347,
    subd. (a)); and solicitation to commit murder (id., § 653f, subd.
    (b)). The jury could not reach a verdict on a second count of
    solicitation to commit murder. Following a penalty phase trial,
    the jury returned a death verdict and the trial court entered a
    judgment of death. The court also sentenced Flinner to an
    indeterminate term of 25 years to life for the conspiracy
    conviction, a determinate term of four years for the mingling a
    harmful substance with food or drink conviction, and a
    determinate term of six years for the solicitation to commit
    murder conviction.         The court imposed but stayed the
    indeterminate and determinate sentences pending the
    resolution and execution of the death judgment.
    This appeal is automatic. (Cal. Const., art. VI, § 11, subd.
    (a); Pen. Code, § 1239, subd. (b).) We affirm the judgment.

    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    I. FACTUAL BACKGROUND
    A. Guilt Phase
    The trial evidence showed that on June 11, 2000, Flinner
    called his fiancée, Tamra Keck, while she was out shopping. He
    directed her to meet his former employee, Haron Ontiveros (also
    known as Juan de la Torre), at a local gas station so that she
    could help jump start Ontiveros’s car. Keck picked Ontiveros up
    from the gas station and drove to a nearby cul-de-sac where
    Ontiveros’s car was parked. As Keck was propping the hood of
    her car open, Ontiveros approached her from behind and shot
    her in the back of the head, killing her.
    1. Prosecution Evidence
    Flinner met Keck in 1999. At the time, Keck was 18 years
    old and had just started her senior year of high school. Flinner
    was 31 or 32 years old and was operating a landscaping business
    after being paroled from prison earlier that year. Flinner and
    Keck developed a romantic relationship. Keck moved into
    Flinner’s apartment in Alpine, California, and the two made
    plans to marry.
    On December 29, 1999, Flinner and Keck met with an
    Allstate Insurance agent and applied for a $500,000 term life
    insurance policy for Keck, naming Flinner as the primary
    beneficiary. At the meeting, Flinner introduced Keck as his
    fiancée and represented that she was an employee of his
    landscaping business with an annual income of $30,000 per
    year. Flinner explained to the Allstate agent that they were
    taking out the life insurance policy because Keck was an
    important part of his landscaping business and that he would
    suffer financially were something to happen to her. This
    explanation was false. Keck was not, in fact, a regular employee
    2
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    of Flinner’s business; Keck occasionally purchased office
    supplies for Flinner, who then reimbursed her, but those
    payments were irregular and relatively small. Although Flinner
    did not provide verification of Keck’s employment or salary, the
    agent issued the insurance policy. Flinner and Keck paid for the
    first insurance premium payment that day, and Flinner paid for
    the next two premium payments in March and April 2000.
    The prosecution sought to show that Flinner’s business
    was suffering financially in the months leading up to the murder
    and that he accumulated an increasing amount of debt. After
    Keck’s death, Flinner attempted to collect on the insurance
    policy, attempted to make large purchases on credit with the
    promise of payment out of his forthcoming insurance proceeds,
    and continued even in custody to tell fellow inmates that he
    expected to receive a substantial payout plus interest from the
    life insurance policy.
    The prosecution also presented evidence that Flinner’s
    relationship with Keck was strained. Flinner took another
    teenage girl, Tiffany Faye, out for meals several times and told
    her that although Keck thought they were going to get married,
    he could get rid of Keck and date Faye. In December 1999, while
    Faye was visiting Flinner and Keck at their apartment, Flinner
    proposed a “threesome,” which prompted Faye to break off her
    relationship with Flinner. Various witnesses testified that
    Flinner treated Keck poorly, said Keck was just after his money,
    and referred to her by derogatory names. Two days before the
    murder, Keck called her mother, crying, to report the wedding
    was going to be postponed.
    Around the time Flinner and Keck took out the life
    insurance policy, Flinner began asking associates what it would
    3
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    cost to have someone killed and whether they would kill
    someone on his behalf. Robert Johnston, one of Flinner’s
    employees, testified that sometime between December 1999 and
    January 2000 Flinner asked whether Johnston would kill
    somebody for him. Charles Cahoon, who worked briefly for
    Flinner, testified that in January 2000, Flinner asked Cahoon
    how much it would cost to have somebody killed and whether
    $10,000 would be enough. When Cahoon asked Flinner what he
    was talking about, Flinner said that he had gotten Keck insured
    for $1,000,000. Juan Morales testified that in April 2000, while
    paying Flinner for a car Morales had bought from him, Flinner
    asked Morales if he knew where to get a gun.
    A few days before the murder, Flinner obtained the car
    that codefendant Haron Ontiveros, one of Flinner’s landscaping
    employees, would use on the day of the murder.1 Flinner visited
    an auto dealership that he had done business with before and
    signed a borrower agreement for a small white Nissan NX car.
    Amir Bahador, an employee at the auto dealership, testified that
    when Flinner came to pick up the Nissan NX, he was
    accompanied by a “Hispanic gentleman, kind of short, kind of
    stocky,” though Bahador could not say for sure that it was
    Ontiveros. Flinner told Bahador that he was getting the car for
    his employee, the man who was with him at the dealership.
    1
    Ontiveros was tried jointly with Flinner before a separate
    jury, which found Ontiveros guilty of first degree murder and
    conspiracy to commit murder and found true the lying-in-wait
    and financial-gain special circumstances. At the penalty phase,
    Ontiveros’s jury returned a verdict of life in prison without the
    possibility of parole, and the court sentenced Ontiveros to life in
    prison without the possibility of parole for the murder conviction
    and a concurrent term of 25 years to life for the conspiracy
    conviction.
    4
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    After the murder, Flinner also gave Ontiveros a forged check for
    $7,000 in payment for his role.
    On the morning of the murder, at about 10:45 a.m., video
    surveillance showed Flinner driving his white Ford pickup to
    the Ultramar gas station in Alpine. Flinner was also placed at
    that location through his cell phone records and the testimony
    of Phillip Finch, who drove by Flinner while he was pulled over
    on the road near the gas station to make a call. The clerk at a
    nearby Shell station testified that around 10:30 a.m. Flinner
    purchased gas and milk and asked the clerk to hurry ringing up
    the purchase because he “was late to meet his friend down the
    street.”
    At about the same time, video surveillance showed the
    white Nissan NX driving into the Ultramar gas station. Shortly
    thereafter, video showed both Flinner’s Ford pickup and
    Ontiveros’s Nissan NX leaving the Ultramar station and
    heading toward a cul-de-sac down the street. Flinner later
    admitted to detectives that he entered the cul-de-sac sometime
    between 10:00 a.m. and 11:00 a.m. on the morning of the
    murder. Suzanne Scanlan, who volunteered at a veterans’
    organization that had a view of the cul-de-sac, testified that in
    this timeframe she saw two white cars parked next to each other
    in the cul-de-sac. Video footage picked up the two white cars
    exiting the cul-de-sac road about 15 minutes after they entered.
    Flinner arrived at his parents’ house at about 11:30 a.m.
    on the day of the murder. Shortly thereafter, at around
    11:45 a.m., Keck and Flinner left Flinner’s parents’ house
    separately — Flinner to go shopping and to a car wash with his
    son and Keck to go to Walmart and Vons. Walmart’s video
    surveillance showed Keck entering and shopping in the store.
    5
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    While Keck was at Walmart, phone records show she received
    two calls from Flinner, at 12:08 p.m. and 12:15 p.m., and Flinner
    confirmed in a police interview that he called Keck while she
    was at Walmart. Video then showed Keck leaving the Walmart
    and, instead of driving to Vons, entering the Ultramar gas
    station.
    In the meantime, surveillance video showed the white
    Nissan NX driving back into the cul-de-sac at 12:02 p.m. A man
    left the cul-de-sac by foot at 12:08 p.m. and headed toward the
    Ultramar gas station, where he arrived and waited in front of
    the station. At 12:32 p.m., video showed Keck’s white Mustang
    coming into the Ultramar station and pulling up to where the
    man was waiting (although he was no longer visible in the
    surveillance video), and it then showed the Mustang leaving the
    station and heading toward the cul-de-sac. About three minutes
    after the Mustang entered the cul-de-sac, video showed the
    white Nissan NX speeding out of it.2
    Shortly after the murder, a motorist discovered Keck’s
    body and called the police. Keck’s body was found lying in front
    of her car. The car’s engine was running, the hood was ajar and
    the passenger side door open. Keck had been shot once in the
    back of the head. This and other circumstantial evidence
    indicated that, once she had parked in the cul-de-sac, Keck left
    her car running and exited the vehicle. While she was opening

    We consider the details of the evidence concerning the
    events in the cul-de-sac during these three minutes in further
    depth below, in connection with Flinner’s claim that insufficient
    evidence supports the lying-in-wait special-circumstance
    finding.
    6
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    the hood of her car, she was shot in the head from behind. She
    died within a minute of being shot.
    Flinner attempted to cast the responsibility for Keck’s
    murder on others. In the days before the murder, Flinner had
    told two sheriff’s deputies that one of his landscaping customers
    was “after him” and had tried to run him off the road, though he
    dismissed the deputies’ suggestion that Flinner file a police
    report. During an interview with lead detective Rick Scully on
    the night of the murder, Flinner denied being near the cul-de-
    sac that day and said he had never been to the cul-de-sac. He
    again brought up the disgruntled customer and said that one of
    the customer’s associates had recently threatened his life and
    initiated a physical altercation with him.
    Later that night, the police searched Flinner and Keck’s
    apartment. During the search, Detective Scully told Flinner
    that in his experience people who are found in isolated areas, as
    Keck was, are usually there for a drug deal or to meet a love
    interest. At the time, Flinner rejected this theory of Keck’s
    death and police found no evidence suggesting Keck was using
    drugs. But days later, Flinner contacted police to say he and his
    mother had found drugs and syringes while going through
    Keck’s possessions, and they turned them over to Detective
    Scully. Within a week of the shooting, Flinner also reported he
    had received threatening phone calls from a Hispanic man with
    whom he had been in an altercation a decade before.
    Later in the investigation, Flinner attempted to frame or
    cast blame for Keck’s murder on various employees and business
    associates. Flinner invited employee Martin Baker to dinner at
    his house about a month after the murder and spiked Baker’s
    chili with Xanax. While Baker was passed out on Flinner’s
    7
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    couch, Flinner called his friend Gilberto Lopez and asked Lopez
    to call Flinner’s home number from a pay phone. Flinner then
    called the police and said that he had just received a call from a
    woman who claimed Baker had confessed to Keck’s murder and
    that Baker was currently asleep on his couch.
    Next, Flinner apparently tried to frame employee Charles
    Cahoon by planting a sock that contained bullets matching the
    bullet that killed Keck in Cahoon’s car. DNA on the sock
    matched Keck’s and Flinner’s, but not Cahoon’s. An anonymous
    letter accusing Cahoon of murder was also placed on a police car.
    Flinner also told detectives that his friend and business
    associate Rick Host said on his deathbed that Keck was killed
    due to her knowledge of a casino software scheme Host was
    involved with that also involved the North Korean government
    and mobsters in the United States.
    Finally, while in custody, Flinner claimed that his
    codefendant Ontiveros killed Keck after having an affair with
    her and that Ontiveros had put out a contract on Flinner’s life.
    Flinner also attempted to make it look like he was being
    targeted, planting bullets with his and Keck’s names on them
    on his parents’ property.
    Flinner also made several attempts to derail his trial.
    Flinner attempted to taint the witnesses in his case by mailing
    them letters containing information deemed inadmissible by the
    trial court so that the witnesses’ testimony would be rendered
    suspect and impeachable. Flinner asked a fellow jail inmate,
    Gregory Sherman, to use his library privileges to look up the
    addresses of witnesses, detectives, the prosecutor, and the trial
    judge in his case. Flinner told Sherman that he intended to
    sabotage his trial by sending witnesses letters with confidential
    8
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    information that would preclude them from testifying. He
    indicated that he would make it look like his former attorney or
    a detective in the case sent the letters and would then have an
    associate “take out” the fall guy. Flinner then sent these names
    and addresses to a former girlfriend, Catherine McLarnan,
    along with a cover letter that he directed her to send to all of the
    witnesses. He instructed her to use the address of his former
    defense attorney as the return address for the letters.
    McLarnan instead turned the information over to a defense
    investigator.
    Flinner had a backup plan to sabotage his trial: He told
    Sherman that he planned to ensure that only property owners
    with unique names were impaneled as jurors so that he could
    easily look up their addresses through property records searches
    and send them similar letters with inadmissible evidence.
    Flinner said he would frame the prosecutor for sending this set
    of letters by using the prosecutor’s address as the return
    address.
    Flinner also made various threats intended to obstruct the
    prosecution of his case. He asked fellow inmate James
    Theodorelos and another inmate to kill his codefendant
    Ontiveros. When these inmates began cooperating with the
    prosecution, Flinner tried to intimidate them or pay them off.
    Finally, Flinner tried to intimidate the prosecutor by sending
    letters conveying threats against the prosecutor to Flinner’s
    family and other inmates, knowing the letters were being
    photocopied and read by the authorities.
    Flinner made a number of statements after Keck’s death
    that suggested he was complicit in her murder. Robert Pittman,
    a former employee of Flinner, testified that the morning after
    9
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    the murder Flinner called him and said that Keck had been shot
    in the back of the head, even though this information was not
    public at the time and the pathologist had not yet determined
    whether Keck was shot in the face or in the back of the head.
    Flinner described other details about the crime at times when
    they were not publicly known, such as that Keck’s car was
    running when found.
    A few days after the murder, Flinner went out to dinner
    and drinks with his friend Gilberto Lopez and Lopez’s girlfriend
    Marie Locke. According to Lopez, Flinner got “tipsy” at the meal
    and became upset about Keck’s death, stating either “I shouldn’t
    have killed her” or “I should not have had her killed.” On
    another occasion after Keck’s murder, and after Flinner had
    taken several sleeping pills, Flinner again said to Lopez, “I
    shouldn’t have killed her.” In custody, Flinner told fellow
    inmate Theodorelos that Keck’s murder stemmed from an ill-
    fated business transaction with “some overseas Asians.” But
    Flinner subsequently told Theodorelos that he was sure to make
    credit card purchases at the time of Keck’s murder to create an
    alibi for himself and that he had bullets planted on his parents’
    property and an anonymous note accusing Cahoon of killing
    Keck left on a police car.
    2. Defense Evidence
    The defense argument was that Flinner had nothing to do
    with Keck’s murder. Flinner presented evidence that he was
    loving and kind toward Keck. He also put on evidence intended
    to bolster several exculpatory theories Flinner had raised during
    the investigation and before trial. According to Donald Landon,
    a business partner of Flinner’s friend Rick Host, Host was at the
    same Walmart as Keck the morning she was killed. Landon also
    10
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    testified about Host’s gambling ventures. Flinner’s father
    testified that Flinner had received threatening phone calls after
    the murder and that Flinner’s parents had received anonymous
    calls as well. The defense also presented evidence that there
    was a tunnel near the crime scene big enough for an adult to
    pass through that people used to pass under the nearby
    highway.
    Flinner sought to discredit some of the People’s evidence.
    A forensic accountant testified that while the prosecution had
    calculated Flinner’s debt at the time of the murder to be
    $194,000, the accountant calculated it to be about $94,000. A
    custodian of records for a local news channel produced
    recordings of news broadcasts about the murder and testified
    that the channel publicized that Keck was shot in the head the
    morning after the murder, which could have explained how
    Flinner was able to report this information to Pittman on the
    same day; on cross-examination, however, the witness clarified
    that at no time did the broadcasts say that Keck was shot in the
    back of the head, as Pittman had testified Flinner told him.
    Prison inmate James Baggett testified that inmate Theodorelos
    said he intended to fabricate the statements from Flinner about
    the murder. Flinner’s DNA expert challenged the prosecution
    expert’s conclusion that DNA found on the sock in Cahoon’s car
    belonged to Flinner. A defense investigator testified that
    Martin Baker, one of the employees Flinner had tried to frame
    for Keck’s murder, had been prescribed Xanax after receiving
    treatment at the county mental health hospital, and defense
    counsel elicited Baker’s testimony on cross-examination that at
    the time of trial Baker was living in an assisted care facility and
    taking several antipsychotic medications.             A defense
    investigator testified that after reviewing of the gas station
    11
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    surveillance tapes, he was unable to identify the driver of the
    white Ford pickup truck.
    B. Penalty Phase
    The prosecution introduced the testimony of Keck’s family
    members, who described her early life and the impact that losing
    Keck had on them. The prosecution also introduced the
    testimony of four women, including Flinner’s former wife, who
    described being sexually assaulted by Flinner after he drugged
    them, or other forms of physical and emotional abuse. Finally,
    the prosecution introduced evidence of Flinner’s prior felony
    convictions for forgery, possession of stolen property, rape by a
    foreign object, three counts of grand theft, and failure to appear
    while on bail.
    The defense called Flinner’s mother and father, who
    testified about Flinner’s troubled childhood, including
    hyperactivity, various head injuries, behavioral problems, and
    psychiatric hospital admissions. The defense introduced expert
    psychiatric evidence that Flinner suffered brain dysfunction
    from early childhood, possibly exacerbated by the use of illegal
    drugs and head injuries, which contributed to his criminal and
    antisocial behaviors. Prison officers testified that Flinner had
    previously attempted suicide after he was returned to prison. A
    correctional consultant testified about the security measures
    that would be in place if Flinner was sentenced to life without
    the possibility of parole. Flinner’s friend and a fellow inmate
    testified about Flinner’s efforts to help them during previous
    emergency situations. Flinner’s son testified that he loved his
    father, who had kept in touch since he was arrested.

    II. DISCUSSION
    A. Pretrial Issues
    1. Pretrial Detention
    Flinner raises four claims of error stemming from
    Flinner’s pretrial relocation from a downtown San Diego jail
    facility to a more remote jail facility in Vista, which is in the
    northern part of San Diego County. We conclude these claims
    lack merit.
    a. Background
    Flinner was detained in San Diego County facilities while
    awaiting trial. In January 2002, defense counsel requested that
    Flinner remain in the downtown jail and not be moved to the jail
    in Vista. The court entered a “request[],” but not an order, to
    that effect.
    As explained in greater detail above, while in jail Flinner
    sought to disrupt his upcoming trial. With the help of Gregory
    Sherman, a fellow jail inmate with library privileges, Flinner
    obtained personal information about the prosecutor and trial
    judge, including their home addresses. Sherman later gave his
    account of their activities to the San Diego County District
    Attorney’s Office. The information was passed to the San Diego
    County Sheriff’s Department, as well as the trial judge, Allan J.
    Preckel.
    At a January 17, 2003, ex parte hearing, the prosecutor
    discussed this information with Judge Preckel. Immediately
    afterward, Judge Preckel held a security meeting with sheriff’s
    department personnel, the supervising judge of the courthouse,
    and the prosecutor, but not defense counsel. The supervising
    judge requested Flinner be moved to a more secure housing unit
    to prevent him from gathering further information and
    13
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    attempting to manipulate events outside the jail. The assistant
    sheriff proposed the Vista facility as having the most secure cells
    but noted that if Flinner were moved to Vista the court would be
    “hearing from the defense attorney.” Judge Preckel agreed
    Flinner’s attorneys would be displeased, but the supervising
    judge indicated he approved of the move. No order was issued.
    Later in January 2003, the sheriff transferred Flinner to
    Vista and placed him in administrative segregation, restricting
    his visitation and telephone privileges. At a conference with all
    parties and counsel on February 28, 2003, the trial court
    summarized Flinner’s custodial status as related by the sheriff’s
    office: Flinner was housed in an isolation cell and allowed no
    contact with other inmates; he was permitted three 20-minute
    telephone calls per week to Sandra Resnick, one of his two
    attorneys, and 45-minute personal visits with Resnick or John
    Mitchell, his other attorney, if they gave a day’s notice. The
    court added that Flinner was permitted visits with the defense
    investigator. The court emphasized that it had not ordered
    these restrictions and was generally not inclined to interfere
    with the sheriff’s decisions on jail operations. Attorney Resnick
    complained that the distance to Vista and the limits on
    communications would slow down the defense team’s
    preparation for trial; in particular, Resnick expressed
    frustration at the inability of defense team members other than
    herself to arrange telephone conversations with Flinner. In
    response, the court stated it was willing to consider making
    orders to allow increased contact “as they are presented to me.”
    After the February 28 conference, the trial court issued an
    order providing information Sherman had supplied to Flinner’s
    attorneys but prohibiting them from revealing the information
    to Flinner or other members of the defense team. On March 11,
    14
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    defense counsel, in an ex parte hearing, complained about the
    restrictions on their communication with and access to Flinner.3
    Counsel’s primary concern was that their relationship with
    Flinner would be disrupted by their inability to tell him about
    Sherman’s disclosure. Attorney Mitchell stated that the
    restriction “requires me to lie to my client, at least by omission
    and possibly by commission.” Attorney Resnick explained that
    Flinner had been asking why he had been moved to Vista and
    had his telephone privileges restricted. By not telling him the
    reasons these security measures had been taken, Resnick
    “almost began to feel as though [she] was lying to [her] client by
    omission.”
    Attorney Mitchell also elaborated on the difficulties with
    the Vista location and the telephone restrictions. Driving to and
    from Vista meant each visit took half a day. In order to prepare
    for trial and maintain their relationship with a sometimes
    difficult client, Mitchell and Resnick each tried to visit Flinner
    once a week, while their investigator did so twice a week. The
    telephone restrictions prevented Mitchell or the investigator
    from talking to Flinner by phone. When Mitchell visited
    Flinner, jail officers searched his briefcase.
    In response, the trial court repeated that it was not
    inclined to second-guess the sheriff’s department as to the
    appropriate housing for Flinner or, at least “here and now,” as
    to telephone privileges. Attorney Mitchell suggested that, given
    3
    In the interim, the trial court had, at defense request,
    issued three orders allowing increased contact between Flinner
    and the defense team: Counsel and the investigator were given
    access to Flinner in the holding area before and after court
    appearances, and two defense trial consultants were permitted
    contact visits with him.
    15
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    the security measures in place, the court could relax the
    prohibition on counsel telling Flinner and their investigator
    about the information Sherman had provided. The court found
    Mitchell’s suggestion “well taken” and proposed discussing it
    further at an upcoming conference with all counsel.
    On March 14, 2003, after an additional brief ex parte with
    Flinner’s attorneys, the trial court conferred with counsel for all
    parties, with neither defendant present. The court explained
    that with Flinner now securely housed at Vista and a mail cover
    and telephone restrictions in place, the court tentatively
    planned to lift its previous prohibition on defense counsel
    discussing Sherman’s disclosure with Flinner and members of
    the defense team, with the proviso that the written materials
    would still not be provided to Flinner. The court noted that its
    previous order would remain in place for a reasonable period so
    that Sherman could be provided whatever additional security
    was deemed necessary.
    Asked for comment, Attorney Mitchell said that the court’s
    proposal to lift the prohibition on talking to Flinner about
    Sherman’s disclosure “makes good sense.” He expressed the
    hope that this “resolution” would allow defense counsel to
    “finesse” their previous concealments from their client and
    “move on in terms of the attorney/client relationship. We’re
    going to be together for a while in this matter.” As to Flinner’s
    housing and telephone restrictions, Mitchell “assume[d]” that
    the defense was “stuck with that,” that as the court had said
    earlier, “You run the courtroom and they run the jail, and you’re
    not going to get involved unless it fouls up your courtroom.”
    Mitchell went on to observe that a time might come when the
    defense needed greater access to Flinner, for example to have an
    16
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    expert consult by telephone, “but we may be able to do that on a
    case by case basis, so I’ll kind of leave that aside.”
    The prosecutor raised no objection to the court’s tentative
    order but requested a few days to alert Sherman’s current
    confinement facility and allow them to take necessary security
    measures. The court set a further conference for March 19, five
    days later. At that hearing, the prosecutor confirmed necessary
    measures had been taken, and the court issued the order.
    b. Discussion
    i. Interference with Attorney-Client
    Relationship
    Flinner contends that the trial court, prosecutor, and
    sheriff interfered with his attorney-client relationship by
    moving him to the Vista detention facility and restricting his
    telephone and visiting privileges, in violation of his
    constitutional rights to due process and the assistance of
    counsel. Flinner maintains the imposition of these restrictions
    “greatly interfered with the preparation of [his] defense by
    requiring a time-consuming 82 mile round trip for each visit,
    barring visits from members of the defense team other than
    appointed counsel, and sharply limiting the time counsel had to
    confer with their client.” The trial judge, Flinner argues, also
    violated his constitutional rights by permitting the sheriff to
    impose these restrictions without a contested evidentiary
    hearing to determine the credibility of Sherman’s disclosure,
    and by ordering defense counsel to “lie” to their client by
    concealing the disclosure from him.
    At the threshold, we agree with the Attorney General that
    these claims were forfeited by Flinner’s failure to raise them
    below.     Although defense counsel complained of the
    17
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    inconvenience of visiting Flinner at the Vista facility and of his
    limited telephone privileges, counsel never asserted these
    conditions infringed on Flinner’s right to counsel or, for that
    matter, any other legal right. Nor did Flinner or his attorneys
    demand an evidentiary hearing on whether he could be kept in
    administrative segregation based on Sherman’s report.4 Having
    made no objection or request on these grounds, Flinner failed to
    preserve his due process and right to counsel claims.
    Nor do the claims have merit. Visiting Flinner at the Vista
    facility was undoubtedly inconvenient for the defense team, but
    nothing in the record suggests Flinner’s housing or telephone
    restrictions prevented counsel from effectively communicating
    with Flinner in order to prepare for trial. The trial court, at
    defense request, permitted increased communication with
    members of the defense team (see fn. 3, ante) and the court said
    nothing to preclude further accommodations as needed “on a
    case by case basis,” as Attorney Mitchell put it. Trial counsel’s
    4
    Attorney Mitchell initially stated he was “concerned by the
    acceptance of what this individual [Sherman] said as being the
    truth.” But he never asked for an evidentiary hearing to
    determine that point. After Judge Preckel explained that he
    was inclined to substantially credit Sherman’s information —
    because the informant had “provided a lot of detail,” much of
    which rang true, and he “knows too much to simply be creating
    this out of whole cloth” — Mitchell did not raise the point again.
    At oral argument, defense counsel asserted that further
    defense complaints or requests would have been futile because
    the trial judge had disavowed any authority over jail
    confinement conditions. The record does not support this
    assertion: Though the judge indicated he would generally defer
    to the sheriff’s department, he also agreed to make changes after
    defense complaints, and did not close the door to additional
    accommodations.
    18
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    principal concern, the court’s order prohibiting them from
    telling Flinner about Sherman’s report, was in place less than
    three weeks before being resolved by the trial court’s revised
    order on March 19, 2003. At the March 14 hearing, Mitchell
    expressed the hope this would allow any damage to the attorney-
    client relationship to be repaired over the long pretrial and trial
    period to come, and Flinner points to nothing in the record
    suggesting it did not.
    Had Flinner requested a hearing on his placement in
    administrative segregation, and done so in an appropriate
    forum, he might have been entitled to one. (See In re
    Davis (1979) 
    25 Cal. 3d 384
    , 390–391 [where state prison
    regulations set out “specific circumstances under which
    administrative segregation may be imposed,” “ ‘the inmate has
    an interest, conferred by statewide regulation and protected by
    due process, in not being confined in maximum security
    segregation unless he is found, for clearly documented reasons,
    to come within the standard set by the rules’ ”].) But without
    any such request at the time, and with no indication in the
    record that Flinner’s housing placement deprived him of any
    trial right or prejudiced the result of his trial, he is not entitled
    to a reversal on this ground.
    ii. Violation of Right to be Present at All
    Critical Stages of Proceedings
    Flinner next asserts that the trial court violated his right
    to be present all critical stages of proceedings, pointing to the ex
    parte discussions with jail personnel and the in camera
    discussions with the attorneys. Contrary to the Attorney
    General’s argument, Flinner had no effective opportunity to
    object to proceedings at which he was not present, and therefore
    did not forfeit his due process claim. The claim fails on the
    19
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    merits, however, because none of these pretrial proceedings,
    which concerned only the circumstances of Flinner’s
    confinement in jail, were critical to the determination of guilt or
    penalty.
    A defendant has the constitutional right to be personally
    present in court “where necessary to protect the defendant’s
    opportunity for effective cross-examination, or to allow him to
    participate at a critical stage and enhance the fairness of the
    proceeding.” (People v. Carasi (2008) 
    44 Cal. 4th 1263
    , 1299.) It
    does not extend to “in camera discussions on matters bearing no
    reasonable, substantial relation to the defense of the charge.”
    (Ibid.) And while ex parte proceedings are generally disfavored,
    “the trial court retains discretion to conduct in camera, ex parte
    proceedings to protect an overriding interest that favors
    confidentiality.” (Ibid.) The same standard for requiring the
    defendant’s personal presence applies under California law, and
    to prevail on such a claim under federal or state law the
    defendant bears the burden of showing “that his absence
    prejudiced his case or denied him a fair trial.” (People v.
    Bradford (1997) 
    15 Cal. 4th 1229
    , 1357; accord, People v.
    Blacksher (2011) 
    52 Cal. 4th 769
    , 799.)
    The ex parte proceedings in this case were occasioned by
    the revelations of a jailhouse informant, Sherman, that while in
    jail Flinner had been engaging in investigative activities aimed
    at disrupting his upcoming trial, including obtaining personal
    information about the prosecutor and trial judge. The trial court
    acted within its discretion in excluding Flinner, and initially his
    attorneys, from these proceedings until Flinner had been placed
    in a more secure housing unit where his communication with
    other inmates could be controlled. Most important, Flinner fails
    to demonstrate that his absence from the hearings on his
    20
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    housing and telephone privileges resulted in any actual
    prejudice to his defense. The ex parte hearings did not concern
    the conduct of the trial, but only pretrial security measures.
    And as observed above, despite the inconvenience caused by
    Flinner’s housing in Vista and the discomfort defense counsel
    felt about temporarily concealing Sherman’s disclosure from
    Flinner, the record gives no indication the defense team was
    ultimately prevented from effectively preparing for trial.
    iii. Prosecutorial Bias
    Flinner argues that the prosecutor was biased against him
    after the prosecutor learned of Flinner’s death threats against
    him. Flinner asserts that this bias is manifest in the decision to
    have Flinner transferred to the Vista jail, a decision for which,
    he asserts, the prosecutor was at least in part responsible.
    During a February 28, 2003, status conference, Defense
    Attorney Resnick told the court that a sheriff’s captain at the
    Vista facility said the security of Flinner’s confinement was
    being monitored by Deputy District Attorney Paul Morley, a
    division chief within the district attorney’s office. Based on that
    apparent involvement by the prosecutor’s office, Flinner asserts
    the trial prosecutor, Deputy District Attorney Rick Clabby,
    misrepresented his influence in assuring defense counsel, “I
    have absolutely no control over what the jail does.”
    Flinner forfeited this claim by failing to raise it below. Once
    the information provided by Sherman became available to
    defense counsel, any claim of prosecutorial bias could and
    should have been raised by a motion under Penal Code section
    1424 to disqualify Prosecutor Clabby for a claimed conflict of
    interest.  Counsel neither moved for disqualification nor
    asserted by any other means that Clabby harbored a
    21
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    disqualifying bias against their client. “Defendant’s failure to
    move to disqualify the district attorney in the trial court bars
    appellate review of the claim.” (People v. Maury (2003) 
    30 Cal. 4th 342
    , 438.)
    In any event, nothing in the record indicates that Flinner’s
    threats and insults aimed at Prosecutor Clabby created a bias
    that threatened the fairness of the proceedings. If the existence
    of threats were sufficient by itself to require disqualification, a
    disruptive scheme like Flinner’s could easily succeed. “[W]ere it
    possible for a defendant charged with serious crimes to
    disqualify the prosecutors trying the case from proceeding with
    the prosecution by threatening them, willful defendants would
    be handed a powerful weapon to disrupt the course of justice.”
    (Millsap v. Superior Court (1999) 
    70 Cal. App. 4th 196
    , 204.) The
    fact that the district attorney’s office was monitoring Flinner’s
    housing status and communications restrictions does not show
    that Clabby or any other member of the office acted improperly.
    Having learned from Sherman of Flinner’s plans to disrupt the
    trial, prosecutors had a legitimate interest in seeing that
    security measures were taken to prevent those plans from being
    executed.
    iv. Judicial Bias
    Flinner also argues Judge Preckel was biased after he was
    warned that Flinner had made a threat against him. Flinner
    infers bias from Judge Preckel’s “refus[al] to become involved in
    the unconstitutional restrictions the prosecutor and jailer had
    arranged, which improperly limited appellant’s access to his
    counsel.” Flinner argues it was therefore a due process violation
    for Judge Preckel to preside over his trial.
    22
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    The Attorney General argues this claim was forfeited by
    Flinner’s failure to move for Judge Preckel’s recusal. Flinner
    responds that his codefendant had already used a peremptory
    challenge (Code Civ. Proc., § 170.6) against the judge previously
    assigned. He concedes, however, that he could have requested
    recusal on grounds of bias (id., § 170.3, subd. (c)(1)), though he
    insists that would have “run the risk of further alienating”
    Judge Preckel. We agree with the Attorney General that if
    Flinner believed his threat had resulted in a bias against him
    on Judge Preckel’s part, he should have requested the judge
    recuse himself on that basis, either via the statutory procedure
    cited above or by a nonstatutory motion invoking Flinner’s right
    to due process. Instead, according to Attorney Mitchell, Flinner
    said he “feels he’s very comfortable” having Judge Preckel
    preside over his trial. Flinner cannot now ask for reversal on
    the basis of a claimed error he accepted without complaint
    below.5
    We also reject Flinner’s due process claim on its merits. A
    due process claim of this type requires a showing that “under
    the ‘extreme facts’ of the case, ‘the probability of actual bias rises
    to an unconstitutional level.’ ” (People v. Freeman (2010) 
    47 Cal. 4th 993
    , 1001.) Here there are no extreme facts and no
    probability of actual bias. Although Sherman had reported that
    Flinner raised the possibility of trying to kill his prosecutor and
    trial judge, there was no indication of imminent or severe
    5
    Flinner cites Arizona v. Fulminate (1991) 
    499 U.S. 279
    ,
    310, for the proposition that a structural defect like trial by a
    biased judge cannot be forfeited. The cited passage, however,
    states only that such structural defects are not subject to
    harmless error analysis; it says nothing about forfeiture.
    23
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    danger to Judge Preckel or anyone else. When first discussing
    Sherman’s information with the court, the prosecutor
    summarized the general threat level from Flinner as justifying
    “concern[]” and “aware[ness],” but did not “assess[] it much
    higher than that.” The record provides nothing to support
    Flinner’s assertion that the judge “likely feared” Flinner.
    As for the court’s deference to the sheriff’s department on
    details of Flinner’s housing and communications restrictions,
    such deference creates no inference of fear or bias. It is as
    consistent, or more so, with Judge Preckel’s repeated
    explanation that he respected the lines between judicial and law
    enforcement authority and expertise, and therefore would no
    more tell the sheriff how to run the jail than he would expect
    that officer to tell him how to run his courtroom.
    Nor, finally, did Judge Preckel display indifference to
    Flinner’s rights and interests. To the contrary, he showed a
    willingness to make and change orders as defense counsel
    convinced him was necessary for the attorney-client relationship
    and the defense team’s trial preparation. No probability of
    unconstitutional bias appears from the record.
    2. Denial of Flinner’s Severance Motions
    Flinner contends that he was denied the right to due
    process and a fair trial when the trial court declined to fully
    sever his case from that of his codefendant Ontiveros and
    instead empaneled two separate juries for a joint trial.
    “Penal Code section 1098 provides, in relevant part:
    ‘When two or more defendants are jointly charged with any
    public offense, whether felony or misdemeanor, they must be
    tried jointly, unless the court order[s] separate trials.’ ‘Joint
    trials are favored because they “promote [economy and]
    24
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    efficiency” and “ ‘serve the interests of justice by avoiding the
    scandal and inequity of inconsistent verdicts.’ ” ’ [Citation.]
    ‘When defendants are charged with having committed “common
    crimes involving common events and victims,” as here, the court
    is presented with a “ ‘classic case’ ” for a joint trial.’ [Citation.]
    We review a trial court’s denial of a severance motion for abuse
    of discretion, based on the facts at the time of the trial court’s
    ruling. [Citation.] ‘Even if a trial court abuses its discretion in
    failing to grant severance, reversal is required only upon a
    showing that, to a reasonable probability, the defendant would
    have received a more favorable result in a separate trial.’ ”
    (People v. Daveggio and Michaud (2018) 
    4 Cal. 5th 790
    , 819
    (Daveggio).) “Conversely, even if a trial court acted within its
    discretion in denying severance, ‘ “the reviewing court may
    nevertheless reverse a conviction where, because of the
    consolidation, a gross unfairness has occurred such as to deprive
    the defendant of a fair trial or due process of law.” ’ ” (People v.
    Thompson (2016) 
    1 Cal. 5th 1043
    , 1079 (Thompson).)
    “Defendants bear the burden of establishing that the trial was
    grossly unfair and denied them due process of law, and ‘a
    judgment will be reversed on this ground only if it is “reasonably
    probable that the jury was influenced [by the joinder] in its
    verdict of guilt.” ’ ” (Daveggio, at p. 821.)
    Before trial, the prosecution conceded that dual juries
    were appropriate but contended that the cases should proceed
    in a single trial. Flinner’s counsel moved to sever the cases
    completely on the ground that Flinner and Ontiveros intended
    to present antagonistic defenses. Flinner planned to argue that
    he was not involved at all in Keck’s killing, while Ontiveros
    intended to show that Flinner was the mastermind of the
    murder and manipulated Ontiveros into participating. As we
    25
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    have explained, “ ‘[m]utually antagonistic defenses are not
    prejudicial per se.’ ” 
    (Thompson, supra
    , 1 Cal.5th at p. 1081,
    quoting Zafiro v. United States (1993) 
    506 U.S. 534
    , 538.) In
    Daveggio, for example, we rejected an antagonistic-defense
    argument similar to the one raised here, in which one
    codefendant’s defense was that her codefendant “controlled her
    and was the instigator of their joint crimes.” 
    (Daveggio, supra
    ,
    4 Cal.5th at p. 819.)
    Flinner posits that the conflict here rises beyond mere
    antagonism; he claims that the two positions are “completely
    irreconcilable” because “[i]f the jury believed Ontiveros, it would
    have to convict [Flinner].” We have explained that “antagonistic
    defenses require severance only when ‘ “ ‘the conflict is so
    prejudicial that [the] defenses are irreconcilable, and the jury
    will unjustifiably infer that this conflict alone demonstrates that
    both are guilty.’ ” ’ [Citation.] ‘If the moving party’s guilt can be
    established by sufficient independent evidence, “it is not the
    conflict alone that demonstrates . . . guilt,” and severance is not
    required.’ ” 
    (Daveggio, supra
    , 4 Cal.5th at pp. 819–820.)
    We made the statements above in the context of a joint
    trial before a single jury. Whether antagonistic defenses ever
    require severance in the context of separately empaneled juries
    is unclear, but we need not decide that general question here.
    Flinner cannot show, in any event, that in this case the conflict
    between the two defenses alone established guilt, given the
    overwhelming independent evidence against him, including the
    video surveillance evidence showing Flinner and Ontiveros
    meeting shortly before the murder near the scene of the crime
    and the inculpatory statements Flinner made to Lopez. The
    nature of Flinner’s and Ontiveros’s defenses would not have
    compelled severance even in a single-jury trial. A fortiori, they
    26
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    did not do so in a dual-jury trial, where evidence properly
    admitted solely for or against one defendant could be excluded
    as to the other.6
    Nor did the existence of Ontiveros’s incriminating
    confession require the trial court to grant Flinner’s severance
    motion. The existence of an “ ‘ “incriminating confession” ’ ” is
    one of many “[f]actors that may bear on a trial court’s decision
    to order separate trials.” (People v. Gomez (2018) 
    6 Cal. 5th 243
    ,
    274.) But it is settled that a trial court may resolve admissibility
    problems posed by a codefendant’s confession by empaneling
    dual juries at a single trial, as the court did here, instead of
    ordering separate trials. (See People v. Anderson (2018) 
    5 Cal. 5th 372
    , 387; 
    Thompson, supra
    , 1 Cal.5th at p. 1085 [“ ‘[W]e
    have upheld the use of separate juries for jointly tried
    defendants, as an alternative to outright severance’ ”].)
    Flinner argues that the single trial raised issues under
    Bruton v. United States (1968) 
    391 U.S. 123
    (Bruton) and
    6
    In Zafiro v. United 
    States, supra
    , 506 U.S. at page 539, the
    high court explained that when defendants have been properly
    joined, antagonistic defenses call for severance “only if there is
    a serious risk that a joint trial would compromise a specific trial
    right of one of the defendants, or prevent the jury from making
    a reliable judgment about guilt or innocence.” As examples, the
    court pointed to the possibility that “evidence that the jury
    should not consider against a defendant and that would not be
    admissible if a defendant were tried alone is admitted against a
    codefendant” or that “[c]onversely, a defendant might suffer
    prejudice if essential exculpatory evidence that would be
    available to a defendant tried alone were unavailable in a joint
    trial.” (Ibid.) The dual-jury procedure appears to solve most or
    all such evidentiary problems, suggesting that antagonistic
    defenses do not require severance where the defendants have
    separately empaneled juries.
    27
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Crawford v. Washington (2004) 
    541 U.S. 36
    (Crawford) because
    the prosecution was permitted to introduce parts of Ontiveros’s
    postarrest confession through Detective Scully before Flinner’s
    jury. As we explain in detail below, no Bruton issue arose
    because Flinner and Ontiveros were tried by separate juries.
    Flinner does, however, establish that the trial court committed
    Crawford error in admitting parts of Ontiveros’s confession
    against Flinner. But it was not the nature of the single trial
    that produced this error: Before the high court decided
    Crawford, the trial court ruled portions of Ontiveros’s confession
    admissible against Flinner as statements against penal
    interest. The trial court’s error was in admitting Ontiveros’s
    statements in violation of the confrontation clause, not in
    denying Flinner’s severance motion. The basis for the trial
    court’s ruling — that Ontiveros’s statements were admissible
    against Flinner as statements against interest — would have
    permitted their introduction even at a separate trial. (See
    pt. II.B.7., post.)
    Flinner moved to sever his case again midtrial after
    Ontiveros’s cross-examination of the state’s witness Charles
    Cahoon. Defense counsel argued that Cahoon’s testimony as
    elicited by Ontiveros’s counsel was “not quite character
    assassination, but . . . awful close to it.” The trial court denied
    the motion. Cahoon testified that he was afraid of Flinner, that
    Flinner was manipulative, and that Cahoon was not involved in
    the murder, contrary to the allegations in an anonymous letter
    left on a police sergeant’s windshield. Defense counsel appeared
    most concerned with the trial court’s admission, over Flinner’s
    objection, of Cahoon’s statement that Flinner “is a very bad man
    and he should be stopped” and that “he doesn’t deserve to even
    be with us here on Earth,” given in response to a question by
    28
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Ontiveros’s counsel about why Cahoon belatedly came forward
    to Detective Scully with information implicating Flinner.
    Flinner does not now argue that the trial court abused its
    discretion in denying this second severance motion; instead, he
    lists Cahoon’s testimony as one illustration of how the
    antagonistic defenses unfairly prejudiced him. We disagree. As
    we explain later, the trial court did not err in admitting
    Cahoon’s statements, which could with equal propriety have
    been elicited by the prosecution. (See pt. II.B.1.c., post.)
    We also reject Flinner’s claim that reversal is required
    because the trial court’s failure to sever allowed Ontiveros to act
    as a “second prosecutor.” As we have previously explained in
    rejecting a similar argument, just “because the prosecution’s
    case will be stronger if defendants are tried together, or that one
    defense undermines another, does not render a joint trial
    unfair.” (People v. Bryant, Smith and Wheeler (2014) 
    60 Cal. 4th 335
    , 379.)
    Flinner argues that Ontiveros was permitted to introduce
    evidence damaging to his defense that the prosecution did not
    offer, but he does not establish that the prosecution would have
    been unable to offer the same evidence against him. Flinner’s
    argument focuses in particular on the admission of hearsay
    statements that he made to Gilberto Lopez that Flinner
    “shouldn’t have killed her” or “should not have had her killed,”
    referring to Keck. Although Flinner complains that Ontiveros
    and not the prosecution called Lopez and that Ontiveros’s
    counsel did not ask Lopez any question about Ontiveros, the fact
    remains that the prosecution could have offered the very same
    evidence against Flinner, regardless of whether the two
    defendants were jointly tried.
    29
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Flinner complains that Ontiveros was responsible for the
    admission of other pieces of damaging evidence as well, but the
    evidence in question was in fact introduced by the prosecution,
    not Ontiveros. For example, Flinner notes that “[i]t was
    Ontiveros’[s] counsel who had a police sergeant read a portion of
    an anonymous letter found on the windshield of his patrol car,”
    but it was actually the prosecution that called the sergeant as a
    witness and projected the relevant portion of the letter for the
    jury to read. Similarly, Flinner complains that Ontiveros’s
    counsel attempted to impeach a mental health expert called by
    Flinner to challenge Martin Baker’s competency and that
    Ontiveros’s counsel elicited testimony from the state’s forensic
    computer examiner that Flinner used his computer to print
    fraudulent checks. But in each case, Ontiveros’s questioning
    largely replicated the prosecution’s earlier work. Flinner does
    not argue that any of this evidence was inadmissible, and the
    fact that it was first introduced by the prosecution rebuts the
    argument that its damaging effects stemmed from the joint
    nature of the trial. In any event, “no denial of a fair trial results
    from the mere fact that two defendants who are jointly tried
    have antagonistic defenses” and one offers evidence “that is
    damaging to the other and thus helpful to the prosecution.”
    (People v. Turner (1984) 
    37 Cal. 3d 302
    , 313.)
    Flinner also points to a number of instances in the record
    where he claims that Ontiveros was permitted to ask
    inappropriate questions. In some of these instances, Flinner
    simply misreads the record. He suggests that Ontiveros’s
    counsel was permitted to present damaging “innuendo” evidence
    against Flinner when Ontiveros’s counsel asked prosecution
    witness Robert Pittman whether he had ever heard that
    Flinner’s first wife “had died mysteriously.” In fact, it was
    30
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Flinner’s counsel, not Ontiveros’s, who posed this question to
    Pittman. In other instances, Flinner objects to questioning by
    Ontiveros that was substantially the same as a line of
    questioning first posed by Flinner or the prosecution. Flinner
    objects to questions that Ontiveros’s counsel posed to witness
    Sterling Thomas about whether Flinner had asked Thomas to
    steal his Chevy SUV so that Flinner could file an insurance
    claim, whether Flinner had “hit on” Thomas’s fiancée, or
    whether Flinner said he wanted to “get rid of” his girlfriend
    (even though Thomas denied some of these conversations ever
    took place and said that others were in jest). But it was Flinner
    who called Thomas as a witness, and Flinner who first brought
    up the alleged conversation in which Flinner asked Thomas to
    steal his truck. As for Thomas’s testimony that Flinner said he
    wanted to “get rid of” his girlfriend, it was the prosecution that
    first elicited the testimony on cross-examination. In any event,
    regardless of whether Ontiveros was the first to ask the
    questions or merely followed up on the questions already asked
    by others, the jury was properly instructed that questions are
    not evidence, and we presume it followed the court’s
    instructions. (People v. Sanchez (2001) 
    26 Cal. 4th 834
    , 852.)
    Flinner argues that Ontiveros’s defense strategy reduced
    the People’s burden to prove Flinner’s guilt beyond a reasonable
    doubt, but we are not persuaded. “[T]his was not a case in which
    only one defendant could be guilty. The prosecution did not
    charge both and leave it to the defendants to convince the jury
    that the other was that person. Here the prosecution theory was
    that both defendants participated in, and were guilty of, the
    murder.” (People v. Cummings (1993) 
    4 Cal. 4th 1233
    , 1287.)
    The prosecution put on substantial evidence of Flinner’s guilt,
    including evidence that Flinner met with Ontiveros the day of
    31
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    the murder to run through the plan, that Flinner made
    incriminating statements before and after he was charged with
    Keck’s murder, and that he attempted to pay Ontiveros for his
    role in the crime.
    Finally, Flinner argues that the trial court’s failure to
    sever his case produced gross unfairness because Ontiveros used
    the codefendants’ single peremptory challenge to dismiss the
    original judge, ostensibly preventing Flinner from dismissing
    Judge Preckel for alleged bias.          As we have explained
    (pt. II.A.1.b.iv., ante), Ontiveros’s use of the single statutory
    peremptory challenge did not prevent the defense from raising
    a nonstatutory motion for recusal. Thus, any prejudice flowed
    from Flinner’s failure to object and not from the trial court’s
    failure to order severance. And, in any event, as we have
    explained, Flinner’s judicial bias claim fails on the merits; Judge
    Preckel’s presiding did not render Flinner’s trial unfair.
    B. Guilt Phase Issues
    1. Admissibility of Consciousness of Guilt and
    Witness Fear Evidence
    Flinner asserts that the trial court erred in admitting
    evidence that he obtained or planned to obtain the home
    addresses of persons connected to the trial, that he threatened
    the prosecutor, and that certain witnesses were afraid of or
    intimidated by him.
    Under the Evidence Code, “[e]vidence must be relevant to
    be admissible. (Evid. Code, § 350.) Moreover, even if relevant,
    it may be excluded if the court determines that its prejudicial
    impact substantially outweighs any probative value. (Id.,
    § 352.) We afford trial courts wide discretion in assessing
    whether in a given case a particular piece of evidence is . . . more
    32
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    prejudicial than probative.” (People v. Duff (2014) 
    58 Cal. 4th 527
    , 558.)
    Flinner argues that the challenged evidence was
    irrelevant and unduly prejudicial in violation of Evidence Code
    sections 350 and 352. He also argues that admission of the
    evidence violated his rights to due process and a reliable penalty
    determination under the Eighth and Fourteenth Amendments.
    We address each category of challenged evidence in turn.
    a. Flinner’s Attempt To Obtain Addresses of
    Witnesses, Judge, Prosecutor, and Potential
    Jurors
    Flinner first asserts that the trial court erred in admitting
    evidence that he obtained or planned to obtain the home
    addresses of various persons connected to his trial. Inmate
    Gregory Sherman, who was housed in the same area as Flinner
    at the county jail, was called as a prosecution witness. As noted
    above, Sherman had special privileges at the jail’s law library —
    including access to unmonitored phone calls and the internet —
    because he represented himself pro se. He also had past
    experience tracking down people’s addresses through public
    record searches. Sherman testified that after Flinner learned
    about his library privileges and skills, Flinner asked him for
    help in obtaining the addresses of prosecution witnesses, as well
    as the prosecutor, the judge, and the bailiff in his case.
    Flinner explained that he intended to sabotage the trial by
    flooding the witness pool with letters containing confidential
    information about the case; he expected this tactic would
    preclude the witnesses from testifying. He planned to make it
    look like the letters came from one of the lead detectives in his
    case or his prior defense attorney, and he told Sherman that he
    33
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    knew some people who he would then direct to “take . . . out” the
    person he framed. If that plan failed, Flinner had a “plan B”
    that he shared with Sherman: Flinner would try to ensure that
    the jurors selected to serve in his case were homeowners with
    uncommon names, so that he could easily track down their home
    addresses. As with the witness pool plan, Flinner would then
    send the jurors packets of information about the case intended
    to disqualify the jurors from serving. For this scheme, Flinner
    suggested to Sherman that he would make it look like the
    prosecutor sent the packets.
    The prosecution also called Catherine McLarnan, who
    previously dated Flinner. She testified that after she visited
    Flinner in jail, he sent her a package containing a list of names
    and addresses of witnesses, a letter to send to those witnesses,
    and instructions on how to prepare the letters. Flinner asked
    her to type up the letter, wear latex gloves while preparing the
    letters and envelopes, and use the address of his former defense
    attorney as the return address. He explained that the letter
    included evidence deemed inadmissible by his trial judge and
    that, by sending it to all the witnesses, he would be able to “ ‘ruin
    the People’s case.’ ” McLarnan testified that she did not follow
    Flinner’s directions and instead turned the materials from
    Flinner over to his defense investigator.
    Flinner argues that this evidence about his efforts to
    tamper with the witnesses and the jury was irrelevant and
    unduly prejudicial, but he does not point to a specific trial
    objection to this evidence. We thus agree with the Attorney
    34
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    General that the issue has been forfeited by lack of objection.7
    We reject the claim for lack of merit in any event. As the jury
    was instructed (with a version of CALJIC No. 2.06), a
    defendant’s efforts to suppress harmful evidence can be
    probative of the defendant’s consciousness of guilt. Sherman’s
    and McLarnan’s testimony concerning Flinner’s plans to tamper
    with the witnesses and jury pool was relevant to show his
    consciousness of guilt. Nor was this evidence was unduly
    prejudicial: None of this testimony suggested that Flinner
    intended to threaten or harm the jurors, as opposed to a
    detective or defense attorney, and we conclude that any
    prejudice that may have arisen from jurors’ awareness that
    7
    In response to the Attorney General’s forfeiture argument,
    Flinner points to an asserted trial court order that all defense
    objections are made on all relevant state and federal grounds.
    As we explain later in this opinion (see pt. II.B.3., post), the
    order in question did not operate to generally excuse Flinner
    from objection requirements. He also attempts to demonstrate
    that the trial court did, in fact, consider an objection to the
    evidence and overruled it. But there is nothing in the record to
    support the contention. Flinner invokes a “discussion regarding
    appellant’s alleged efforts to suppress or fabricate evidence,” but
    cites a transcript page that does not exist. Next, Flinner points
    to the trial court’s consideration of a pretrial motion which the
    court characterized as concerning “purported efforts by and on
    behalf of Mr. Flinner to fabricate and/or suppress evidence” but
    none of the documents (letters authored by Flinner) that the
    court went on to consider concern Sherman or McLarnan.
    Finally, Flinner points to a hearing in which, he says, the “court
    overrules defense objections to evidence regarding McLarnan.”
    But the record contains no indication that such a thing occurred
    at the hearing; instead, it appears from the record that the
    materials that McLarnan handed over to the defense
    investigator were first brought to the court’s attention at this
    hearing, and the court agreed to defense counsel’s request to
    consider the materials in camera at a later time.
    35
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Flinner sought out and may have discovered the jurors’
    addresses was outweighed by the probative value of this
    testimony.
    b. Flinner’s Threats to the Prosecutor
    Flinner also claims that the trial court erred in admitting
    portions of three letters he wrote expressing hatred toward the
    prosecutor and threats against the prosecutor or his family. The
    first is a letter that Flinner wrote to his mother, where he
    characterized the prosecutor as a “little maggot.” The letter goes
    on to state: “You’d think a guy who achieved as he is could afford
    more than a $263,000 mortgage. [¶] . . . [¶] . . . His wife must
    be unquestionably ill-bred, empty, and misguided being with
    him, either that or one hideous, sordid shrew with a back harrier
    [sic] than his own. . . . I hope he dies young. The Freedom of
    Information Act is a great thing. . . . Looking forward to getting
    out of here and moving to Chula Vista so I can hang out with all
    of my great friends.”
    The second letter is one that Flinner wrote to an inmate
    at another prison with whom Flinner corresponded frequently.
    It reads, in part: “Have you ever heard of the Freedom of
    Information Act? Why is it okay for him to know all about me,
    and yet I’m not supposed to know anything about him? . . . One
    cannot be a true adversary without knowledge of his opponent
    and his critical position in life. . . . [¶] . . . [¶] . . . He has me
    locked away in solitary confinement so as not to be able to talk
    to the other convicts, et cetera. But I ride four busses [sic] when
    I go to court and can speak to whomever I wish. Many people
    know the things that I want them to know. One thing is for sure,
    this shit is a long way from over. [¶] Anyway, just thought I’d
    36
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    put that out there in case this sorry piece of shit happens to read
    this, miserable mother fucker.”
    The third letter Flinner points to is one he sent to another
    inmate. The court admitted only part of this letter, which
    included the following statement: “By the way, the dicks [on top
    of each page of the letter] are for the D.A.’s memory. He’s [sic]
    trying to send him a subliminal message, actually a series of
    them. First, I will fuck him in front of his wife and kids when
    I’m free.”
    Before trial, the prosecution had sought to admit these
    and several other letters written by Flinner disparaging the
    prosecutor, illustrating Flinner’s knowledge of personal details
    about the prosecutor like his home address and wife’s name,
    disclosing such information to other inmates, and threatening
    harm to the prosecutor and his family. The prosecution argued
    that this evidence was relevant to showing Flinner’s efforts to
    intimidate the prosecutor and thereby hinder the prosecution of
    the case. Although these letters were sent to third parties and
    not directly to the prosecutor, the prosecution asserted that
    Flinner knew his letters were being photocopied and monitored
    by the authorities. Defense counsel objected to the admission of
    the letters, arguing that Flinner was merely “venting his
    frustrations regarding his situation rather than attempting to
    hinder the prosecution of this case” and was just trying to “get[]
    a rise out of” the prosecutor. To the extent the letters were
    relevant, Flinner urged, they should be excluded as unduly
    prejudicial. The court agreed with the prosecution that these
    letters supported the inference that Flinner was trying to alter
    the course of the prosecution by intimidating the prosecutor, but
    it carefully walked through the letters and excluded many
    entirely and others in part under Evidence Code section 352.
    37
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    We conclude the trial court did not err in admitting the
    portions of the three letters of which Flinner now complains. We
    agree with the trial court that these letters contained not-so-
    veiled threats against the prosecutor and his family, which were
    relevant to whether Flinner attempted to suppress evidence by
    obstructing the prosecution of his case and thus tend to
    demonstrate consciousness of guilt. (See People v. Hamilton
    (1985) 
    41 Cal. 3d 408
    , 429 [where the defendant knew his
    jailhouse letter would be copied and read by authorities, his
    reference to threats against the prosecutorial team made by an
    acquaintance, which were to be carried out if the defendant was
    convicted, constituted a form of “subtle attempt at
    intimidation”].) We also conclude that the court acted within its
    discretion in admitting under an Evidence Code section 352
    analysis the portions of the letters that Flinner points to here.
    We do not think the jury would be biased by the derogatory
    characterizations of the prosecutor as a “little maggot” or a
    “miserable mother fucker,” especially in light of the evidence of
    the actual crimes at issue in this case. The probative value of
    Flinner’s pointed references to details about the prosecutor’s
    personal life outweighs any prejudice that might have arisen
    from the jurors’ knowledge that Flinner was targeting the
    prosecutor. We cannot say the trial court abused its wide
    discretion in admitting these threats.
    Finally, Flinner suggests that it was unduly prejudicial to
    expose the jurors to both the violent threats Flinner made
    against the prosecutor and his attempts to collect the jurors’ own
    addresses. He reasons that the jurors might have inferred that
    he would retaliate against them or their families, too, and they
    would be prejudiced against him as a result. We conclude the
    trial court did not abuse its discretion by admitting either
    38
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    category of evidence. As we have already explained, the
    probative value of Flinner’s attempts to obtain jurors’ addresses
    and his threats against the prosecutor was significant, and we
    are not convinced that any additional prejudice arising from the
    synergy of these two strains of evidence substantially
    outweighed that probative value.
    c. Witnesses’ Fears of Flinner
    Flinner argues that the trial court erred in admitting the
    testimony of three witnesses in which each expressed fear of
    Flinner. The Attorney General argues that, in each instance,
    the witness’s fear of Flinner was relevant to the witness’s
    credibility and therefore admissible. We consider each witness’s
    testimony in turn.
    Witness Charles Cahoon testified about Flinner’s attempt
    to frame him for Keck’s murder. The prosecution sought to show
    that Flinner was responsible for planting a sock with bullets
    inside it in Cahoon’s car. Cahoon testified that he saw Flinner
    break into his apartment shortly before Cahoon found the sock
    in his car, and that Cahoon realized his car keys were missing
    shortly after the apartment break-in. On cross-examination,
    Flinner’s attorney elicited testimony that, when Cahoon first
    reported the incident to the police, Cahoon said the intruder
    looked like a Mexican person and resembled Flinner’s friend,
    Gilberto Lopez. During later cross-examination by Ontiveros’s
    counsel and redirect examination by the prosecution, Cahoon
    explained that he had always thought the intruder was Flinner
    but had been reluctant to name him because Cahoon was afraid
    of Flinner. Over Flinner’s objection, the trial court permitted
    Cahoon to explain why he ultimately chose to come forward and
    name Flinner: “Because I think he is a very bad man and he
    39
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    should be stopped. And I think he doesn’t deserve to even be
    with us here on Earth.”
    On recross-examination, Flinner’s counsel attempted to
    impeach Cahoon by portraying Cahoon as a biased witness who
    was trying to ensure Flinner’s conviction. Defense counsel
    elicited Cahoon’s testimony that Cahoon had been trying to find
    out what he “could do to go ahead and help to get [Flinner] off
    the street and away from the public eye and so he couldn’t hurt
    or kill anybody else.” And Cahoon confirmed, upon defense
    counsel’s followup, that this was his “angle” — that he did not
    like Flinner and did not think he “should be with us here.” At
    defense counsel’s request, the trial court struck other portions
    of Cahoon’s testimony as nonresponsive, including Cahoon’s
    statement that he was still scared of Flinner and thought “what
    he’s doing to [codefendant Ontiveros] is ridiculous.”
    We conclude the trial court properly admitted this
    testimony. Cahoon’s description of his initial fear in response to
    questioning by the prosecution and by Ontiveros’s counsel were
    relevant to Cahoon’s credibility: His fear of Flinner provided an
    explanation for why he did not immediately name Flinner as the
    home intruder. Cahoon did express strong negative feelings
    about Flinner alongside his fear; some of his statements held a
    potential for prejudice within the meaning of Evidence Code
    section 352. But the trial court did not abuse its broad discretion
    to balance that potential against the statements’ probative
    value in showing how Cahoon overcame his fear of testifying.
    We note as well that Cahoon’s later statements against Flinner
    — that Cahoon was testifying in order to get Flinner “off the
    street and away from the public eye and so he couldn’t hurt or
    kill anybody else” and that he did not think Flinner “should be
    with us here” — were elicited by Flinner’s own attorney,
    40
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    presumably believing these statements useful to show Cahoon’s
    bias. Flinner cannot claim error in admission of evidence he
    elicited. (See People v. Gutierrez (2002) 
    28 Cal. 4th 1083
    , 1139
    [if there was error, it was invited]; People v. Escobar (1996) 
    48 Cal. App. 4th 999
    , 1022, fn. 4 [rejecting defendant’s claim of
    inadmissibility of evidence where defendant “not only failed to
    object to the admission of the evidence, but . . . sought its
    admission”].)
    Next, Flinner argues that the trial court erred in
    admitting prosecution witness Ronald Millard’s statement that,
    although Flinner had never threatened or harmed him, Millard
    felt intimidated by Flinner. Millard, who had worked for
    Flinner, testified to aspects of the relationship between Flinner
    and Ontiveros. On cross-examination, Flinner’s attorney asked
    the following questions:
    “Q: Did Mr. Flinner ever threaten you personally?
    “A: No.
    “Q: Did Mr. Flinner ever touch you physically?
    “A: No.
    “Q: Did Mr. Flinner ever do anything to make you
    personally afraid of him where he said something to you
    concerning anything.
    “A: He’s a very intimidating man.”
    As with Cahoon’s later statements of fear, defense counsel
    initiated this line of questioning and did not ask the trial court
    to strike Millard’s answer that Flinner is “a very intimidating
    man,” the only portion of Millard’s testimony to which he now
    objects. Under these circumstances, his claim of error is not
    41
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    cognizable on appeal. (People v. 
    Gutierrez, supra
    , 28 Cal.4th at
    p. 1139.)
    Finally, Flinner returns to McLarnan’s testimony. The
    prosecutor asked McLarnan what she did upon receiving the
    letter from Flinner asking her to send letters to witnesses in his
    case. When she said that, at first, she “didn’t do anything with
    it” and ultimately turned it over to the defense investigator, the
    prosecutor asked whether she ever contacted police or the
    district attorney’s office to tell them about Flinner’s letter. She
    said she had not. The prosecutor proceeded to ask her whether
    she had been concerned about her family’s safety should Flinner
    find out about her decision not to help him. Over Flinner’s
    objection on grounds of relevance and undue prejudice, the trial
    court allowed McLarnan to answer that she “was concerned
    about Michael’s reaction” and she “was concerned for [her] son.”
    The prosecutor also introduced portions of a letter she sent to
    the defense investigator in which she wrote, “I’m seriously
    concerned for my family’s safety should Michael find out about
    this,” and queried, “Do you think we’ll need protection?”
    We conclude that this evidence was relevant. “Evidence
    that a witness is afraid to testify or fears retaliation for
    testifying is relevant to the credibility of that witness and is
    therefore admissible.” (People v. Burgener (2003) 
    29 Cal. 4th 833
    , 869.) McLarnan’s explanation of why she was afraid was
    “likewise relevant to her credibility” and its admission “well
    within the discretion of the trial court.” (Ibid.) McLarnan did
    not initially tell anyone about the letter that she received from
    Flinner and never handed the information over to the
    authorities; her fears of what Flinner would do if he found out
    about her actions were relevant to why she held this information
    so closely and did not come forward immediately with it, despite
    42
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    her understanding that the letter could be seen as tampering
    with witnesses and hampering Flinner’s trial. (People v.
    Mendoza (2011) 
    52 Cal. 4th 1056
    , 1085 [“a trial court has
    discretion, within the limits of Evidence Code section 352, to
    permit the prosecution to introduce evidence supporting a
    witness’s credibility on direct examination, particularly when
    the prosecution reasonably anticipates a defense attack on the
    credibility of that witness”].) And this evidence was not unduly
    prejudicial: Though McLarnan’s statements suggest she feared
    some kind of retaliation from Flinner, she did not testify that
    Flinner had ever threatened or harmed her, including during
    their prior relationship or when she visited him in prison. The
    trial court did not abuse its discretion under Evidence Code
    section 352 in admitting evidence of her concern.
    2. Flinner’s Derogatory Statements About Keck
    Flinner argues that the trial court improperly admitted
    derogatory and callous comments he made about Keck before
    and after her death. Tiffany Faye testified about a visit that
    Flinner made to the flower shop where she worked to purchase
    flowers for Keck’s funeral. During the visit, Flinner yelled at a
    woman driving by in a car, “Hey baby, I’m single now,” and
    laughed. In declining to add a message to accompany the
    flowers he purchased, Flinner told Faye, “Tammy is dead. It’s
    not like she can read it anyway,” and laughed again. David
    Pemberton, a contractor who met Flinner at their local Chamber
    of Commerce meetings, testified that Flinner referred to Keck
    as a “bitch,” “cunt,” and “slut” in front of her and others. Flinner
    contends that these statements should have been excluded as
    irrelevant or, even if relevant, as substantially more prejudicial
    than probative.
    43
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Before trial, the prosecution filed a motion in limine to
    introduce this and other evidence concerning Flinner’s strained
    relationship with Keck. The prosecution argued that this
    evidence was admissible in part because it “clearly rebuts
    [Flinner’s] claim that he ‘loved’ Tamra and therefore could not
    have killed her.” Flinner opposed the admission of much of this
    evidence, arguing that it was highly prejudicial and irrelevant,
    but acknowledged that some evidence of Flinner’s lack of grief
    after Keck’s death might properly come in. The trial court
    concluded that evidence of the strained nature of Flinner’s and
    Keck’s relationship was relevant and admissible to establish
    motive, identity, and state of mind, reasoning in part that
    “defendant is not entitled to have the jury determine his guilt or
    innocence on a false presentation of their relationship.” But the
    court restricted the evidence that the prosecutor could present
    to the jury based on an analysis under Evidence Code section
    352.
    We conclude the trial court properly admitted the
    contested testimony of Faye and Pemberton.                Flinner’s
    derogatory characterizations of Keck, made both in Keck’s
    presence and as well as in front of others, are relevant to proving
    his strained relationship with Keck and thus his relative
    willingness to have her killed in furtherance of his own material
    gain. His callous remarks in Faye’s presence shortly after
    Keck’s death are relevant to establishing his lack of sorrow, thus
    refuting the defense’s theory that Flinner was in love with Keck
    and therefore would not have been involved in her murder. And
    the probative value of these statements was not substantially
    outweighed by any prejudicial impact. These disparaging
    remarks were not particularly inflammatory considering the
    44
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    other evidence that Flinner arranged and facilitated a cold-
    blooded murder for financial gain.8
    3. Admissibility of Series of Writings Allegedly
    Authored by Flinner or at His Direction
    Flinner argues that the trial court erred in admitting a
    series of letters, a telephone call recording, and two bullet
    casings with “Tammy” and “Mike” written on them, all allegedly
    authored by Flinner or made at his direction. He asserts that
    none of these writings was properly authenticated, in violation
    of Evidence Code section 1401, as well as his right to confront
    the witness against him under the Sixth and Fourteenth
    Amendments. Flinner also contends that this evidence was
    irrelevant and substantially more prejudicial than probative,
    and that its admission thus violated Evidence Code sections 350
    and 352, as well as his rights to a fair trial and a reliable penalty
    determination under the Eighth and Fourteenth Amendments.
    With respect to a majority of these pieces of evidence,
    Flinner has forfeited his objection based on lack of
    authentication. Flinner argues that he preserved all his
    authentication claims for our review. Without fully explaining
    his argument on this point, he points to a pretrial ruling in
    which he claims the court granted his request that all objections
    by the defense be regarded as having been made on all relevant
    state and federal grounds. But this ruling was not a sweeping
    8
    Flinner briefly suggests that his comments about Keck
    were inadmissible hearsay. But he fails to explain how these
    comments were offered for the “truth of the matter stated” (Evid.
    Code, § 1200), as opposed to showing Flinner’s state of mind.
    Nor does he explain why, if considered hearsay, they would not
    fall within the exception for statements of a party opponent.
    (Id., § 1220.)
    45
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    authorization to remain silent at trial and raise objections for
    the first time on appeal. Instead, the trial court granted,
    without objection from the prosecution, what the court described
    as “a rather standard motion in a capital case” filed on behalf of
    codefendant Ontiveros and joined by Flinner: that defense
    objections as raised on the record may be deemed, without
    otherwise being expressly stated, to be objections based on
    California state constitutional as well as United States
    constitutional grounds. We have held that “[w]hen ‘new
    arguments do not invoke facts or legal standards different from
    those the trial court itself was asked to apply, but merely assert
    that the trial court’s act or omission, insofar as wrong for the
    reasons actually presented to that court, had the additional
    legal consequence of violating the Constitution . . . [a]
    defendant’s new constitutional arguments are not forfeited on
    appeal.’ ” (People v. Redd (2010) 
    48 Cal. 4th 691
    , 730, fn. 19; see
    also People v. Yeoman (2003) 
    31 Cal. 4th 93
    , 117 [explaining that,
    “[a]s a general matter, no useful purpose is served” by declining
    to consider such constitutional claims on appeal].) The trial
    court’s order did nothing more than confirm that a defendant
    does not forfeit an argument on appeal that is “merely a
    constitutional ‘gloss’ ” upon an objection properly raised below.
    (Redd, at p. 730, fn. 19.) But it is still generally the case that a
    defendant forfeits an argument on appeal where he fails to
    object at all to the evidence in the trial court or when he objects
    on substantively distinct grounds. (See, e.g., People v. Partida
    (2005) 
    37 Cal. 4th 428
    , 433–434 [“ ‘[W]e have consistently held
    that the “defendant’s failure to make a timely and specific
    objection” on the ground asserted on appeal makes that ground
    not cognizable’ ”].) The trial court did not rule otherwise. And
    46
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    here, Flinner failed to adequately object to most of the writings
    he now complains about.
    Under the Evidence Code, authentication of a writing —
    including documents, audio recordings, and “every other means
    of recording upon any tangible thing” (Evid. Code, § 250) — is
    required before the writing may be admitted in evidence (id.,
    § 1401). “Authentication is to be determined by the trial court
    as a preliminary fact ([id.,] § 403, subd. (a)(3)) and is statutorily
    defined as ‘the introduction of evidence sufficient to sustain a
    finding that it is the writing that the proponent of the evidence
    claims it is’ or ‘the establishment of such facts by any other
    means provided by law’ ([id.,] § 1400). The statutory definition
    ties authentication to relevance. As explained by the California
    Law Revision Commission’s comment to section 1400, ‘[b]efore
    any tangible object may be admitted into evidence, the party
    seeking to introduce the object must make a preliminary
    showing that the object is in some way relevant to the issues to
    be decided in the action. When the object sought to be
    introduced is a writing, this preliminary showing of relevancy
    usually entails some proof that the writing is authentic.’ ”
    (People v. Goldsmith (2014) 
    59 Cal. 4th 258
    , 266 (Goldsmith).)
    “The proponent’s assertion as to why the writing is relevant
    determines what the proponent claims the writing is, typically
    that it has some specific connection to a person or organization,
    whether through authorship or some other relation. It is this
    connection that must be proved to authenticate the writing.” (2
    McCormick, Evidence (7th ed. 2013) § 221, pp. 82–83, fns.
    omitted; Goldsmith, at p. 267 [“The first step is to determine the
    purpose for which the evidence is being offered. The purpose of
    the evidence will determine what must be shown for
    authentication, which may vary from case to case”].)
    47
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    “The foundation requires that there be sufficient evidence
    for a trier of fact to find that the writing is what it purports to
    be, i.e., that it is genuine for the purpose offered. [Citation.]
    Essentially, what is necessary is a prima facie case. ‘As long as
    the evidence would support a finding of authenticity, the writing
    is admissible. The fact conflicting inferences can be drawn
    regarding authenticity goes to the document’s weight as
    evidence, not its admissibility.’ ” 
    (Goldsmith, supra
    , 59 Cal.4th
    at p. 267.) We review a trial court’s finding that sufficient
    foundational facts have been presented to support a writing’s
    admissibility for abuse of discretion. (People v. Lucas (1995) 
    12 Cal. 4th 415
    , 466.)
    Here, the prosecution introduced the challenged writings
    for the purpose of showing that Flinner attempted to derail the
    investigation of Keck’s death by framing others for her murder
    while making himself appear innocent or, indeed, another target
    of her killer(s). Flinner argues that the prosecution failed to
    properly authenticate these writings because the prosecution
    did not make a sufficient preliminary showing that Flinner was
    the author of these writings or that he directed others to create
    them. The Attorney General responds that a preliminary
    showing that Flinner authored these writings was unnecessary
    because these writings were not offered for the truth of their
    contents but rather “for the jury to specifically consider whether
    Flinner authored or caused their production.” The Attorney
    General asserts that “when the content of the writing or the
    truthfulness of the assertions in the writing are not at issue,
    authentication as to authorship is largely unnecessary,” citing
    People v. Adamson (1953) 
    118 Cal. App. 2d 714
    , 720 (Adamson).
    As an initial matter, the Attorney General’s interpretation
    of Adamson is flawed and his reliance on the case is misplaced.
    48
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Adamson stands for a narrower proposition: namely, that
    preliminarily establishing the author of a writing is not
    necessary if the authorship of the writing is irrelevant. In
    Adamson, the prosecution had introduced a letter a witness
    received in order to establish that the witness had acted
    pursuant to the letter. 
    (Adamson, supra
    , 118 Cal.App.2d at
    p. 720.) The court concluded the prosecution was not required
    to make a preliminary showing that the letter was genuinely
    written by the alleged author, because “[w]hether it be genuine
    or a forgery, it was merely offered to show that [the witness] was
    motivated by it in his actions.” (Ibid.) In such instances, where
    authorship is irrelevant and the sole issues are whether a
    witness “receive[d] th[e] material, and if so what effect, if any,
    did it have on [his] mind[],” we have confirmed that establishing
    authorship is not necessary to properly authenticate a writing.9
    (People v. Marsh (1962) 
    58 Cal. 2d 732
    , 740 [discussing
    Adamson].)       Here, unlike in Adamson, the prosecution
    introduced the series of writings at issue precisely for the
    purpose of establishing that Flinner wrote them or directed
    their production. Authorship was not irrelevant; it was, rather,
    the central purpose for which the writings were introduced. For
    9
    The Adamson court’s conclusion that authentication is
    “not necessary” under these circumstances, however, is
    inaccurate as stated. (See Assem. Com. on Judiciary com., 29B
    pt. 5 West’s Ann. Evid. Code (2015 ed.) foll. § 1401, p. 203.)
    Although proof of genuineness was unnecessary in Adamson,
    “[u]nder the Evidence Code, the requirement of authentication
    would require a showing that the letter offered in evidence was
    in fact the one received and acted upon; and this is the
    preliminary showing that was found sufficient in the Adamson
    case.” (Assem. Com. on Judiciary com., 29B pt. 5 West’s Ann.
    Evid. 
    Code, supra
    , foll. § 1401, p. 203.)
    49
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    that reason, and contrary to the Attorney General’s contention,
    the prosecution was required to make a preliminary showing
    that these writings were what the prosecution claimed them to
    be: writings created by Flinner or at his direction.
    That said, we conclude that the writings at issue here were
    properly authenticated or could have been authenticated had an
    objection been timely raised. “ ‘[A] writing can be authenticated
    by circumstantial evidence and by its contents’ ” (People v.
    Landry (2016) 
    2 Cal. 5th 52
    , 87 (Landry)), and we agree with the
    Attorney General that “the prosecutor presented circumstantial
    evidence sufficient to enable the jury to ascertain that [Flinner]
    was responsible for the writings.” We address each of the
    challenged writings in turn.
    a. Anonymous Letter Implicating Cahoon
    A few weeks after Keck was killed, a police officer found
    an anonymous letter left on the windshield of his police car. The
    letter claimed that Charles Cahoon had killed Keck. Flinner did
    not object to the introduction of this evidence on authentication
    grounds, and his claim is thus forfeited.
    Even if Flinner had objected, we conclude it was not an
    abuse of discretion to admit the letter. The prosecution
    introduced circumstantial evidence that provided a sufficient
    preliminary showing for the prosecution to put the letter before
    the jury, which then had to make the ultimate factual
    determination of whether Flinner did indeed author it. During
    the trial, the prosecution introduced other evidence tending to
    prove that Flinner attempted to frame Cahoon for Keck’s
    murder. Cahoon testified that Flinner broke into his apartment
    and that shortly after the break-in, Cahoon realized that his car
    keys were missing. Around the time the police officer found the
    50
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    anonymous letter framing Cahoon, Cahoon found a sock with
    bullets inside it hidden in his car, which he turned over to
    Detective Scully. A criminalist specializing in DNA typing
    testified that he analyzed DNA found on the sock and concluded
    that it contained a mixture of DNA from Keck and a man. The
    male DNA matched Flinner’s profile in many respects and the
    criminalist concluded that it was quite likely that the DNA was
    in fact from Flinner. He also concluded that the male DNA could
    not have come from Cahoon. Although this circumstantial
    evidence of Flinner’s other attempts to frame Cahoon is not
    conclusive of the letter’s authorship, it was sufficient to admit
    the letter. “ ‘The fact conflicting inferences can be drawn
    regarding’ ” the letter’s authorship “ ‘goes to the document’s
    weight as evidence, not its admissibility.’ ” 
    (Goldsmith, supra
    ,
    59 Cal.4th at p. 267.)
    b. Anonymous Letter Implicating Software
    Developer
    In February 2001, Flinner’s mother received an
    anonymous letter posted from New York and made up of letters
    cut out of a magazine. The letter’s contents made little sense
    but included the following passage: “My continuing professional
    work is on improving the reliability of software. . . . We have got
    a head start of 100 years. Forced to kill the fiancé[e]. She knew
    too much.” The letter also said, “Keep him quiet.” Flinner failed
    to object to the admission of the letter; he therefore has forfeited
    his appellate claim that the letter should not have been
    admitted. The claim also fails on the merits. In the months
    leading up to the letter’s delivery, Flinner shared a theory that
    Keck was killed due to her knowledge of a scheme in which the
    North Korean government was seeking to have special gambling
    software delivered to mobsters in the United States. Flinner
    51
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    said that a friend and business partner, Rick Host, was involved
    in the scheme. Host passed away after Keck’s death, but Flinner
    claimed that just before Host’s death, Host told Flinner that
    Keck was killed because she had too much information about the
    gambling software. In light of this circumstantial evidence, one
    plausible inference is that Flinner had someone send the
    anonymous letter to Flinner’s mother to buttress Flinner’s story
    that Keck was killed due to her connection with the North
    Korean gambling software scheme, and not by Flinner.
    c. First Letter Implicating Host and Ontiveros
    Shortly after a press release announced that the police had
    taken Ontiveros into custody, police intercepted a letter
    addressed to Ontiveros. The letter was signed “Eli” and blamed
    Ontiveros for ruining a hit on “the target” and “Mike.” It reads,
    in part, “What were you doing? ICSC with Rick [Host] were
    acting on behalf of Kwan and they selected the target for a
    reason. . . . [Y]ou need to keep your mouth shut. If things go
    bad, blame everything on Mike.” The letter also expressed
    concern “that Rick may have told Mike all that was going on
    before his death,” and purported to remind Ontiveros that he
    was “instructed not to call or see Rick after . . . giving him back
    his car.” Flinner failed to object to this letter in the trial court
    and has thus forfeited the claim that it should not have been
    admitted. And, as with the letter to Flinner’s mother, it was not
    an abuse of discretion to admit this letter.             The other
    circumstantial evidence that Flinner was trying to pin blame on
    Ontiveros, Host, and the North Korean government supports
    the inference that Flinner forged this letter.
    52
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    d. Second Letter Implicating Host and Ontiveros
    Before trial, Judge Preckel received a letter written in
    broken English from a person claiming to know Ontiveros. The
    letter asserted that “a man named Rick” paid Ontiveros “to kill
    the girl.” It explained that Keck’s boyfriend — who “never know
    about this” — lent a car to Rick, who then lent it to Ontiveros.
    Rick told Keck to pick up Ontiveros, who then shot her in the
    head. The letter was signed “A.” Flinner did not object to the
    admission of the letter and has forfeited his challenge on
    authentication grounds. The challenge is also meritless. As
    discussed above, the prosecution introduced other evidence
    tending to prove that Flinner tried to implicate Rick Host in
    Keck’s death. And the prosecution also introduced other
    evidence that Flinner attempted to pin the blame for Keck’s
    death on Ontiveros: Flinner sent a series of letters to religious
    organizations claiming that Ontiveros killed Keck. He also sent
    a letter to United States Representative Duncan Hunter
    (discussed below) claiming that Ontiveros killed Keck and that
    her death was related to the gambling software scheme. In light
    of this other evidence making it possible to infer that Flinner
    caused this letter to be sent as part of his plan to shift blame
    from himself to Host and Ontiveros, it was not an abuse of
    discretion to admit the letter.
    e. Anonymous Phone Call Implicating “Ernesto”
    A few days after Keck’s murder, the sheriff’s department
    received a phone call from a Spanish-speaking woman who
    declined to identify herself. She claimed that a man named
    Ernesto told her that he killed Keck because he wanted to take
    revenge on Flinner. The woman explained that Ernesto “had
    had some problems with Mike like . . . like 10 years ago.” And
    she said that Ernesto told her that Keck had been driving a
    53
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    white Mustang the day of the murder, that Ernesto went to Vons
    or a gas station to pick her up, and that they went to a dead-end
    street where Ernesto “killed her with a 45.” The Attorney
    General concedes that Flinner objected to the introduction of
    this phone call on authenticity grounds.
    We conclude the trial court acted within its discretion in
    overruling the defense objection and admitting the phone call.
    Days after the sheriff’s department received the anonymous call,
    Flinner passed along to Detective Scully a voicemail message
    that Flinner received from a man with a “strong, Hispanic
    accent.” The caller said, “Mike, I see your wife Sunday [the day
    of the murder]. I see you next. Bye.” Flinner explained to
    Detective Scully that “[t]he only time [he] ever had a problem
    with anybody that was Hispanic” was 10 years earlier, when he
    got into an argument with a group of “Mexican folks.” The police
    had not told Flinner about the anonymous call claiming that
    Ernesto had killed Keck in revenge for a decade-old problem.
    One possible inference in light of this evidence is that the
    anonymous caller was telling the truth about Ernesto. But
    another inference, in light of the other, substantial evidence that
    Flinner attempted to frame others for Keck’s death, is that
    Flinner arranged for the initial anonymous phone call to be
    placed to the sheriff’s department to deflect attention from
    himself. The factual determination of whether Flinner was
    responsible for the call was properly put to the jury. Again,
    “ ‘[t]he fact conflicting inferences can be drawn regarding’ ” the
    call’s origin goes to the call’s weight and not its admissibility.

    , 59 Cal.4th at p. 267.)
    54
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    f. Bullets with “Mike” and “Tammy” Written on
    Them
    During the investigation, Flinner’s father found a
    container on his property with two bullets in it, which he turned
    over to the police. One was a spent casing with “Tammy”
    written on it, and the other was a live bullet with “Mike” written
    on it. The bullets were of the same caliber and make as the
    bullet that killed Keck. James Theodorelos, a cooperating
    informant who met Flinner in prison, testified that Flinner told
    him that Flinner had “put a few bullets on his parents’ property,
    one had been spent, with the initial of [Keck’s] name and the
    other one was the initial of [Flinner’s] name.” Flinner did not
    object to the introduction of the bullets and has forfeited the
    claim that they were improperly admitted. In any event, in light
    of Theodorelos’s testimony linking Flinner to the bullet writings,
    the trial court acted within the bounds of its discretion in
    admitting evidence of the two bullets.
    g. Letters to John Martin
    One of Flinner’s fellow inmates, John Martin, turned over
    to Detective Scully two letters that Flinner had allegedly
    written. In the first letter, the author claimed that Theodorelos
    turned on the author: “You see, [Theodorelos] has taken all of
    what I’ve shared about matters and twisted them up into his
    favor, saying that I told him that I sent the letter from the east
    to my parents, that I put . . . the casings on my dad’s property et
    cetera.” The letter also asks Martin to “remember the times . . .
    I had mentioned things like how my folks had received threats
    from the east coast and how my father found shell casings on his
    property and things about my business partner telling you that
    Asians were involved in that deal with my wife and things like
    that.” The second letter, which appears to respond to an
    55
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    intermediate letter from Martin, laments that Martin has
    “decided to flip the script” and says that “the district attorney’s
    office will invariably find their way to you now because of this
    letter I just got from you.” The trial court overruled defense
    counsel’s objection to these letters on foundation and hearsay
    grounds, and the Attorney General does not argue that Flinner
    forfeited his authentication objection to them.
    We conclude the trial court did not err in admitting these
    letters because their contents and other circumstantial evidence
    presented by the prosecution sufficiently authenticated the
    letters. The content of the first letter connects it to Flinner: The
    letter discusses the bullet casings that Flinner’s father found,
    the letter that his mother received from New York (a threat from
    “the east coast”), and the theory that Keck was tied up in a “deal”
    with some “Asians” (similar to the North Korean gambling
    software scheme theory). It also faults Theodorelos, the same
    man who testified against Flinner at trial, for cooperating with
    the prosecution. (See 
    Landry, supra
    , 2 Cal.5th at p. 87 [relying
    on the contents of a letter to support the letter’s authenticity,
    even where the information relayed in the letter may have been
    known by individuals other than the alleged author]; see also
    Evid. Code, § 1421 [“A writing may be authenticated by evidence
    that the writing refers to or states matters that are unlikely to
    be known to anyone other than the person who is claimed by the
    proponent of the evidence to be the author of the writing”];
    id., § 1410 [“Nothing
    in this article shall be construed to limit the
    means by which a writing may be authenticated or proved”].)
    Though the second letter does not contain similar references to
    personal information about Flinner and his case, the jury could
    reasonably infer from its contents that it was part of the same
    conversational chain; the letter reads as if it is a reply from
    56
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Flinner to a letter sent by Martin addressing Flinner’s first
    letter. (Cf. Evid. Code, § 1420 [“A writing may be authenticated
    by evidence that the writing was received in response to a
    communication sent to the person who is claimed by the
    proponent of the evidence to be the author of the writing”].)
    h. Letter to Member of Congress
    While in jail before trial, Flinner wrote a letter to United
    States Representative Duncan Hunter. In the letter, Flinner
    explained that his former employee was responsible for Keck’s
    murder, that “the Korean gaming industry” arranged the
    murder because Keck “was in possession of crucial software
    desired to promote and advance political payoffs,” and that
    Flinner had learned all of this from “a now deceased business
    associate . . . on his death bed.” Flinner did not raise an
    authentication objection in the trial court and has forfeited that
    claim. In any event, the letter was properly authenticated.
    Before the letter was introduced, the prosecution had Detective
    Scully explain how he had requested a mail cover for Flinner’s
    jail mail and that he had accordingly received photocopies of all
    Flinner’s incoming and outgoing mail, including the letter to
    Representative Hunter. (See, e.g., 
    Landry, supra
    , 2 Cal.5th at
    p. 87.)
    Although Flinner lumps this letter in with the other
    writings to which he objects on authentication grounds,
    Flinner’s complaint about this letter is primarily based on other
    concerns. Specifically, Flinner claims that jail employees
    violated Penal Code sections 2600 and 2601 in reading his letter
    to Representative Hunter and asserts that the letter should
    have been suppressed on that basis. Penal Code section 2601,
    subdivision (b) lists a series of civil rights that a person
    57
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    sentenced to prison retains, including the right “[t]o correspond,
    confidentially, with any member of the State Bar or holder of
    public office, provided that the prison authorities may open and
    inspect incoming mail to search for contraband.” (Italics added.)
    Penal Code section 2600, subdivision (a) provides that an inmate
    may be deprived of those rights only “as is reasonably related to
    legitimate penological interests.” Flinner did not object to the
    introduction of his letter to Representative Hunter on this or
    any other ground in the trial court and has thus forfeited this
    claim. Any error would also be harmless under any standard,
    given the wealth of similar evidence that Flinner attempted to
    place blame for Keck’s murder on the North Korean gambling
    industry and various employees and associates.
    In sum, Flinner’s objections to these eight writings are all
    either forfeited or meritless. We also reject Flinner’s claim that
    these writings were irrelevant or substantially more prejudicial
    than probative (Evid. Code, §§ 350, 352): These writings
    supported the prosecution’s theory that Flinner attempted to
    obstruct the investigation and prosecution of the case, from
    which the jury could properly infer a consciousness of guilt. And
    none of the letters created a substantial risk of undue prejudice.
    4. Admissibility of Flinner’s Statements Suggesting
    He Killed Keck
    Flinner contends that the trial court erred in admitting
    statements he made to his friend Gilberto Lopez, suggesting
    that Flinner killed Keck or had Keck killed. Flinner argues that
    these statements were hearsay and that they are insufficiently
    reliable to admit as statements against interest. Even if these
    statements were not inadmissible hearsay, he asserts, they
    should have been excluded as substantially more prejudicial
    than probative. He maintains that the admission of these
    58
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    statements violated his rights to confrontation, a reliable
    penalty determination, and due process under the Sixth, Eighth,
    and Fourteenth Amendments.
    Lopez testified that a few days after Keck’s murder he
    went out to dinner with his girlfriend Marie Locke and
    Flinner.10 He recalled Flinner having two large drinks and
    described him as becoming “tipsy” and seeming “really sad,
    really down.” During the meal, Flinner stated, “I shouldn’t have
    killed her.” On cross-examination, Lopez acknowledged Flinner
    may have just been “talking trash” that night, and that Lopez
    had thought at the time that Flinner was blaming himself but
    did not think Flinner was, in fact, responsible for Keck’s death.
    Lopez also testified about another occasion after the murder, in
    which Flinner had taken sleeping pills and was “acting all
    groggy, mumbling.” While Lopez was helping Flinner up to his
    bed, Flinner said, “I shouldn’t have killed her.”
    Flinner’s hearsay objection to the admission of this
    testimony lacks merit. Hearsay is an out-of-court statement
    offered for the truth of the matter asserted and is generally
    10
    Flinner made no objection to Lopez’s testimony. The
    hearing to which Flinner points as containing an objection
    instead concerned a defense request for a mistrial arising from
    a related, but significantly different, event: The subsequently
    stricken double-hearsay testimony (discussed further below) of
    Lopez’s girlfriend, Marie Locke, about Lopez’s relation to her of
    Flinner’s statement in the restaurant. In arguing for a mistrial,
    defense counsel at no point suggested that Lopez’s testimony
    about the statement would be inadmissible. The court denied
    the mistrial motion and a related motion to strike the testimony
    of an investigator but did not rule on any question regarding
    testimony by Lopez himself. Despite the lack of an objection,
    the Attorney General does not assert the claim is forfeited.
    59
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    inadmissible. (Evid. Code, § 1200.) But there are a number of
    exceptions to this rule. One, the party-admission exception
    codified in Evidence Code section 1220, covers “[e]vidence of a
    statement . . . when offered against the declarant in an action to
    which he is a party . . . .” Flinner was of course a party to this
    action. The parties focus on another, related exception to the
    hearsay rule, the exception for statements against interest:
    “Evidence of a statement by a declarant having sufficient
    knowledge of the subject is not made inadmissible by the
    hearsay rule if the declarant is unavailable as a witness and the
    statement, when made . . . so far subjected him to the risk of
    civil or criminal liability . . . that a reasonable man in his
    position would not have made the statement unless he believed
    it to be true.” (Id., § 1230.) “The proponent of such evidence
    must show that the declarant is unavailable, that the
    declaration was against the declarant’s penal interest when
    made and that the declaration was sufficiently reliable to
    warrant admission despite its hearsay character.” (People v.
    Duarte (2000) 
    24 Cal. 4th 603
    , 610–611 (Duarte).)               “In
    determining whether a statement is truly against interest
    within the meaning of Evidence Code section 1230, and hence is
    sufficiently trustworthy to be admissible, the court may take
    into account not just the words but the circumstances under
    which they were uttered, the possible motivation of the
    declarant, and the declarant’s relationship to the defendant.”
    (People v. Frierson (1991) 
    53 Cal. 3d 730
    , 745.) We review the
    application of the statement against interest exception to the
    particular facts of a case for abuse of discretion, but whether a
    trial court has correctly construed Evidence Code section 1230
    is a question of law that we review de novo. (People v. Grimes
    (2016) 
    1 Cal. 5th 698
    , 712.)
    60
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    The trial court did not abuse its discretion in admitting
    Flinner’s statements to Lopez, regardless of whether we focus
    on the statement of party opponent exception in Evidence Code
    section 1220 or the statement against interest exception in
    Evidence Code section 1230. Although Lopez’s testimony was
    offered by codefendant Ontiveros rather than by the People, it
    was nonetheless “offered against” Flinner within the meaning of
    Evidence Code section 1220. As discussed earlier, Ontiveros’s
    defense was antagonistic to Flinner’s: Ontiveros sought to show
    Flinner manipulated him into participating in Keck’s killing,
    while Flinner denied all involvement. Lopez’s testimony that
    Flinner took responsibility for killing Keck clearly harmed
    Flinner’s case, as well as helping Ontiveros’s. (Cf. People v.
    Allen (1976) 
    65 Cal. App. 3d 426
    , 433 [to be relevant under Evid.
    Code, § 1220, “the statement must assert facts which would
    have a tendency in reason either (1) to prove some portion of the
    proponent’s cause of action, or (2) to rebut some portion of the
    party declarant’s defense”].)
    As for section 1230, Flinner does not dispute that he was
    “unavailable as a witness” within the meaning of Evidence Code
    section 1230, since he had asserted his Fifth Amendment right
    not to testify. And his statements that he should not have killed
    Keck are, on their face, clearly contrary to his penal interests as
    they admit culpability for her murder.
    Flinner nevertheless argues that the circumstances
    surrounding the two statements establish that they are not
    sufficiently disserving of his interests nor sufficiently reliable to
    justify admission. Flinner notes that he was under the influence
    of alcohol or sleeping pills when he allegedly made these
    statements and that Lopez may not have taken them literally.
    He relies on 
    Duarte, supra
    , 
    24 Cal. 4th 603
    , in which the
    61
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    declarant admitted shooting at a house, but did so by
    minimizing his own culpability, suggesting that the defendant
    bore a greater culpability for the crime than the declarant. The
    declarant’s statement was made to police shortly after he had
    been arrested and after he had learned that the police had
    evidence linking him to the crime. We held that not only were
    portions of the declarant’s statement improperly admitted
    because they were not “ ‘specifically disserving’ ” of his penal
    interest (id. at p. 613), but also that under these circumstances
    — “ ‘where a declarant in police custody seeks to exculpate
    himself by implicating another suspect’ ” — the statement
    “lacked sufficient indicia of trustworthiness” and was
    inadmissible as a whole (id. at p. 618).11 But here, by contrast,
    no portion of Flinner’s statements sought to shift blame for
    Keck’s death away from himself, and he made the statements to
    a close friend, first at an intimate dinner and then in the privacy
    of his home. While the statements were made under the
    influence of alcohol or sleeping pills, no testimony suggests that
    Flinner was unable to understand what he was saying. (Cf. U.S.
    v. Two Shields (8th Cir. 2007) 
    497 F.3d 789
    , 792–793 [where
    declarant made nonverbal statement at hospital with blood
    alcohol level of .389 and was described as “unintelligible” by
    doctor, he could not appreciate that the statement was against
    11
    Flinner erroneously reads the Duarte court as including
    the declarant’s intoxication at the time of the statement as one
    of the circumstances undermining the reliability of the
    statement. But the declarant in Duarte had emphasized he was
    very drunk at the time of the shooting, as part of his effort to
    reduce his own culpability. (
    Duarte, supra
    , 24 Cal.4th at p. 615.)
    The Duarte declarant was not intoxicated at the time he made
    the disputed statement against interest to the police, and the
    case thus does not serve Flinner’s purposes.
    62
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    his interests and thus it lacked sufficient indicia of reliability
    and was inadmissible].) And finally, while the jury was
    certainly entitled to consider Lopez’s relatively innocuous
    interpretation of Flinner’s comments, Lopez’s interpretation
    could not have precluded the jury from drawing a more
    incriminating inference. Under these circumstances, the trial
    court did not abuse its discretion in admitting Flinner’s hearsay
    statements as statements against his penal interest.
    Nor were these statements inadmissible under Evidence
    Code section 352 as substantially more prejudicial than
    probative. The prejudice contemplated by section 352 typically
    involves a potential for evoking an emotional bias against the
    defendant on legally irrelevant or improper grounds; it is not the
    “ ‘ “damage to a defense that naturally flows from relevant,
    highly probative evidence.” ’ ” (People v. Scott (2011) 
    52 Cal. 4th 452
    , 491.) Nothing in Flinner’s statements that he should not
    have killed Keck would inflame the emotions of the jury in this
    way.
    In sum, we conclude the trial court properly admitted
    Flinner’s statements to Lopez. We thus reject Flinner’s
    argument that the admission of these statements violated his
    Sixth, Eighth, and Fourteenth Amendment rights.12
    12
    Having concluded that Lopez’s testimony was properly
    admitted, we reject Flinner’s argument that the improper
    admission of the testimony “aggravated” the harm caused by the
    stricken testimony of Lopez’s girlfriend, Marie Locke. Locke,
    who was at the dinner with Flinner and Lopez, testified about
    the dinner before Lopez did. She stated that Lopez told her that
    Flinner said, “I shouldn’t have killed her” that night, but that
    she had not personally heard the statement. The trial court
    63
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    5. Admissibility of Evidence of Keck’s Pregnancy
    Flinner argues that the trial court erred in admitting
    evidence that Keck may have been pregnant when she was
    killed. He asserts that evidence of Keck’s pregnancy was not
    relevant to any issue in dispute and that, even if relevant, its
    probative value was substantially outweighed by its prejudicial
    impact on the jury. Flinner also claims the admission of this
    evidence violated his rights to a reliable penalty determination
    and due process under the Eighth and Fourteenth Amendments.
    Before trial, the prosecution moved to admit evidence
    about Flinner’s strained relationship with Keck — including
    evidence of Flinner’s displeasure with her possible pregnancy —
    as relevant to establishing his motive for her murder and
    because it tended to refute Flinner’s claim that he was deeply in
    love with Keck, wanted to marry her, and wanted to father her
    child. Included in this motion was the prosecutor’s plan to
    introduce the testimony of Melissa Henderson and Nathalie
    Reed, who would each testify that Flinner discussed Keck’s
    pregnancy with her soon after Keck’s murder and expressed
    displeasure with the pregnancy. Flinner objected generally to
    evidence of his strained relationship with Keck, arguing it was
    irrelevant because the prosecution’s theory of the case was that
    Flinner had Keck killed in order to collect insurance money, not
    because of any relationship problems. Although the trial court
    excluded some of the evidence of the state of Keck’s and Flinner’s
    properly struck this portion of Locke’s testimony as inadmissible
    double hearsay and admonished the jury to disregard it. We
    presume the jury followed the court’s instructions as to Locke’s
    testimony (People v. 
    Sanchez, supra
    , 26 Cal.4th at p. 852), and
    Lopez’s testimony clearly did not suffer from the same defect.
    64
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    relationship as substantially more prejudicial than probative
    under Evidence Code section 352, it admitted much of it,
    including the planned testimony of Henderson and Reed.
    Defense counsel preserved the objection that this evidence was
    irrelevant and, even if relevant, should have been excluded
    under Evidence Code section 352. Also before trial, Flinner
    objected to the planned expert testimony of the pathologist who
    conducted Keck’s autopsy that Keck’s ovaries and uterus
    suggested that she may have been in the early stages of
    pregnancy at the time of her death.
    At trial, the prosecutor introduced photos of a pregnancy
    test found in Keck’s truck at the scene of the crime, as well as a
    Walmart receipt showing that she had purchased the test just
    before she was killed. Henderson testified that she met Flinner
    on a phone chat line in June 2000, shortly after Keck’s death,
    and that Flinner told her his fiancée had been pregnant and he
    was “dreading her being pregnant.” Reed testified that she
    worked at a casino that Flinner frequented and that after Keck’s
    death, Flinner said Keck was “lying” about the pregnancy “and
    she was trying to get him to marry her and he wasn’t going to
    do that.” Defense counsel renewed his objection on Evidence
    Code section 352 grounds, and the trial court again overruled
    the motion. Kim Milan then testified that she met Flinner
    through Lopez and during one conversation asked Flinner if he
    had killed Keck. He replied, “I know they think I did it, but why
    would they want to believe that? She was pregnant with my
    baby and we were about to be married.” Gregory Sherman, who
    met Flinner in jail, testified that Flinner discussed his “wife”
    and said that she was pregnant when she was killed. Over
    Flinner’s objection, the prosecutor introduced letters that
    Flinner wrote to religious organizations from jail, blaming a
    65
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    former employee for killing Keck after an affair. In these letters,
    Flinner references Keck’s pregnancy, speculating that she was
    having an affair with the former employee that led to the
    pregnancy. Finally, the pathologist testified that the state of
    Keck’s ovaries and uterus were suggestive of pregnancy but
    conceded on cross-examination that he could not say for sure
    that she was pregnant.
    Although Flinner now claims error in the admission of all
    evidence concerning Keck’s pregnancy, he did not raise all of
    these objections at trial. In particular, he did not object to the
    relevant portions of the testimony of Milan and Sherman, nor to
    the photos of the pregnancy test and Walmart receipt. Flinner’s
    objection as it applies to these pieces of evidence is thus
    forfeited.
    His objection to all evidence concerning Keck’s pregnancy
    as irrelevant or unduly prejudicial also fails on the merits. As
    at trial, Flinner argues that evidence of Keck’s pregnancy was
    irrelevant because the prosecution’s theory of the case was that
    Flinner arranged Keck’s death in order to collect on her life
    insurance policy, and there was no evidence suggesting that she
    was pregnant, or that Flinner believed she was, when he insured
    her life. As support for his argument, Flinner points to People
    v. Cash (2002) 
    28 Cal. 4th 703
    , 729, where we held that an
    attempted murder victim’s pregnancy was “clearly irrelevant” to
    any issue in the case. There, the defendant shot the victim in
    the course of committing a robbery and had no personal
    relationship with the victim apart from renting a room in her
    boyfriend’s house. Neither the defendant’s relationship to the
    victim nor the victim’s pregnancy had any bearing on the case.
    Here, by contrast, Flinner’s displeasure with Keck’s pregnancy
    provides an additional motive for her murder and is probative of
    66
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    why he decided to have her killed at the time he did. Flinner’s
    belief that Keck was pregnant is also relevant to the financial
    motivations for Keck’s murder, insofar as Flinner had expressed
    irritation with the financial strain that Keck placed on him,
    which might be expected to increase with the arrival of a new
    baby. Keck’s own belief that she may have been pregnant, as
    evidenced by the pregnancy test found in her car, and the
    pathologist’s testimony that Keck may have been pregnant, are
    relevant because they tend to corroborate Flinner’s belief that
    Keck was pregnant.
    We also reject Flinner’s claim that this evidence is
    substantially more prejudicial than probative. The kind of
    evidence that Evidence Code section 352 excludes is that which
    “ ‘ “uniquely tends to evoke an emotional bias against the
    defendant as an individual and which has very little effect on
    the issues.” ’ ” (People v. 
    Scott, supra
    , 52 Cal.4th at p. 491.) We
    recognize that in some instances, as in Cash, a victim’s
    pregnancy may have little or no relevance to the guilt phase of
    a trial and may serve only to inflame the emotions of the jury.
    But here, Keck’s possible pregnancy was probative of Flinner’s
    motive for her murder, and — against the backdrop of evidence
    that he hired a hitman to kill his teenage fiancée for insurance
    money — we do not think this evidence was so uniquely
    damaging as to require its exclusion. Flinner also argues that
    the pathologist’s testimony, even if relevant, was too speculative
    to present to the jury in light of its prejudicial impact. The
    pathologist properly presented his expert opinion based on the
    autopsy; that he could not say for sure that Keck was pregnant
    goes to the weight a reasonable juror would assign it, not its
    admissibility.
    67
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    We conclude the trial court did not abuse its discretion in
    admitting evidence of Keck’s possible pregnancy and reject
    Flinner’s statutory and constitutional claims to the contrary.
    6. Martin Baker’s Competence to Testify
    Through the testimony of Martin Baker and other
    witnesses, the prosecution sought to show Flinner had
    attempted to frame Baker for Keck’s murder. Flinner contends
    that Baker was incompetent to testify under Evidence Code
    section 701, subdivision (a) and lacked the requisite capacity to
    perceive and recollect in order to testify under Evidence Code
    section 702, subdivision (a). He argues that the trial court’s
    failure to disqualify Baker as a witness and refusal to strike
    Baker’s incoherent testimony violated his Sixth, Eighth, and
    Fourteenth Amendment rights to cross-examination, due
    process, and a reliable penalty determination.
    When a witness’s competency to testify at all, or to testify
    as to a particular matter, is questioned, we start from the
    general rule that “[e]xcept as otherwise provided by statute,
    every person, irrespective of age, is qualified to be a witness and
    no person is disqualified to testify to any matter.” (Evid. Code,
    § 700.) A person is completely disqualified from testifying under
    Evidence Code section 701, subdivision (a) if he or she is
    “(1) [i]ncapable of expressing himself or herself concerning the
    matter so as to be understood . . . or [¶] (2) [i]ncapable of
    understanding the duty of a witness to tell the truth.” “Capacity
    to communicate, or to understand the duty of truthful
    testimony, is a preliminary fact to be determined exclusively by
    the court, the burden of proof is on the party who objects to the
    proffered witness, and a trial court’s determination will be
    68
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    upheld in the absence of a clear abuse of discretion.” (People v.
    Anderson (2001) 
    25 Cal. 4th 543
    , 573 (Anderson).)
    Here, the record does not support the claim that Baker
    lacked the capacity to communicate so as to be understood or
    that he was unable to understand the duty of truthful testimony.
    Baker worked for Flinner’s landscaping business.               The
    prosecution called Baker as a witness to testify that Flinner
    tried to frame Baker for Keck’s death and to establish the
    independent poisoning charge. When the prosecution first
    called Baker, the court held a preliminary Evidence Code
    section 402 hearing in front of the jury to “assess Mr. Baker’s
    apparent condition and circumstances,” asking the prosecution
    to first “inquire of Mr. Baker as to who he is and what he’s been
    doing presently and in the recent past,” without “get[ting] into
    any substantive matters.” Baker demonstrated his ability to
    communicate when he testified as to his early life, his education,
    and his family. Flinner points out that Baker initially refused
    to answer questions concerning his siblings’ ages, saying, “I
    plead the 5th,” but this does not establish that Baker did not
    understand his duty to testify truthfully. His reluctance to
    respond stemmed from his sense that the question was “pretty
    personal” and that the case “has nothing to do with [his] family,”
    but he acquiesced as soon as the court admonished him that as
    a witness, he must answer questions honestly and to the best of
    his ability. We are satisfied that the trial court did not abuse its
    discretion in concluding that, although Baker may be “a bit
    different,” he was nevertheless qualified to testify. (See People
    v. Lewis (2001) 
    26 Cal. 4th 334
    , 361 [witness diagnosed as having
    intellect of a seven year old was not disqualified from testifying
    even though he “often responded in incomplete, sometimes
    69
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    nonsensical, sentences,” and testified that he “ ‘heard’ ” blood
    and knew how money “ ‘sounds’ ”].)
    Even if a witness is not disqualified as incompetent under
    Evidence Code section 701, subdivision (a), his or her testimony
    on a particular matter (other than expert opinion testimony) is
    inadmissible “unless [the witness] has personal knowledge of
    the matter.” (Id., § 702, subd. (a).) “In order to have personal
    knowledge, a witness must have the capacity to perceive and
    recollect.” (People v. 
    Lewis, supra
    , 26 Cal.4th at p. 356.) “A
    witness challenged for lack of personal knowledge must
    nonetheless be allowed to testify if there is evidence from which
    a rational trier of fact could find that the witness accurately
    perceived and recollected the testimonial events. Once that
    threshold is passed, it is for the jury to decide whether the
    witness’s perceptions and recollections are credible.” 
    (Anderson, supra
    , 25 Cal.4th at p. 574.)
    Our review of the record confirms that, although Baker
    departed on odd and incoherent digressions during his
    testimony, there was substantial evidence from which a rational
    trier of fact could conclude that Baker perceived and recollected
    the events of the night that Flinner poisoned him and attempted
    to frame him for Keck’s murder. Flinner points to isolated
    portions of Baker’s testimony that Flinner claims show that
    Baker’s mental illness or drug use rendered him unable to
    perceive and recollect the events of that night. For instance,
    when asked at what time he began to feel less groggy after
    eating the chili provided by Flinner, Baker responded: “A few
    days after that. It was like a reoccurring of a myth is what I felt
    like. [¶] . . . [¶] . . . Something like in a previous livelihood
    specting [sic] him reincarnated, someone getting reincarnated
    in a certain fashion. It would never work, say for instance,
    70
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Adol[f] Hitler, he would never want to come back to life. But
    people would want him to come back to life, so people would have
    to use certain individuals.” In another instance, when asked
    about what kinds of problems he reported having to the County
    Mental Health Hospital (CMH) a few months after the chili
    incident, Baker replied: “It put me in a state of mind like they
    wanted my backbone for this. It started off like as a quote of a
    price, like it started off at $35,000. And as my ride went into
    CMH, after sedation you could hear they were going for like a
    bid. But it was like a music box going off. You know, it was
    premeditated. So I just went along with it. The highest price
    was like 87 million dollars. I just went with it.”
    As Flinner points out, the jury also heard Baker’s testimony
    that he had used methamphetamine a few days before the
    evening at Flinner’s house, as well as Baker’s testimony about
    his broader past drug usage and mental health issues, including
    “delusions” that caused him to check into CMH a few months
    after the evening in question. The jury was presented with
    evidence that Baker tested positive for methamphetamine,
    THC, and Xanax after being taken from Flinner’s apartment to
    the sheriff’s substation. And the jury heard the expert
    testimony of a psychiatrist, who reviewed Baker’s medical
    records from his time at CMH and testified that Baker was
    “having a very severe problem with psychosis, with
    hallucinations and psychotic delusions” and who conveyed his
    expert opinion that such a person’s “ability to accurately
    perceive what’s going on in the real word [sic] is severely
    impaired.”
    But “ ‘[t]he fact that a witness has made inconsistent and
    exaggerated statements does not indicate an inability to
    perceive [or] recollect . . . .’ [Citation.] Nor does a witness’s
    71
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    mental defect or insane delusions necessarily reflect that the
    witness lacks the capacity to perceive or recollect.” (People v.
    
    Lewis, supra
    , 26 Cal.4th at p. 356.) Despite these isolated
    digressions, Baker was consistently brought back to the relevant
    events by the prosecutor’s and defense counsel’s questioning.
    He was able to testify coherently about his work for Flinner’s
    landscaping business, about how Flinner invited him to dinner
    and offered him a bowl of chili, that Flinner also ordered a pizza
    for himself and did not have any of the chili, and about how he
    became drowsy five to 10 minutes after he ate the bowl of chili.
    He recalled being awoken in the early hours of the morning by
    sheriff’s deputies who were responding to a complaint that he
    had been running around the pool and yelling and related how
    he was taken to the sheriff’s substation to have his blood drawn
    and urine sample taken. Thus, “[a]lthough [Baker’s] testimony
    may have consisted of inconsistencies, incoherent responses,
    and possible hallucinations, delusions and confabulations,” he
    “ ‘presented a plausible account’ ” of his relationship with
    Flinner and the evening’s events. (Lewis, at p. 357; see
    
    Anderson, supra
    , 25 Cal.4th at pp. 574–575 [trial court properly
    allowed witness’s testimony about murder despite her delusion
    that her imaginary son was present at the murder].) Nor were
    the deficiencies in Baker’s capabilities as a witness hidden from
    the jury, which was given an “ample basis upon which to judge
    the reliability of [Baker’s] observations.” (Anderson, at p. 575.)
    In sum, the trial court did not err in permitting Baker to
    testify or in failing to strike his testimony on these matters. We
    reject Flinner’s argument to the contrary and his related
    constitutional claims.
    72
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    7. Admissibility of Portions of Codefendant’s
    Confession to Police
    Flinner contends that the trial court erred in admitting
    portions of his codefendant Ontiveros’s confession to police and
    that the admission of these statements violated his
    confrontation clause rights under the Sixth and Fourteenth
    Amendments to the United States Constitution. We agree there
    was error but conclude that it was harmless beyond a reasonable
    doubt.
    Before trial, the prosecution conceded that two juries were
    appropriate in this case but sought to establish that certain
    parts of Ontiveros’s confession to police would be admissible
    before Flinner’s jury. Flinner moved in limine to exclude all of
    Ontiveros’s statements to police as inadmissible hearsay whose
    admission would violate Flinner’s confrontation clause rights.
    The trial court determined that certain portions of Ontiveros’s
    confession that inculpated Ontiveros alone and did not explicitly
    or implicitly refer to Flinner were sufficiently trustworthy to be
    admitted against Flinner as statements against the declarant’s
    interest.
    At trial, Ontiveros did not testify. With only Flinner’s jury
    present, the prosecution offered the approved statements
    against interest through Detective Scully, who interviewed
    Ontiveros after his arrest. To ensure that the jury heard only
    the narrow, approved statements from Ontiveros’s confession,
    the prosecutor read verbatim portions of the interview
    transcript and asked Detective Scully whether the answers in
    the transcript were the ones that Ontiveros gave him. By this
    means, the prosecutor introduced Ontiveros’s admissions that
    on the day of Keck’s killing he was driving the white Nissan NX
    car by himself, and that Keck picked him up, drove him to the
    73
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    cul-de-sac, and parked her car facing the Nissan in the cul-de-
    sac.
    After the jury returned the guilt verdicts but before
    sentencing, the high court issued its decision in 
    Crawford, supra
    , 
    541 U.S. 36
    , where it held that the admission of
    testimonial hearsay statements against a criminal defendant
    violates the confrontation clause unless the witness is
    unavailable and the defendant had a prior opportunity for cross-
    examination. Flinner moved for a new trial, arguing that
    Ontiveros’s statements were inadmissible against Flinner under
    Crawford. The trial court agreed that the admission of
    Ontiveros’s statements fell afoul of Crawford but ruled that
    their admission was subject to harmless error review under
    Chapman v. California (1967) 
    386 U.S. 18
    , and was harmless
    beyond a reasonable doubt. It accordingly denied Flinner’s
    motion for a new trial.
    Flinner renews his trial arguments that the introduction
    of Ontiveros’s statements through Detective Scully’s testimony
    violated the confrontation clause under Crawford and that the
    error necessitates a new trial. The Attorney General responds
    that Ontiveros’s statements are admissible under pre-Crawford
    case law concerning the introduction of a codefendant’s
    confession in a joint trial — namely, 
    Bruton, supra
    , 
    391 U.S. 123
    , and Richardson v. Marsh (1987) 
    481 U.S. 200
    (Richardson).
    And he argues that Crawford does not bar the admission of
    Ontiveros’s statements because Ontiveros’s statements neither
    accused Flinner of anything nor mentioned the involvement of
    anyone other than Ontiveros in Keck’s murder.
    The Attorney General’s reliance on Bruton and
    Richardson is misplaced. “In Bruton, the United States
    74
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Supreme Court held that the admission into evidence at a joint
    trial of a nontestifying codefendant’s confession implicating the
    defendant violates the defendant’s right to cross-examination
    guaranteed by the confrontation clause, even if the jury is
    instructed to disregard the confession in determining the guilt
    or innocence of the defendant. [Citation.] The high court
    reasoned that although juries ordinarily can and will follow a
    judge’s instructions to disregard inadmissible evidence, ‘there
    are some contexts in which the risk that the jury will not, or
    cannot, follow instructions is so great, and the consequences of
    failure so vital to the defendant, that the practical and human
    limitations of the jury system cannot be ignored.’ [Citation.]
    Such a context is presented when ‘the powerfully incriminating
    extrajudicial statements of a codefendant, who stands accused
    side-by-side with the defendant, are deliberately spread before
    the jury in a joint trial.’ ” (People v. Lewis (2008) 
    43 Cal. 4th 415
    ,
    453 (Lewis).) As we explained in Lewis, “[t]he high court limited
    the scope of the Bruton rule in Richardson . . . . The court
    explained that Bruton recognized a narrow exception to the
    general rule that juries are presumed to follow limiting
    instructions, and this narrow exception should not apply to
    confessions that are not incriminating on their face, but become
    so only when linked with other evidence introduced at trial.
    [Citation.] That is because, ‘[w]here the necessity of such
    linkage is involved, it is a less valid generalization that the jury
    will not likely obey the instruction to disregard the evidence.’
    [Citation.] Accordingly, the high court held, ‘the Confrontation
    Clause is not violated by the admission of a nontestifying
    codefendant’s confession with a proper limiting instruction
    when . . . the confession is redacted to eliminate not only the
    75
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    defendant’s name, but any reference to his or her existence.’ ”
    (Lewis, at p. 454, italics omitted.)
    The Attorney General argues that under Richardson,
    Ontiveros’s statements were admissible because nothing in
    Ontiveros’s statements expressly inculpates Flinner. But the
    codefendants in Bruton and Richardson, unlike those here, were
    jointly tried in a case before a single jury, and both cases rested
    on the premise that the nontestifying defendant’s confession
    was inadmissible against the codefendant. In each case, the
    trial court imposed a limiting instruction to the jury that it could
    only consider the confession as evidence against the declarant
    and not against the codefendant. (See 
    Bruton, supra
    , 391 U.S.
    at p. 125; 
    Richardson, supra
    , 481 U.S. at pp. 204–205.) The high
    court had to decide whether the limiting instruction sufficed to
    protect the codefendant’s confrontation rights. In other words,
    the question in these cases was not whether a nontestifying
    defendant’s confession is admissible against his codefendant;
    the opinions assumed that it was not. The question, instead,
    was whether — given that the defendant’s confession was only
    admissible against him and not his codefendant — a limiting
    instruction by the court is sufficient to protect the codefendant’s
    confrontation rights. Here, Flinner and Ontiveros were jointly
    tried but before two separate juries. No limiting instruction was
    given — indeed, the relevant testimony by Detective Scully was
    offered only to Flinner’s jury — because the trial court expressly
    determined that Ontiveros’s statements were admissible
    against Flinner as statements against interest. For these
    reasons, Bruton and Richardson are simply irrelevant here.
    (See also People v. Brown (2003) 
    31 Cal. 4th 518
    , 537 [Bruton
    rule inapplicable where defendants are not jointly tried].)
    76
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    The Attorney General’s Crawford argument fares no
    better. Crawford held that the admission of testimonial hearsay
    statements violates a criminal defendant’s confrontation rights
    unless the declarant is unavailable, and the defendant had a
    prior opportunity to cross-examine the declarant. (
    Crawford, supra
    , 541 U.S. at p. 68.) Because Ontiveros invoked his right
    not to testify and Flinner had no prior opportunity to cross-
    examine him, the introduction of Ontiveros’s statements to
    Detective Scully violated the confrontation clause if those
    statements are “testimonial.” In Crawford, the high court held
    that “[w]hatever else th[at] term covers, it applies at a minimum
    to prior testimony at a preliminary hearing, before a grand jury,
    or at a former trial; and to police interrogations,” for these are
    “the modern practices with closest kinship to the abuses at
    which the Confrontation Clause was directed.” (Crawford, at
    p. 68, italics added.) Here, the statements the trial court
    admitted are ones that Ontiveros made after his arrest, while in
    custody, in response to questioning by Detective Scully, and as
    part of his confession to playing a role in Keck’s murder. There
    can be no doubt that these statements are testimonial, and the
    Attorney General does not seriously contend otherwise.
    The Attorney General argues instead that the “chief evil”
    that Crawford sought to prevent is the introduction of
    “accusatory testimonial statements.”      Because Ontiveros’s
    statements did not explicitly or implicitly accuse Flinner of
    anything, the Attorney General reasons that Flinner’s
    confrontation rights were not implicated by their admission.
    But the high court has already rejected a similar argument. In
    Melendez-Diaz v. Massachusetts (2009) 
    557 U.S. 305
    , the high
    court concluded that the affidavits of crime lab analysts
    certifying that a substance found in the defendant’s possession
    77
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    was cocaine “were testimonial statements” and that “the
    analysts were ‘witnesses’ for purposes of the Sixth Amendment.”
    (Melendez-Diaz, at p. 311.) In so doing, the high court rejected
    Massachusetts’ argument that “the analysts are not subject to
    confrontation because they are not ‘accusatory’ witnesses, in
    that they do not directly accuse petitioner of wrongdoing; rather,
    their testimony is inculpatory only when taken together with
    other evidence linking petitioner to the contraband.” (Id. at
    p. 313.) The court rejected this distinction between accusatory
    and nonaccusatory witnesses:           “The text of the [Sixth]
    Amendment contemplates two classes of witnesses — those
    against the defendant and those in his favor. . . . Contrary to
    respondent’s assertion, there is not a third category of
    witnesses, helpful to the prosecution, but somehow immune
    from confrontation.”          (Melendez-Diaz, at pp. 313–314.)
    Similarly, in Williams v. Illinois (2012) 
    567 U.S. 50
    , 135, a
    majority of the court rejected the plurality’s reasoning that a
    statement must be “ ‘prepared for the primary purpose of
    accusing a targeted individual’ ” in order to be testimonial,
    pointing to the high court’s reasoning in Melendez-Diaz.
    (Williams, at p. 135 (dis. opn. of Kagan, J.), quoting
    id. at p. 84
    (plur. opn. of Alito, J.); accord, U.S. v. Duron-Caldera (5th Cir.
    2013) 
    737 F.3d 988
    , 994–996.)
    We conclude the Attorney General’s argument fails for the
    same reason. The prosecution offered the approved portions of
    Ontiveros’s confession before Flinner’s jury out of the presence
    of Ontiveros’s jury, presumably because these statements
    corroborated the prosecution’s theory that Flinner had hired
    Ontiveros to kill Keck. The fact that the selected statements do
    not explicitly mention Flinner does not render Ontiveros any
    78
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    less a “witness[] against” Flinner within the meaning of the
    Sixth Amendment.
    The Attorney General suggests we have held otherwise in
    People v. Stevens (2007) 
    41 Cal. 4th 182
    and 
    Lewis, supra
    , 
    43 Cal. 4th 415
    , where we reasoned that “[t]he same redaction that
    ‘prevents Bruton error also serves to prevent Crawford error.’ ”
    (Stevens, at p. 199; accord, Lewis, at p. 506.) But as with Bruton
    and Richardson, Stevens and Lewis have no application here:
    Both concerned the admission of a codefendant’s statement at a
    joint trial before a single jury. The codefendant in Stevens also
    testified at the joint trial and was thus available for cross-
    examination, obviating any confrontation clause problem.
    (Stevens, at p. 199.)
    In Lewis, redacted portions of the codefendant’s confession
    to police were read to the jury and the “jury was instructed to
    consider these statements against the speaker only and not
    against any other defendant.” (
    Lewis, supra
    , 43 Cal.4th at
    p. 452.) Although we agreed with the defendant that the
    admitted statements from his codefendant’s confession were “no
    doubt testimonial,” we reasoned that the statements were not
    admitted “against” the defendant within the meaning of the
    confrontation clause because they did not facially implicate the
    defendant. (Id. at p. 506.) We noted: “As the high court has
    explained, ‘[o]rdinarily, a witness whose testimony is introduced
    at a joint trial is not considered to be a witness “against” a
    defendant if the jury is instructed to consider that testimony
    only against a codefendant.’ [Citation.] The only exception to
    this rule is the narrow class of statements . . . that powerfully
    incriminate the defendant on their face because they directly
    implicate the defendant by name or do so in a manner the jury
    could not reasonably be expected to ignore. [Citations.]
    79
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Accordingly, redacted codefendant statements that satisfy
    Bruton’s requirements are not admitted ‘against’ the defendant
    for Crawford purposes.” (Lewis, at p. 506.) By contrast, as we
    have already explained, Ontiveros’s statements were expressly
    admitted against Flinner.
    For these reasons, we agree with the trial court that the
    admission of Ontiveros’s statements against Flinner violated
    Flinner’s confrontation clause rights. The question remains,
    however, whether the error was harmless beyond a reasonable
    doubt. (See Lilly v. Virginia (1999) 
    527 U.S. 116
    , 139–140.) On
    this question, too, we agree with the trial court. Nothing elicited
    from Ontiveros directly implicated Flinner, whose involvement
    in the scheme to kill Keck was proven by independent evidence.
    And even as to the manner in which Ontiveros implemented the
    final phase of that scheme, the killing itself, other evidence
    illuminated most of the details: Photos and videos from nearby
    surveillance cameras showed Keck’s and Ontiveros’s
    movements into and (in Ontiveros’s case) out of the cul-de-sac,
    and the crime scene and forensic evidence showed Keck was shot
    in the back of her head while opening the hood of her car, which
    was still running. As we conclude in the next discussion section,
    there was ample evidence, independent of Ontiveros’s
    statement, that he accompanied Keck to the cul-de-sac and
    waited until she was occupied opening her hood before shooting
    her in the back of the head. As to both first degree murder and
    the lying-in-wait special circumstance, therefore, Ontiveros’s
    statement that Keck drove him to the cul-de-sac and parked her
    car facing his was cumulative of other prosecution evidence
    regarding the manner of Keck’s killing. For that reason, and
    because the portion of Ontiveros’s statement admitted in
    80
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Flinner’s trial did not directly inculpate Flinner, its admission
    was harmless beyond a reasonable doubt.
    8. Sufficiency of the Evidence for the Lying-in-Wait
    Special-Circumstance Finding and the Lying-in-
    Wait First Degree Murder Conviction
    Flinner contends there was insufficient evidence to
    support his conviction for lying-in-wait first degree murder, as
    well as insufficient evidence to support the lying-in-wait special-
    circumstance finding.
    “We often address claims of insufficient evidence, and the
    standard of review is settled. ‘A reviewing court faced with such
    a claim determines “whether, after viewing the evidence in the
    light most favorable to the prosecution, any rational trier of fact
    could have found the essential elements of the crime beyond a
    reasonable doubt.” [Citations.] We examine the record to
    determine “whether it shows evidence that is reasonable,
    credible and of solid value from which a rational trier of fact
    could find the defendant guilty beyond a reasonable doubt.”
    [Citation.] Further, “the appellate court presumes in support of
    the judgment the existence of every fact the trier could
    reasonably deduce from the evidence.” ’ ” (People v. Moon (2005)
    
    37 Cal. 4th 1
    , 22.)
    The capital murder in this case occurred in June 2000,
    shortly after Proposition 18 amended the lying-in-wait special-
    circumstance statute. (Stats. 1998, ch. 629, § 2, pp. 4163–4166,
    enacted as Prop. 18, approved by voters, Primary Elec. (Mar. 7,
    2000) eff. Mar. 8, 2000.) We consider the effect of that
    amendment below (pt. II.B.9., post), in addressing Flinner’s
    argument that the amendment rendered the special
    circumstance unconstitutional. As relevant here, however,
    81
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    “[l]ike the former version, the amended lying-in-wait special
    circumstance requires ‘ “ ‘an intentional murder, committed
    under circumstances which include (1) a concealment of
    purpose, (2) a substantial period of watching and waiting for an
    opportune time to act, and (3) . . . a surprise attack on an
    unsuspecting victim from a position of advantage . . . .’ ” ’ ”
    (People v. Johnson (2016) 
    62 Cal. 4th 600
    , 629 (Johnson).) The
    lying-in-wait special circumstance (Pen. Code, § 190.2, subd.
    (a)(15)) includes the elements of first degree lying-in-wait
    murder (id., § 189, subd. (a)), but requires the additional
    element that the killing was intentional, not merely committed
    with implied malice. (See, e.g., People v. 
    Moon, supra
    , 37 Cal.4th
    at p. 24, fn. 1.) Thus, we focus here on whether substantial
    evidence supports the special circumstance, for if it does, it
    necessarily supports the theory of first degree lying-in-wait
    murder. (See, e.g., People v. Carpenter (1997) 
    15 Cal. 4th 312
    ,
    388.)
    Flinner concedes that the concealment element of the
    statute is satisfied here, where Flinner and Ontiveros concealed
    their purpose from Keck when they summoned her to the cul-
    de-sac on the pretense of jumpstarting Ontiveros’s car. And
    Flinner does not argue that he or Ontiveros lacked the intent to
    kill. But Flinner maintains that the evidence was insufficient
    to establish a “substantial period of watching and waiting” and
    a “surprise attack from a position of advantage.”
    First, Flinner contends that the mere three minutes that
    elapsed between the time Keck’s Mustang entered the cul-de-sac
    to the time Ontiveros drove away from the scene of the murder
    could not constitute a substantial period of watching and
    waiting. But as we have repeatedly explained, the purpose of
    the watching and waiting element “ ‘ “is to distinguish those
    82
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    cases in which a defendant acts insidiously from those in which
    he acts out of rash impulse. [Citation.] This period need not
    continue for any particular length ‘ “of time provided that its
    duration is such as to show a state of mind equivalent to
    premeditation or deliberation.” ’ ” ’ ” (People v. Cage (2015) 
    62 Cal. 4th 256
    , 278.)
    Here, viewing the evidence in the light most favorable to
    the verdicts, we conclude that the prosecution presented
    sufficient admissible evidence from which a trier of fact could
    find beyond a reasonable doubt that Ontiveros watched and
    waited for an opportune moment to launch a surprise attack on
    Keck. The prosecution’s theory of the murder was that Flinner
    called Keck and asked her to pick up Ontiveros from a nearby
    gas station and drive to a cul-de-sac where Ontiveros’s car had
    broken down in order to give him a jumpstart. While Keck was
    facing her Mustang and opening its hood, Ontiveros shot her in
    the back of the head. The prosecution’s evidence of how the
    actual killing occurred consisted largely of surveillance videos
    and stills from gas stations, stores, and businesses in the area,
    as well as forensic evidence of Keck’s injuries and the state in
    which her car was found at the crime scene.13 Video shows
    13
    As we have explained, the trial court erred in admitting
    portions of codefendant Ontiveros’s custodial confession. (See
    pt. II.B.7., ante.) Due to that error, the jury heard Ontiveros’s
    statements that he drove the white Nissan NX car on the day of
    the murder and was alone in the car that day, that Keck picked
    him up and drove him to the cul-de-sac, and that Keck parked
    her car nose-to-nose with the Nissan in the cul-de-sac. Our past
    case law suggests that it would not be improper to consider these
    statements in assessing Flinner’s sufficiency-of-the-evidence
    claim. (See People v. Shirley (1982) 
    31 Cal. 3d 18
    , 70–71.) But
    83
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Keck’s Mustang leaving the Ultramar station where she met
    Ontiveros and then heading towards the cul-de-sac road.
    Approximately three minutes and 15 seconds after her white
    Mustang enters the cul-de-sac, video shows the Nissan NX
    speeding out of it.
    Deputy Sheriff Troy Doran testified that Keck’s Mustang
    was found with the keys still in the car, the engine running, and
    the passenger door open. Photos of the crime scene showed that
    the hood of Keck’s Mustang was ajar, though not propped open
    with the hood rod. And photos showed blood stains on the front
    bumper of the car, the underside of the hood, and on the hood
    rod, which was out of place. Robert Whitmore, who performed
    the autopsy, testified that he found a “textbook entrance wound”
    on the back of Keck’s head, and that the lack of soot on the
    wound indicated that the gun was some distance away from her
    head when it was fired. He also testified that Keck sustained
    facial abrasions before she died, which he opined were
    consistent with her face hitting the engine compartment of the
    Mustang after she was shot. And he testified that he found no
    evidence of evasion by Keck, suggesting that she never saw the
    gunshot coming. The bullet thus passed through Keck’s brain,
    exited through her right cheek, and finally lodged in the firewall
    of her car in the engine compartment. David Cornacchia, a blood
    spatter expert, testified that blood on Keck’s leg and on the
    engine of the car were consistent with Keck being shot while
    holding open the hood and leaning over the engine. And even
    before the autopsy was performed, at a point when the
    even without Ontiveros’s confession, sufficient evidence
    supports the lying-in-wait special circumstance, and we do not
    rely on that confession here.
    84
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    pathologist at the scene of the crime could not determine
    whether Keck had been shot in the back of the head or in the
    face, Flinner told witness Robert Pittman that Keck had been
    shot in the back of the head. In light of this substantial
    evidence, a reasonable jury could conclude that Ontiveros
    watched and waited at the cul-de-sac for the opportune moment
    to shoot Keck from behind: when Keck was facing her Mustang
    in order to lift the hood of the car to provide a jump start.
    Flinner also argues that there is insufficient evidence that
    Ontiveros shot Keck from a position of advantage. He reasons
    that the fact that Keck was shot in the back of the head “does
    nothing to distinguish this case from any other such ‘ordinary
    premeditated murder,’ ” quoting our decision in People v.
    Morales (1989) 
    48 Cal. 3d 527
    , 557. As we explained in Morales,
    “a mere concealment of purpose” is not sufficient to establish
    lying in wait, since “many ‘routine’ murders are accomplished
    by such means, and . . . constitutional considerations . . . might
    well prevent treating the commission of such murders as a
    special circumstance.” (Ibid.) Were there only evidence
    suggesting, for example, that Ontiveros drove up behind Keck
    while she had the hood of her car open and shot her from behind,
    we might agree with Flinner that the evidence could not
    distinguish the killing from an ordinary premediated murder
    not subject to a lying-in-wait special-circumstance finding. (Cf.
    People v. Nelson (2016) 
    1 Cal. 5th 513
    , 551 [insufficient evidence
    for lying-in-wait special circumstance where evidence only
    showed the defendant “came up behind his victims on foot to
    take them by surprise” and no evidence showed that he “arrived
    before the victims or waited in ambush for their arrival”].) But
    here, as discussed above, the evidence tends to show that
    Ontiveros left the Nissan NX in the cul-de-sac in advance of
    85
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Keck’s arrival, waited for Keck at the gas station, and drove with
    her back to the cul-de-sac. The evidence further shows that
    Keck was shot while facing her car and opening the hood. In
    light of this evidence, a jury could reasonably conclude that
    Ontiveros “ ‘ “ ‘watch[ed] and wait[ed] for an opportune time to
    act’ ” ’ ” on the drive from the gas station to the cul-de-sac, while
    Keck parked and got out of the car, and while she proceeded to
    open the hood of the car, before launching “ ‘ “ ‘a surprise
    attack’ ” ’ ” on Keck from an advantageous position: from behind
    her as she was otherwise preoccupied with opening the hood.

    , 62 Cal.4th at p. 629.)
    9. Constitutionality of Lying-in-Wait Special
    Circumstance
    Flinner argues that Proposition 18 rendered the lying-in-
    wait special circumstance indistinguishable from lying-in-wait
    first degree murder, and that the special circumstance is
    therefore unconstitutionally vague and fails to adequately
    narrow the class of death-eligible defendants, creating an
    arbitrary and capricious application of the death penalty in
    violation of the Eighth and Fourteenth Amendments. We
    recently rejected this argument in 
    Johnson, supra
    , 62 Cal.4th at
    pages 634 to 637, and Flinner offers no reason to reconsider that
    decision here.
    “In assessing defendant’s challenge to the amended lying-
    in-wait special circumstance, we are guided by the following
    constitutional principles.       The Eighth and Fourteenth
    Amendments prohibit a sentence of death ‘imposed under
    sentencing procedures that create a substantial risk that the
    punishment will be inflicted in an arbitrary and capricious
    manner.’ [Citation.] To satisfy this constitutional command,
    ‘the trier of fact must convict the defendant of murder and find
    86
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    one “aggravating circumstance” (or its equivalent) at either the
    guilt or penalty phase. [Citations.] . . . [T]he aggravating
    circumstance must meet two requirements. First, the
    circumstance may not apply to every defendant convicted of a
    murder; it must apply only to a subclass of defendants convicted
    of murder. [Citation.] Second, the aggravating circumstance
    may not be unconstitutionally vague.’ [Citation.] The lying-in-
    wait special circumstance is an ‘aggravating circumstance[]’
    subject to these constitutional requirements.” 
    (Johnson, supra
    ,
    62 Cal.4th at pp. 634–635.)
    As we explained in Johnson, “in March 2000, the voters
    passed Proposition 18, which changed the definition of the lying-
    in-wait special circumstance from a killing while lying in wait to
    a killing by means of lying in wait, mirroring the language of the
    first degree murder statute.” 
    (Johnson, supra
    , 62 Cal.4th at
    p. 634.) “[T]he voters’ purpose in amending the lying-in-wait
    special circumstance was to eliminate the temporal distinction
    between the special circumstance and lying-in-wait first degree
    murder . . . thereby expand[ing] the class of cases in which the
    special circumstance could be found true . . . .” (Id. at p. 636.)
    Nevertheless, we concluded that the amended lying-in-wait
    special circumstance comports with the Eighth Amendment
    because it “adequately distinguishes itself from other murders
    and does so in terms that are not so vague as to permit arbitrary
    determinations regarding the truth of the special circumstance
    allegation.” (Johnson, at p. 636.) As we have long held, the
    “factual matrix” presented by the lying-in-wait special
    circumstance — an intentional murder coupled with the
    elements of concealment, watching and waiting, and a surprise
    attack from a position of advantage — sufficiently distinguish it
    from “ ‘ordinary’ premeditated murder” (People v. Morales,
    87
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, 
    J. supra
    , 48 Cal.3d at p. 557), such that it is “neither applicable to
    all murderers nor impermissibly vague” (Johnson, at p. 636).
    And, in Johnson, we reasoned that even if Proposition 18 had
    rendered the special circumstance identical to lying-in-wait first
    degree murder, the special circumstance would pass
    constitutional    scrutiny    because     lying-in-wait    murder
    “historically has been viewed as ‘ “a particularly heinous and
    repugnant crime,” ’ ” which “provides ‘a rational basis for
    distinguishing those murderers who deserve to be considered for
    the death penalty from those who do not.’ ” (Johnson, at p. 637.)
    Johnson      likewise    forecloses  Flinner’s    as-applied
    constitutional challenge to the special circumstance. Like the
    defendant in Johnson, Flinner here contends that “because his
    liability for lying-in-wait first degree murder as an aider and
    abettor required a showing of intent to kill, there was no
    meaningful distinction between that theory of first degree
    murder and the lying-in-wait special circumstance in his case.”
    
    (Johnson, supra
    , 62 Cal.4th at p. 637.) This “is simply another
    way to state his facial attack on the statute” (
    Lewis, supra
    , 43
    Cal.4th at p. 517), which we have rejected in part because —
    even were the special circumstance identical to the lying-in-wait
    first degree murder statute, as Flinner claims it is as applied to
    him in this case — it would not offend the Constitution.
    10. Juror Misconduct
    Based on information received from jurors after the penalty
    verdict was returned, Flinner moved for a new trial, alleging
    several instances of juror misconduct. The trial court held a
    multiday evidentiary hearing, at which numerous jurors
    testified, and denied the motion on the ground that no
    misconduct had occurred. On appeal, Flinner contends the
    88
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    evidence showed reversible misconduct on the parts of Jurors
    No. 1 and No. 10. We review the factual background and
    hearing evidence before considering both these aspects of the
    misconduct claim.
    During trial, defendant Flinner’s jury was sometimes
    referred to as the “Red” jury and codefendant Ontiveros’s as the
    “Green” jury. In December 2003, after both juries had returned
    their penalty verdicts and had been excused, the trial court
    received an e-mail message from two members of the Green jury
    relaying assertions by Red Juror No. 1 about misconduct by Red
    Jurors No. 10 and No. 12.14 The messages also revealed that
    Juror No. 1 was interested in writing a book about the trial or
    her experiences as a juror and had been enlisting others in a
    possible group writing effort. The court provided the parties
    printouts of the e-mails in early January 2004.            After
    investigation, Flinner filed a memorandum in support of his new
    trial motion alleging several instances of misconduct by Juror
    No. 1, Juror No. 10 and unspecified other jurors. The court set
    the matter for an evidentiary hearing in March 2004.
    At the hearing, Juror No. 1 testified to the personal conflicts
    between her and Jurors No. 10 and No. 12 arising from what she
    saw as those jurors’ misconduct. Throughout the trial, Juror
    No. 1 asserted, Jurors No. 10 and No. 12 acted in a
    “manipulative” manner, “attempt[ing] on a daily basis to swing
    the other[,] older women over to their way of thinking.” During
    breaks in the courthouse hallway and cafeteria, they gave their
    opinion about the evidence the jury had just heard and, when
    anyone voiced a different view, “we were told how wrong we
    14
    Red jurors will hereafter be identified by their numbers
    alone; Green jurors will be identified as such.
    89
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    were.” By the time of deliberations, “[t]hose two girls had [the
    older women] wrapped up. They knew that they were going to
    get a guilty verdict out of them.”
    Jurors No. 10 and No. 12 also put together a weekly
    invitational lunch group that eventually grew to include most of
    the jury. Juror No. 1 testified she was never invited but did not
    feel slighted because she knew that the group discussed the case
    over lunch and she did not want to violate the court’s admonition
    against such discussions. After a while during the trial, the
    group around Jurors No. 10 and No. 12 would stop talking
    whenever Juror No. 1 approached them; Juror No. 1 understood
    that to be because they knew that she was taking notes on what
    they said and “they were talking about things they shouldn’t be.”
    Juror No. 1 testified she twice overheard Juror No. 10 say
    she had driven past the home of Flinner’s parents on Harbison
    Canyon Road. The second time occurred after the wildfires in
    San Diego County in the fall of 2003; Juror No. 10 said she had
    to travel that road in order to visit relatives in the area.
    Juror No. 1 also testified to remarks by Juror No. 10
    suggesting a prosecution bias on her part. Juror No. 10
    sometimes wore tight blouses and short skirts. Once, when
    Juror No. 1 and others told her the buttons on her blouse had
    popped open, she said she did not care, that she wanted her
    blouse open so that Flinner would look at her and she could tell
    him that she wanted him dead. Later in her testimony, Juror
    No. 1 said she actually observed Juror No. 10 mouthing “I want
    to kill you,” or “I want you dead,” at Flinner. “Many times
    during side bars, many times I would turn around,” Juror No. 1
    testified, “and [Juror No. 10] would be doing it and . . . [h]er and
    12 would be giggling about it.” Still later, Juror No. 1 testified
    90
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    she only saw Juror No. 10 do this once, though she also saw her
    making throat cutting gestures at times, usually during a side
    bar. Juror No. 1 also testified to hearing Juror No. 10 refer to
    the lead police investigator, Detective Scully, as “our detective”
    and comment to other jurors on his “cute . . . rear end.”
    The tensions between Jurors No. 1 and No. 10 came to a
    head during guilt phase deliberations, when Juror No. 1 saw
    Juror No. 10 conferring privately with the foreperson. In what
    Juror No. 1 described as a “blowup,” she confronted them, and
    they said they had been strategizing about how to sway a
    holdout juror.
    At the evidentiary hearing, Juror No. 1 acknowledged she
    had planned to write a book about her experience as a juror in a
    capital case. She kept extensive notes during the trial, in part
    with the book prospect in mind. She testified that she did not
    attempt to find a means of publication until after the trial, when
    she explored “tools on the internet that will allow you to do self-
    publishing with their assistance.” She also testified, however,
    that in September 2003, during the trial, she e-mailed a self-
    publishing service about the possibility of a loan, giving them an
    estimate of January 2004 as the date she would be ready to
    discuss further steps. She received a positive response from the
    company (her testimony was unclear as to the date), but she
    never actually received any money.
    After the trial, Juror No. 1 began drafting a book and
    discussed the idea with former Green jurors. But in January, a
    stranger in a mall parking lot approached her and threatened
    unspecified harm if she kept “testifying.” This threat, together
    with some unexplained events at her home (hang-up telephone
    91
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    calls and banging on her door at night) prompted her to abandon
    the book project and destroy her notes and draft.
    Some of Juror No. 1’s assertions were corroborated by other
    jurors. Jurors No. 10 and No. 12 admitted that during the trial
    breaks they joked about Detective Scully having a nice butt.
    Juror No. 3 and members of the Green jury corroborated Juror
    No. 1’s testimony that Juror No. 10 sometimes wore short skirts
    and tight blouses. Green Juror No. 11 testified to seeing Juror
    No. 10 use a water bottle to mime oral sex during a court
    session, and Green Juror No. 10 testified that Juror No. 10
    parted her legs so that Detective Scully could see up her skirt.
    On cross-examination, though, Green Juror No. 10 admitted he
    could not actually see up Juror No. 10’s skirt and did not know
    whether Detective Scully could.
    Generally, however, Juror No. 1’s assertions of misconduct
    by her fellow jurors were not corroborated. Jurors No. 10 and
    No. 12 denied discussing the evidence at breaks or lunch during
    the trial; when they did talk about witnesses who had appeared,
    it was only to comment on their dress or speculate on how long
    they would testify. Other jurors agreed the hallway and lunch
    conversations did not involve the evidence, though Juror No. 7
    recalled one occasion, early in the trial, when she began to talk
    about a witness in the hallway but stopped when Juror No. 1
    reminded her of the admonition. Juror No. 10 denied having
    ever attempted to communicate with Flinner across the
    courtroom, and no other juror corroborated Juror No. 1’s
    account. Juror No. 10 also denied having deliberately parted
    her legs in the direction of Detective Scully or anyone else in the
    courtroom or having made any sexual gesture with her water
    bottle. Juror No. 10 also denied having deliberately visited the
    92
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    home of Flinner’s parents; she had to drive on their road to reach
    her children during the fire emergency.
    The trial court denied Flinner’s new trial motion on factual
    grounds. Were Juror No. 1’s assertions of misconduct correct,
    the court opined, Flinner would be entitled to a new trial. But
    those misconduct claims were “[a]lmost in their entirety . . .
    rejected, countered, rebutted and/or innocently explained by the
    rest of the jurors.” The court concluded Juror No. 1’s antipathy
    for Juror No. 10, and her desire for the spotlight, had led her to
    engage in “grandiosity, puffery, hyperbole, gross exaggeration,
    speculation, flights of fancy, unsupported assumptions” and,
    where there was no more innocent explanation, “outright
    fabrication to further her own personal agenda.” The court
    based its credibility determination on the hearing evidence and
    the court’s observations of the jury during trial. Had there been
    juror misconduct as frequent and severe as Juror No. 1 had
    asserted, “it would not and it could not have escaped notice by
    the court, court personnel, counsel for the parties and the
    spectators.” There had been “isolated violations” by the jurors
    of the court’s admonitions, the court concluded, but none of a
    nature that “singly or in combination” substantially prejudiced
    the trial’s fairness.
    a. Asserted Misconduct by Juror No. 1
    Jury misconduct serious and extensive enough to impair the
    fairness of the trial or deliberations may warrant granting a new
    trial motion. (Pen. Code, § 1181, subd. 3; People v. Collins (2010)
    
    49 Cal. 4th 175
    , 242.) Where the trial court has heard evidence
    and made findings of historical fact regarding the alleged
    misconduct, we accept those findings if they are supported by
    substantial evidence. (People v. Weatherton (2014) 
    59 Cal. 4th 93
                            PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    589, 598; People v. Pride (1992) 
    3 Cal. 4th 195
    , 260.) Whether
    those facts constitute misconduct is, however, a legal question
    we review independently. (Collins, at p. 242.)
    Flinner contends Juror No. 1’s exaggerations and
    fabrications about her fellow jurors, viewed in the context of her
    plan to write a book about her jury experience, demonstrate a
    bias on her part. Her efforts to make her contemplated book
    more “entertaining,” he argues, show that “her literary project
    compromised her objectivity.” Moreover, Juror No. 1’s lack of
    credibility, Flinner maintains, shows she misconducted herself
    in deliberations: “She exaggerated various claims of juror
    misconduct, and for the same reason would likely have
    exaggerated the evidence.” Finally, in a later section of his brief,
    Flinner argues alternatively that: (a) Juror No. 10 committed
    misconduct, as Juror No. 1 asserted; but (b) “if this court accepts
    the trial court’s factual finding that Juror No. 1 fabricated her
    testimony, it must reverse because of Juror No. 1’s perjury.”
    We accept the trial court’s findings regarding Juror No. 1’s
    credibility. The contrary testimony of other jurors, as well as
    the tenor of Juror No. 1’s own testimony, amply supports the
    conclusion that her assertions of misconduct by other jurors
    were the product of speculation, gross exaggeration, and
    perhaps conscious fabrication. We note, however, that the trial
    court did not specifically find any particular part of Juror No. 1’s
    testimony to be deliberately false. No finding of perjury was
    made, and Flinner does not demonstrate by argument from the
    record that any such finding was compelled.
    Although Juror No. 1 made unwarranted accusations of
    misconduct against others after the trial’s conclusion, we
    conclude the facts do not demonstrate she committed
    94
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    misconduct during the trial or deliberations. Flinner himself
    engages in speculation by assuming that because Juror No. 1
    gave exaggerated accounts of other jurors’ behavior, she must
    similarly have distorted the trial evidence. There was no
    evidence at the new trial hearing that Juror No. 1 said or did
    anything in deliberations to distort the evidence bearing on guilt
    or penalty. To the contrary, other jurors, including the
    foreperson and Juror No. 10, found her contributions, many
    based on detailed notes of the evidence, appropriate and helpful.
    Flinner’s assertion that Juror No. 1’s book idea led her
    make her unfounded and exaggerated claims of misconduct is
    also unsupported by the hearing evidence. Rather, as the trial
    court found, Juror No. 1’s claims appear to have been generated
    by her “palpable” antipathy to Jurors No. 10 and No. 12 and by
    her desire to be the center of attention.15 As far as the
    evidentiary hearing record discloses, Juror No. 1’s plan to write
    15
    The confrontation during deliberations that resulted from
    Juror No. 1’s dislike of Juror No. 10 was unfortunate and
    disturbing to the participants — Juror No. 10 testified Juror
    No. 1 called her a “bitch” and screamed at her, reducing her to
    tears — but it did not derail the deliberations. Juror No. 10 also
    testified that after the incident, which occurred “at the very,
    very end of all of our decisions,” the jury completed its
    deliberations and returned its verdicts; later, Juror No. 1
    apologized for her “inappropriate” conduct, though Juror No. 10
    did not feel the apology was sincere. Nor does the fact of an
    emotional confrontation between jurors necessarily indicate
    misconduct; it is not extraordinary for feelings among jurors to
    run high, especially in the context of disagreements during
    deliberations. (See People v. Keenan (1988) 
    46 Cal. 3d 478
    , 541–
    542 [that one juror may have made an angry threat against
    another does not show reversible jury misconduct].)
    95
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    a book about her jury experience did not cause her to misconduct
    herself in any other manner.
    Flinner cites no authority suggesting that by itself a juror’s
    plan to write a book about the case or the jury experience
    constitutes misconduct warranting reversal, and we have found
    none. It has been hypothesized that a juror’s profit motive could
    lead the juror into controversial behavior “for the sake of making
    a story worth telling,” or into “strong-arming the other members
    of the jury into an inequitable result that makes for good copy
    or a profitable film deal.” (Note, Capote in the Jury Box:
    Analyzing the Ethics of Jurors Writing Books (2006) 19 Geo. J.
    Legal Ethics 643, 645; see Sims v. Brown (9th Cir. 2005) 
    425 F.3d 560
    , 577 [juror who discussed writing a book during trial
    did not commit prejudicial misconduct where “there is no
    suggestion that she had a financial interest in any particular
    outcome”].) In response to such dangers, California law
    prohibits offering or accepting a payment to a juror in exchange
    for information about a criminal case during trial or for 90 days
    after discharge (if the payment is greater than $50). (Pen. Code,
    § 116.5.) The hearing evidence, however, did not show any
    agreement to write a book for profit: Juror No. 1 testified
    without contradiction that while she had received a positive
    response to her book proposal and was hoping to borrow money
    to complete the project, she never obtained an agreement for
    payment of any amount.
    Flinner compares Juror No. 1 to the hypothetical juror
    discussed in dictum in Dyer v. Calderon (9th Cir. 1998) 
    151 F.3d 970
    , 982, footnote 19, who “lies his way on [to the jury] because
    he secretly plans to write a memoir of the experience” and who,
    the court suggested, might then “vote differently to provide
    drama, or . . . inject personal prejudice into the jury room in an
    96
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    attempt to jazz up the deliberative process.” But while Juror
    No. 1 wrote on her questionnaire that she was “excited to be
    summoned” for jury service and that she thought Flinner’s case
    would be “very interesting,” there was no evidence she lied in
    order to be selected.16
    b. Asserted Misconduct by Juror No. 10
    Flinner contends Juror No. 10 “exhibited a clear bias by
    telling appellant she wanted him dead and by her personal
    infatuation with the lead detective.” He acknowledges that the
    trial court found untrue Juror No. 1’s allegations in this regard
    but maintains that finding was unsupported by the record.
    We disagree. The trial court’s finding was supported by
    substantial evidence and was based on the court’s assessment of
    the witnesses’ credibility. As such, it is entitled to deference.
    (People v. Nessler (1997) 
    16 Cal. 4th 561
    , 582.) Juror No. 10
    denied making hostile gestures or expressions to Flinner, and
    no other juror corroborated Juror No. 1’s account. Juror No. 10
    admitted making remarks about Detective Scully’s anatomy,
    16
    Flinner faults Juror No. 1 for failing to disclose on her
    questionnaire that she had been among the persons protected
    by a protective order her sister had obtained against an abusive
    former boyfriend. But no question on the questionnaire
    specifically called for such information. Juror No. 1 did disclose
    her sister’s history of drug addiction and related crime, which
    included an incident in which “[t]he group she hung with
    actually burned down her home.” At the new trial hearing, she
    acknowledged she also should have referenced that incident in
    answer to the question whether she or members of her family
    had ever been victims of crime. The trial court made no finding
    that Juror No. 1 was deceptive regarding the protective order or
    her sister’s former boyfriend, and we find nothing in the record
    that compels such a finding.
    97
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    but denied any acts that would suggest an “infatuation,” much
    less a “fixation.” As for Green Juror No. 10’s claim that he saw
    Juror No. 10 expose herself to Scully, cross-examination showed
    that to be mere speculation on his part.
    Juror No. 10 may not have conducted herself with perfect
    decorum throughout the trial. But the trial court found she did
    not commit the misconduct Juror No. 1 attributed to her, and
    we uphold that finding as supported by substantial evidence.
    C. Penalty Phase Issues
    1. Competence to Stand Trial
    Flinner contends the court erred, after the guilt verdicts
    were returned, in declining to suspend trial proceedings under
    Penal Code section 1368 in order to determine his competence
    to stand trial.
    Defendant Flinner’s jury returned its guilt-phase verdicts
    on October 16, 2003, but those verdicts were ordered sealed
    while codefendant Ontiveros’s jury continued deliberating. In
    the early morning of Sunday, October 19, jail personnel found
    Flinner, in his cell, in what the trial court, paraphrasing the jail
    records, described as “an apparent state of physical distress.”
    Flinner was hospitalized and was discharged on the morning of
    Tuesday, October 21. Declaring that he had been told Flinner
    had attempted suicide, defense counsel moved to initiate
    competency proceedings under Penal Code section 1368. In
    opposition, the prosecutor asserted Flinner’s apparent conduct
    on this occasion was consistent with his record of previous failed
    “ ‘attempts’ ” at suicide, other instances of malingering, and
    “manipulation and deceit,” and did not suggest an inability to
    proceed with the penalty phase. The court heard and denied the
    motion on Thursday, October 23.
    98
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    At the hearing, the court and counsel reviewed Flinner’s
    recent medical records. The court asked Attorney Mitchell
    whether, with the additional information in those records, he
    wished to give his view as to Flinner’s present competency to
    stand trial. Although Mitchell and cocounsel Resnick had met
    with Flinner the day before the hearing, Mitchell did not
    indicate Flinner acted or spoke in a manner suggesting
    incompetence. Mitchell believed himself “on the horns of a
    dilemma” as both Flinner’s attorney and an officer of the court;
    although he made no representations as to Flinner’s mental
    condition, he believed the examination and hearing
    requirements of Penal Code section 1368 had been triggered.
    The prosecutor observed that the medical records showed
    Flinner’s blood pressure and pulse at the time of his
    hospitalization, while elevated, were within the range that
    might be seen for a man of his age doing an intense physical
    activity and that when interviewed on October 21 by a sheriff’s
    department employee, Flinner denied any suicidal thoughts and
    stated, “ ‘I don’t really know what happened to me.’ ”
    Summing up the record, the trial court added that when
    interviewed, Flinner denied taking any drug, prescription or
    nonprescription, to excess, and that the court’s own observations
    at the October 23 hearing showed Flinner to be apparently alert,
    not in physical distress, and conversing with counsel in an
    apparently normal manner. The court found scant evidence
    Flinner’s condition on Sunday was the result of a suicide
    attempt, but even if it was, the evidence did not indicate
    incompetence to stand trial.
    “The constitutional guarantee of due process forbids a court
    from trying or convicting a criminal defendant who is mentally
    99
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    incompetent to stand trial. [Citations.] Section 1367 of the
    Penal Code, incorporating the applicable constitutional
    standard, specifies that a person is incompetent to stand trial
    ‘if, as a result of mental disorder or developmental disability, the
    defendant is unable to understand the nature of the criminal
    proceedings or to assist counsel in the conduct of a defense in a
    rational manner.’ (Id., subd. (a); see Dusky v. U.S. (1960) 
    362 U.S. 402
    [
    4 L. Ed. 2d 824
    , 
    80 S. Ct. 788
    ] [competence requires
    ‘ “sufficient present ability to consult with his lawyer with a
    reasonable degree of rational understanding” ’ and ‘ “a rational
    as well as factual understanding of the proceedings against
    him” ’].)” (People v. Rodas (2018) 
    6 Cal. 5th 219
    , 230–231.)
    “Penal Code section 1368 requires that criminal
    proceedings be suspended and competency proceedings be
    commenced if ‘a doubt arises in the mind of the judge’ regarding
    the defendant’s competence (id., subd. (a)) and defense counsel
    concurs (id., subd. (b)). This court has construed that provision,
    in conformity with the requirements of federal constitutional
    law, as meaning that an accused has the right ‘to a hearing on
    present sanity if he comes forward with substantial evidence
    that he is incapable, because of mental illness, of understanding
    the nature of the proceedings against him or of assisting in his
    defense.’ (People v. Pennington (1967) 
    66 Cal. 2d 508
    , 518 [
    58 Cal. Rptr. 374
    , 
    426 P.2d 942
    ], discussing Pate v. Robinson (1966)
    
    383 U.S. 375
    , 385–386 [
    15 L. Ed. 2d 815
    , 
    86 S. Ct. 836
    ].) ‘Once
    such substantial evidence appears, a doubt as to the sanity of
    the accused exists, no matter how persuasive other evidence —
    testimony of prosecution witnesses or the court’s own
    observations of the accused — may be to the contrary.’
    (Pennington, at p. 518.) As we have explained in more recent
    cases, substantial evidence for this purpose is evidence ‘that
    100
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    raises a reasonable or bona fide doubt’ as to competence, and the
    duty to conduct a competency hearing ‘may arise at any time
    prior to judgment.’ ” (People v. 
    Rodas, supra
    , 6 Cal.5th at
    p. 231.)
    We agree with the trial court that there was insufficient
    evidence of incompetence to call for suspension of criminal
    proceedings and a formal inquiry into competence to stand trial.
    The exact nature and cause of the medical crisis Flinner suffered
    on October 19 was unknown. After Flinner’s release from the
    hospital, he denied having suicidal thoughts or overdosing on
    any drug. Even assuming Flinner did try to kill himself in jail,
    it is not clear that was the result of any mental disorder; defense
    counsel pointed to nothing in the medical records so indicating.
    (See People v. Ramos (2004) 
    34 Cal. 4th 494
    , 509 [preference for
    receiving the death penalty and hoarding of medication for
    possible suicide attempt do not indicate incompetence].)
    Counsel said nothing to suggest Flinner was experiencing any
    difficulty understanding the proceedings or communicating with
    the defense team; nor did the court’s own observations give any
    indication Flinner was having problems following the
    proceedings or communicating with counsel. In the absence of
    substantial evidence of incompetence, the court properly denied
    Flinner’s Penal Code section 1368 motion.
    2. Cumulative Impact of Errors
    Flinner contends the errors and misconduct committed in
    his trial, considered cumulatively, deprived him of due process
    and a fair trial. We have found harmless the erroneous
    admission against Flinner of Ontiveros’s statements detailing
    Ontiveros’s killing of the victim (pt. II.B.7., ante) and the
    possibly erroneous admission of Flinner’s letter to
    101
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Representative Hunter (pt. II.B.3.h., ante). Examining their
    potential impact together, we find them cumulatively harmless
    as well. Though both evidentiary issues, they went to different
    factual aspects of the prosecution case; their potential prejudice
    would not have a strong tendency to accumulate.
    3. Constitutionality of California’s Death Penalty
    Law
    Flinner contends several aspects of California’s death
    penalty scheme violate the United States Constitution. We have
    considered and rejected these claims before, and we decline to
    revisit the following holdings.
    “[T]he California death penalty statute is not impermissibly
    broad, whether considered on its face or as interpreted by this
    court.” (People v. Dykes (2009) 
    46 Cal. 4th 731
    , 813.) Penal Code
    section 190.3, factor (a), which permits a jury to consider the
    circumstances of the offense in sentencing, does not result in
    arbitrary or capricious imposition of the death penalty in
    violation of the Fifth, Sixth, Eighth, or Fourteenth Amendments
    to the United States Constitution. (People v. Simon (2016) 
    1 Cal. 5th 98
    , 149; see Tuilaepa v. California (1994) 
    512 U.S. 967
    ,
    975–976, 978.)
    “The death penalty statute does not lack safeguards to avoid
    arbitrary and capricious sentencing, deprive defendant of the
    right to a jury trial, or constitute cruel and unusual punishment
    on the ground that it does not require either unanimity as to the
    truth of aggravating circumstances or findings beyond a
    reasonable doubt that an aggravating circumstance (other than
    Pen. Code, § 190.3, factor (b) or factor (c) evidence) has been
    proved, that the aggravating factors outweighed the mitigating
    factors, or that death is the appropriate sentence.” (People v.
    102
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Rangel (2016) 
    62 Cal. 4th 1192
    , 1235; accord, People v. McDowell
    (2012) 
    54 Cal. 4th 395
    , 444; People v. Demetrulias (2006) 
    39 Cal. 4th 1
    , 40–41.) We have held that the Supreme Court’s
    recent Sixth Amendment decisions (e.g., Hurst v. Florida (2016)
    577 U.S. ___ [
    136 S. Ct. 616
    ]; Cunningham v. California (2007)
    
    549 U.S. 270
    ; Blakely v. Washington (2004) 
    542 U.S. 296
    ; Ring
    v. Arizona (2002) 
    536 U.S. 584
    ; Apprendi v. New Jersey (2000)
    
    530 U.S. 466
    ) do not affect our conclusions in this regard.
    (Rangel, at p. 1235.)
    “Intercase proportionality review, comparing defendant’s
    case to other murder cases to assess relative culpability, is not
    required by the due process, equal protection, fair trial, or cruel
    and unusual punishment clauses of the federal Constitution.”
    (People v. Winbush (2017) 
    2 Cal. 5th 402
    , 490.) Flinner also
    refers in passing to the lack of “intra-case” proportionality
    review, but he does not argue his death sentence was grossly
    disproportionate to the offense committed or to the treatment of
    other participants in the capital crime. (See People v. Clark
    (2016) 
    63 Cal. 4th 522
    , 642.) Given the evidence that Flinner, a
    mature man acting on his own initiative, organized and
    participated in a callous and cold-blooded killing of his fiancée
    purely for his financial gain, we would not, were the claim made,
    conclude his sentence is grossly disproportionate to his
    individual culpability.
    Finally, “California’s use of the death penalty does not
    violate international law either by punishing certain first degree
    murders with death or by employing the procedures defendant
    complains of above.” (People v. Rhoades (2019) 
    8 Cal. 5th 393
    ,
    456.) “Defendant’s argument that the use of capital punishment
    ‘as regular punishment for substantial numbers of crimes’
    violates international norms of human decency and hence the
    103
    PEOPLE v. FLINNER
    Opinion of the Court by Kruger, J.
    Eighth Amendment to the United States Constitution fails, at
    the outset, because California does not employ capital
    punishment in such a manner. The death penalty is available
    only for the crime of first degree murder, and only when a special
    circumstance is found true; furthermore, administration of the
    penalty is governed by constitutional and statutory provisions
    different from those applying to ‘regular punishment’ for
    felonies.” (People v. 
    Demetrulias, supra
    , 39 Cal.4th at pp. 43–
    44.)
