    Los Angeles County Superior Court
    A392702
    __________________________________________________________
    February 13, 2020
    Justice Kruger authored the opinion of the Court, in which
    Chief Justice Cantil-Sakauye and Justices Chin, Corrigan, Liu,
    Cuéllar, and Groban concurred.

    In re GAY
    S130263
    Opinion of the Court by Kruger, J.
    Petitioner Kenneth Earl Gay was convicted of the first
    degree murder of a police officer and sentenced to death. In an
    earlier habeas corpus proceeding, we found that Gay’s trial
    counsel had defrauded Gay in order to induce Gay to retain him
    instead of the public defender, and then had gone on to commit
    serious errors during the trial’s penalty phase that undermined
    the reliability of the resulting death verdict. We accordingly
    granted habeas corpus relief and vacated the judgment of death.
    (In re Gay (1998) 
    19 Cal. 4th 771
    , 780 (Gay I).) Now, presented
    with additional allegations concerning trial counsel’s deficient
    performance during the guilt phase, we consider whether his
    performance undermined the reliability of the jury’s guilty
    verdict as well.
    To address this question, we ordered an evidentiary
    hearing before a referee. Examining Gay’s allegations in light
    of the extensive hearing record, the referee’s findings, and the
    trial record, we conclude Gay was denied his constitutional right
    to the assistance of competent counsel at the guilt phase of the
    trial, just as at the penalty phase. We grant habeas corpus relief
    and afford the People the opportunity to retry Gay if they so
    choose.
    In re GAY
    Opinion of the Court by Kruger, J.
    I.
    After a joint trial before separate juries in the Los Angeles
    County Superior Court, Gay and codefendant Raynard Paul
    Cummings were convicted of the first degree murder of Los
    Angeles Police Officer Paul Verna. (Pen. Code, § 189.) The
    juries found, as special circumstances, that defendants
    knowingly and intentionally killed a peace officer engaged in the
    performance of his duties (id., § 190.2, subd. (a)(7)) and
    committed the murder to prevent a lawful arrest (id., § 190.2,
    subd. (a)(5)). The juries also found that a principal was armed
    with a firearm (id., § 12022, subd. (a)) and that each defendant
    personally used a firearm (id., §§ 12022.5, subd. (a), 1203.06,
    subd. (a)(1)). Each jury returned a death verdict. (People v.
    Cummings (1993) 
    4 Cal. 4th 1233
    , 1255 (Cummings).)1 As
    explained further below, Gay’s death sentence was later vacated
    (Gay 
    I, supra
    , 19 Cal.4th at p. 780), and a second death
    judgment following penalty retrial was overturned on appeal
    (People v. Gay (2008) 
    42 Cal. 4th 1195
    , 1198 (Gay II)). Here, we
    are concerned solely with the validity of Gay’s underlying
    convictions.
    We previously have described the guilt phase evidence at
    length. (See 
    Cummings, supra
    , 4 Cal.4th at pp. 1257–1270.) We
    briefly summarize the relevant points here. Early in the
    1
    Gay also was charged with, and convicted of, 10 counts of
    robbery (Pen. Code, § 211); two counts of attempted robbery (id.,
    §§ 664, 211); conspiracy to commit robbery (id., §§ 182, 211); and
    being an ex-felon in possession of a concealable weapon (id.,
    § 12021). On appeal, the weapons possession conviction was
    upheld, but the remaining robbery-related convictions were all
    reversed. (
    Cummings, supra
    , 4 Cal.4th at pp. 1256, 1306–1315.)
    2
    In re GAY
    Opinion of the Court by Kruger, J.
    evening of June 2, 1983, Officer Verna, on motorcycle patrol,
    made a traffic stop in a residential neighborhood. The driver
    was Pamela Cummings.2           Gay was sitting in the front
    passenger’s seat, while Raynard Cummings was sitting in the
    backseat. Unbeknownst to Officer Verna, the car was stolen and
    Gay and Raynard Cummings recently had committed a series of
    robberies. Pamela stepped out of the car and told Officer Verna
    she had no driver’s license or registration for the car. When
    Officer Verna returned to the car to ask the occupants for
    identification, he was shot and fell. One of the occupants then
    got out of the car and shot the officer several more times. (Id. at
    pp. 1257–1258.) The initial shot would have been fatal on its
    own, as would most of the subsequent ones. (Id. at p. 1267.)
    The central issue at trial concerned the identity of the
    shooter or shooters. The prosecutor maintained that Raynard
    Cummings had fired the first shot while sitting in the backseat
    and then passed the gun to Gay, who stepped out of the car and
    fired the remaining shots at the fallen officer. Gay and
    Cummings each maintained that the other had fired all the
    shots. (
    Cummings, supra
    , 4 Cal.4th at p. 1259.) There were
    numerous eyewitnesses to the incident, but the witnesses’
    descriptions of this tragic event differed in significant respects.
    Pamela was the prosecution’s primary witness. She had
    been charged with special circumstances murder and robbery
    but pleaded guilty to two counts of robbery and to being an
    accessory to murder on the condition that she testify truthfully
    as a prosecution witness. (
    Cummings, supra
    , 4 Cal.4th at
    2
    To differentiate Pamela Cummings from her husband,
    Raynard Cummings, we will sometimes refer to Pamela by her
    first name.
    3
    In re GAY
    Opinion of the Court by Kruger, J.
    p. 1264, fn. 8.) Pamela testified she was driving a two-door 1979
    Oldsmobile Cutlass coupe when Officer Verna stopped her at
    about 5:40 p.m. (Id. at p. 1257.) She stepped out of the car and
    told Officer Verna she had no driver’s license or car registration.
    She gave him a check-cashing card for identification, which the
    officer used to complete a field interrogation card. Officer Verna
    returned to the car and bent down, putting his hands on his
    knees, leaned into the vehicle, and asked the occupants for
    identification. Pamela, who was standing near the curb, with
    the car between herself and the officer, heard a gunshot, saw
    Officer Verna grab his shoulder, and saw the barrel of a gun
    pointing straight across the front seat of the car between the
    head rests. She could not see who held the gun because her
    husband, sitting in the back, obstructed her view. According to
    Pamela, Gay then got out of the car, approached Officer Verna,
    and fired three shots into his back as he attempted to return to
    his motorcycle. The officer walked back a few feet and then fell
    to the ground. Gay stood over Officer Verna, shot him two more
    times, threw the gun on his body, and picked up the officer’s gun.
    Pamela and Gay reentered the car through the driver’s side
    door. Gay drove up the street, but then made a U-turn and
    returned, stopping by the fallen officer. Gay stepped out and
    retrieved Pamela’s identification card and the murder weapon.
    (Id. at pp. 1258, 1263.) The field interrogation card naming
    Pamela Cummings was left at the scene.
    Pamela also testified that on the night of the murder, Gay
    and Cummings reenacted the shooting in Gay’s home for the
    benefit of Gay’s wife, Robin. Gay extended his arm as if holding
    a gun and said, “ ‘Pow, pow, motherfucker. Take this,’ ” and said
    that he “ ‘got him good.’ ” Cummings used the same words in
    his reenactment. (
    Cummings, supra
    , 4 Cal.4th at p. 1264.)
    4
    In re GAY
    Opinion of the Court by Kruger, J.
    Eight additional eyewitnesses testified for the
    prosecution. Their versions of the events and identification of
    the shooter or shooters varied. The discrepancies turned in part
    on the differences in appearance between Gay and Cummings.
    Gay, who is a biracial man of African-American and Caucasian
    heritage, is much lighter in complexion than Cummings, who is
    a darker skinned African-American man. At six feet tall, Gay is
    six inches shorter than Cummings. On the evening of the
    murder, Gay was wearing a light gray long-sleeved shirt, while
    Cummings was wearing a maroon short-sleeved shirt.
    Twelve-year-old Oscar Martin was in the front yard of his
    home when he saw Officer Verna giving Pamela a ticket on the
    street in front of his house. Oscar went into his house and told
    his mother, who was in the kitchen, what he had seen. She told
    him to stay inside. He looked out the living room window and
    saw the back door of the car open and a person he later identified
    as Raynard Cummings get out and shoot the officer four times.
    After the shooting, the man got into the car and drove off. Oscar
    did not see anyone else in the car. (
    Cummings, supra
    , 4 Cal.4th
    at p. 1259.)
    Oscar’s mother, Rosa Maria Martin, did not see the
    murder. She had gone out and looked down her driveway after
    Oscar told her that a police officer was giving someone a ticket
    but saw nothing and went back inside. She then heard at least
    four gunshots, with a pause between the first one and the others.
    Oscar came to her and said: “ ‘They killed him.’ ” Rosa looked
    out the living room window and saw a two-door car driving
    slowly down the street. The driver, whom she identified as Gay,
    got out, picked up a revolver, and then got back into the car. A
    woman was in the passenger seat, but Rosa could not tell if
    5
    In re GAY
    Opinion of the Court by Kruger, J.
    anyone was in the rear seat. (
    Cummings, supra
    , 4 Cal.4th at
    p. 1260.)
    Robert Thompson was on a ladder in front of a house
    across the street and saw Officer Verna giving a ticket to a
    woman. Gay was in the front seat of the car and Raynard
    Cummings was in the rear seat on the passenger side.
    Thompson looked again when he heard a noise and saw the
    officer backing away from the driver’s side door holding his
    chest. Cummings was holding a gun in his right hand, which
    extended out of the car. After the first shot, Thompson jumped
    off the ladder and tried to hide behind a bush. When he looked
    again, he saw Gay get out of the front seat with a gun in his
    hand and walk toward the officer with his arm at full extension
    pointing the smoking gun at the officer on the ground. Gay
    stood straddling the officer, who was on his back. Cummings
    remained in the backseat of the car. (
    Cummings, supra
    , 4
    Cal.4th at pp. 1261–1262.)
    Gail Beasley’s preliminary hearing testimony was
    admitted at trial. She and another witness, Marsha Holt, had
    been in Beasley’s home across the street from the shooting.
    Beasley saw Officer Verna stop a car and speak to the driver,
    Pamela. Beasley looked again when she heard two gunshots
    and saw a Black man, six feet tall with very light skin and a
    Jheri curl, hold a gun with his arm extended at a 45-degree
    angle and shoot the officer four times. Another man was in the
    backseat. Pamela was still outside the car. (
    Cummings, supra
    ,
    4 Cal.4th at p. 1263.)
    Marsha Holt testified she saw a police officer giving a
    ticket to Pamela. Holt looked away but turned back when she
    heard a gunshot and then, after a pause, more shots. She saw
    6
    In re GAY
    Opinion of the Court by Kruger, J.
    the officer fall and saw the shooter pick up the officer’s gun, run
    back to the car, and drive away. At the preliminary hearing and
    at trial, Holt identified Gay as the shooter. (
    Cummings, supra
    ,
    4 Cal.4th at p. 1261.)
    Eleven-year-old Shannon Roberts was at a residence two
    or three houses away and saw Officer Verna giving a ticket to a
    woman who was standing outside a car. Shannon turned and
    went down the driveway but turned back when he heard a
    gunshot. He saw Gay shoot the officer four times. Gay then got
    into the passenger side of the car, the woman got into the
    driver’s side, and they left. A Black man was in the rear seat.
    Later, a different car stopped by the officer and the driver got
    out and picked up the gun. (
    Cummings, supra
    , 4 Cal.4th at
    p. 1262.)
    Rose Marie Perez was a passenger in a car that drove
    through the intersection at the end of the block where the
    shooting occurred. She looked up the street and saw Officer
    Verna falling backwards and a light-skinned Black man, whom
    she later identified as Gay, coming around the back of a car and
    walking toward the officer. She did not see anything in his
    hands. Perez also saw a person seated in the backseat of the car
    but did not see him leave the vehicle. That person had hair
    similar to that depicted in a photograph of Cummings.
    (
    Cummings, supra
    , 4 Cal.4th at p. 1263.)
    Shequita Chamberlain was a passenger in a different car
    that drove through the same intersection. She looked down the
    street and saw a tall, dark-skinned Black man and a police
    officer near a parked car and a police motorcycle. She heard a
    shot and saw the officer fall on his back. The Black man got into
    the car and drove off. Cummings was not the man she saw,
    7
    In re GAY
    Opinion of the Court by Kruger, J.
    although their complexions were similar. Gay’s complexion was
    lighter than that of the man she saw. (
    Cummings, supra
    , 4
    Cal.4th at p. 1261.)
    The prosecution also offered evidence of statements made
    by Gay and Cummings while they were in custody awaiting
    trial. Less than a month after Officer Verna was murdered,
    Gilbert Gutierrez, in jail on an unrelated murder charge, spoke
    to both defendants on different occasions about the events. Gay
    told him that Cummings first shot the officer from the backseat
    of the car, then got out of the car and shot Officer Verna twice
    more, after which Cummings emptied the gun. Cummings later
    told Gutierrez that he, Gay, and Pamela were on their way to
    get cocaine at the time they were stopped by Officer Verna.
    When Officer Verna asked him if he had any identification,
    Cummings said he did, pulled out a .38-caliber revolver, and
    shot the officer in the shoulder. Cummings told Gutierrez that
    he then got out of the car from the driver’s side, shot the officer
    twice in the back, and then emptied the gun, saying: “ ‘Here’s
    your identification, motherfucker.’ ” (
    Cummings, supra
    , 4
    Cal.4th at p. 1264.) Gutierrez testified that Cummings was
    proud of shooting Officer Verna and bragged about it.
    Cummings told Gutierrez that he had thrown his gun down and
    picked up the officer’s gun, and that Gay had recovered the gun
    used by Cummings when they went back. (Id. at pp. 1264–
    1265.)
    Deputy Sheriff Rick McCurtin testified that in April 1984,
    he was on guard duty while Cummings and other inmates were
    in the jail shower. As another deputy walked by, “inmate Brooks
    said, ‘There is Paul Verna,’ after which Brooks and Cummings
    extended their right arms as if shooting a pistol and said ‘Pow,
    Pow.’ Cummings then said to [Deputy] McCurtin: ‘Let me show
    8
    In re GAY
    Opinion of the Court by Kruger, J.
    you how it was done. This is how it was done. First two in the
    back. Pow, pow. Walked up and four more. Pow, pow, pow,
    pow.’ Cummings’s arm was then pointing down at the ground.
    On cross-examination[,] the witness quoted defendant
    Cummings as having said: ‘Then we put four more.’ (Italics
    added.)” (
    Cummings, supra
    , 4 Cal.4th at pp. 1265–1266.)
    Deputy Sheriff David LaCasella testified that in April
    1985, he escorted defendants from the courtroom to the main
    lockup. The coroner had just testified about the postmortem
    examination of Officer Verna, explaining that he had numbered
    the bullet wounds in the order he examined them from one
    through six. The coroner stated that the first shot fired was
    “ ‘Number 6.’ ” (
    Cummings, supra
    , 4 Cal.4th at p. 1258.) Deputy
    LaCasella placed Cummings and Gay in adjacent cells. “He
    later heard Cummings yell: ‘You know how he got number six[,]
    don’t you?’ Gay then replied: ‘Number six?’ Cummings said
    ‘yeh,’ and then yelled:       ‘That’s the one I put in the
    motherfucker.’ ” (Id. at p. 1266.)
    Deputy Sheriff Michael McMullan testified that about a
    year after the murder, he and Sergeant George Arthur were
    escorting Cummings in the central jail when other inmates
    began chanting “ ‘dead man walking’ ” as Cummings passed by.
    (
    Cummings, supra
    , 4 Cal.4th at p. 1265.) Cummings responded
    by saying: “ ‘I am no ghost. The only ghost I know is Verna. I
    put six in him.’ ” (Ibid.) As he was put in his cell, Cummings
    said to Sergeant Arthur: “ ‘He took six of mine . . . . If I see you
    all on the streets I hope you are quicker than Verna.’ ” (Ibid.)
    In defense, Gay argued that Cummings alone had shot
    Officer Verna. In support of this defense, Gay recalled some of
    the prosecution’s eyewitnesses as defense witnesses. Rosa
    9
    In re GAY
    Opinion of the Court by Kruger, J.
    Maria Martin again testified that, after the shooting, she saw a
    car being driven toward the fallen officer. Gay left the car,
    picked up a gun, reentered the car, and drove it away. She did
    not see Gay shoot anybody. Rose Marie Perez testified that as
    she passed through a nearby intersection, she saw Gay walk
    around the rear of the stopped automobile. At that time, the
    officer was already falling down. Perez did not see anything in
    Gay’s hand. (
    Cummings, supra
    , 4 Cal.4th at p. 1269.)
    Gay also recalled Pamela Cummings as a witness. She
    testified that she was sure a shot had been fired from within the
    car. Gay’s counsel attempted to impeach her by eliciting an
    admission that she had lied in prior statements about the
    murder, by asking her about testimony by other eyewitnesses
    that was inconsistent with hers, and by posing questions
    designed to undermine the credibility of her description of the
    events and to suggest that she was not truthful in stating that
    she did not know who fired the first shot. Counsel for Cummings
    then elicited further testimony on cross-examination that
    Pamela saw Gay slide across the front seat of the car, come out
    firing a gun, and repeatedly shoot the victim. (
    Cummings, supra
    , 4 Cal.4th at pp. 1269–1270.)
    II.
    This court affirmed the murder convictions and judgments
    of death on automatic appeal. (
    Cummings, supra
    , 4 Cal.4th at
    p. 1343.) While that appeal was still pending, Gay filed his first
    petition for a writ of habeas corpus. Among other claims, Gay
    argued that the judgment should be vacated because he had
    received constitutionally ineffective representation from his
    trial counsel, Daye Shinn. We issued an order to show cause
    10
    In re GAY
    Opinion of the Court by Kruger, J.
    why relief should not be granted, limited to a claim of ineffective
    assistance at the penalty phase.
    Following a reference hearing, we granted the petition for
    a writ of habeas corpus and ordered a new penalty phase trial.
    (Gay 
    I, supra
    , 19 Cal.4th at p. 780.) In granting relief, we held
    that Shinn had rendered deficient performance by inducing Gay
    to admit to having committed several robberies—admissions
    that were used against him at the penalty phase—while
    presenting “little mitigating evidence” even though “much more
    potentially mitigating evidence was easily accessible.” (Id. at
    p. 794.)
    These deficiencies, we explained, could be traced in part to
    serious misconduct in the very foundation of the attorney-client
    relationship. The referee concluded that Shinn—who would
    later be disbarred for misappropriation of client funds in an
    unrelated matter (Gay 
    I, supra
    , 19 Cal.4th at p. 780, fn. 5)—had
    used fraudulent means to induce Gay to retain him as his
    attorney. Visiting Gay in county jail, Shinn and an associate,
    Marcus McBroom, urged Gay to hire Shinn, promising that a
    group of unidentified (and, in truth, nonexistent) Black
    businessmen would pay his legal fees. Shinn later directed Gay
    to tell the court—falsely—that his parents had paid a retainer
    to Shinn and would pay his legal fees. (Id. at pp. 781, 794.)
    Shinn engaged in these machinations in order to engineer his
    eventual appointment by the court. (Id. at p. 794.)
    McBroom was an assistant to Dr. Fred Weaver, a
    psychiatrist whom Shinn hired to examine Gay’s mental health.
    (Gay 
    I, supra
    , 19 Cal.4th at pp. 783, 795–797.) We concluded
    that “Shinn did not select Dr. Weaver because of his
    demonstrated competence,” but because “Shinn, McBroom, and
    11
    In re GAY
    Opinion of the Court by Kruger, J.
    Weaver had a capping relationship pursuant to which Weaver
    was retained in cases in which McBroom had arranged
    representation by Shinn.” (Id. at p. 796.) Dr. Weaver accepted
    the assignment “only with the understanding that the case
    would not be complicated and would not place demands on his
    time.” (Id. at p. 828.) Shinn did not undertake, nor did he direct
    Dr. Weaver to undertake, “the type of penalty phase
    investigation and preparation expected of competent
    professionals in a capital case,” including a thorough
    assessment of Gay’s mental health. (Id. at p. 796.)
    Finally, we noted that “at the time Shinn represented
    petitioner, Shinn labored under [an] undisclosed potential
    conflict of interest—he was being investigated for
    misappropriation of client funds by the office of the same district
    attorney who was his adversary in the prosecution of petitioner.”
    (Gay 
    I, supra
    , 19 Cal.4th at p. 828.) While the record did not
    reveal whether Shinn was influenced by this “distraction,” we
    noted that the potential conflict “contribute[d] to our lack of
    confidence in the verdict when considered with Shinn’s other
    failings.” (Ibid.)
    We summarized our conclusions as follows: “We are
    unable to put confidence in a verdict of death rendered by a jury
    that reaches a death penalty verdict for a defendant represented
    by an attorney who has defrauded the court in seeking
    appointment, and whose unethical conduct led directly to the
    retention of a mental health expert who the attorney agreed
    would not be called upon to do a thorough assessment of the
    defendant and who testified that the defendant had a
    sociopathic personality. Confidence in the verdict is further
    undermined by counsel’s incompetent conduct contributing to
    the penalty phase jury’s consideration of evidence that the
    12
    In re GAY
    Opinion of the Court by Kruger, J.
    defendant is a serial robber with a sociopathic personality, and
    by recognition that the jury did not have the opportunity to
    consider a substantial amount of mitigating evidence that
    competent counsel would have presented. We conclude there is
    a reasonable probability that absent counsel’s numerous failings
    and the conflicts of interest with which he was burdened, a
    different penalty verdict would have been reached. We do not,
    therefore, have confidence in the penalty verdict reached in this
    case.” (Gay 
    I, supra
    , 19 Cal.4th at pp. 829–830, fn. omitted.)
    Following a penalty phase retrial, Gay was again
    sentenced to death in 2000. (Gay I
    I, supra
    , 42 Cal.4th at
    p. 1198.) On appeal, we again reversed the death judgment, this
    time because the trial court had erred in preventing the defense
    from presenting, and the jury from considering, evidence that
    Gay was not the shooter. The improperly excluded evidence
    included testimony from four children who were eyewitnesses to
    the shooting—the prosecution had objected on the grounds the
    children had not been called to testify at the guilt phase of the
    trial—as well as various statements Cummings made in which
    he claimed to be the sole shooter. (Id. at pp. 1214–1216, 1227.)
    The court’s errors, we ruled, prejudiced Gay by hampering his
    ability to argue to the jury that it should consider lingering
    doubt as to guilt as a mitigating circumstance. (Id. at pp. 1226–
    1227.)
    On December 28, 2004, while the automatic appeal from
    the second judgment of death was still pending, Gay filed this
    petition for a writ of habeas corpus challenging his convictions
    13
    In re GAY
    Opinion of the Court by Kruger, J.
    and related findings.3 Gay raised 26 claims for relief, including
    claims that he is actually innocent of capital murder and that he
    received ineffective assistance of counsel at the guilt phase of
    his original trial. We issued an order to show cause why Gay
    was not entitled to habeas corpus relief from his underlying
    murder conviction because defense counsel Shinn had failed to
    adequately investigate and present evidence at the guilt phase
    of the trial, among other failings, and also had had a conflict of
    interest that prejudicially affected his representation at the
    guilt phase. At the request of both parties, we issued a stay of a
    further penalty phase retrial pending our resolution of these
    issues.
    Following the filing of a return and traverse, we ordered
    the Los Angeles County Superior Court to select a judge to act
    as a referee and conduct a hearing to take evidence and make
    findings of fact on the following questions:
    “1. What actions did petitioner’s trial counsel, Daye
    Shinn, take to investigate a defense at the guilt phase of
    petitioner’s capital trial that petitioner did not participate in the
    murder of Officer Verna? What were the results of that
    investigation?
    3
    The procedural bar against successive habeas corpus
    petitions does not apply here because Gay’s first petition was
    filed before our decision in In re Clark (1993) 
    5 Cal. 4th 750
    , 769–
    774, in which we clarified that the successiveness bar is
    nondiscretionary. Before Clark, Gay would not have been on
    notice that failure to raise issues in his first petition would
    necessarily preclude their later consideration. (See In re
    Robbins (1998) 
    18 Cal. 4th 770
    , 788, fn. 9 [“Clark serves to notify
    habeas corpus litigants that we shall apply the successiveness
    rule when we are faced with a petitioner whose prior petition
    was filed after the date of finality of Clark”].)

    Opinion of the Court by Kruger, J.
    “2. What additional evidence supporting that defense, if
    any, could petitioner have presented at the guilt phase of his
    capital trial? What investigative steps, if any, would have led to
    this additional evidence?
    “3. How credible was this additional evidence? What
    circumstances, if any, weighed against the investigation or
    presentation of this additional evidence? What evidence
    rebutting this additional evidence reasonably would have been
    available to the prosecution at trial?
    “4. Did the Los Angeles County District Attorney’s
    investigation of allegations that petitioner’s trial counsel, Daye
    Shinn, had engaged in acts of embezzlement unrelated to
    petitioner’s case give rise to a conflict of interest in petitioner’s
    case? If so, describe the conflict of interest.
    “5. If this conflict of interest existed, did it affect trial
    counsel Daye Shinn’s representation of petitioner? If so, how?”
    Superior Court Judge Lance Ito was appointed as referee
    and held an evidentiary hearing. Shinn, who had died in 2006,
    did not testify at the hearing. After the hearing, Judge Ito filed
    a 75-page report containing findings of fact. Gay filed extensive
    exceptions to the report. The Attorney General did not take
    issue with any findings relevant to our disposition of the case.
    III.
    A.
    Because a petition for a writ of habeas corpus is a
    collateral attack on a presumptively final criminal judgment,
    Gay bears the burden of proving his entitlement to relief by a
    preponderance of the evidence. (In re Cowan (2018) 5 Cal.5th
    235, 243; In re Price (2011) 
    51 Cal. 4th 547
    , 559.) The referee’s
    15
    In re GAY
    Opinion of the Court by Kruger, J.
    factual findings are “entitled to great weight where supported
    by substantial evidence.” (In re Hamilton (1999) 
    20 Cal. 4th 273
    ,
    296; accord, In re Welch (2015) 
    61 Cal. 4th 489
    , 501.) Those
    findings are not, however, conclusive, and “we can depart from
    them upon independent examination of the record even when
    the evidence is conflicting.” (Hamilton, at p. 296; accord,
    Cowan, at p. 243.) The ultimate responsibility for determining
    whether Gay is entitled to relief rests with this court. (In re
    Thomas (2006) 
    37 Cal. 4th 1249
    , 1256–1257.)
    Gay argues that Shinn rendered ineffective assistance at
    the guilt phase, in violation of his rights to the assistance of
    counsel under the Sixth Amendment to the United States
    Constitution and article I, section 15, of the California
    Constitution.    “An ineffective assistance claim has two
    components: A petitioner must show that counsel’s performance
    was deficient, and that the deficiency prejudiced the defense.”
    (Wiggins v. Smith (2003) 
    539 U.S. 510
    , 521; accord, Strickland
    v. Washington (1984) 
    466 U.S. 668
    , 687 (Strickland).) Whether
    counsel’s performance was deficient, and whether any deficiency
    prejudiced defendant, are mixed questions of law and fact
    subject to our independent review. (In re 
    Thomas, supra
    , 37
    Cal.4th at p. 1256.)
    We evaluate Shinn’s guilt phase performance according to
    well-established standards. “Representation of a criminal
    defendant entails certain basic duties. Counsel’s function is to
    assist the defendant, and hence counsel owes the client a duty
    of loyalty . . . . Counsel also has a duty to bring to bear such skill
    and knowledge as will render the trial a reliable adversarial
    testing process.” 
    (Strickland, supra
    , 466 U.S. at p. 688.) “These
    basic duties neither exhaustively define the obligations of
    counsel nor form a checklist for judicial evaluation of attorney
    16
    In re GAY
    Opinion of the Court by Kruger, J.
    performance.”      (Ibid.)  Rather, “[t]o establish deficient
    performance, a petitioner must demonstrate that counsel’s
    representation ‘fell below an objective standard of
    reasonableness,’ ” as measured by “ ‘prevailing professional
    norms.’ ” (Wiggins v. 
    Smith, supra
    , 539 U.S. at p. 521, quoting
    Strickland, at p. 688.) When applying this standard, we ask
    whether any reasonably competent counsel would have done as
    counsel did. (In re Reno (2012) 
    55 Cal. 4th 428
    , 465.) Counsel’s
    performance “is assessed according to the prevailing norms at
    the time.” (In re 
    Thomas, supra
    , 37 Cal.4th at p. 1257.) Judicial
    review of counsel’s performance is deferential; to establish
    deficient performance, the defendant “must overcome the
    presumption that, under the circumstances, the challenged
    action ‘might be considered sound trial strategy.’ ” (Strickland,
    at p. 689.)
    As Gay notes, we have already found that Shinn failed in
    his most basic duty, loyalty to his client, having defrauded Gay
    in order to induce him to discharge the public defender and
    retain Shinn instead. (Gay 
    I, supra
    , 19 Cal.4th at pp. 794–795,
    828–829.) But according to Gay, that is not all; Shinn’s lack of
    professionalism pervaded the entire course of his pretrial
    investigation and advocacy.           Among other purported
    shortcomings in Shinn’s representation, Gay points to Shinn’s
    decision to have Gay confess to involvement in the string of
    robberies, which we have already found to constitute deficient
    performance in Gay I. (Gay 
    I, supra
    , 19 Cal.4th at pp. 791–794.)
    Gay also argues that Shinn failed to conduct any meaningful
    investigation to identify, and thus failed to present, numerous
    witnesses who could have greatly strengthened Gay’s argument
    that Cummings was solely responsible for the murder of Officer
    Verna. We conclude Shinn was deficient in every regard.
    17
    In re GAY
    Opinion of the Court by Kruger, J.
    B.
    Before trial, Shinn formed a plan to have Gay take a
    polygraph test from the prosecution’s expert polygraph
    examiner. Shinn’s apparent hope was that if Gay passed, he
    would be permitted to testify as a prosecution witness
    implicating Cummings and would be offered a favorable plea
    bargain. The prosecution offered no deal but instead required
    as a condition of any examination that Gay first meet with the
    prosecutor, a prosecution investigator, Jack Holder, and a
    detective investigating the Verna murder, John Helvin.
    (
    Cummings, supra
    , 4 Cal.4th at pp. 1315–1316.)
    In advance of the meeting, Shinn advised Gay to admit
    participation in the string of robberies preceding the Verna
    murder. Gay followed this advice. At the beginning of the
    interview, Gay was told that anything he said could and would
    be used against him. Gay and Shinn each expressly confirmed
    that no deal was in place and nothing had been promised in
    exchange for Gay’s participation in the interview. Then, as
    recommended by Shinn, Gay admitted collaborating with
    Cummings in a series of five armed robberies. (
    Cummings, supra
    , 4 Cal.4th at pp. 1316–1317.) Gay’s taped confessions
    were played for the jury as part of the prosecution’s case. (Id. at
    p. 1315; Gay 
    I, supra
    , 19 Cal.4th at p. 781.)
    On direct appeal, Gay challenged Shinn’s conduct in
    advising him to confess, and later eliciting testimony that the
    confessions were truthful, as deficient. We found the claim moot
    as to the robbery charges and did not expressly address it in
    connection with the murder charge. (
    Cummings, supra
    , 4
    Cal.4th at p. 1341.) In resolving Gay’s first habeas corpus
    petition, however, we reached the merits and concluded Shinn
    18
    In re GAY
    Opinion of the Court by Kruger, J.
    performed incompetently. (Gay 
    I, supra
    , 19 Cal.4th at pp. 791–
    794.)
    That conclusion remains sound. Shinn had Gay waive his
    right against self-incrimination and confess to a series of armed
    robberies. He told Gay that if the prosecution did not agree to
    have Gay testify on the state’s behalf, these statements would
    not be used, despite the fact no agreement to that effect had been
    reached. At a hearing outside the jury’s presence, Gay testified
    that he disregarded the warning that his statements could be
    used against him because he believed his attorney’s contrary
    assurances. The confessions allowed Gay’s own words to be used
    by the prosecution to establish that Gay and Cummings were
    crime partners, and that each had an equal motive to avoid
    capture and arrest by a police officer, and thus equal motive to
    shoot Officer Verna. “Shinn not only acted as a second
    prosecutor by creating the evidence that led to petitioner’s
    conviction of the robberies, his conduct permitted the prosecutor
    to portray petitioner as an admitted serial robber who killed a
    police officer to avoid arrest and prosecution for the robberies.”
    (Gay 
    I, supra
    , 19 Cal.4th at p. 793.)
    Though Shinn may have hoped the prosecution would
    eventually offer a deal, Gay’s “statement was not made in the
    course of plea negotiations, but as a precondition to initiation of
    any discussion of disposition of the charges.” (
    Cummings, supra
    ,
    4 Cal.4th at p. 1318.) Shinn persuaded Gay to confess by
    assuring him his statements would not be used unless a deal
    was struck but had no such agreement with the prosecution.
    During a hearing on the admissibility of his confession, Gay
    learned for the first time there was no agreement that would
    protect him. Under examination by his own counsel, Gay
    testified: “I don’t feel I was tricked by [the prosecutor]. . . . [¶]
    19
    In re GAY
    Opinion of the Court by Kruger, J.
    I was tricked by you, I feel.” No competent and loyal counsel
    would have deceived his own client, as Shinn did. Nor would
    competent counsel have allowed a client to be interviewed in the
    fashion Shinn permitted, following an express advisement that
    any statements could be used in court, without any agreement
    in place to protect the client. (Gay 
    I, supra
    , 19 Cal.4th at
    pp. 791–793; see 1 Amsterdam, Trial Manual for the Defense of
    Criminal Cases (4th ed. 1984) § 213(C), p. 1-245 [describing
    understanding that counsel should exercise caution before
    allowing client “to divulge[] any incriminating information to
    anyone”].)
    Consistent with Gay I, we conclude Shinn’s decision to
    have Gay confess to the series of robberies fell well below
    prevailing professional norms.
    C.
    We next turn to the central focus of Gay’s present claim.
    To make out Gay’s defense at trial, Shinn relied largely on the
    prosecution’s witnesses, who collectively provided only limited
    help to the theory of the defense. Gay argues Shinn took this
    tack not for lack of better options, but simply because he failed
    to conduct an adequate investigation into potential witnesses
    who might have provided much more helpful testimony. As a
    consequence, Shinn failed to introduce significant testimony
    that would have raised doubts about Gay’s guilt. Although Gay
    identifies numerous witnesses he claims a competent attorney
    would have called, including various types of expert and lay
    witnesses, we focus our attention on two particular categories:
    (1) eyewitnesses to the shooting who could have described the
    shooter in terms that tended to support Gay’s theory that
    Cummings, not Gay, fired all the fatal shots; and (2) peace
    20
    In re GAY
    Opinion of the Court by Kruger, J.
    officers who could have testified to Cummings’s admissions of
    guilt. For purposes of our inquiry, these two categories of
    witnesses are enough.4
    Whether Shinn’s failure to call particular witnesses was
    deficient, and whether his investigation before trial was
    deficient, are legally intertwined, and so we must consider them
    together. “ ‘[B]efore counsel undertakes to act, or not to act,
    counsel must make a rational and informed decision on strategy
    and tactics founded upon adequate investigation and
    preparation.’ ” (In re 
    Thomas, supra
    , 37 Cal.4th at p. 1258,
    quoting In re Marquez (1992) 
    1 Cal. 4th 584
    , 602.) “[S]trategic
    choices made after thorough investigation of law and facts
    relevant to plausible options are virtually unchallengeable; and
    strategic choices made after less than complete investigation are
    reasonable precisely to the extent that reasonable professional
    judgments support the limitations on investigation. In other
    words, counsel has a duty to make reasonable investigations or
    to make a reasonable decision that makes particular
    investigations unnecessary. In any ineffectiveness case, a
    particular decision not to investigate must be directly assessed
    for reasonableness in all the circumstances, applying a heavy
    4
    We considered the same two categories of witnesses in our
    decision invalidating the outcome of the penalty retrial, at which
    these witnesses’ testimony had been improperly excluded. (Gay
    I
    I, supra
    , 42 Cal.4th at pp. 1214–1218, 1223–1224.) We
    explained there that “[e]vidence indicating that defendant was
    not the actual shooter would have been important to the jury in
    assessing the appropriate penalty”; the testimony of those who
    identified Cummings as the sole shooter, and those who heard
    Cummings admit to being the sole shooter, might well have
    altered the jury’s decision. (Id. at p. 1227.)
    21

    Opinion of the Court by Kruger, J.
    measure of deference to counsel’s judgments.” 
    (Strickland, supra
    , 466 U.S. at pp. 690–691; accord, In re Thomas, at
    p. 1258.)
    1.
    During the shooting, Ejinio Rodriguez was at the same
    location as Shannon Roberts, who testified for the prosecution.
    In a 2003 statement to a defense investigator, Ejinio5 said he
    had been playing in his front yard when he noticed a police
    officer making a traffic stop of a car containing a woman and two
    men. Ejinio later heard what he initially thought were
    firecrackers. He saw one of the men, whom he believed was the
    shooter, standing over the officer while the other man remained
    in the car. The men and woman drove off but made a U-turn
    and returned to the fallen officer. The other man then got out
    of the car and retrieved the officer’s gun. Ejinio described the
    shooter as “a black man who had dark skin and was wearing a
    dark shirt.” Ejinio described the nonshooter who picked up the
    gun as having “much lighter skin.” The referee found that this
    description “points more strongly towards Raynard Cummings
    than petitioner” as the shooter based on their respective
    complexions and clothing.
    Ejinio’s 14-year-old sister, Irma, was also in the front yard
    of their house when the officer was shot. The next day, she
    described the shooter to a police officer “as a dark skinned male
    negro, about twenty-five years old with a three[-] to four[-]inch
    afro.” According to Irma, the shooter was the driver of the car
    and was “black and very tall. The passenger seated next to the
    5
    We sometimes refer to Ejinio and his sister Irma
    Rodriguez (discussed below) by their first names to avoid
    confusion.
    22
    In re GAY
    Opinion of the Court by Kruger, J.
    driver was a lighter skinned person . . . .” Like Ejinio, Irma
    described the car driving off, then returning and the light-
    skinned passenger getting out to retrieve a gun. The referee
    found that Irma’s description of the shooter “point[s] more
    strongly towards Raynard Cummings . . . , with the added fact
    that she differentiates between the shooter and a lighter
    complexion male Negro wearing the white long sleeved shirt as
    the front seat passenger.”
    The referee found that Shinn read the police investigation
    file. Irma’s name, address, and witness statement were
    provided in that file. Ejinio was mentioned in the file as having
    been present during the shooting and was also identified in the
    grand jury testimony of Shannon Roberts, with whom he had
    been playing. Despite this, the referee found Ejinio was never
    interviewed before the 1985 trial.        It likewise appears
    undisputed that the defense never interviewed Irma. Evidence
    at the reference hearing helps to explain why. The referee’s
    findings and the testimony of Shinn’s investigator, Douglas
    Payne, establish that Payne spent parts of three days in
    January 1985 seeking out eyewitnesses. Payne confirmed that
    this investigation resulted from directions he received around
    Christmas 1984 to canvas the area near the murder scene for
    witnesses. By the time Payne conducted his investigation, 19
    months had elapsed since the murder, jury selection was well
    underway, and opening statements were only a month away.
    As with other aspects of performance, we measure the
    sufficiency of an attorney’s investigation according to the
    prevailing norms at the time. (See Rompilla v. Beard (2005) 
    545 U.S. 374
    , 387; In re 
    Thomas, supra
    , 37 Cal.4th at p. 1262.) In
    the early 1980s, the “American Bar Association Standards for
    Criminal Justice published at the time described the duty to
    23
    In re GAY
    Opinion of the Court by Kruger, J.
    investigate this way: ‘It is the duty of the lawyer to conduct a
    prompt investigation of the circumstances of the case and to
    explore all avenues leading to facts relevant to the merits of the
    case and the penalty in the event of conviction.’ ” (In re Thomas,
    at p. 1262, quoting 1 ABA Stds. for Crim. Justice (2d ed. 1982
    supp.) std. 4-4.1.)6 Consistent with the ABA standards, a
    contemporaneous treatise stresses the importance of a timely
    investigation: “[D]efense investigation should begin promptly.
    Speed may not be essential in a particular case, but counsel
    cannot know this until s/he learns something about the case.
    Generally, speed is essential. Physical facts change. An object
    of importance may be discarded. Witnesses may disappear or
    forget.” (1 Amsterdam, Trial Manual for the Defense of
    Criminal Cases, supra, § 108, p. 1-116; see Kayer v. Ryan (9th
    Cir. 2019) 
    923 F.3d 692
    , 714–715 [holding that defense counsel’s
    delay in conducting a capital case investigation may constitute
    ineffective assistance].)
    Shinn’s investigator agreed that Shinn was “going
    through the motions.” Shinn’s apparent decision to wait until
    the last minute before having his investigator seek out
    exculpatory eyewitness accounts cannot be reconciled with
    prevailing norms. Shinn’s trial strategy included relying on
    percipient eyewitnesses who said Cummings was the shooter.
    (See In re Lucas (2004) 
    33 Cal. 4th 682
    , 725 [the reasonableness
    of any limits on investigation should be evaluated in light of
    counsel’s strategy].) Shinn was retained in August 1983; his
    6
    Both the United States Supreme Court and this court have
    treated those standards as persuasive evidence of prevailing
    professional norms. (See Rompilla v. 
    Beard, supra
    , 545 U.S. at
    p. 387; Wiggins v. 
    Smith, supra
    , 539 U.S. at p. 524; In re
    
    Thomas, supra
    , 37 Cal.4th at p. 1262.)
    24
    In re GAY
    Opinion of the Court by Kruger, J.
    investigator began working for him no later than May 1984.
    Long before January 1985, one month before opening
    statements, Shinn could and should have had his investigator
    seek out eyewitnesses to determine whether they would testify
    favorably and to preserve their recollections. We conclude
    Shinn was deficient for not investigating in a timely fashion the
    availability of favorable eyewitness testimony.
    The referee’s findings identify two reasons competent
    counsel might have ultimately hesitated to call Ejinio as a
    witness after interviewing him and learning that his account of
    the shooting was consistent with Gay’s defense. First, Ejinio
    was young—“about to turn nine” at the time of the shooting.7
    Second, Ejinio was emotionally affected by the shooting. The
    referee found that when Ejinio testified at the reference hearing
    more than 30 years later, he was “anxious and distressed”; even
    after so much time, “the events of June 1983 were still very
    upsetting to him.” The referee noted that the child’s parents had
    been reluctant to permit his older sister, Irma, to be involved in
    the police investigation and found it likely “they would have
    [had] a similar reluctance on behalf of the younger Ejinio.”
    The referee’s findings, which we accept, show there are
    reasons why competent counsel might reasonably have decided
    not to call Ejinio as a witness after interviewing him. But Shinn
    never met with Ejinio, directly or through an investigator, and
    7
    The referee further found that had Ejinio testified, the
    trial court would likely have instructed the jury with CALJIC
    No. 2.20.1, an instruction governing the evaluation of testimony
    by witnesses 10 years old or younger. Gay takes exception to
    this finding because the instruction was not promulgated until
    1986, after Gay’s trial in 1985. The Attorney General does not
    dispute this point, and we do not adopt this finding.
    25
    In re GAY
    Opinion of the Court by Kruger, J.
    so neither learned what Ejinio might say nor placed himself in
    a position to make an informed tactical decision concerning
    whether potential drawbacks to calling Ejinio might outweigh
    the benefits. “[S]trategic choices made after less than complete
    investigation are reasonable precisely to the extent that
    reasonable professional judgments support the limitations on
    investigation.” 
    (Strickland, supra
    , 466 U.S. at pp. 690–691.)
    Shinn’s failure to call Ejinio as a witness cannot be accepted as
    a legitimate tactical choice because, under prevailing norms, his
    failure promptly to seek out and interview witnesses such as
    Ejinio was not the product of a reasonable professional
    judgment. (See Wiggins v. 
    Smith, supra
    , 539 U.S. at pp. 522–
    523.)
    When “counsel were not in a position to make a reasonable
    strategic choice as to whether to” present evidence “because the
    investigation supporting their choice was unreasonable”
    (Wiggins v. 
    Smith, supra
    , 539 U.S. at p. 536), a court must
    consider whether there is “a reasonable probability that a
    competent attorney . . . would have introduced” the evidence the
    attorney’s inadequate investigation failed to unearth (
    id. at p.
    535). Here, eyewitness testimony was critical to the jury’s
    decision about the identity of the shooter or shooters. And young
    witnesses were already a feature of this trial: The prosecution
    relied in part on the eyewitness testimony of 12-year-old Oscar
    Martin and 11-year-old Shannon Roberts. (
    Cummings, supra
    , 4
    Cal.4th at pp. 1259, 1262.)8 In these circumstances, there is a
    8
    Our previous opinion indicated Roberts was 13.
    (
    Cummings, supra
    , 4 Cal.4th at p. 1262.) Reexamination of the
    record confirms that while Roberts was 13 at the time of trial,
    he was 11 at the time of the shooting, the relevant benchmark
    for comparative purposes.
    26
    In re GAY
    Opinion of the Court by Kruger, J.
    reasonable probability that competent counsel, having
    conducted an adequate investigation, would have presented
    Ejinio’s testimony to bolster Gay’s case that Cummings was the
    lone shooter. The uninformed failure to call Ejinio was deficient,
    and we must consider whether that deficiency prejudiced the
    defense, a subject we will address below. (See Wiggins, at
    pp. 535–536.)
    Similar considerations come into play when evaluating
    Shinn’s failure to interview or call as a witness Irma. The
    Attorney General argues it was reasonable for Shinn not to call
    her because he had been unable to interview her before trial.
    But the reason Shinn did not interview Irma before trial is that
    he did not make a timely effort to do so. Shinn’s belated
    investigation of potential eyewitnesses is no justification for not
    presenting potentially exculpatory evidence. It is, rather, a
    mark of counsel’s unprofessional performance. (See Wiggins v.
    
    Smith, supra
    , 539 U.S. at pp. 522–523, 527–528; 
    Strickland, supra
    , 466 U.S. at pp. 690–691.)
    The referee identified two additional considerations that
    could have weighed against calling Irma to testify. Like Ejinio,
    she was affected by witnessing the shooting. The referee found
    her emotional state was heightened by the fact that she was
    pregnant at the time. And while she was older than her brother,
    her contemporaneous description of the shooting contained
    several discrepancies when compared with the testimony of
    other witnesses that might have been fodder for impeachment
    on cross-examination. Irma told police the day after the
    shooting that the “driver punched the officer in the face and
    pulled the officer’s gun from its holster and shot the officer in
    the neck. The driver then shot the officer two more times and
    the officer fell backwards. As the car was leaving someone
    27
    In re GAY
    Opinion of the Court by Kruger, J.
    inside the car threw the gun out of the passenger side window,
    and it landed three feet away from the officer lying on the
    ground.” The referee concluded: “While her descriptions of the
    shooter as a dark complected male Negro and the light skinned
    passenger are helpful to petitioner, her recollection of events is
    largely inconsistent with that of the other witnesses. These
    discrepancies call into question the value and weight of her
    testimony.”
    Again, competent counsel, having interviewed Irma,
    might have chosen not to call her. But Shinn never met with
    Irma and so could not have made a strategic judgment that her
    testimony would have hurt more than it would have helped. (Cf.
    Burger v. Kemp (1987) 
    483 U.S. 776
    , 794 [defense strategy
    “supported by reasonable professional judgment” where counsel
    at least “interview[ed] all potential witnesses who had been
    called to his attention”].) Certainly, inconsistencies did not
    prevent the prosecution from relying on the testimony of
    eyewitnesses (even children), or the jury from crediting such
    testimony. (See 
    Cummings, supra
    , 4 Cal.4th at pp. 1260–1263
    [discussing the many internal discrepancies in the testimony of
    the prosecution’s eyewitnesses].) As with Ejinio, there is a
    reasonable probability competent counsel would have called
    Irma, and so we must consider as part of the prejudice flowing
    from Shinn’s limited investigation the impact of her potential
    testimony. (See Wiggins v. 
    Smith, supra
    , 539 U.S. at p. 536.)
    2.
    During the guilt phase trial, Los Angeles County Sheriff’s
    Deputy Michael McMullan testified that he and Sergeant
    George Arthur were escorting Cummings when he admitted
    killing Officer Verna, saying: “ ‘I put six in him.’ ” (Cummings,
    28
    In re GAY
    Opinion of the Court by Kruger, 
    J. supra
    , 4 Cal.4th at p. 1265.) Another sheriff’s deputy, Rick
    McCurtin, testified that on a separate occasion he overheard
    Cummings tell another inmate that he had shot Officer Verna
    twice in the back, adding: “ ‘Then we put four more.’ ” (Id. at
    p. 1266.)   Deputy Sheriff David LaCasella testified that
    Cummings admitted to putting the first shot in Officer Verna.
    (Ibid.) While this testimony inculpated Cummings, Gay argues
    that Shinn should have called additional sheriff’s deputies who
    heard Cummings confess that he alone killed Officer Verna and
    who could have exculpated Gay. We consider two potential
    witnesses, Deputies William McGinnis and Richard Nutt.
    In October 1984, Deputy McGinnis was escorting
    Cummings when Cummings became upset with McGinnis and
    threatened him. When McGinnis told Cummings that at least
    he, McGinnis, had never shot anyone in the back, Cummings
    responded: “ ‘[w]ell, I put two in front of the motherfucker, and
    he wouldn’t have got three in the back if he hadn’t turned and
    ran, coward punk-ass motherfucker.’ ” (Gay I
    I, supra
    , 42
    Cal.4th at p. 1214.) McGinnis recorded this statement the same
    day in a report he submitted to the prosecutor, which was
    disclosed to Shinn in discovery. McGinnis also testified to the
    conversation during an Evidence Code section 402 hearing
    outside the presence of the jury, during which Cummings sought
    unsuccessfully to prevent McMullan’s, McCurtin’s, and
    McGinnis’s statements from being admitted. Shinn was present
    during that hearing and thus aware of McGinnis’s testimony.
    The Attorney General concedes Shinn never interviewed
    McGinnis and, when the prosecution did not call McGinnis, did
    not have McGinnis testify on Gay’s behalf.
    The referee concluded Deputy McGinnis’s testimony
    “would have been helpful to petitioner.” We agree. McGinnis’s
    29
    In re GAY
    Opinion of the Court by Kruger, J.
    testimony would have directly supported Gay’s defense that
    Cummings was the sole shooter and fired the final shots into
    Officer Verna. And as a peace officer with no evident incentive
    to see the killer of a fellow officer escape punishment, McGinnis
    would have been among the most credible witnesses Gay could
    have called in support of his defense.
    The referee thought the value of the statement was limited
    because Cummings’s statement “was lacking in detail as to the
    identity of the shooter.” In context, however, Cummings’s
    statement is best understood as an acknowledgment that
    Cummings alone shot Officer Verna. Cummings made the
    statement in response to Deputy McGinnis’s assertion that
    McGinnis, unlike Cummings, had never shot anyone in the
    back. Rather than deny that he had shot Officer Verna in the
    back (e.g., because it was Gay who had fired the final shots),
    Cummings justified doing so, explaining that Verna wouldn’t
    have gotten shot in the back if he hadn’t tried to run. Deputy
    McGinnis himself understood the statement in just this way. In
    a 2003 declaration, McGinnis said: “It was clear to me then as
    it is now that Cummings alone pulled the trigger and was the
    sole person responsible for killing Officer Verna.” Had he been
    called at trial, McGinnis could have testified to his
    understanding of what Cummings meant.9 We recognize that
    the form of Cummings’s statement may not eliminate all
    possible ambiguity, but it would have been more than
    reasonable for the jury to interpret the statement as Deputy
    9
    The Attorney General concedes that “[t]he context and
    substance of Cummings’s admissions made ‘clear to [Deputy
    McGinnis] . . . that Cummings alone pulled the trigger and was
    the sole person responsible for killing Officer Verna.’ ”
    30
    In re GAY
    Opinion of the Court by Kruger, J.
    McGinnis did—as an admission of sole responsibility for the
    shooting.
    The referee also concluded that testimony from Deputy
    McGinnis would have been “cumulative to the testimony of
    Michael McMullan and Rick [McCurtin].” But Deputy McGinnis
    was not a witness to confessions the jury had already heard
    about; his testimony would have detailed an entirely different
    occasion on which Cummings confessed, in a way that clearly
    supported the defense theory that Cummings was the sole
    shooter. Deputy McCurtin’s testimony suffered from the
    difficulty that saying “ ‘we’ ” put four more in Officer Verna did
    not sound like an admission of sole responsibility for the
    shooting. (See 
    Cummings, supra
    , 4 Cal.4th at p. 1266 & fn. 9,
    italics omitted.)    Cummings’s confession to McGinnis, in
    contrast, was understood by McGinnis as just such an
    admission. We can think of no tactical reason why competent
    counsel would, in a case where codefendants pointed the finger
    at each other for the murder of a law enforcement officer, pass
    up the opportunity to present testimony from a second peace
    officer that placed sole responsibility on the other defendant.
    In 1984, Los Angeles Sheriff’s Deputy Richard Nutt was
    tasked with escorting Cummings to the shower. According to
    the referee’s findings, Cummings said to Nutt, “ ‘Hey Nutt. I
    killed Verna. He had about sixteen years on. When I get out of
    prison you will have about sixteen years on and I will kill you
    too.’ ” Nutt replied, “ ‘You’re a coward. I know you shot Verna
    in the back. If you want to take a shot at me, do it to my face.’ ”
    Cummings did not respond. Deputy Nutt reported the exchange
    to his “supervisor, Sergeant George Arthur, who declined to take
    a formal report due to the number of similar comments made by
    Raynard Cummings to other Sheriff’s personnel.” Like Deputy
    31
    In re GAY
    Opinion of the Court by Kruger, J.
    McGinnis, Sergeant Arthur was identified “in reports compiled
    by the investigating officers and provided to the defense in
    discovery materials.”
    There appears to be no dispute that as with Deputy
    McGinnis, Shinn never met, directly or indirectly, with Sergeant
    Arthur or Deputy Nutt. The referee found that “Nutt’s
    testimony would not have been available to Shinn in 1985 as his
    contact with the persons accused [of] the killing of Officer Verna
    did not come to light until at or near the time of the 2000 retrial.”
    Gay takes exception to this finding. He argues that had Shinn
    interviewed Sergeant Arthur, Nutt’s supervisor, it is reasonably
    likely he would have learned of the exchange Deputy Nutt had
    with Cummings.
    We decline to adopt the referee’s finding that Deputy
    Nutt’s testimony would have been unavailable to Shinn. True,
    “the duty to investigate does not force defense lawyers to scour
    the globe on the off chance something will turn up; reasonably
    diligent counsel may draw a line when they have good reason to
    think further investigation would be a waste.” (Rompilla v.
    
    Beard, supra
    , 545 U.S. at p. 383.) But Nutt’s testimony was
    discoverable with minimal effort. As the referee found, Nutt
    reported Cummings’s confession to Sergeant Arthur. As the
    referee also found, Shinn was provided with Sergeant Arthur’s
    name in discovery as a witness to Cummings’s jailhouse
    confessions.
    Gay was charged with the murder of a police officer. In
    such a case, peace officers would have had every incentive to
    ensure that those responsible were convicted. Exculpatory
    testimony from a peace officer would have been some of the most
    persuasive evidence a defense attorney could present. Through
    32
    In re GAY
    Opinion of the Court by Kruger, J.
    discovery, Shinn was aware of evidence that Cummings freely
    confessed to the shooting. The professionally appropriate
    response to this information would have been to contact each
    peace officer mentioned as having had contact with
    Cummings—including Sergeant Arthur—to ask about any
    confessions they had witnessed or knew of and to solicit evidence
    that Cummings, alone, killed Officer Verna.             Such an
    investigation would have, in all likelihood, uncovered
    Cummings’s confession to Deputy Nutt.
    The Attorney General argues that Deputy Nutt would
    have been readily impeached because he told homicide
    investigators in 2000 that it was Gay whom he escorted to the
    showers and who confessed to killing Officer Verna. The written
    report prepared by detectives who interviewed Nutt then does
    indicate the speaker was Kenneth Gay, but at the reference
    hearing Nutt identified a booking photo of Cummings and
    testified adamantly and at length, on direct and on cross-
    examination, that the detectives had misunderstood his
    statements as relating to Gay, whom he had never met. The
    referee credited this testimony and concluded it was Cummings
    who confessed to and threatened Nutt. The 2000 written report
    gives no reason to think Nutt, if called to testify at the 1985 trial,
    would have had any doubt it was Cummings with whom he
    spoke.
    Shinn’s defense of Gay relied in part on highlighting
    prosecution testimony that Cummings confessed to shooting
    Verna. Calling additional such witnesses, witnesses who could
    support the theory that Cummings alone shot Verna, would
    have been fully consistent with Shinn’s strategy. Given the
    potential value of peace officer testimony, we can conceive no
    tactical reason why competent counsel would have declined to
    33
    In re GAY
    Opinion of the Court by Kruger, J.
    investigate the availability of such witnesses and instead simply
    relied on whichever witnesses the prosecution chose to call.
    Shinn’s performance in failing to investigate this line of defense
    was deficient. (See In re 
    Lucas, supra
    , 33 Cal.4th at pp. 725–
    731.)
    D.
    Taken alone, these deficiencies would be troubling
    enough. But the specific instances of Shinn’s failure to
    competently pursue Gay’s defense must be considered in their
    broader context—namely, the context of an attorney-client
    relationship poisoned at its root by fraud. As we explained in
    our previous opinion and discussed above, Shinn used deception
    to insinuate himself into the representation of Gay, who was
    originally represented by the public defender.10 An earlier
    reference hearing established the following: “ ‘While Petitioner
    was in county jail in late June, 1983, Shinn and Marcus
    McBroom introduced themselves to Petitioner. McBroom
    identified himself as a minister and told Petitioner that he
    represented a group of black businessmen that wished to hire a
    lawyer for Petitioner. McBroom was an ordained minister. Both
    Shinn and McBroom encouraged Petitioner to retain Shinn.
    Petitioner said he had no money to retain counsel and Petitioner
    was told not to worry [because] this group of black businessmen
    would take care of Shinn’s fee. [¶] Shinn never quoted a fee,
    was paid a fee, or attempted to collect a fee from the alleged
    10
    We did not ask the referee additional questions about this
    initial fraud; the relevant facts had already been established in
    an earlier reference hearing in connection with Gay’s first
    habeas corpus petition. (See Gay 
    I, supra
    , 19 Cal.4th at pp. 794–
    795.)
    34
    In re GAY
    Opinion of the Court by Kruger, J.
    group of businessmen. [¶] There is no evidence to cause this
    Court to believe that there ever was any group of “black
    businessmen” to pay Shinn’s retainer.          Shinn later told
    Petitioner to tell the court that his parents had paid a retainer
    to Shinn. This was not accurate. Shinn never had any
    reasonable belief that he would be paid by any group of
    businessmen or Petitioner’s family. Shinn’s intent from early
    on was to seek appointment by the Court.’ ” (Gay 
    I, supra
    , 19
    Cal.4th at p. 794.) There were no exceptions to these findings,
    which were amply supported by the record, and we adopted
    them, concluding: “Shinn engineered both his initial retention
    and subsequent appointment by fraudulent means.” (Id. at
    p. 795.)
    Thus, from the very outset, Shinn showed himself willing
    to deceive Gay (and the court) to further his own personal ends.
    The duty of loyalty is “perhaps the most basic of counsel’s
    duties.” 
    (Strickland, supra
    , 466 U.S. at p. 692.) Shinn’s
    stunning breach of professional norms casts doubt on the usual
    assumption that counsel thereafter assumed and fulfilled this
    duty, acting in Gay’s best interests and ensuring the
    prosecution’s case would be subject to the requisite adversarial
    testing.11 (See Gay 
    I, supra
    , 19 Cal.4th at pp. 831–834 (conc.
    opn. of Werdegar, J.).)
    11
    Recommending Shinn be disbarred on unrelated grounds
    several years later, the State Bar Court concluded “Shinn ‘lacks
    basic understanding of the most fundamental responsibilities of
    an attorney as embodied in the provisions of the Business and
    Professions Code and the Rules of Professional Conduct.’ ” (Gay
    
    I, supra
    , 19 Cal.4th at p. 780, fn. 5, quoting In the Matter of
    Shinn (Review Dept. 1992) 2 Cal. State Bar Ct. Rptr. 96, 107.)
    35
    In re GAY
    Opinion of the Court by Kruger, J.
    Our evaluation as to whether Gay’s conviction was the
    product of a reliable proceeding also takes into account the
    referee’s findings concerning a second potential conflict of
    interest. In an unrelated eminent domain action, Shinn
    obtained a judgment of nearly $200,000 for his clients Oscar and
    Marjorie Dane. The Danes refused to accept the funds, believing
    their property was worth substantially more. Although the trial
    court ordered Shinn to keep the funds in an interest-bearing
    trust account for the benefit of the Danes, Shinn failed to do so.
    He instead loaned $50,000 of these funds to one person, wrote a
    check for $2,000 to another, and used $70,000 to make
    restitution to a previous set of clients from whom he had
    misappropriated money, Alexander and Rebecca Korchin.
    The Danes contacted the Major Frauds Division of the Los
    Angeles County District Attorney’s Office to complain that the
    City of Santa Monica had stolen their home. Deputy District
    Attorney Albert MacKenzie and Los Angeles County Sheriff’s
    Department Detective Charles Gibbons determined an eminent
    domain judgment had been entered but no money paid to the
    Danes. On March 1, 1984, after Shinn had begun representing
    Gay, MacKenzie and Detective Gibbons met with Shinn at the
    Criminal Courts Building in downtown Los Angeles and asked
    Shinn for an accounting of the Danes’ funds. Eventually, in
    1985, the Danes were persuaded to accept nearly $180,000 from
    Shinn. Had Shinn invested the Danes’ funds in an interest-
    bearing account as the court had ordered, “the Danes would
    have received substantially more.” MacKenzie declined to file
    criminal charges against Shinn and the case was closed in 1987.
    MacKenzie testified: “ ‘I could never reach a point where I had
    . . . what I considered . . . a provable embezzlement.’ ” Thus,
    throughout Gay’s trial, Shinn was the subject of an open
    36
    In re GAY
    Opinion of the Court by Kruger, J.
    investigation by the same prosecutor’s office that was charging
    his client. He should have reported the investigation to Gay and
    to the trial court; there is no record that he ever did.
    The right to the assistance of counsel secured by the Sixth
    Amendment to the federal Constitution and article I, section 15,
    of the California Constitution “includes the correlative right to
    representation free from any conflict of interest that
    undermines counsel’s loyalty to his or her client.” (People v.
    Doolin (2009) 
    45 Cal. 4th 390
    , 417; see Wood v. Georgia (1981)
    
    450 U.S. 261
    , 271.) Whether being the subject of an active
    embezzlement investigation created an actual conflict of
    interest and deprived Gay of his right to the effective assistance
    of counsel depends on “whether counsel ‘pulled his punches,’ i.e.,
    whether counsel failed to represent defendant as vigorously as
    he might have, had there been no conflict” (People v. Cox (2003)
    
    30 Cal. 4th 916
    , 948) and whether Gay was prejudiced thereby
    (Doolin, at pp. 418–421).
    The referee thought this unlikely. As the referee noted,
    the Los Angeles County District Attorney’s Office is a massive
    office; the prosecutor who tried Gay’s case was not acquainted
    with the prosecutor who investigated Shinn; and there is no
    indication that the trial prosecutor in this case was aware that
    Shinn was being investigated by another part of the district
    attorney’s office. For these reasons, the referee concluded:
    “Whatever deficiencies or shortcomings may have resulted from
    Shinn’s representation of petitioner during the 1985 guilt phase
    trial, none can be linked to the embezzlement investigation or
    characterized as an attempt to curry favor with the
    prosecutors.”
    37
    In re GAY
    Opinion of the Court by Kruger, J.
    We agree with the referee that the evidence establishes no
    firm link. And because Shinn was not available to testify at the
    reference hearing, we have no way to know to what extent his
    concerns about the embezzlement investigation may or may not
    have affected his performance in Gay’s case. But given the
    history of the representation, we cannot entirely disregard the
    referee’s underlying findings. (See Gay 
    I, supra
    , 19 Cal.4th at
    p. 828 [the fraud at the inception of the relationship and the
    embezzlement investigation both “contribute to our lack of
    confidence in the verdict when considered with Shinn’s other
    failings”].) Those findings establish that after committing fraud
    to obtain representation of Gay, Shinn was soon under
    considerable personal pressure to avoid prosecution by the same
    prosecutor’s office and financial pressure from the looming need
    to make restitution to other clients. Shinn defaulted on his
    obligation to inform his client, as well as the court. Although we
    cannot definitively link Shinn’s deficiencies and shortcomings to
    the pending embezzlement investigation, collectively the
    circumstances surrounding Shinn’s representation of Gay
    reinforce our conclusion that Gay did not receive the benefit of
    the assistance of competent counsel loyal foremost to his
    interests.
    E.
    To obtain relief, Gay must demonstrate “a reasonable
    probability that, but for counsel’s unprofessional errors, the
    result of the proceeding would have been different. A reasonable
    probability is a probability sufficient to undermine confidence in
    the outcome.” 
    (Strickland, supra
    , 466 U.S. at p. 694; accord,
    People v. Rices (2017) 4 Cal.5th 49, 80; Gay 
    I, supra
    , 19 Cal.4th
    at p. 790.) Where, as here, counsel’s performance has been
    shown to be deficient in multiple respects, we do not consider
    38
    In re GAY
    Opinion of the Court by Kruger, J.
    each error in isolation. We instead consider the cumulative
    impact of the errors on the fairness of the trial. (See Gay I, at
    p. 826.)    How readily deficient performance undermines
    confidence in the trial’s outcome will in part depend on the
    strength of the trial evidence on any decisive points. A “verdict
    or conclusion only weakly supported by the record is more likely
    to have been affected by errors than one with overwhelming
    record support.” (Strickland, at p. 696.)
    An analysis of prejudice under Strickland does not involve
    the application of “mechanical rules.” 
    (Strickland, supra
    , 466
    U.S. at p. 696.) Instead, “the ultimate focus . . . must be on the
    fundamental fairness of the proceeding whose result is being
    challenged. In every case the court should be concerned with
    whether, despite the strong presumption of reliability, the result
    of the particular proceeding is unreliable because of a
    breakdown in the adversarial process that our system counts on
    to produce just results.” (Ibid.) We have previously concluded
    that “the cumulative impact of Shinn’s many failings,” both his
    potential conflicts and his specific deficiencies at the penalty
    phase, undermined our faith in the jury’s penalty verdict. (Gay
    
    I, supra
    , 19 Cal.4th at p. 826.) Today, considering the impact of
    specific additional instances of deficient performance in the light
    of those same conflicts and misfeasance, we conclude Shinn’s
    many failings critically undermine our faith in the jury’s guilt
    phase verdict as well.
    We begin with Shinn’s decision to advise Gay to confess to
    his involvement in a series of robberies, for no evident strategic
    reason and without a firm deal in place that would have
    prevented the prosecution from introducing the confessions
    against him at trial. (See ante, at pp. 16–18; Gay 
    I, supra
    , 19
    Cal.4th at pp. 791–792.) Examining the likely effect on the
    39
    In re GAY
    Opinion of the Court by Kruger, J.
    sentence Gay received, we explained in Gay I: “The prejudicial
    impact at the penalty phase of the admission of petitioner’s
    statement confessing to the robberies cannot be understated.
    Shinn not only acted as a second prosecutor by creating the
    evidence that led to petitioner’s conviction of the robberies, his
    conduct permitted the prosecutor to portray petitioner as an
    admitted serial robber who killed a police officer to avoid arrest
    and prosecution for the robberies. That picture of defendant,
    absent any substantial mitigating evidence, would be
    devastating to any hope for a sentence less than death.” (Gay I,
    at pp. 793–794.)
    The effect at the guilt phase would likewise have been
    considerable. Among the robbery victims, only a single one
    identified Gay as a participant. (See 
    Cummings, supra
    , 4
    Cal.4th at pp. 1306–1311.) In the absence of Gay’s confessions,
    the prosecution would have had to rely principally on the
    testimony of Pamela Cummings, who asserted Gay was a
    confederate (see ibid.) but was impeachable based on her
    incentive to minimize her own and her husband’s culpability for
    the robberies, as well as her husband’s involvement in the
    murder.12 Instead, the prosecution was able to rely on Gay’s
    own admission that he participated in the series of armed
    robberies, and to replace any doubt that Gay and Cummings
    acted as a team with certainty. (See Gay 
    I, supra

    corroboration [of Pamela Cummings]. The statement Shinn
    incompetently elicited from petitioner made the prosecution’s
    case.”].) The taped confessions, played for the jury, portrayed
    Gay through his own words as an active participant and a man
    of violence, someone who modified a knife’s handle to improve
    its grip and make it easier to use, generally carried a gun, and
    even broke his .32-caliber handgun on the head of one
    unfortunate robbery victim.
    In turn, that crime spree participation formed the
    centerpiece of the prosecution’s argument that Gay also shot
    Officer Verna and that the shooting was premeditated. (See
    
    Cummings, supra
    , 4 Cal.4th at p. 1257; Gay 
    I, supra
    , 19 Cal.4th
    at p. 827.) In closing argument, the prosecutor explained why
    Gay had a motive equal to Cummings. He speculated that
    Cummings and Gay surely would have had “conversations over
    a period of weeks when they are doing the robberies. [¶] If you
    are responsible for as many robberies as these men were, that
    subject has got to come up. [¶] ‘What are we going to do if we
    run into the police?’ Because now they were committing some
    [crimes] and the reason they have to discuss it is kind of logical.
    [¶] Maybe it is not something you spend any amount of time
    thinking about, but if you do it, it makes sense th[a]t they talk
    about it. Here’s why. [¶] Two people doing these robberies. If
    one of them is going to violently resist the police and shoot his
    way out, the other one has to be willing to do the same thing.
    [¶] If one of them isn’t going to do any shooting and he says,
    ‘Oh, no. If the police get me, I am going to surrender,’ [then] the
    other one has to do the same thing. [¶] They have to coordinate.
    [¶] It wouldn’t make any sense for one of them to react one way
    and the other one to react the other way. [¶] Imagine the man
    says I am not going to shoot my way out, I am going to surrender,
    41
    In re GAY
    Opinion of the Court by Kruger, J.
    turns to his partner and says, what are you going to do? [¶] He
    says, ‘I am going to shoot my way out.’ [¶] So in this case, they
    both decide to shoot.” Describing Gay’s motive, the prosecutor
    asked the jury to “[i]magine how worried you would be if you
    were responsible for 17 armed robberies in the Valley. You
    would probably be frantic about it.”         The murder was
    premeditated because “with all these robberies being
    committed, it is obvious that [Cummings and Gay] had to plan
    what their response would be, and in fact they killed Paul Verna
    in accordance with that plan.”
    True, “[t]he evidence of motive was not limited to evidence
    of the robberies of which Gay was convicted, but included
    evidence of the joint commission of another robbery, evidence
    that the car used by defendants was stolen, and evidence of
    parole violation.” (
    Cummings, supra
    , 4 Cal.4th at p. 1324.) But
    even if the prosecutor could have argued about Gay’s motive to
    escape law enforcement detection, the argument would have
    been considerably weaker had Gay not confessed to his role in
    the lengthy series of armed robberies of which the jury would
    later convict him. It is unsurprising, then, that the prosecution
    chose to place principal reliance on Gay’s admission to
    committing the series of charged robberies with Cummings as
    the basis for its theory that Gay and Cummings agreed to shoot
    their way out rather than allow themselves to be captured.
    Shinn’s decision to have Gay meet with and confess to the
    prosecution had other collateral consequences. As part of the
    defense case, Shinn called Detective Holder to testify concerning
    Gay’s interview. In the course of direct examination, Shinn
    elicited from Holder his belief that Gay was telling the truth
    when he confessed to the robberies but was lying as to the other
    matters discussed that day, i.e., participation in the Verna
    42
    In re GAY
    Opinion of the Court by Kruger, J.
    murder. According to Holder, Detective Helvin and the
    prosecutor shared these views. (See 
    Cummings, supra
    , 4
    Cal.4th at pp. 1269, 1340.) Shinn thus exacerbated the impact
    of the confessions by putting before the jury evidence that any
    Gay denial of participation in shooting Officer Verna was a lie.
    Moreover, by “falsely assuring [Gay] that the statement
    would not be admissible at trial” (Gay 
    I, supra
    , 19 Cal.4th at
    p. 781), Shinn severely damaged the attorney-client
    relationship and Gay’s ability to trust Shinn and assist in his
    ongoing defense. The court’s ruling that the confessions could
    be admitted left Gay “believ[ing] that Shinn had not acted in
    Gay’s best interest” and that “Shinn had deceived Gay”
    concerning discussions with the prosecution. (
    Cummings, supra
    , 4 Cal.4th at p. 1319.) Gay sought without success to
    dismiss Shinn. (Cummings, at pp. 1319–1321.) Thereafter, Gay
    was represented by an attorney in whom he could place little
    confidence.
    In the absence of physical evidence, eyewitness testimony
    describing the shooting was central to each side’s case. Alone
    among the witnesses at trial, Oscar Martin identified
    Cummings as the sole shooter. (
    Cummings, supra
    , 4 Cal.4th at
    p. 1259; see 
    id. at pp.
    1259–1263.) Had they testified, Ejinio and
    Irma Rodriguez could have provided testimony that also pointed
    to Cummings as the sole shooter.13 Crucially, they also could
    have offered an explanation for why other eyewitnesses seemed
    13
    As discussed ante at pages 24 to 26, we find a reasonable
    probability competent counsel would have called both to testify.
    We thus must consider at the prejudice stage of our analysis
    what the impact of this testimony would have been. (See
    Wiggins v. 
    Smith, supra
    , 539 U.S. at pp. 535–536.)
    43
    In re GAY
    Opinion of the Court by Kruger, J.
    to think Gay had fired some of the shots. After the shooter got
    back in the car, both saw the car drive off but then return shortly
    and a second lighter skinned man in a lighter shirt (by inference,
    Gay) get out and retrieve a gun. Their testimony would have
    supported an argument that those who thought Gay was a
    shooter had indeed seen him outside the car, with a gun, near
    Verna, and thus erroneously inferred he had fired some of the
    shots. No witness at trial identified Cummings as the shooter
    and Gay getting out only after all the shots had been fired. In
    the absence of such testimony, Shinn was left to argue that the
    majority of eyewitnesses, who testified Gay fired the final shots,
    were simply mistaken. We have previously recognized Ejinio’s
    and Irma’s testimony would have “substantially bolstered” the
    theory that Gay was not a shooter when holding that the trial
    court erred in excluding it from the 2000 penalty retrial. (See
    Gay I
    I, supra
    , 42 Cal.4th at p. 1224; see also 
    id. at p.
    1216.)14
    The case that Cummings was the sole shooter would
    similarly have benefited from the testimony of peace officers
    who heard Cummings confess.         The peace officers the
    prosecution called mostly described statements that could
    14
    At oral argument, the Attorney General stressed that
    Ejinio and Irma were farther away from the shooting than
    prosecution witnesses such as Robert Thompson. But they were
    at the very same location as Shannon Roberts, and at a similar
    distance as Shequita Chamberlain and Rose Marie Perez, each
    of whom the prosecution called. Nor did closer eyewitnesses
    necessarily have a better vantage. Thompson, the closest
    witness, was on a ladder across the street facing away from the
    traffic stop. After the first shot, he testified he got down off the
    ladder, sought out a safe place, and only looked back after
    finding shrubbery to hide behind. Witnesses farther away were
    not impaired by the need to attend to personal safety.
    44
    In re GAY
    Opinion of the Court by Kruger, J.
    equally point to Gay as a shooter. In particular, Deputy
    McCurtin testified that Cummings said after he initially shot
    Officer Verna, “ ‘we put four more’ ” shots in him. (
    Cummings, supra
    , 4 Cal.4th at p. 1266.) Deputy LaCasella testified he
    “heard Cummings yell: ‘You know how he got number six[,]
    don’t you?’ Gay then replied: ‘Number six?’ Cummings said
    ‘yeh,’ and then yelled:       ‘That’s the one I put in the
    motherfucker.’ ” (Ibid.) These statements could constitute an
    admission that Cummings fired only one shot, “number 6”—the
    number assigned the gunshot wound from the very first shot by
    the deputy medical coroner who testified at trial (
    id. at p.
    1267)—and that by his silence Gay admitted firing the
    remaining five shots. In closing argument, the prosecution
    urged exactly this interpretation.
    Potential witnesses Deputy Nutt and Deputy McGinnis, in
    contrast, could have testified to statements that more clearly
    tended to exculpate Gay. (See ante, at pp. 26–31.) Deputy
    McGinnis’s testimony was among that referenced when we
    criticized the trial court at Gay’s penalty retrial for excluding
    “the far more powerful evidence that [Cummings] himself, on at
    least four occasions, had admitted firing all of the shots.” (Gay
    I
    I, supra
    , 42 Cal.4th at p. 1224.) The testimony of peace officers
    to confessions that implicated Cummings and exonerated Gay
    in the murder of a police officer is among the most compelling
    evidence Shinn could have had at his disposal, had he only
    investigated and developed it.
    These deficiencies matter more because of the state of the
    record at trial. There was no physical evidence linking Gay to
    the shooting.     (Gay I
    I, supra
    , 42 Cal.4th at p. 1226.)
    Eyewitnesses’ “versions of the events and identification of the
    shooter or shooters varied greatly.” (
    Cummings, supra
    , 4
    45
    In re GAY
    Opinion of the Court by Kruger, J.
    Cal.4th at p. 1259; see Gay II, at pp. 1226–1227.) Apart from
    discrepancies in the testimony of each eyewitness as compared
    with the testimony of the others, individual eyewitnesses told
    versions of events and made identifications that sometimes
    changed from the shooting’s aftermath to lineups to the
    preliminary hearing to trial. (See Cummings, at pp. 1259–1263;
    Gay II, at pp. 1226–1227.)15 The star witness against Gay,
    Pamela Cummings, had evident biases (Gay II, at p. 1227), was
    conceded by the prosecutor to be dishonest, and had originally
    tried to falsely implicate another man, Milton Cook, as the
    shooter until he turned up with an alibi (
    id. at pp.
    1206–1207).
    The Attorney General notes that we have had prior
    opportunities to grant Gay relief based on a claim of ineffective
    assistance of counsel at the guilt phase of his trial but have not
    yet done so. (See 
    Cummings, supra
    , 4 Cal.4th at pp. 1339–1342;
    Gay 
    I, supra
    , 19 Cal.4th at pp. 780, fn. 6, 781–782.) This is true,
    but it does not affect our evaluation of the claim he now raises.
    Gay did present a similar claim on direct appeal, but because he
    was unable to raise matters outside the record, that claim was
    necessarily incomplete. (See Cummings, at pp. 1341–1342
    [denying relief based on the inadequacy of the record].) And
    although Gay raised a guilt phase ineffective assistance claim in
    his first habeas corpus petition, the presentation was likewise
    15
    As one example, Robert Thompson identified the taller
    Black man in the backseat as the lone shooter when interviewed
    on the day of the shooting and was unable to identify Gay in a
    lineup shortly thereafter. Before a grand jury, Thompson
    repeated that the dark-skinned backseat passenger was the
    shooter. But then at the preliminary hearing and trial,
    Thompson positively identified Gay as the front-seat passenger
    who exited the car holding a gun.
    46
    In re GAY
    Opinion of the Court by Kruger, J.
    incomplete, identifying some but not all of the deficiencies that
    we address today. In particular, that petition did not plead a
    claim that Shinn was deficient for failing to investigate and
    present testimony from Ejinio Rodriguez, Deputy William
    McGinnis, or Deputy Richard Nutt. Because Gay’s earlier
    attempts to argue that he received the ineffective assistance of
    counsel at the guilt phase were raised on direct appeal and in a
    habeas corpus petition filed before our clarification of the limits
    on successive petitions (In re 
    Clark, supra
    , 5 Cal.4th at pp. 767–
    782), they do not bar relief on the more complete record he now
    presents (see In re 
    Robbins, supra
    , 18 Cal.4th at p. 788, fn. 9;
    People v. Mendoza Tello (1997) 
    15 Cal. 4th 264
    , 267).
    In light of both the specific deficiencies we have addressed
    and the deception at the inception of Shinn’s representation, we
    cannot say Gay’s murder conviction was the product of a
    trustworthy adversarial process. Defense counsel obtained
    appointment to represent Gay through fraud, counseled him to
    make damaging confessions to the prosecution without
    safeguards to ensure the confessions would not be used without
    a deal (while deceiving him as to whether such safeguards were
    in place), and failed to conduct a timely investigation into
    available testimony from eyewitnesses who would have
    exculpated Gay and peace officers who would have inculpated
    Gay’s codefendant, Raynard Cummings. Counsel turned in this
    performance in a case where the evidence at trial left open a
    nontrivial possibility that his client bore no responsibility for the
    death of the victim. And given Shinn’s manifest willingness to
    disregard fiduciary responsibilities, we cannot be entirely
    confident that even the other decisions challenged in the habeas
    corpus petition that might ordinarily fall within the very broad
    range of discretion we generally accord counsel were
    47
    In re GAY
    Opinion of the Court by Kruger, J.
    uninfluenced by Shinn’s readiness to place his own interests
    first and choose an easier, more personally beneficial path over
    the path that would best serve Gay.
    It is not inconceivable that even with the assistance of
    competent counsel, the jury might still have voted for guilt. But
    “that is not the test.” (Rompilla v. 
    Beard, supra
    , 545 U.S. at
    p. 393.) Gay has shown “that counsel’s errors were so serious as
    to deprive [him] of a fair trial, a trial whose result is reliable.”
    
    (Strickland, supra
    , 466 U.S. at p. 687.) Defense counsel’s
    multiple failings are, in combination, of sufficient gravity to
    overcome the strong presumption of reliability accorded final
    judgments and to undermine our ability to place faith in the
    jury’s determination that Gay shot Officer Paul Verna. Gay has
    demonstrated prejudice.
    IV.
    We conclude Gay has established entitlement to habeas
    corpus relief on his claim that he was denied the effective
    assistance of counsel at the guilt phase of his trial. We grant
    relief and vacate the judgment against Gay in Los Angeles
    County Superior Court Case No. A392702 insofar as it rests on
    Gay’s conviction for first degree murder. The petition’s
    remaining claims will be resolved by later order to be filed
    separately.
