    SUMMARY*
    Habeas Corpus
    The panel reversed in part and affirmed in part the district
    court’s denial of California state prisoner Joseph Shelton’s
    habeas corpus petition challenging his convictions for the
    first-degree murder of Kevin Thorpe, the second-degree
    murder of Laura Craig, kidnapping, and theft.
    The panel held that the prosecution’s suppression of a
    material part of its deal with key witness Norman Thomas
    violated Brady v. Maryland with respect to Shelton’s
    conviction for the first-degree murder of Thorpe, and ordered
    the writ granted as to that conviction. The panel explained
    that Thomas’s testimony was central to the prosecution’s case
    that Shelton premeditated and deliberated regarding Thorpe’s
    murder, and held that there is a reasonable probability that
    had the jury known of the prosecution’s serious doubts as to
    Thomas’s mental competence and of its successful efforts to
    prevent him from obtaining a competency test until after he
    testified, it would have reached a different result on that
    count. The panel concluded, in a memorandum disposition,
    that had Thomas been impeached by evidence of the secret
    deal with the prosecution regarding his competency, there is
    not a reasonable probability that the jury would have reached
    a different result with respect to Shelton’s convictions for the
    second-degree murder of Craig, kidnapping, and theft.

    OPINION
    REINHARDT, Circuit Judge:
    Joseph Shelton, who is serving 40 years to life for the
    brutal kidnapping and murder of Kevin Thorpe and Laura
    Craig in 1981, appeals from the denial of his petition for a
    writ of habeas corpus. We hold that the prosecution’s
    suppression of a material part of its deal with a key witness,
    Norman Thomas, violated Brady v. Maryland, 
    373 U.S. 83
    (1963), with respect to Shelton’s conviction for the first-
    degree murder of Thorpe and order the writ granted as to that
    conviction. Thomas’s testimony was central to the
    prosecution’s case that Shelton premeditated and deliberated
    regarding Thorpe’s murder, and there is accordingly a
    reasonable probability that had the jury known of the
    prosecution’s serious doubts as to Thomas’s mental
    competence and of its successful efforts to prevent him from
    obtaining a competency test until after he testified, it would
    have reached a different result on that count. We conclude,
    4                 SHELTON V. MARSHALL
    however, in a memorandum disposition filed along with this
    opinion that, had Thomas been impeached by evidence of the
    secret deal with the prosecution regarding his competency,
    there is not a reasonable probability that the jury would have
    reached a different result with respect to Shelton’s
    convictions for the second-degree murder of Craig,
    kidnapping, and theft. Thus, we affirm as to those counts.
    I. Background
    A. The offenses and trials
    Shelton stands convicted of the first-degree murder of
    Thorpe, the second-degree murder of Craig, two counts of
    kidnapping, two counts of theft, and two weapons charges.
    Most of the basic facts are undisputed. On January 11, 1981,
    Thorpe and Craig were driving through Madeline, California
    on the way to college when Shelton, Thomas, and Benjamin
    Silva spotted them at a gas station and subsequently abducted
    them. The three men took the couple to Shelton’s cabin,
    where Thorpe was chained to a tree while Craig was held
    inside.
    The next day, Thorpe was shot to death with a machine
    gun. At Silva’s direction, Thomas dismembered Thorpe’s
    body and the two men disposed of it in a remote location.
    Craig was murdered on the side of the road a few days later.
    She had been shot twice.
    Thomas was subsequently arrested for a probation
    violation. While in custody, Thomas told the police about the
    murders and directed them to Thorpe’s remains and other
    physical evidence of the crimes. Shelton turned himself in
    shortly thereafter, waived his rights, and gave a series of
    SHELTON V. MARSHALL                                 5
    partially inculpatory though sometimes inconsistent
    statements to the police. He also led them to Craig’s remains.
    At Shelton’s trial, the State’s evidence consisted primarily
    of Thomas’s testimony, Shelton’s own statements to
    investigators, and a series of notes passed between Shelton
    and Thomas while the two were in jail.1 The defense case
    consisted of Shelton’s testimony that he had been present
    during the crimes but that he was intoxicated on various drugs
    and alcohol, did not willingly participate, and feared that if he
    resisted or tried to leave, Silva would kill him and his family.2
    There was thus no dispute that Shelton was at least present
    for all of the crimes. At issue with respect to Thorpe’s
    murder—the only question we deal with in this opinion—is
    the degree of Shelton’s participation and whether he
    possessed the requisite mens rea, i.e, whether he “deliberated
    and premeditated” as required by California law for a
    conviction of first-degree murder. See infra note 13.
    At trial, Thomas and Shelton testified to different versions
    of the crimes. In both versions, Silva was the primary
    instigator. Their testimony differed greatly, however,
    1
    The jury also heard testimony about the scene of the crimes, the
    condition of the bodies, the property of the victims that was recovered, the
    weapons and other items found in the cabin and the surrounding area, and
    the local geography. None of this evidence conveyed anything about
    Shelton’s particular role in the crimes, with the exception of testimony that
    Shelton’s fingerprints were found on a car stereo taken from the victims’
    car and on sundry items in the cabin, and that he was wearing Thorpe’s
    boots when he turned himself in. None of this testimony shed any light on
    the question whether Shelton was guilty of first-degree deliberate and
    premeditated murder.
    2
    At the time of the crimes, Silva was a Hell’s Angel and a fugitive.
    Shelton and Thomas’s relationships to the Angels was less clear.
    6                 SHELTON V. MARSHALL
    regarding the degree of Shelton’s participation. According to
    Shelton, when Silva spotted the couple at the gas station and
    proposed kidnapping them, Shelton said that he “didn’t want
    no part of it.” He initially denied that the men had discussed
    kidnapping and killing people before they saw Thorpe and
    Craig, but when his recollection was refreshed with a copy of
    a statement he gave to an investigator the day after he turned
    himself in, he admitted that the three men had discussed
    kidnapping a girl a few weeks before the crimes.
    A few miles past the gas station, Silva used a red light to
    pull the couple’s car over. Shelton testified that he was with
    Silva when he purchased a light like the one used, but that it
    was purchased for an unrelated prank and he never held it
    during the kidnapping. Once the victims’ car stopped, Silva
    and Thomas ran up to it, entered it, and abducted the couple
    at gunpoint. Shelton remained in the truck in which the three
    men had arrived and followed the couple’s car to his cabin;
    he testified that he did not drive off because he believed that
    “Silva would have killed me. . . . He would have killed my
    family.” When they arrived at Shelton’s property, Silva told
    Craig and Thorpe to get on the back of the truck, which
    Shelton then drove to the cabin. Shelton then remained at the
    cabin with Craig, Thorpe, and Silva, while Thomas left for a
    short period. When Thomas returned, he and Silva took
    Thorpe outside, and he later told Shelton that they had
    chained Thorpe to a tree. Silva and Thomas then left until
    morning. While they were gone, Shelton gave Thorpe a
    sleeping bag.
    Shelton testified that after Silva and Thomas returned the
    next day, Silva “said he was moving [Thorpe] because he
    could be seen from the road.” Shelton, who said that he
    believed that he was unarmed, stated that he then walked with
    SHELTON V. MARSHALL                         7
    Thorpe, who was still chained, up a hill, while “[Silva] took
    off . . . to get . . . some more chain and stuff.” Shelton denied
    knowing that Thorpe was being taken up the hill to be killed,
    and said that he did not speak to Thorpe while they waited
    “not [a] very long” time before Silva returned. Shelton
    testified that when Silva returned, he “heard a click and . . .
    turned around and [Silva] was standing there with a machine
    gun;” Shelton said he was halfway between Silva and Thorpe
    and “jumped behind a tree when the bullets started flying.”
    After Silva emptied a clip (thirty bullets) into Thorpe, Shelton
    said that Thorpe fell to the ground, and then Silva fired half
    of another clip into him. According to Shelton, Silva then
    “gave [Shelton] the gun and said shoot him.” Shelton
    admitted that he then fired the rest of the clip at Thorpe, but
    stated that he didn’t think that he hit him and that he “wasn’t
    aiming at him.” He said that although he had previously told
    police that he hit Thorpe in the eye, “that was something that
    stuck in my mind from something else.” Shelton stated that
    if he hadn’t shot at Thorpe, Silva would have killed him “the
    second I said no.”
    Shelton testified that in the days following Thorpe’s
    murder, he tried to protect Craig from Silva. He said that at
    one point he left the cabin with her and that they ran across a
    meadow and over a hill “when [Silva] caught us.” He also
    stated that he thought that he could talk Silva out of killing
    Craig, that at one point he had in fact talked Silva out of
    killing her, that Craig liked Shelton more than the others and
    was not afraid of him, and that she could have left at any
    time. He denied knowing that she would be killed when he
    and Silva left the cabin with her, purportedly to take her to
    see the head of the Hell’s Angels. Shelton stated that Silva
    stopped along the way to buy Craig a Pepsi and that Silva was
    very calm, leading him to believe that he would not shoot her.
    8                 SHELTON V. MARSHALL
    Silva later stopped the truck to change drivers but then
    suddenly shot Craig as he rounded the vehicle. Finally,
    Shelton testified that he was on speed, “reds, valium, and pot”
    the night of the kidnapping but that he was not intoxicated
    when Craig was killed.
    Thomas’s testimony about Shelton’s role in the crimes
    differed considerably. In his account, none of the men
    consumed any alcohol or drugs during the course of the
    criminal activities. According to Thomas, Shelton and Silva
    had discussed kidnapping people prior to the crimes and said
    that if they did so, they would have to kill them. At the
    Madeline gas station, Silva said he “wanted” Craig, and
    Shelton remarked that she was pretty. Just prior to the
    kidnapping, Thomas and Shelton swapped positions in the
    truck after Shelton declined to do the kidnapping because he
    was too well known in the area.
    Thomas testified that it was Shelton and Silva who
    chained Thorpe to the tree outside of the cabin, that it was
    Thomas who gave him a sleeping bag, and that Shelton
    became upset when Craig was left unguarded. With respect
    to Thorpe’s murder, Thomas testified that Shelton was armed
    when he left with Silva and Thorpe to go up the hill, that
    Shelton returned and told Thomas to turn on the stereo, and
    that Silva later returned and told him to turn up the
    volume—the inference being that they wanted to mask the
    sound of gunfire.
    According to Thomas, Shelton later confessed his role in
    Thorpe’s murder to Thomas, stating that he had watched
    Thorpe while Silva went to get a machine gun; that Thorpe
    cried and asked to be unchained; and that while waiting for
    Silva, Shelton told Thorpe “to look at the mountain, because
    SHELTON V. MARSHALL                                9
    it was the last thing he would see.” Thomas also said that
    Shelton told him that Thorpe’s arm was reaching up after
    Silva emptied the first clip into him, that Silva then shot him
    again, and that then “[Shelton] took the machine gun and shot
    the guy all over again.” Finally, Thomas testified that Shelton
    laughed as he recounted the murder to him.
    The jury also heard testimony regarding incriminating
    statements that Shelton made to various law enforcement
    officials after turning himself in, both via the reading of
    transcripts and officer testimony.3 In interviews on January
    31, 1981 and February 1, 1981, Shelton professed to have
    been intoxicated during the kidnapping, yet recounted details
    of the events, including that the men discussed kidnapping a
    female before the abduction. According to this testimony, he
    also stated that he was armed during the initial kidnapping,
    that he had sex with Craig in the cabin but that, unlike when
    Silva and Thomas had sex with her, his sexual acts were not
    forcible.4
    During the initial interviews on January 31 and February
    1, Shelton claimed that he was not present for Thorpe’s
    murder and that he learned about it from Thomas. A sergeant
    3
    The jury heard (or was read): (1) a transcript of an interview on
    January 31, 1981; (2) testimony from Sergeant Coulter of the Shasta
    County Sheriff’s Office about interviews on February 1, 1981 and
    February 2, 1981; (3) a transcript of an interview on February 2, 1981; and
    (4) testimony from an investigator for the California Department of Justice
    about an unrecorded interview with Shelton on February 3, 1981.
    4
    On January 31, Shelton stated in a recorded interview that he was
    “always armed” during this period in which the crimes took place. On
    February 3, he said he might have been armed during the kidnapping but
    wasn’t sure.
    10                 SHELTON V. MARSHALL
    testified that Shelton stated that while he was inside the cabin
    with Craig, “Mr. Thomas and Silva came in and told him to
    turn the music up on the stereo. And a little later they came
    back and told him to turn it up a little louder.” The sergeant
    also testified that Shelton said that before Silva and he left the
    cabin with Craig, Silva told him he was going to kill her with
    a baseball bat, and that Shelton “indicate[d] that he didn’t
    believe she had any chance to escape or leave.” Shelton’s
    account of Craig’s murder was otherwise consistent with his
    account on the stand—that Silva stopped the car to switch
    drivers, but then, without any indication of his intent to do so,
    suddenly shot Craig.
    Shelton’s story regarding Thorpe’s murder changed
    during interviews on February 2. He first denied being
    present during Thorpe’s killing. Later, in interviews on that
    day and the next, however, he admitted being present and
    recounted the Thorpe killing consistently with his trial
    testimony, except that he said nothing about what he thought
    Silva was planning to do (either when they went up the hill or
    when Silva left him with Thorpe) and he admitted that he
    “might have” been armed at the time but wasn’t sure. In these
    interviews, Shelton never gave any indication that he knew in
    advance that Silva was planning to shoot Thorpe. At trial,
    Shelton claimed that his story had changed from the initial
    interviews because he had tried to block out the Thorpe
    murder.
    During an interview on February 2, Shelton said that the
    reason he at one point took Craig across a meadow and over
    a hill was that he thought the Hell’s Angels were coming and
    that he and Silva “hadn’t come to an agreement yet as to what
    was going to happen to her.” He explained that they might
    SHELTON V. MARSHALL                             11
    make her “a prostitute, x-rated movie maker, club pass-
    around” or someone’s “old lady.”
    An investigator with the California Department of Justice
    testified, on the basis of the only unrecorded interview, that
    on February 3, 1981, Shelton stated that prior to the
    kidnapping, “there had been a conversation that if in fact [a]
    kidnapping were to take place that they might have to kill the
    victims”; that “Mr. Silva spoke of it on numerous occasions”;
    and that Silva and Shelton had purchased the red light in
    preparation for committing a kidnapping. The investigator
    also testified that Shelton told him that when he and Silva left
    the cabin with Craig, he was convinced that she would be
    murdered—about 90% sure—but “felt by his being present
    perhaps somewhat he could intercede and save her.”
    Shelton’s statements on February 2 and 3 regarding Craig’s
    murder were otherwise the same as at trial.
    The prosecution also introduced into evidence several
    notes that Shelton wrote to Thomas while the two were in jail
    subsequent to Shelton learning that Thomas was cooperating
    with the prosecution and subsequent to all of Shelton’s
    inculpatory statements to the police. The notes have no
    bearing on the issue in this appeal, as they did not discuss
    Thorpe’s murder or contain evidence of premeditation or
    deliberation.5
    5
    For example, in one note Shelton told Thomas to tell his lawyer that he
    decided to tell the truth because “Joe almost died last night, and was
    refused medical attention, and you felt sorry for me.” In another note, he
    told Thomas that “if the lawyer can’t get you off, I’ll break you out.” He
    also said that Thomas should testify that Shelton received a ride from an
    old cowboy after they saw the couple at the gas station and was not seen
    again until the crimes were over. A third note told Thomas to start
    attending bible study because it would help their case.
    12                SHELTON V. MARSHALL
    On November 17, 1981, after deliberating for two and a
    half days, the jury convicted Shelton of the first-degree
    murder of Thorpe, the second-degree murder of Craig, two
    counts of kidnapping, two counts of theft, possession of a
    machine gun, possession of a silencer, and one special
    circumstance with respect to the Thorpe murder, making
    Shelton eligible for the death penalty. Significantly, the
    verdict reflects that the jury acquitted Shelton of the charge
    of first-degree murder of Craig. After the jury declined to
    impose a capital sentence for Thorpe’s murder, the court
    sentenced Shelton to life without parole on that charge and
    fifteen years to life for Craig’s murder in the second degree
    to be served consecutively. It stayed its sentences with
    respect to the other counts. On June 27, 1984, the California
    Court of Appeal affirmed the judgment but struck the special
    circumstance in an unpublished opinion. Shelton was then
    resentenced to twenty-five years to life for the murder of
    Thorpe.
    Silva was tried after Shelton in January 1982. Thomas
    was again the principal prosecution witness. Shelton was
    called to testify, but invoked his Fifth Amendment privilege
    against self-incrimination. See Silva v. Woodford (“Silva I”),
    
    279 F.3d 825
    , 828 (9th Cir. 2002). Silva was convicted of the
    first-degree murder of Thorpe, the kidnapping and theft of
    both Thorpe and Craig, and possession of a machine gun and
    silencer. 
    Id. at 829.
    He was acquitted, however, of the murder
    of Craig. He was then sentenced to death for the murder of
    Thorpe. 
    Id. B. The
    prosecution’s secret deal with Thomas
    In 1986, Silva’s counsel learned that before Shelton’s and
    Silva’s trials, Thomas’s attorney, Rex Gay, approached
    SHELTON V. MARSHALL                      13
    Lassen County District Attorney Paul DePasquale, the
    prosecutor in both cases, and “indicated . . . that [Gay]
    believed that Mr. Thomas was either unable to cooperate in
    his own defense, or insane.” Prior to this, Gay had also
    obtained a protective order prohibiting the undersheriff from
    speaking with Thomas “based on the belief that he was
    incapable of understanding [his] rights.” Prior to the crimes,
    Thomas had suffered a severe motorcycle accident resulting
    in an extended coma, and Gay “noted a certain slowness in
    his mannerisms and a defect in his speech pattern.” Gay told
    DePasquale that he “had immediate plans to have [Thomas]
    interviewed by two psychiatrists.”
    DePasquale agreed with Gay that he would be unable to
    obtain a conviction of either Silva or Shelton without
    Thomas’s cooperation. DePasquale and Gay also agreed that
    a psychiatric analysis of Thomas would “supply ammunition
    to the defense.” They then reached a plea agreement in which
    Gay would refrain from having Thomas psychiatrically
    examined, Thomas would testify against Shelton and Silva,
    and DePasquale would drop murder charges against Thomas.
    The portion of the deal pertaining to Thomas’s mental
    competency was not disclosed to either Shelton or Silva.
    Indeed, Shelton first learned about it when he read this
    Court’s 2005 decision granting habeas relief to Silva.
    C. Subsequent procedural history
    In 2002, this Court, through a different panel of judges,
    granted Silva’s habeas claim for penalty-phase ineffective
    assistance of counsel and remanded for an evidentiary hearing
    on a Brady claim based on the prosecution’s failure to
    disclose the portion of the deal with Thomas relating to
    14                    SHELTON V. MARSHALL
    Thomas’s not undergoing a psychiatric examination.6 
    Id. at 855–56.
    On remand, the district court found that the
    prosecution had indeed made the secret deal but held that it
    was not material to the convictions (or the penalty). See Order
    Denying Claim D, Silva v. Woodford, No. 2:90-cv-03311-DT
    (C.D. Cal. Dec. 22, 2003), ECF no. 200, at 9–15; see also
    Silva v. Brown (“Silva II”), 
    416 F.3d 980
    , 984–85 (9th Cir.
    2005). In 2005, the same panel of judges of this Court
    reversed in part and ordered that the writ be granted as to
    Silva’s conviction for the murder of Thorpe, but affirmed the
    denial of relief as to the kidnapping, robbery, and firearms
    convictions. Silva 
    II, 416 F.3d at 992
    .
    On November 8, 1991, Shelton filed his first federal
    petition alleging that a post-arrest statement was unlawfully
    obtained and that the trial court erred by failing to instruct the
    jury on diminished capacity. This first petition was denied by
    the district court but never considered on the merits by this
    Court.7
    Although Silva filed a state habeas petition in 1989 based
    on the same underlying facts as the instant Brady claim,
    Shelton did not learn of the matter until he discovered, in the
    prison law library, this Court’s 2005 opinion granting relief
    to Silva. On May 4, 2006, Shelton presented the instant Brady
    6
    Silva’s filed his habeas petition prior to AEDPA’s effective date. Silva
    
    I, 279 F.3d at 831
    & n.5.
    7
    On December 16, 1992, Shelton’s first federal petition was denied in
    full by the district court. On December 15, 1993, this Court declined to
    consider the merits of the petition because Shelton failed to file a Notice
    of Appeal with respect to the December 1992 order, although he had filed
    a Notice of Appeal with respect to a November 1992 order in which the
    district court denied the petition in part and stayed it in part.
    SHELTON V. MARSHALL                               15
    claim to the California Superior Court, which denied relief in
    a written decision on August 24, 2006 stating that the secret
    agreement did not concern evidence that was “favorable to
    petitioner.” The California Court of Appeal summarily denied
    relief on November 30, 2006, as did the Supreme Court of
    California on June 13, 2007.
    Shelton filed a second federal petition raising his Brady
    claim on June 25, 2007. After the district court dismissed the
    petition as second and successive, this Court granted
    authorization to file a second petition on November 4, 2008
    on the ground that the prosecution’s deal with Thomas
    constituted newly discovered evidence. Shelton filed his
    second petition on December 17, 2008. On April 8, 2013, the
    district court denied the petition but granted a certificate of
    appealability as to the materiality of the prosecution’s
    undisclosed agreement with Thomas. Shelton appeals.
    II. Analysis
    A. Standard of Review
    Shelton’s habeas petition raising the instant Brady claim
    was filed after the effective date of the Antiterrorism and
    Effective Death Penalty Act of 1996 (AEDPA). AEDPA
    therefore applies to Shelton’s claim, although it was
    inapplicable in Silva’s case.8 Under AEDPA, a federal court
    8
    Shelton did not learn of the prosecution’s bargain with Thomas that he
    would not submit to mental examination before Shelton’s trial until some
    time following this Court’s issuance of its decision in Silva’s case in 2005.
    He asks the panel to toll the application of AEDPA based on the State’s
    misconduct in failing to advise him of its deal with Thomas even after it
    began litigating an essentially identical Brady claim in Silva’s case—as
    early as 1989. We do not reach that issue in light of our holding below.
    16                    SHELTON V. MARSHALL
    may not grant the writ based on a claim adjudicated on the
    merits by a state court unless that adjudication “resulted in a
    decision that was contrary to, or involved an unreasonable
    application of, clearly established Federal law, as determined
    by the Supreme Court of the United States; or . . . resulted in
    a decision that was based on an unreasonable determination
    of the facts in light of the evidence presented in the State
    court proceeding.” 28 U.S.C. § 2254(d). The district court’s
    denial of the writ is reviewed de novo. Lambert v. Blodgett,
    
    393 F.3d 943
    , 964 (9th Cir. 2004).
    B. Application of AEDPA
    There are three distinct elements of a Brady violation:
    First, “[t]he evidence at issue must be favorable to the
    accused, either because it is exculpatory, or because it is
    impeaching.” Strickler v. Greene, 
    527 U.S. 263
    , 281–82
    (1999). Second, “that evidence must have been suppressed by
    the State, either willfully or inadvertently.” 
    Id. at 282.
    Third,
    “prejudice must have ensued.” Id.9 The decision of the
    California Superior Court was the last reasoned state court
    decision in this case and is accordingly the subject of our
    review.10 In that decision, the court ruled only on the first
    element of Shelton’s claim—whether the suppressed evidence
    was favorable to Shelton.
    9
    The terms “prejudice” and “materiality” are used interchangeably. See,
    e.g., Silva 
    II, 416 F.3d at 985
    .
    10
    Where a state court of last resort issues a postcard denial of a habeas
    petition, the federal court “looks through” the summary denial and
    considers the last reasoned decision by a state court. Ylst v. Nunnemaker,
    
    501 U.S. 797
    , 803–04 (1991); see also Avila v. Galaza, 
    297 F.3d 911
    , 918
    (9th Cir. 2002).
    SHELTON V. MARSHALL                                 17
    The California Superior Court’s denial of Shelton’s
    habeas corpus petition on the ground that “it is difficult to
    conclude that anything favorable to petitioner was
    suppressed” is contrary to clearly established law, as
    determined by the Supreme Court. Evidence that the
    prosecution believed Thomas to be incompetent was powerful
    fodder for impeaching his testimony against Shelton. See
    Silva 
    II, 416 F.3d at 987
    . The State does not dispute that
    impeachment evidence, like exculpatory evidence, plainly
    constitutes evidence that is favorable to the accused under
    Brady’s first prong. See, e.g., United States v. Bagley,
    
    473 U.S. 667
    , 676 (1985) (“Impeachment evidence . . . as
    well as exculpatory evidence, falls within the Brady rule.
    Such evidence is ‘evidence favorable to an accused . . . .’”
    (citations omitted)).11 We hold that under clearly established
    Supreme Court precedent, Shelton satisfies the “evidence
    favorable to the accused” element of Brady error. As to the
    second element, the State concedes that it made a deal with
    Thomas requiring that his competency not be examined prior
    to his testimony against Shelton, and that it failed to disclose
    the deal to the defense.
    No state court decision has addressed the third element of
    Shelton’s Brady claim—whether the suppression of the
    impeachment evidence prejudiced him, i.e., was “material.”
    The district court applied AEDPA deference in its review of
    the materiality of the suppressed evidence because it believed
    11
    See also Banks v. Dretke, 
    540 U.S. 668
    , 691 (2004) (“Farr’s paid
    informant status, qualifies as evidence advantageous to Banks.”);
    
    Strickler, 527 U.S. at 280
    (“We have . . . held that the duty to disclose . . .
    encompasses impeachment evidence as well as exculpatory evidence.”
    (citation omitted)); Giglio v. United States, 
    405 U.S. 150
    , 154 (1972)
    (holding “nondisclosure of evidence affecting credibility falls within” the
    Brady rule).
    18                   SHELTON V. MARSHALL
    that the state court meant “material” when it said “favorable.”
    We will not read the state court opinion as meaning
    something other than what it plainly said. We accordingly
    examine the materiality question de novo. See Porter v.
    McCollum, 
    558 U.S. 30
    , 38–39 (2009); Rompilla v. Beard,
    
    545 U.S. 374
    , 390 (2005); Wiggins v. Smith, 
    539 U.S. 510
    ,
    534 (2003); see also Amado v. Gonzalez, 
    758 F.3d 1119
    ,
    1131, 1136–38 (9th Cir. 2014).
    C. Materiality
    “[The] touchstone of materiality is a ‘reasonable
    probability’ of a different result . . . . The question is not
    whether the defendant would more likely than not have
    received a different verdict with the evidence, but whether in
    its absence he received a fair trial, understood as a trial
    resulting in a verdict worthy of confidence.” Kyles v. Whitley,
    
    514 U.S. 419
    , 434 (1995). The relevant question is whether
    “the government’s evidentiary suppression ‘undermines
    confidence in the outcome of the trial.’” 
    Id. (quoting Bagley,
    473 U.S. at 678). The omitted evidence “must be evaluated in
    the context of the entire record.” United States v. Agurs,
    
    427 U.S. 97
    , 112 (1976).12
    Thomas provided “the glue that held the prosecution’s
    case [for the first-degree murder of Thorpe] together.” Horton
    v. Mayle, 
    408 F.3d 570
    , 579 (9th Cir. 2005). His “testimony
    was the only direct evidence establishing that [Shelton] had
    a premeditated plan to kill” or that he deliberated—the key
    issue with respect to whether he was guilty of first-degree,
    rather than second-degree, murder. Gonzalez v. Wong,
    12
    Once prejudice is shown under this standard, further harmless-error
    review does not apply. See 
    Kyles, 514 U.S. at 435
    .
    SHELTON V. MARSHALL                               19
    
    667 F.3d 965
    , 986 (9th Cir. 2011).13 The district court
    appreciated that there exists a “reasonable probability of a
    different result” where, had the suppressed evidence been
    disclosed, the defendant might well have been convicted of a
    different offense or a different degree of the crime. 
    Kyles, 514 U.S. at 434
    . That is, a probability of a total acquittal is not
    required to establish prejudice.
    We conclude that had Thomas’s testimony against
    Shelton been excluded as a result of the prosecution’s secret
    efforts to preclude an inquiry into his competency, there is a
    reasonable probability that the jury would not have found
    Shelton guilty of deliberate and premeditated first-degree
    murder—that the outcome of the proceeding would have been
    different. Certainly, viewing the record as a whole we cannot
    be confident that the verdict would have been the same. We
    13
    The jury was instructed that first-degree murder was either:
    (1) “murder which occurs during the commission or attempt to commit the
    crime of robbery,” or (2) “murder which is perpetrated by any kind of
    willful, deliberate and premeditated killing.” The verdict reflects that the
    jury convicted Shelton of the first-degree murder of Thorpe based on the
    latter theory and rejected the former.
    Although we hold in a memorandum disposition filed concurrently
    with this opinion that the evidence, apart from Thomas’s testimony
    regarding Shelton’s intentional participation in the kidnapping of Thorpe
    and Craig, precludes a finding of a reasonable probability of a different
    outcome on the kidnapping counts, at the time of trial kidnapping was not
    a predicate offense for first-degree felony murder. Rather, murder
    occurring in the course of a kidnapping was punishable as second-degree
    murder only. See Cal. Penal Code § 189 (West 1970 & Supp. 1988). In
    1990, Proposition 115 amended section 189 to include kidnapping as a
    predicate offense for first-degree felony murder. See Cal. Penal Code
    § 189 (West Supp. 1999) (“Historical and Statutory Notes”); People v.
    Davis, 
    896 P.2d 119
    , 146 & n.11 (Cal. 1995). The amendment did not
    apply retroactively, however. See 
    id. 20 SHELTON
    V. MARSHALL
    do not rely on the possibility that Thomas’s testimony was
    excludable, however, as we also hold that there was a
    reasonable probability of a different outcome had Thomas’s
    testimony been admitted and then impeached by evidence of
    the prosecution’s undisclosed deal with him.
    We cannot overemphasize the importance of
    allowing a full and fair cross-examination of
    government witnesses whose testimony is
    important to the outcome of the case. Had the
    full extent of the prosecution’s deal with
    Norman Thomas been disclosed to the
    defense, a full cross-examination of this
    critical witness would have revealed that even
    the prosecution viewed Thomas’s testimony
    with some doubt.
    Silva 
    II, 416 F.3d at 986
    –87 (internal citations and quotation
    marks omitted).
    Shelton and Thomas gave very different accounts of
    Thorpe’s murder and Shelton’s role in it, with Shelton
    asserting that he was surprised and even endangered by
    Silva’s actions, while Thomas claimed that Shelton clearly
    knew what was about to happen to Thorpe and indeed
    actively and eagerly played a part in it. According to Shelton,
    (1) he thought that he was taking Thorpe up the hill in order
    to conceal him and that Silva went to get more chains; (2) he
    did not know that Thorpe would be killed; (3) he was
    surprised when Silva opened fire on Thorpe and had to jump
    out of harm’s way himself; and (4) he shot at Thorpe only
    after Silva had already felled him with forty-five bullets (a
    clip and a half) and only because he believed that Silva would
    shoot him on the spot if he did not comply with his order. By
    SHELTON V. MARSHALL                       21
    contrast, Thomas testified that (1) Shelton guarded Thorpe
    knowing that Silva was going to retrieve a machine gun; (2)
    Shelton returned from the hill in order to turn up the
    stereo—indicating that he knew in advance that Thorpe
    would be shot and tried to conceal the sound; (3) while
    waiting for Silva’s return, Shelton told Thorpe to “look at the
    mountain, because it was the last thing he would see”; and (4)
    Shelton laughed while recounting Thorpe’s murder. Thomas
    also described Shelton as taking the gun from Silva in order
    to shoot Thorpe, rather than being ordered to do so or risk
    being shot himself.
    No other evidence corroborated this account by Thomas
    of Shelton deliberating and premeditating the killing of
    Thorpe—not Shelton’s statements to investigators, his trial
    testimony, the notes he passed to Thomas in jail, or any
    physical or forensic evidence. “[I]t was [Thomas’s tainted
    testimony alone] that revealed that [Shelton] confessed” to
    knowing in advance that Thorpe would be killed and to
    participating willingly in his execution, 
    Horton, 408 F.3d at 579
    —by far the most damning evidence heard by the jury,
    see Arizona v. Fulminante, 
    499 U.S. 279
    , 296 (1991).
    The materiality of evidence “is best understood by taking
    the word of the prosecutor.” 
    Kyles, 514 U.S. at 444
    ; see also
    Banks v. Dretke, 
    540 U.S. 676
    , 700 (2004); 
    Horton, 408 F.3d at 579
    . In his closing argument, DePasquale emphasized the
    “look at the mountain” statement, arguing that it
    demonstrated that Thorpe never had a chance to survive.
    Moreover, in entering the judgment, the trial judge cited “the
    transactions . . . of turning up the hi-fi or this loud speaker”
    as the basis of the first-degree conviction because it
    demonstrated that “Shelton had advance knowledge of the
    plan involving Thorpe” and that “the purpose of the mission
    22                 SHELTON V. MARSHALL
    at the time [was] the execution of Thorpe.” This evidence that
    the prosecutor and the district judge found central to the first-
    degree conviction came solely from Thomas—a witness
    whose testimony even the prosecution seriously doubted and
    whom it precluded from obtaining a competency
    examination.
    In Silva II, this Court explained why the very deal at issue
    in this case, had it not been illegally suppressed, would have
    severely undermined the State’s case and created “a
    reasonable probability of a different result”:
    Had the prosecution’s deal foreclosing a
    psychiatric examination of Thomas been
    revealed, it could have had a profound effect
    on the jury’s assessment of Thomas’s
    testimony. . . .The fact of the undisclosed deal
    bears critically and directly on Thomas’s
    competence and credibility as a witness. Had
    the defense known that the prosecution had
    required, as a condition of Thomas’s plea
    bargain, that he agree not to be psychiatrically
    evaluated before testifying, competent defense
    counsel would have ensured that the jury was
    made aware of the potentially devastating fact
    that the state itself doubted Thomas’s mental
    competency. . . . [T]he very fact that the
    prosecution had sought to keep evidence of
    Thomas’s mental capacity away from the jury
    might have diminished the State’s own
    credibility as a presenter of evidence.
    In sum, the fact of the prosecution’s
    undisclosed deal with Thomas, had it been
    SHELTON V. MARSHALL                         23
    presented to the jury, would have put the
    testimony of this critical witness in a
    substantially different light, both directly, by
    casting doubt on the accuracy of Thomas’s
    testimony, and indirectly, by inducing the
    defense to focus the jury’s attention on
    Thomas’s lapses and inconsistencies and by
    calling into question the prosecutor’s faith in
    the competence of his own witness.
    Silva 
    II, 416 F.3d at 987
    –88 (citations and internal quotation
    marks omitted).
    The district court nonetheless believed that the suppressed
    evidence was not material because of Shelton’s statements
    “that he accompanied Silva in walking Thorpe up the hill,
    guarded Thorpe in Silva’s absence, . . . jumped behind a tree
    to avoid being shot . . . [, and] admitted that he shot Thorpe
    with Silva’s machine gun after Silva fired one and a half clips
    into the victim.” While these statements provide
    corroboration of Shelton’s participation in Thorpe’s murder
    such that even a jury informed of the deal with Thomas might
    well have found Shelton guilty of second-degree
    murder—that is, murder in the course of a kidnapping—they
    are fully consistent with and simply form a part of Shelton’s
    explanation that he was not aware in advance of what was
    about to happen to Thorpe and thought that he was helping
    move him to a location out of the public view. Thus, the
    statements viewed in context provide little if any evidence as
    to the premeditation or deliberation required for a first-degree
    conviction. See supra note 13. Indeed, Shelton’s testimony
    that he had to jump out of the line of fire, if credited, would
    be evidence that he was surprised by Silva’s conduct, and the
    fact that Shelton told the investigators that, in fear for his own
    24                 SHELTON V. MARSHALL
    life, he fired at Thorpe after Silva had already shot him forty-
    five times does not indicate premeditation and deliberation.
    Had defense counsel been able to cross-examine Thomas
    thoroughly about the deal’s requirement that he not receive a
    psychiatric examination before testifying and explain to the
    jury that even the prosecution was concerned about his
    mental stability, if not his sanity, there is a reasonable
    probability that the jury would not have reached the verdict
    it did. Certainly, as Thomas’s evidence was the primary
    evidence upon which the prosecution relied to establish
    premeditation and deliberation, we cannot say with
    confidence that had his testimony been impeached on the
    ground of his potential mental incapacity or insanity and the
    prosecution’s unlawful deal to keep that information from the
    jury, the jury would have nevertheless returned a verdict of
    first-degree rather than second-degree murder.
    True, Shelton’s admissions that he was present for
    Thorpe’s killing, watched Thorpe while waiting for Silva, and
    shot at his body after Silva already had fired forty-five rounds
    into him, if taken in isolation, could constitute circumstantial
    evidence that he knew in advance that Thorpe would be
    killed. Nevertheless, we have held that prejudice is
    established where the concealed evidence would impeach the
    only witness to provide direct evidence of the defendant’s
    mens rea. See Hayes v. Brown, 
    399 F.3d 972
    , 985 (9th Cir.
    2005) (en banc) (finding suppressed evidence material where
    tainted witness’s testimony “was the centerpiece of the
    prosecution’s case” and “[n]early all of the other evidence
    against Hayes was circumstantial.”); see also 
    Gonzalez, 667 F.3d at 986
    ; 
    Horton, 408 F.3d at 580
    ; Benn v. Lambert,
    
    283 F.3d 1040
    , 1062 (9th Cir. 2002). We repeat: Thomas’s
    testimony supplied the only direct evidence that Shelton
    deliberated and premeditated Thorpe’s murder, as opposed to
    SHELTON V. MARSHALL                       25
    acting on Silva’s command and in fear for his life. Moreover,
    this Court has previously held the suppression of the
    prosecution’s deal with Thomas to be prejudicial in Silva’s
    case, notwithstanding physical evidence of the crime
    corroborating Thomas’s story, fingerprint analysis placing
    Silva at the scene, and Silva’s equivocating statements to the
    police post-arrest. See Silva 
    II, 416 F.3d at 984
    . See also
    Order Denying Claim D, Silva v. Woodford, No. 2:90-cv-
    03311-DT (C.D. Cal. Dec. 22, 2003), ECF no. 200, at 9–15.
    There is similarly a reasonable probability that the jury would
    have in this case reached a different verdict had Thomas been
    thoroughly impeached, notwithstanding the fact that Shelton
    admitted being present for Thorpe’s murder after having
    initially denied as much. In short, we reiterate, the
    suppression by the prosecution of its agreement with Thomas
    that he not obtain a mental examination prior to his testimony
    undermines confidence in the verdict.
    The State argues that a statement that Shelton made to an
    investigator on February 1 demonstrates the veracity of
    Thomas’s account of Thorpe’s murder and rendered his
    testimony superfluous. According to an investigator’s
    testimony, while Shelton was denying his presence at
    Thorpe’s murder in that interview, he claimed that he was in
    the cabin at the time and that Thomas told him to turn up the
    stereo. At trial DePasquale argued that this made it “almost
    obvious that [Shelton is] putting Thomas in his position and
    what he’s saying there is in essence an admission that he was
    trying to lay at Thomas’ feet an admission that he went in
    there and he said turn up that stereo.”
    This disputed statement about the stereo is not, however,
    sufficient to give us confidence in the first-degree verdict.
    The case is riddled with inconsistencies regarding who did
    26                    SHELTON V. MARSHALL
    what. Indeed, at one point, Thomas told the prosecution “that
    he was with Silva when Thorpe was killed.” Silva 
    II, 416 F.3d at 988
    (emphasis added). Moreover, the investigator who
    testified to Shelton’s statement about the stereo also testified
    that he “[didn’t] remember exactly what [Shelton] told
    [him].”14
    A comparison of the evidence against Shelton with
    respect to Craig’s murder strongly supports our conclusion
    that he was prejudiced by the State’s Brady violation. The
    jury heard evidence of premeditation and deliberation with
    respect to Craig’s murder—Shelton’s admission to the
    investigators that the men had discussed kidnapping and
    killing a girl prior to the crimes—yet it returned a verdict of
    only second-degree murder with respect to Shelton’s role in
    her killing. The State concedes that this was because of the
    jury’s “finding that there was insufficient evidence of
    deliberation or premeditation in killing Craig.” Meanwhile,
    the only direct evidence that Shelton deliberated or
    premeditated the killing of Thorpe came from a witness
    whose vulnerability to charges of incompetency or insanity
    the State felt compelled to conceal. The other evidence that
    pertained to premeditation and deliberation applied equally,
    if not more strongly, to the murder of Craig as to that of
    Thorpe. It follows that if the jury had known about the
    prosecution’s secret deal with Thomas, there is an even
    stronger probability than in Craig’s case that it would have
    returned a verdict other than first-degree murder—that it
    14
    At trial, Shelton maintained that the conversation about the stereo
    volume occurred several hours before Thorpe was taken up the hill and
    was unconnected to the killing, that he never said otherwise, and that the
    investigator either intentionally lied about what Shelton said regarding the
    stereo in the interview or mistakenly recounted an interview with Thomas.
    SHELTON V. MARSHALL                             27
    would have found insufficient evidence to conclude beyond
    a reasonable doubt that Shelton premeditated and deliberated
    as to Thorpe’s killing.15
    We reject the State’s contention that evidence of the
    prosecution’s secret deal with Thomas would have been
    cumulative to the impeachment evidence presented to the
    jury. Thomas’s accident and the fact that the prosecution had
    dropped murder charges against him in exchange for his
    cooperation were mentioned briefly during the trial.
    However, “the undisclosed evidence was not duplicative of
    the impeachment evidence actually presented, but rather was
    of a different kind. It ‘would have provided the defense with
    a new and different ground of impeachment.’” Silva 
    II, 416 F.3d at 989
    (quoting 
    Benn, 283 F.3d at 1056
    ). Evidence
    that murder charges had been dropped “could cast doubt only
    on Thomas’s forthrightness, not his competence to testify,”
    
    id. at 989,
    and the defense’s argument that Thomas “does not
    have a good memory” was far less compelling than the
    suppressed evidence that the prosecution doubted his mental
    stability to the degree that it stopped him from being
    psychiatrically examined.
    Finally, “[t]he prosecutor’s own conduct in keeping the
    deal secret underscores the deal’s importance.” Silva 
    II, 416 F.3d at 990
    . His “actions . . . speak as loud as his
    words. . . . The State’s deliberate and strategic decision to
    15
    Moreover, if the implausibility of Shelton’s claims that Craig was
    there voluntarily, even after her boyfriend had been killed, did not
    persuade the jury to find him unworthy of belief and to reject his account
    of being surprised by her murder, there is no reason to think that the
    inconsistencies in his statements would have caused it to reach a verdict
    of first-degree murder with respect to Thorpe, either.
    28                     SHELTON V. MARSHALL
    make the deal and not to disclose it suggests the weakness of
    its post hoc claims that the evidence was irrelevant.” 
    Id. If Thomas’s
    testimony was unnecessary to Shelton’s conviction
    as the State now claims, then there was no reason for it to
    take furtive actions to ensure that the jury never heard that
    both it and Thomas’s lawyer believed that he might well be
    incompetent or insane. Indeed, the deal was premised on
    DePasquale’s agreement with Gay that credible testimony by
    Thomas was necessary to obtaining a conviction of both
    Shelton and Silva.
    III. Conclusion
    In sum, the prosecution committed Brady error by
    concealing from the defense and the jury its deal precluding
    an examination of the mental competency of its star witness.
    We find this error prejudicial with respect to Shelton’s first-
    degree murder conviction in part because Thomas was the
    only witness who provided direct evidence that Shelton
    deliberated and premeditated the murder of Thorpe, and in
    part because it is the prosecution’s suppression of the
    powerful impeachment evidence that “‘undermines
    confidence in the outcome of the trial.’”

    serious doubts about the good-faith of the prosecution as a
    whole and find DePasquale’s misconduct inexcusable, the
    extremely strong evidence in the record, aside from Thomas’s
    testimony, regarding Shelton’s commission of the other
    crimes precludes us from granting relief with respect to those
    convictions.16 We leave those charges, which we address in
    the memorandum disposition filed concurrently with this
    opinion, undisturbed. The district court is directed to issue the
