    GENARO RUIZ CAMACHO, JR.,

    versus
    GARY L. JOHNSON, DIRECTOR, TEXAS DEPARTMENT
    OF CRIMINAL JUSTICE, INSTITUTIONAL DIVISION,
    Respondent-Appellee.

    Appeal from the United States District Court
    for the Northern District of Texas
    (3:95-CV-2539-G)
    __________________________________________________________________
    April 17, 1998
    Before DAVIS, JONES, and BARKSDALE, Circuit Judges.
    PER CURIAM:*
    Genaro Ruiz Camacho, Jr., a Texas death row inmate convicted
    of   capital   murder,    seeks   a   certificate   of   probable   cause   to
    challenge the district court’s denial of his petition for a writ of
    habeas corpus.    The certificate is DENIED; the stay of execution,
    VACATED.
    I.
    In 1990, Camacho was convicted and sentenced to death for the
    capital murder of David Wilburn.               During the guilt phase, as
    *
    Pursuant to 5TH CIR. R. 47.5, the Court has determined
    that this opinion should not be published and is not precedent
    except under the limited circumstances set forth in 5TH CIR. R.
    47.5.4.
    discussed infra, three eyewitnesses testified that they saw Camacho
    shoot Wilburn; and the State also presented evidence of Camacho’s
    involvement in the murders, a few days later, of Evellyn and Andre
    Banks, who had been present when Wilburn was murdered.   During the
    punishment phase, the State presented evidence that Camacho had
    committed two additional murders.
    The Texas Court of Criminal Appeals affirmed, Camacho v.
    State, 
    864 S.W.2d 524
    (Tex. Crim. App. 1993); and the United States
    Supreme Court denied Camacho’s petition for a writ of certiorari.
    Camacho v. Texas, 
    510 U.S. 1215
    (1994).
    Camacho filed a state habeas application on 20 March 1995. In
    mid-April, he moved for an evidentiary hearing; and, in mid-July,
    he requested discovery and, again, an evidentiary hearing.    On 7
    August, less than two weeks after the State filed its answer, the
    state habeas court entered findings of fact and conclusions of law
    recommending that relief be denied.       In early October, in an
    unpublished opinion, the Texas Court of Criminal Appeals adopted
    those findings and conclusions and denied habeas relief.
    Two weeks later, on 23 October 1995, Camacho filed a federal
    habeas petition, as well as a motion for stay of execution and an
    evidentiary hearing.    The district court granted the stay and
    appointed counsel.   On 24 November, the State filed an answer and
    moved for summary judgment.   On 26 December, Camacho applied for
    funds to employ experts; three days later, he moved for leave to
    conduct discovery.   In late May 1996, Camacho filed a supplemental
    application for funds to employ an expert.    On 18 July 1996, the
    - 2 -
    magistrate judge denied Camacho’s request for discovery, stating
    that the discovery sought constituted an “impermissible fishing
    expedition”.
    The magistrate judge reported findings of fact and conclusions
    of law in early January 1997, thoroughly analyzing Camacho’s claims
    in painstaking detail, and recommended that an evidentiary hearing
    was not required and that habeas relief be denied.      In late April
    1997, the district court overruled Camacho’s objections and adopted
    the findings and recommendation, with only slight revision.
    The   district   court    denied   Camacho   a   certificate   of
    appealability.    But, because Camacho filed his habeas petition
    before 24 April 1996, the effective date of the Antiterrorism and
    Effective Death Penalty Act (AEDPA), Pub. L. No. 104-132, 110 Stat.
    1214 (1996), pre-AEDPA law applies.     See Green v. Johnson, 
    116 F.3d 1115
    (5th Cir. 1997).     Camacho seeks a pre-AEDPA certificate of
    probable cause (CPC) from our court.
    II.
    In his CPC application, Camacho claims that the district court
    erred in the following ways:
    1.    By denying habeas relief on his claims
    (a)   That he was denied due process of law and a fair
    trial by the prosecution’s failure, in several instances, to
    disclose evidence favorable to the defense, in violation of Brady
    v. Maryland, 
    373 U.S. 83
    (1963);
    (b)   That he is entitled to a new trial because of newly
    discovered evidence which points directly to his innocence of the
    - 3 -
    crime for which he was convicted and that, to deprive him of his
    life without a jury’s consideration of such evidence, will deprive
    him of his life without due process of law;
    (c)        That the prosecutor’s use of peremptory challenges
    to exclude from the jury three members of minority races was based
    on racial grounds in violation of the Equal Protection Clause and
    Batson v. Kentucky, 
    476 U.S. 79
    (1986), and its progeny; and
    (d)        That he was denied his constitutional right to a
    fair trial by an impartial jury because of the admission of
    evidence relating to the murders of Evellyn and Andre Banks four
    days after the murder for which he was convicted and sentenced to
    death; and,
    2.     Concomitantly,
    (a)        By refusing to allow discovery, especially as to a
    recantation concerning the newly discovered evidence;
    (b)        By refusing to conduct an evidentiary hearing; and
    (c)        By denying funds to employ experts.
    Furthermore, except for his Batson claims, Camacho maintains
    that, because the state habeas judge neither presided over his
    capital murder trial, nor conducted an evidentiary hearing, the
    presumption       of     correctness   accorded   to   state   court   factual
    findings, pursuant to pre-AEDPA 28 U.S.C. § 2254(d), does not
    apply.    The district court applied AEDPA in denying habeas relief;
    but, as discussed, we must, instead, consider Camacho’s CPC motion
    under pre-AEDPA law.         Nevertheless, we will, for purposes of this
    opinion, assume that the presumption does not apply (except, as
    - 4 -
    discussed infra, with respect to Camacho’s Batson claims, as to
    which there are findings of fact by the trial judge).
    To obtain a CPC, a habeas petitioner must make “a substantial
    showing of the denial of a federal right”.        Lucas v. Johnson, 
    132 F.3d 1069
    , 1073 (5th Cir. 1998) (internal quotation marks and
    citation omitted).    “This standard does not require petitioner to
    show that he would prevail on the merits.”      Drew v. Collins, 
    5 F.3d 93
    , 95 (5th Cir. 1993), cert. denied, 
    510 U.S. 1171
    (1994).
    Instead, the petitioner must “demonstrate that the issues are
    debatable among jurists of reason; that a court could resolve the
    issues [in a different manner]; or that the questions are adequate
    to deserve encouragement to proceed further.” Barefoot v. Estelle,
    
    463 U.S. 880
    , 893 n.4 (1983) (emphasis in original; internal
    quotation marks and citation omitted).
    Because several of Camacho’s claims require consideration of
    the   trial   testimony   of   certain   witnesses,   that   evidence,   as
    presented     by   individual    witnesses,    rather    than   described
    collectively, is stated in considerable detail as a backdrop to our
    consideration of Camacho’s CPC application.           The facts are also
    summarized in our court’s opinion affirming Camacho’s federal
    kidnaping conviction; on appeal from that conviction, Camacho
    raised some of the same claims he asserts now as the basis for
    federal habeas relief.     See United States v. Jackson, 
    978 F.2d 903
    (5th Cir. 1992), cert. denied, 
    509 U.S. 930
    (1993).
    Sam Junior Wright testified for the State as follows.         On 20
    May 1988, at approximately 8:00 a.m., he and his three-year-old
    - 5 -
    son, Andre Banks, were upstairs in his residence at 7927 Nassau
    Street, in the Pleasant Grove area of Dallas, Texas.   Wright lived
    there with Evellyn Banks (Andre’s mother) and her two sons, who had
    already left for school.      After hearing Evellyn Banks, who was
    downstairs at the time, cry out, Wright looked downstairs and saw
    a black man, whom he did not recognize, and another man, whom he
    recognized from prior drug-related dealings as “Gino”.     (At the
    time, Wright did not know “Gino’s” last name; Dallas Police and the
    FBI later identified him as the petitioner, Genaro Camacho.        The
    black man was later identified as Juan Jackson.)
    The black man ordered Wright and his son downstairs.         When
    Wright got there, he saw a white man (later identified as George
    David Cooke) whom he had never seen before.    Another “white guy”
    (later identified as Larry Gene Merrell, referred to in the record
    as an “Indian”), whom Wright also had never seen before, came in
    through the back door.   Gino did not have a weapon, but the other
    three intruders were armed.    Gino (Camacho) asserted that Wright
    owed him $20,000, and stated that, if Wright did not get the money,
    he would kill Evellyn and Andre Banks.    Gino then hit Wright.
    Upon hearing a knock at the door, Gino took a .357 Magnum from
    one of his accomplices and stood behind the door.    David Wilburn,
    Wright’s driver, entered the house.     Gino ordered Wilburn to lie
    face-down on the floor, and shortly thereafter shot him in the back
    of the head.   Gino told one of his accomplices to handcuff Evellyn
    Banks.
    - 6 -
    Wright escaped through the front door while the intruders were
    distracted by the sound of the back door slamming.                  He saw a
    neighbor, and shouted to her to call the police.           He eventually
    went to Evellyn’s mother’s home and told Evellyn’s brother what had
    occurred.     Evellyn’s brother went to Wright’s house and gave the
    name “Gino” to the police.    Wright later called the FBI and, after
    his subsequent arrest (for failing to appear for sentencing on a
    1985 drug conviction), gave a statement to the FBI.        At the time of
    trial,   Wright   was   serving   a   22-year   sentence   in   a    federal
    institution for the 1985 drug conviction and for failing to appear
    for sentencing. On cross-examination, Wright testified that he had
    moved for reduction of sentence, but that the motion had not yet
    been heard.
    One of Evellyn Banks’ sons, Cecil DeWayne Banks, identified
    Camacho in court and testified that he had seen Camacho at the
    Nassau residence on about four occasions prior to the day of the
    incident, 20 May 1988; and that Camacho never came alone, but
    usually was accompanied by at least two or three other men.
    Evellyn Banks’ brother, Darrell Anthony Banks, testified that he
    met Camacho at the Nassau house; and that on one occasion Camacho
    mentioned that Wright owed him money.
    Sabrina Wilson testified as follows.        In May 1988, she lived
    across the street from Wright’s house.      Around 8:30 a.m. on 20 May
    1988, when crossing the street after leaving a friend’s house, she
    saw a white car, and Wright shouted at her to call the police,
    because the people in the car had tried to kill him.            She saw a
    - 7 -
    driver and passenger, but did not know if anyone was in the back
    seat.    Wilson was six to eight feet from the driver’s side of the
    car, and got a close look at the driver, whom she identified in
    court as Camacho.
    After calling the police, Wilson went to work.               A detective
    showed   her   some   photographs   the     next   day   (21   May),   and   she
    identified Camacho’s photograph.            (Outside the presence of the
    jury, in an identification hearing, Wilson testified that she was
    shown the photographs “within a day or two” after the incident.)
    Retired Dallas Police Officer L. C. Lake testified that, while
    on patrol, he was called to Wright’s house; that he observed the
    burglar bars opened, the front door ajar, and a cut chain and
    padlock on the ground; and that, inside the front door, he saw a
    black male who appeared to be dead.
    Dallas Police Detective Michael W. Black testified that he
    responded to the call on Nassau on 20 May 1988; that a chain had
    been cut off the burglar bars on the front porch and pieces of the
    chain were on the ground; that the front door had been forced open,
    and pieces of the door frame were in the living room inside the
    front door; that Wilburn’s body was face-down in the living room
    just inside the front door; that the bullet entered the lower part
    of the back of Wilburn’s head and exited through his cheek; that
    bullet fragments were found on the rug just beneath Wilburn’s head,
    and a large bullet fragment was on the carpet three feet from
    Wilburn’s head; that it appeared to have been an execution-type
    killing; that drugs and drug paraphernalia were found in the house;
    - 8 -
    and that the fingerprints found at the scene were not identified as
    those of any of the individuals arrested.
    Following a competency hearing outside the presence of the
    jury, accomplice George David Cooke testified as follows.              Around
    6:00 a.m. on 20 May 1988, Camacho awakened him and said that he
    wanted Cooke to go with him “to collect some money”.                   Cooke,
    Jackson, and Merrell traveled to Wright’s house in a white Lincoln
    driven by Camacho.     Jackson, who was riding in the front passenger
    seat, took two semiautomatic pistols and a .357 Magnum from a bag
    under his feet and distributed them. When they arrived at Wright’s
    house, pursuant to Camacho’s orders, Jackson cut the lock on the
    burglar bars around the front porch; and Merrell went around the
    side of the house and cut the telephone lines.           Camacho kicked the
    front door open.       At some point, the .357 Magnum was handed to
    Cooke.    Jackson brought Sam Wright and Andre Banks downstairs, and
    Camacho asked Wright what happened to his money. Camacho mentioned
    that he had “left his boy” (referring to heroin) with Wright.
    Upon hearing a knock at the door, Camacho stepped behind the
    door and opened it; Jackson told the person at the door (Wilburn)
    to come in.      Camacho shut the door behind Wilburn, got the .357
    Magnum, ordered Wilburn to get on his knees, patted him down, and
    then ordered him to lie face-down on the floor.                Camacho told
    Jackson   to   shoot   Wilburn   if    Wilburn   moved   or   spoke.    After
    questioning Wright again about the money Wright owed him, Camacho
    walked over to Wilburn, put the gun to the back of his head, and
    shot him.      After further questioning of Wright about his money,
    - 9 -
    Camacho ordered Jackson to handcuff Evellyn Banks, and said that
    “we had to take them all with us”.        As they were leaving the house,
    Wright ran away.       Camacho, who was driving, ordered Jackson to get
    Wright, but Jackson said he could not catch him.               As they were
    driving away, they saw Wright running across a field and Camacho
    told Jackson to shoot him, but Jackson said he was too far away.
    Cooke testified that the captives were taken to a Dallas
    apartment he rented with Eddie Blaine Cummings.            After three days,
    Camacho, Cooke, Spencer Charles Stanley, and Evellyn and Andre
    Banks traveled to Oklahoma in Cooke’s car. Stanley had given Cooke
    a list of items that he wanted Cooke and Camacho to buy before the
    trip, including “tape, a knife, pillow, some lime ... and some
    rope”.     The group went to a motel in Ardmore, Oklahoma, arriving
    after midnight.        Stanley left to “dig a hole”.         Camacho assured
    Evellyn Banks that he had ordered an airplane to be flown to an
    airstrip, and that he would see that she and Andre Banks were flown
    “somewhere where she had some relatives”.
    Cooke testified further that, at approximately 10:00 p.m. that
    night, Camacho, Cooke, Stanley, and Evellyn and Andre Banks left
    the motel, ostensibly to go to the airstrip.              After driving to a
    remote   area,   the    group   walked   through   some    woods,   following
    Stanley, who was carrying Andre Banks on his back, to the grave
    Stanley had dug.    Stanley threw Andre Banks into the grave and shot
    him, and then shot Evellyn Banks.        Camacho ordered Stanley “to use
    the rest of the bullets” on Andre Banks, who was “still making some
    noises”.
    - 10 -
    After burying Andre and Evellyn Banks, Camacho, Stanley, and
    Cooke drove to Lake Texoma to dispose of the shovel, pickaxe, and
    weapon before returning to the motel in Ardmore.        They were joined
    there by Cummings and Pamela Miller; and then all of them returned
    to Dallas.
    Cooke testified that he had been arrested on 15 August 1988,
    and charged with two counts of aggravated kidnaping.              After his
    arrest, he led the FBI to the grave of Evellyn and Andre Banks.           At
    the time of the state trial, he had entered a guilty plea in
    federal court and was to be sentenced approximately a month later,
    in mid-May 1990.     He had also been indicted as an accomplice to
    murder and kidnaping in Dallas County, and intended to plead guilty
    to those charges.
    On cross-examination, Cooke testified that he and Cummings
    rented the car that was used to drive to Wright’s house on 20 May
    1988; that he purchased the semiautomatic weapons used at Wright’s
    house; and that he rented the motel room in Oklahoma.               He was
    initially charged with capital murder, but that charge was later
    reduced   to   murder.   Pursuant   to   his   plea   agreement    for   the
    aggravated kidnaping charge in federal court, his sentence was to
    be capped at 24 years, although the maximum punishment for that
    offense is life imprisonment.
    Another accomplice, Larry Gene Merrell, also testified for the
    State.    In most respects, Merrell’s testimony about the events at
    Wright’s house was consistent with Cooke’s.       However, according to
    Merrell, Cooke (rather than Jackson) distributed the weapons in the
    - 11 -
    car; Merrell (rather than Camacho) opened the door for Wilburn; and
    Merrell    (rather    than    Camacho)      was   standing   behind   the    door.
    Merrell’s testimony was also consistent, for the most part, with
    Wright’s testimony; however, Merrell testified that he entered
    Wright’s house through the front door (rather than the back, as
    Wright testified).       Merrell testified further that he saw Camacho
    shoot Wilburn in the back of the head; and that he went back to
    Oklahoma on the Sunday following the murder (22 May) and did not
    see Camacho or the kidnaped victims again.
    Merrell had been arrested on 16 September 1988, and made a
    statement to the FBI.             At the time of the state trial, he had
    pleaded guilty in federal court to one count of kidnaping and was
    awaiting sentencing; and he intended to plead guilty to a Dallas
    County kidnaping charge.           On cross-examination, Merrell testified
    that, pursuant to his plea bargain, he was subject to a maximum
    punishment of eight years.
    FBI    Special    Agent       Tase   Bailey      testified   regarding    the
    investigation and arrests of the suspects, as follows.                      On the
    evening of 21 May, FBI Agent Figueroa contacted him and advised
    that he had developed the name of a suspect.                 At that time, they
    knew only that the suspect was named “Gino” and that he had been
    arrested    previously       by   another    police    department.     The    next
    morning, 22 May, they determined that the suspect’s name was Genaro
    Camacho.    They obtained a photograph of Camacho, and Dallas Police
    conducted photographic line-ups. They were also trying to identify
    a white male, a black male, and possibly another Hispanic male.
    - 12 -
    Agent Bailey testified that Cooke led investigators to the grave of
    Evellyn and Andre Banks, and to the location where the weapon used
    to murder them had been thrown into Lake Texoma.
    On cross-examination, Agent Bailey testified that Cummings and
    Cooke were close associates; that Cummings selected the car used in
    the kidnaping and ordered Cooke to purchase the semiautomatic
    weapons; that Cooke stated that the handcuffs used on Evellyn Banks
    were obtained from Cummings; that Cummings offered jewelry, which
    he had stolen from his mother, to Cooke in exchange for the
    weapons; and that Merrell and Stanley were hometown friends of
    Cummings. On redirect examination, Agent Bailey testified that the
    reason Camacho, Cummings, and the others came together in Dallas
    was narcotics activity — Camacho was related to persons in Mexico,
    and   they   planned   to    fly     marijuana    into    the   Dallas    area    and
    distribute it from there; and that, when Camacho was arrested on 31
    March 1989, as he came across the bridge from Mexico into McAllen,
    Texas, he used the name “Tomas Sanchez”.
    The defense case consisted of further cross-examination of
    Wright, Agent Bailey, and Cooke.          When Cooke and Wright were asked
    to demonstrate how Camacho shot Wilburn, Cooke indicated that
    Camacho held the gun in his left hand; Wright, that Camacho used
    his right.
    The defense also presented the testimony of a Tarrant County
    probation officer and a psychologist.                    The probation officer
    testified that Wright had been placed on probation in 1981 for
    unlawful     possession     of   a   controlled    substance     (78     pounds   of
    - 13 -
    marijuana); that he had failed to report to the probation office at
    least 10 times; and that his probation had never been revoked.        The
    psychologist    testified   that,   after   conducting   a   series   of
    psychological tests on Cooke, at the request of Cooke’s attorney,
    he determined that Cooke was insane on 20 May 1988, and that
    Cooke’s “recollection of facts is ... very problematical ...
    [because] he has delusional disorder problems”. The defense theory
    was that Wright and Cooke were not credible witnesses, and that
    someone other than Camacho shot Wilburn.
    Cummings testified as a rebuttal witness for the State, as
    follows.      He met Camacho about two months prior to Wilburn’s
    murder, and he and Camacho discussed “making some big money” by
    flying marijuana into the United States from Mexico.         On 20 May
    1988, he and Pamela Miller were at the apartment when Evellyn and
    Andre Banks were brought there by Camacho, Cooke, Merrell, and
    Jackson.   Camacho told him that he (Camacho) had ordered Cooke to
    kill “the man”, but that Cooke could not follow orders, so he
    (Camacho) had to “kill the man”.      Although Camacho had discussed
    killing Merrell, it was agreed that Cummings would take Merrell
    back to Oklahoma and would try to locate an airplane to use in
    transporting Camacho to Mexico and then in transporting marijuana.
    Cummings had been arrested on 5 August 1988, and indicted in
    federal court as an accessory; had pleaded guilty; and was awaiting
    sentencing.
    FBI Special Agent Jose Figueroa also testified as a rebuttal
    witness for the State, as follows.       On 20 May 1988, he received a
    - 14 -
    call from the Dallas Police about the murder and kidnaping.                 He
    went to the neighborhood and spread the word that he needed to talk
    to Wright as soon as possible.        On 21 May, at approximately 10:00
    p.m., Wright called him and stated that the shooter was named
    “Gino”.   On 22 May, based on information provided by Wright in the
    21 May telephone conversation, he learned that “Gino” was Camacho.
    After Wright was arrested, Agent Figueroa interviewed him and
    showed him a photographic spread, from which Wright identified
    Camacho’s   photograph.        On   cross-examination,      Agent    Figueroa
    testified that there is no physical evidence that ties Camacho to
    Wright’s house or to the grave site in Oklahoma.
    Finally, Jeaneene Elizabeth Wallace testified as a rebuttal
    witness   for   the   State,   as    follows.      Her   friend,    Cummings,
    introduced her to Camacho.           In early May 1988, she was with
    Camacho, who was angry, and who “said that this man had owed him a
    lot of money, like $8,000.00, and then he grabbed me by the throat
    and he stuck his thumb in my throat and he said he was going to
    kill this man and his family because he grew good coca and he grew
    good marijuana and that this man owed him money”.
    A.
    Camacho    contends    that    the    prosecution   violated   Brady   by
    failing to disclose:       (1) the full extent of Cooke’s plea bargain
    agreement with the State; (2) that the State’s original theory
    involved three, rather than four, suspects, as reflected in the
    initial prosecution report prepared by Dallas Police Officer T. J.
    Barnes; (3) the affidavit of James Scott, who witnessed some of the
    - 15 -
    events surrounding the murder, and the fact that Scott identified
    someone other than Camacho from a photographic lineup; (4) that
    Jane Wallace did not identify Camacho from a photographic lineup as
    being at Wright’s house on 20 May 1988; and (5) that Rose Wallace
    was coerced by police to make a positive identification of Camacho
    when she was shown a photographic lineup.             (Camacho asserted a
    similar   Brady   claim   on   appeal    from   his    federal    kidnaping
    conviction.   See United States v. 
    Jackson, 978 F.2d at 912
    .) For
    these Brady claims, Camacho maintains that the district court also
    erred by denying his discovery and evidentiary hearing requests.
    As is well-known, “suppression by the prosecution of evidence
    favorable to an accused upon request violates due process where the
    evidence is material either to guilt or to punishment, irrespective
    of the good faith or bad faith of the prosecution”.              
    Brady, 373 U.S. at 87
    (emphasis added).    In United States v. Bagley, 
    473 U.S. 667
    (1985), a majority of the Court held that, regardless of
    whether requested by the accused, favorable evidence (exculpatory
    or impeachment) is material “if there is a reasonable probability
    that, had the evidence been disclosed to the defense, the result of
    the proceeding would have been different”. 
    Bagley, 473 U.S. at 682
    (opinion of Blackmun, J.); 
    id. at 685
    (White, J., concurring in
    part and concurring in judgment).       And, in Kyles v. Whitley, 
    514 U.S. 419
    (1995), the Court emphasized that Bagley materiality “is
    not a sufficiency of the evidence test”, 
    id. at 434;
    and that, in
    determining   materiality,     the   suppressed       evidence    must   be
    “considered collectively, not item-by-item”.            
    Id. at 436.
         We
    - 16 -
    review the Brady ruling de novo.                See East v. Johnson, 
    123 F.3d 235
    , 237 (5th Cir. 1997).
    1.
    Before      considering,      collectively,        the    materiality   of   the
    allegedly undisclosed items, Camacho’s contentions and the prior
    proceedings with respect to each of the items are summarized.
    a.
    Camacho contends that the State’s failure to disclose the
    extent of eyewitness Cooke’s plea bargain agreement with the State
    violated       his   rights    under    the    Fifth,    Sixth,    and   Fourteenth
    Amendments, because the full extent of the agreement was critical
    to a determination of Cooke’s credibility.                      Concomitantly, he
    asserts that the district court erred by denying his request to
    depose Cooke about Cooke’s understanding of the plea agreement, and
    by denying his request for an evidentiary hearing to resolve
    disputed factual issues which were not fully and fairly resolved in
    state court.
    At    a    pretrial      hearing   on     19   February    1990,    before   the
    commencement of testimony in Camacho’s capital murder trial, the
    attorney who represented Cooke in federal court testified that his
    understanding of the state plea bargain agreement was that it was
    for a life sentence; the attorney who represented Cooke on the
    state charges, that he had no knowledge regarding the agreement.
    As stated, Cooke testified at trial that his agreement with
    the State was that he would not be charged with capital murder and
    would receive a life sentence in exchange for his guilty plea to
    - 17 -
    kidnaping and murder.          And, at the close of the State’s case-in-
    chief, the prosecutor stated that Cooke had agreed to plead guilty
    to the Dallas County charges and that, in exchange for his plea,
    the State had agreed that, if Cooke testified truthfully, it would
    recommend a life sentence to be served concurrently with any
    sentence previously imposed in federal court.                    When Cooke was
    recalled by the defense, he testified that he was “exposed to two
    life sentences in the state”.
    Approximately a month after trial, in June 1990, Camacho moved
    for a new trial, alleging that, in return for his testimony, Cooke
    had received additional promises from the State that were not
    revealed to defense counsel and were not presented to the jury.                  At
    a hearing on the motion, Camacho introduced a 10 May 1990 letter
    (dated two days after Camacho was sentenced to death), from Hugh
    Lucas, lead counsel for the State at Camacho’s trial, to Dennis
    Brewer, Cooke’s       lawyer     on   the   federal   charges,    to    which   was
    attached a page outlining the State’s plea agreement with Cooke.
    The attachment stated that Cooke had not been indicted for capital
    murder; that    the     State    agreed     to   recommend   a   life    sentence,
    concurrent, on the Dallas County case; that, upon discharge of
    Cooke’s federal sentence, or the expiration of 20 calendar years,
    whichever is greater, the State would recommend parole and that
    Cooke   be   released     from     incarceration;      and   that,      after   the
    expiration of 30 calendar years, the State would recommend that
    Cooke be discharged from all Dallas County sentences.
    - 18 -
    Camacho’s   trial    counsel,    Joseph       Montemayor   and   Julius
    Whittier, testified that they did not learn of the entire agreement
    until after Camacho was sentenced to death.              On the other hand,
    Brewer (counsel on federal charges) testified that the attachment
    to   Lucas’   10   May   letter   reflected    his    understanding     of   the
    agreement between Cooke and the State; and that the agreement had
    been reached prior to Cooke’s testimony in Camacho’s trial.                  When
    asked by Camacho’s counsel if it was a “substantial benefit” for
    the State not to oppose parole eligibility, Brewer testified that
    “it’s a terrible detriment ... if the State does oppose it ...
    compared to the other alternative I guess it would be considered a
    benefit.”
    Lucas testified that he never agreed to recommend parole for
    Cooke; that the 10 May letter was prepared hurriedly, in response
    to a request by Brewer, who needed the letter in federal court that
    day,    and   mistakenly     included    the     terms    regarding     parole
    recommendation; that he was out of town when Cooke entered his
    guilty plea, and did not have an opportunity to correct the
    agreement; and that Cooke’s testimony at trial set out the plea
    agreement as he believed it to be at that time.
    Edwin King, Cooke’s attorney in state court, testified that
    the plea agreement was that Cooke was going to get a life sentence;
    and that he never saw Lucas’ 10 May letter until the day Cooke
    entered his guilty plea in state court.              King testified further
    that, in his opinion, the State’s recommendation regarding parole
    was not “worth the paper it’s written on”, but that “it made
    - 19 -
    Cook[e] feel better”; that he told Cooke that the agreement was
    that he was going to get life sentences, concurrent, and that, at
    a minimum, the State would not oppose his eligibility for parole;
    that both he and Brewer told Cooke that any parole decision would
    be made by the Board of Pardons and Paroles, not by the Dallas
    County District Attorney’s Office; and that the State’s agreement
    not to oppose parole eligibility “wasn’t so important that [Cooke]
    would have changed his mind”, because Cooke was more concerned
    about his federal sentence.
    Cooke, who was incarcerated in Oklahoma at the time, did not
    testify at the hearing on the new trial motion, because Camacho’s
    counsel was unable to secure his presence. (There is no indication
    in the record that Camacho’s counsel sought a continuance of the
    hearing in order to obtain Cooke’s testimony.)           At the conclusion
    of the hearing, the trial court denied the motion.
    The state habeas court concluded that Camacho was procedurally
    barred from raising the issue of whether the State failed to reveal
    the extent of Cooke’s plea agreement, because he did not raise the
    issue on direct appeal.       Alternatively, it found that Camacho
    failed to prove that an agreement existed outside the papers signed
    in Cooke’s case.
    The   district   court   held   that   disclosure    of   the   State’s
    agreement to recommend parole was not required, because those terms
    did not become part of the plea agreement until after Camacho’s
    trial ended; and that, although the State had agreed, prior to
    Cooke’s testimony, that it would not actively oppose parole for
    - 20 -
    Cooke at the end of his federal sentence, such agreement was not
    required to be disclosed because it was immaterial.              The court
    rejected Camacho’s request for an evidentiary hearing, stating that
    Cooke’s testimony was unnecessary, because “the record makes it
    clear that no Brady violation occurred”.
    b.
    The next claimed Brady violation is not disclosing the initial
    prosecution report of Dallas Police Officer T. J. Barnes, which
    reflects the State’s initial theory that the offense involved three
    perpetrators.      Camacho asserts that Barnes’ report, which states
    that Wright could testify that three men entered his house, could
    have been used to impeach Wright’s trial testimony that four
    entered.      And, again, he contends that the district court erred by
    denying his discovery and evidentiary hearing requests on this
    issue.
    The state habeas court rejected this claim, after making
    detailed findings; for example, that the State’s initial theory was
    readily available to the defense through medical reports, and
    because the substance of Barnes’ report was identical to the
    affidavit supporting the arrest warrant (a public record).
    The district court held that Wright’s trial testimony that
    three men were in his house when he was forced downstairs, and that
    a fourth entered later, was consistent with the statement in
    Barnes’ initial report that Wright could testify that Camacho and
    two other men broke into his house.           It concluded that, in the
    light    of   Cooke’s   and   Merrell’s   testimony,   which   corroborated
    - 21 -
    Wright’s testimony that four men entered and that Camacho shot
    Wilburn, the collateral nature of the alleged contradiction between
    Barnes’ report and Wright’s testimony compelled the conclusion that
    the undisclosed impeachment evidence was not material.
    c.
    The prosecution is claimed to have also violated Brady by
    failing to disclose the affidavit of James Scott, given to Dallas
    Police on the day of the incident, 20 May.    Camacho asserts that
    Scott’s testimony would have been favorable to him, because Scott
    saw only three men leave Wright’s house, and because Scott saw a
    black man driving the car away from Wright’s house, which would
    have contradicted Sabrina Wilson’s testimony that Camacho was
    driving.
    Scott’s 20 May affidavit states that he saw a Mexican man, a
    white man, and a black man at Wright’s house that morning; that he
    saw three men drag Evellyn Banks and her son to the car and put
    them in the back seat; that the white man and the Mexican man sat
    in the back seat with Evellyn and Andre Banks; and that “the
    colored man” drove.
    Scott did not testify at Camacho’s capital murder trial, but
    he testified for the defense in Camacho’s federal kidnaping trial.
    Consistent with his affidavit, he testified that he saw three men
    arrive at, and leave from, Wright’s house on 20 May 1988; and that
    the black man was driving the car as it left.     He described the
    Mexican man as having “sort of long” hair, “back on his neck”.
    - 22 -
    But, when asked at the federal trial whether there was any
    question in his mind about who was driving the car, Scott replied:
    “That’s what I thought.   I was scared because I didn’t want to get
    too close.”   And, when then asked whether he saw only three men
    get into the car, Scott stated: “That’s all I seen.    It may have
    been more, but that’s what I seen go to the car.”     When the car
    came back around the block, Scott did not know whether the black
    man was still driving.
    Scott testified further at the federal trial that a detective
    showed him some photographs of some “Spanish” individuals the next
    day, and he indicated to the detective the man he thought he had
    seen, but the detective told him he had picked the wrong one.   On
    cross-examination, Scott testified that he did not see the men
    drive up and did not see how many people got out of the car; and
    that Sabrina Wilson was in a position to see who was driving.
    In its response to Camacho’s state habeas application, the
    State submitted the affidavit of prosecutor Lucas, in which he
    stated that he interviewed Scott in April 1990, prior to Camacho’s
    state trial, and that Scott told him he was shown a photographic
    lineup and could not identify anyone.
    The state habeas court rejected this claim, with extensive
    findings; for example, that Scott’s identity as a potential witness
    was disclosed to the defense; that any inconsistency between
    Scott’s affidavit and the statements of other witnesses was not
    material, because Scott was equivocal in his identification of the
    driver of the getaway car, and his testimony did not exclude
    - 23 -
    Camacho from being present at, and responsible for, the murder;
    that Scott’s testimony that he was shown a photographic lineup was
    not credible; but that, even if he had been shown the lineup, the
    fact that he may have identified someone other than Camacho was not
    exculpatory, because Scott did not witness the murder and was not
    called as a witness.
    Likewise, the district court held that Scott’s affidavit was
    not inconsistent with the state trial testimony that three men
    entered the front door of Wright’s residence, while the fourth went
    around the side of the house to cut the telephone line.       It stated
    that, because three eyewitnesses testified that they saw Camacho
    shoot Wilburn, and because Scott testified at Camacho’s federal
    trial that, although he only saw three men come out of the house,
    there may have been more than three men involved, Scott’s affidavit
    was not material.
    The district court stated further that Scott’s statement
    regarding the driver was not material to whether Camacho murdered
    Wilburn.    It noted also that Scott testified at the federal
    kidnaping trial that he “thought” the black guy was driving, but
    was scared and did not want to get too close, and that Wilson’s
    testimony   that   Camacho   was   driving   was   corroborated   by   the
    testimony of Merrell and Cooke that Camacho drove the car to and
    from Wright’s house.
    The district court concluded that Camacho had failed to
    overcome the presumption that the state habeas court’s findings
    regarding whether Scott was shown a photo spread and did not
    - 24 -
    identify   Camacho     were    correct.          Finally,       it    held    that    the
    information in Scott’s affidavit could have been discovered through
    the exercise of reasonable diligence, because Scott’s name was
    provided to defense counsel in the State’s first witness list,
    filed 15 December 1989.
    d.
    The   fourth    Brady    claim    is    for    not   disclosing          that   Jane
    Wallace, who did not testify at Camacho’s capital murder trial, had
    failed to identify him as one of the perpetrators.                       Jane Wallace
    testified for the defense in Camacho’s federal trial that, on the
    morning of 20 May 1988, she saw a “Mexican” at Wright’s house, but
    could not see his face because his back was turned toward her; and
    that she thought she saw four to five men coming out of Wright’s
    house.
    She   testified    further       that   a     detective         showed   her    some
    photographs; that, when asked if she had ever seen any of the men
    in the photographs, she pointed out Camacho’s photograph, and
    signed the back of it, but she did not tell the detective where she
    had seen the man before, because he did not ask; and, that she
    recognized   Camacho’s       photograph      because      she    had    seen    him   at
    Wright’s residence on previous occasions, but she did not see him
    there on the morning of 20 May 1988.               She testified further that
    she did not remember seeing Camacho that morning, but that he could
    have been there.
    The state habeas court found that Jane Wallace’s testimony was
    not exculpatory, because she did not claim that Camacho was not
    - 25 -
    present at Wright’s house on the morning of the offense; and that
    her identity was disclosed to the defense prior to trial.
    The district court held that Brady does not require the
    disclosure of such evidence, because Jane Wallace did not tell the
    police when she had seen Camacho at the time she identified his
    photograph; accordingly, the State did not know that Jane Wallace
    identified   Camacho’s   photograph    because   she   had   seen   him   at
    Wright’s house on occasions prior to the murder, but that she did
    not see him there on the morning of the murder.
    Camacho contends that the district court’s conclusion is
    contradicted by Detective Barnes’ investigative notes, which state
    that “Jane Wallace ... identified Camacho and said she had seen him
    at Sam’s house numerous times before”.           He asserts that he is
    entitled to an evidentiary hearing to resolve the factual dispute
    regarding whether the police knew the basis for Jane Wallace’s
    identification of Camacho.
    e.
    The final Brady claim is for failing to disclose that Rose
    Wallace had been coerced into identifying Camacho’s photograph.
    Camacho asserts that her testimony would have been favorable to his
    defense, because it would have discredited the police investigation
    of the State’s theory of the case; alternatively, that reasonable
    jurists could disagree on whether her testimony would be favorable,
    and that the questions surrounding this evidence, including the
    display of the photographic spreads, are at least adequate to
    deserve encouragement to proceed further (obtain CPC).
    - 26 -
    Rose Wallace did not testify in Camacho’s capital murder
    trial, but she testified for him at his federal trial, as follows.
    On 20 May 1988, she saw Evellyn Banks in handcuffs sitting in the
    car by herself, but did not see Andre Banks; she saw two men
    outside Wright’s house; and she had seen “the Mexican guy” in the
    newspaper (as discussed below), but he had his back toward her.
    Later, a police officer showed her three photographs and asked her
    if she could identify anyone.   She told him that she could not,
    because the man had his back to her.    The officer told her she had
    to pick one, and showed her which photograph to pick.    Although she
    signed the back of Camacho’s photograph, she did not know if the
    man she saw at Wright’s house was Camacho; the photograph she
    signed was the same one that was in the newspaper.
    In response to Camacho’s state habeas application, the State
    submitted the affidavit of Detective Barnes, who stated that
    Camacho’s photograph did not appear in the newspaper until after
    Rose Wallace identified it.
    The state habeas court found that Rose Wallace’s allegations
    of coercion were not credible, and that Camacho had failed to prove
    that any coercion was exculpatory, because Rose Wallace was not
    called as a witness in his capital murder trial.
    The district court held that, because Rose Wallace did not
    testify   at   Camacho’s   capital     murder   trial,   her   forced
    identification was not favorable to his defense, because he could
    not use the evidence to impeach her.   The court stated further that
    her testimony would not have materially helped Camacho’s defense,
    - 27 -
    because she testified at the federal kidnaping trial that she could
    not identify the Hispanic male who was present at Wright’s house on
    the day of Wilburn’s murder, because his back was toward her.
    2.
    As   
    discussed supra
    ,   we     assume   that    the   presumption    of
    correctness does not apply to the state habeas court’s underlying
    factual findings on the Brady claims.           In addition, we assume that
    Camacho’s    claim    regarding       Cooke’s    plea   agreement     is    not
    procedurally   barred.      Nevertheless,       considering    the   allegedly
    undisclosed evidence collectively, we conclude that Camacho has not
    shown that there is a reasonable probability that, had the evidence
    been disclosed, the result of the proceeding would have been
    different.
    We agree with the district court that Camacho has not shown
    that the State suppressed an agreement to recommend parole or
    discharge    for   Cooke,   because    the   evidence    reflects    that   the
    agreement did not exist until after Camacho’s capital murder trial,
    when the prosecutor mistakenly included those terms in a hurriedly-
    drafted letter for Cooke’s federal counsel.              Although the State
    did not disclose to Camacho’s counsel that it had verbally agreed
    to not oppose Cooke’s parole, there is no basis for inferring that
    such an agreement influenced Cooke’s testimony, in the light of the
    evidence that Cooke was well aware that the Dallas County District
    Attorney’s Office had no influence over parole decisions made by
    the Texas Board of Pardons and Paroles.          (His counsel on the State
    - 28 -
    charges testified that he and the attorney representing Cooke in
    federal court so informed Cooke, as 
    noted supra
    ).
    Cooke’s     eyewitness   testimony      about   Wilburn’s      murder   was
    corroborated by the eyewitness testimony of Wright and Merrell. It
    was further corroborated by Wilson’s testimony that Camacho drove
    the car away from the scene of the murder, and by the testimony of
    Cummings,   to    whom    Camacho    admitted    committing        the   murder.
    Considering the jury’s knowledge that Cooke had avoided a capital
    murder   charge    by    pleading   guilty,     there   is    no     reasonable
    probability that its determination of his credibility would have
    been affected by knowledge of whatever marginal benefit Cooke might
    receive from the State’s agreement not to oppose his parole.                 See
    Pyles v. Johnson, ___ F.3d ___, ___, 
    1998 WL 94881
    , at *13 (5th
    Cir. 1998) (where State’s witness admitted that self-interest
    motivated his testimony, disclosure of the terms of a better deal
    than described by the witness at trial “would have at best had a
    marginal negative impact on the jury’s credibility assessment”).
    The State asserts that Camacho has not demonstrated that the
    evidence regarding James Scott and Jane and Rose Wallace was
    suppressed, because each of their names appeared on the State’s
    first witness list, filed three months before trial, and the
    defense, exercising reasonable diligence, could have interviewed
    each of them and discovered what each knew about the events of 20
    May 1988.   Although the State is correct that “[a] Brady violation
    does not arise if the defendant, using reasonable diligence, could
    have obtained the information”, Williams v. Scott, 
    35 F.3d 159
    , 163
    - 29 -
    (5th Cir. 1994), cert. denied, 
    513 U.S. 1137
    (1995), we will make
    yet another assumption beneficial to Camacho:        that the disclosure
    of the identities of these witnesses was not adequate to apprise
    the   defense   of   their   knowledge   of    the    relevant   events.
    Nevertheless, we conclude that the suppressed evidence, to the
    extent that it was exculpatory, was not material.
    None of the three claimed to have witnessed the murder, and
    their testimony was not consistent.           Even assuming that Rose
    Wallace was coerced into identifying Camacho, her testimony would
    not have impeached that of the eyewitnesses to the murder.          The
    statement in the investigative notes that Jane Wallace stated that
    she had seen Camacho at Wright’s house numerous times before does
    not support an inference that she told the police officer that she
    did not see Camacho at Wright’s house on the day of the murder.
    Moreover, neither Rose nor Jane Wallace could say that Camacho was
    not present at Wright’s house on the morning of 20 May, because
    both stated that the “Mexican” man had his back to them.
    Scott’s statement that he saw three men enter the house and
    three men drive away from the house is not inconsistent with the
    trial testimony that three men (Camacho, Cooke, and Jackson)
    entered the front of the house, while the fourth (Merrell) went
    around to the back of the house to cut the telephone line, and
    entered the house later.      The fact that Scott did not see the
    fourth man is understandable, because he did not see the men get
    out of the car and did not look outside until he heard the noise
    made by the three men who were breaking in at the front door.
    - 30 -
    Likewise, Scott’s statement that he saw three men leave was not
    necessarily inconsistent with the trial testimony that Camacho sent
    Jackson to look for Wright, who had escaped.       Moreover, at the
    federal kidnaping trial, Scott was equivocal about whether three
    men or more got into the car after coming out of Wright’s house; as
    noted, he stated: “That’s all I seen.     It may have been more, but
    that’s what I seen go to the car.”
    Scott’s statement that he thought that a black man was driving
    as the car departed, but was unsure who was driving when the car
    came back around the block, is insignificant and does not exculpate
    Camacho from responsibility for the murder, because, as noted,
    Scott admitted that he was scared to get too close, and that
    Wilson, who positively identified Camacho as the driver, was in a
    better position to do so.
    Contrary to Camacho’s assertion, Wilson was not the only
    disinterested witness who placed Camacho at the scene of the
    murder.   Wright also placed him there.   Camacho has not shown that
    Wright had a motive to identify Camacho, rather than one of the
    others, as the shooter.
    Scott’s alleged “misidentification” also is not exculpatory,
    because Scott could not identify any of the perpetrators. Although
    Scott apparently told a police officer during the investigation
    that the “Mexican” had “shoulder length” hair, he testified at the
    federal trial that it was “[n]ot real long” and was “back on his
    neck”.    In the light of the fact that the photographs of Camacho
    indicate that his own hair was fairly long, he has not demonstrated
    - 31 -
    that Scott’s description fit any other possible suspect more than
    it fit him.
    Even assuming that Scott was shown a photographic lineup,
    Scott’s federal trial testimony that a detective told him that he
    had picked the wrong photograph out of a lineup does not undermine
    our confidence in the verdict.      Scott did not claim to have
    witnessed the murder, and three of the eyewitnesses to it testified
    that Camacho shot Wilburn.    Their testimony was corroborated by
    Wilson’s identification of Camacho as the driver of the car and by
    Cummings’ testimony that Camacho admitted to him that he committed
    the murder.
    The fact that the State’s initial theory was that three men
    committed the offense was a matter of public record and was
    available to Camacho and his counsel.   But, even assuming that the
    State had a duty to disclose it, this is neither material nor
    exculpatory. That Detective Barnes’ initial report indicates three
    suspects were involved does not tend to demonstrate that Camacho
    was not one of them.   Nor, again, does it undermine the testimony
    of three eyewitnesses that Camacho shot Wilburn.
    Camacho asserts that he was entitled to discovery and an
    evidentiary hearing, because there is a factual dispute regarding
    when the FBI and Dallas Police learned of Camacho’s identity and
    obtained a photograph of him. This contention is based on Wilson’s
    trial testimony that she was shown a photographic lineup “the day
    after” (21 May) the offense occurred, which purportedly contradicts
    other evidence that the FBI and Dallas Police did not learn
    - 32 -
    Camacho’s   identity   until   22   May,   after   Wright’s   telephone
    conversation with FBI Agent Figueroa on the evening of 21 May.
    Camacho asserts that the inconsistency raises the “all important
    question” of how the FBI or Dallas Police Department learned of
    Camacho’s identity prior to his being identified by Wright.
    The alleged discrepancy was apparent at Camacho’s state trial,
    and could have been explored then.         In any event, the record
    demonstrates that, in Wilson’s state court testimony, she was
    mistaken about the lineup date.     As stated, in the identification
    hearing outside the presence of the jury immediately prior to her
    trial testimony, Wilson stated that she was shown the lineup a day
    or two after the incident.     At the federal trial, Wilson testified
    that she gave a description of the suspects to FBI agents on 21
    May, but was not shown any photographs at that time, and then, on
    22 May, Detective Barnes showed her a photographic lineup.          Her
    testimony is corroborated by Agent Figueroa’s testimony at the
    federal trial that he first obtained a photograph of Camacho on 22
    May and gave that photograph to Detective Barnes for use in a
    photographic lineup to be shown that day to Wilson.
    In sum, the net effect of evidence that the State’s initial
    theory involved three suspects rather than four; that a witness who
    did not testify at trial saw only three suspects and thought the
    driver of the getaway car was black rather than Hispanic; that
    witnesses who did not testify at trial were unable to identify
    Camacho as being at Wright’s house on 20 May; that another witness
    who did not testify at trial was coerced into identifying Camacho’s
    - 33 -
    photograph; that one witness was mistaken as to when she was shown
    a photographic lineup; and that the State had agreed not to oppose
    parole for one of the accomplice eyewitnesses, is not sufficient to
    undermine our confidence in the verdict.         Therefore, we conclude
    that there is no reasonable probability that, had such evidence
    been disclosed, the outcome of Camacho’s trial would have been
    different.
    Concomitantly,    because   Camacho   has   not   demonstrated   the
    existence of a factual dispute that, if resolved in his favor,
    would entitle him to relief, the district court did not err by
    denying his requests to employ an expert, and for discovery and an
    evidentiary hearing.   See Perillo v. Johnson, 
    79 F.3d 441
    , 444 (5th
    Cir. 1996) (a federal habeas petitioner is entitled to discovery
    and an evidentiary hearing only “[w]hen there is a factual dispute
    [that], if resolved in the petitioner’s favor, would entitle [him]
    to relief and the state has not afforded the petitioner a full and
    fair evidentiary hearing”); see also Harris v. Johnson, 
    81 F.3d 535
    , 540 (5th Cir.), cert. denied, ___ U.S. ___, 
    116 S. Ct. 1863
    (1996).
    B.
    Camacho contends that he is entitled to a new trial because of
    newly-discovered evidence pointing to his innocence, and that
    executing him without a jury’s consideration of such evidence would
    deprive him of his life without due process.        Along this line, he
    contends that he is entitled to discovery, funds with which to
    employ an expert witness, and an evidentiary hearing.
    - 34 -
    “[I]t has long been a habeas rule that ‘the existence merely
    of newly discovered evidence relevant to the guilt of a state
    prisoner is not a ground for relief on federal habeas corpus.’”
    Lucas v. 
    Johnson, 132 F.3d at 1074
    (quoting Herrera v. Collins, 
    954 F.2d 1029
    , 1034 (5th Cir. 1992), aff’d, 
    506 U.S. 390
    (1993)).     “[A]
    claim of ‘actual innocence’ is not itself a constitutional claim,
    but instead a gateway through which a habeas petitioner must pass
    to have his otherwise barred constitutional claim considered on the
    merits.”   
    Herrera, 506 U.S. at 404
    .     Camacho appears to rely on the
    Supreme Court’s assumption, arguendo, that “a truly persuasive
    demonstration of ‘actual innocence’ made after trial would render
    the execution of a defendant unconstitutional, and warrant federal
    habeas relief if there were no state avenue open to process such a
    claim”.    
    Id. at 417.
      The Court noted that “the threshold showing
    for such an assumed right would necessarily be extraordinarily
    high”.    
    Id. Camacho’s claim
    is based on the 14 August 1992 affidavit of
    Bobby Newton (dated more than four years after the murder), which
    was attached to Camacho’s state habeas application.      The affidavit
    states that, early in the morning on 19 May 1988 (the day before
    the murder), Newton was sitting on the front porch of a friend,
    Danny Sheffield, directly across the street from Wright’s house;
    that three men arrived in a big, light-colored car and knocked on
    the door of Wright’s house; that Wilburn opened the door; that one
    of the men shot Wilburn in the back of the head, causing Wilburn to
    - 35 -
    fall to the floor, face-first; and that he knew Camacho, but did
    not see him at Wright’s house on the morning Wilburn was murdered.
    In response to Camacho’s state habeas application, the State
    submitted the affidavit of Detective Barnes, who stated that the
    events described in Newton’s affidavit did not match the physical
    evidence;    and   the   affidavits   of   long-time   residents   of   the
    neighborhood, who stated that they did not know either Newton or
    Sheffield.
    The state habeas court rejected this claim, and made extensive
    factual findings; for example, that Newton was not credible,
    because he did not assert that he was present on the date the
    offense occurred, and because the events described by Newton were
    contrary to the physical and eyewitness evidence.
    The district court held that it was unnecessary to consider
    whether the state court’s findings were supported by the record,
    because Newton subsequently recanted the contents of his affidavit.
    In a 27 May 1996 letter to Camacho’s counsel, Newton stated:
    Mr. Murphy I am writing you back to let you
    know that I don’t wish to testify for you or
    the State because when I gave you this so-
    called affidavit 4 years ago it was because at
    that time I need a lawyer to help stop me from
    coming to T.D.C. Mr. Murphy I am very sorry
    about this man but I can’t an will not help
    him because I wasn’t there.     I lie so you
    would help me an I was willing to lie for him
    but since I have done my time here in T.D.C.
    without your help why would you have the nuts
    to send me these papers. I tell you this one
    thing if you are the State have me come to
    court I will tell those people I didn’t see
    nothings also my mother and father didn’t see
    anything so they better not come up hurt in
    any way.... But I will not lie for him or you
    so Mr. Murphy please let me do my time an go
    - 36 -
    home to my family.... I will not testify for
    him or against him.    I didn’t see or hear
    anything. I was running from the Law myself
    when I seen you I seen my way out of here but
    you didn’t help me so I will not lie for you
    that life so don’t write or send me anything
    because I will tell the State the truth. You
    have a nice day tell Mr. Camacho to pray but
    if he killed Evellyn Bank an the baby boy he
    should an will pay. But I will not have their
    blood on my hand. NO!! WAY.
    Concerning his assertion that the district court erred by
    refusing to allow discovery on Newton’s recantation and to conduct
    an   evidentiary   hearing,   Camacho     maintains     that   discovery   was
    necessary to determine whether counsel’s suspicions about post-
    affidavit contacts by law enforcement agencies with Newton were
    responsible for his recantation.          And, he contends that he was
    entitled to depose the physician who performed the autopsy of
    Wilburn, to determine whether Wilburn was shot as Newton stated in
    his affidavit.
    Camacho also maintains that the district court erred by
    denying his motion for authorization to employ an independent
    private pathologist.     In that motion, Camacho asserted that his
    counsel   had   informally    consulted    with   Dr.    Charles   Petty,    a
    pathologist and former Chief Medical Examiner for Dallas County,
    who testified at trial; that Dr. Petty reviewed the autopsy report
    and his trial testimony along with photographs of the crime scene;
    and that Dr. Petty was of the preliminary opinion that, although he
    testified at trial that the cause of death was consistent with an
    individual who had been forced to lie on the floor and had a weapon
    placed either at or near his body and the trigger pulled, the
    - 37 -
    physical evidence      of   the   autopsy   and   crime   scene   is   equally
    consistent with the version of events related in Newton’s affidavit
    — that Wilburn was shot standing up just inside the doorway.
    Camacho contends further that he is entitled to a CPC on this
    claim because someone other than Newton gave a similar account to
    the police and the news media on the day of the murder.                      In
    support, Camacho relies on a 20 May 1988 newspaper article, in
    which it is reported that a Dallas Police Officer said that
    “[w]hile the assailants were in the house, a visitor knocked on the
    door and was shot to death as he stood in the doorway”, and that an
    unidentified witness said that, after Wilburn knocked on the door,
    “[s]omebody said come in and then they shot him right at the door”.
    Even assuming that a claim has been stated for federal habeas
    relief based on actual innocence, it fails for a number of reasons.
    First, as the district court noted, Newton recanted.              Second, his
    affidavit falls far short of “a truly persuasive demonstration of
    ‘actual innocence’”.        See 
    Herrera, 506 U.S. at 417
    .               In his
    affidavit, Newton claims to have observed the murder the day before
    it   occurred.   The    record    contains   evidence     that    he   had   one
    misdemeanor and five felony convictions; and that Sheffield, the
    friend Newton claims to have been visiting on the day of the
    murder, did not live in either of the houses located directly
    across from Wright’s.        Newton’s statement that the victim was
    already at Wright’s house when the perpetrators arrived, and opened
    the door for them, is contradicted by testimony that entry into the
    house was forced and by crime scene photographs showing that a part
    - 38 -
    of the door frame was broken when entry into the house was forced,
    as well as by the newspaper article Camacho relies on, which states
    that the unnamed witness stated that the victim drove up after the
    suspects arrived and was killed after they opened the door for him.
    Finally, the affidavit is contradicted by the eyewitness testimony
    of three individuals inside the room when Wilburn was shot.
    Camacho’s     conclusory         assertion   that   unidentified      law
    enforcement officers might have influenced Newton’s recantation is
    speculative and insufficient to demonstrate the existence of a
    factual dispute that, if resolved in his favor, would entitle him
    to relief.      Accordingly, for this claim, he was not entitled to
    expert assistance, discovery, or an evidentiary hearing.
    C.
    Relying on Batson v. Kentucky, 
    476 U.S. 79
    (1986), Camacho
    contends that the prosecutor’s exercise of peremptory challenges to
    exclude three minority venire members (Elizabeth Gamboa, who is
    Hispanic; Johnny Crowder and Charles Brooks, both of whom are
    black)   from    the    jury   were    racially   motivated   and   that   the
    prosecutor’s reasons for striking them were pretextual.
    To establish a Batson violation, Camacho must prove, of
    course, that the strikes were motivated by purposeful racial
    discrimination.        
    Batson, 476 U.S. at 94
    n.18; see also Purkett v.
    Elem, 
    514 U.S. 765
    , 767-68 (1995). In a federal habeas proceeding,
    the trial court’s rulings on discrimination and pretext are factual
    findings that are presumptively correct.           See 
    Purkett, 514 U.S. at 769
    (quoting pre-AEDPA 28 U.S.C. § 2254(d)); Washington v. Johnson,
    - 39 -
    
    90 F.3d 945
    , 954 (5th Cir. 1996), cert. denied, ___ U.S. ___, 
    117 S. Ct. 1259
    (1997).       Inasmuch as the factual findings on the Batson
    claims were made by the trial court after a live evidentiary
    hearing,    we   do    not    understand       Camacho    to    contend    that    the
    presumption is inapplicable to these claims.
    At the conclusion of voir dire, but before the jurors were
    sworn, the trial court conducted a hearing on Camacho’s charge that
    the State’s peremptory challenges were racially motivated; the
    prosecutor gave the following reasons for them.
    As for Elizabeth Gamboa, he noted her youth (she was 24); she
    still   lived    at    home   with    her    parents;    her    apparent    lack    of
    understanding of some of the terms used in the indictment; and his
    belief that she was “just not assertive enough to make a critical
    decision on someone’s life”.
    Crowder     was    struck       because    he     indicated     on   his   juror
    questionnaire that he did not believe in the death penalty, but
    testified during voir dire that, under certain circumstances, he
    did believe in it.       The prosecutor testified that he tried to make
    sure that no one was selected as a juror who had circled the
    following    statement,       as     had    Crowder,     on    his   questionnaire:
    “Although I do not personally believe in the death penalty, as long
    as the law provides for it I could assess it under the proper set
    of facts and circumstances.”
    Finally, with respect to Brooks, his questionnaire appeared to
    be contradictory as to whether he believed in the death penalty;
    and, during voir dire, Brooks “could not adequately explain what to
    - 40 -
    me was a discrepancy [—] he didn’t believe in the death penalty in
    one question.     The next question was, he did believe in it, and he
    just ... he cannot adequately explain that answer.” The prosecutor
    also had some concern that Brooks was answering the questions in a
    such a way as to ensure that he was selected as a juror, because
    the bailiff had told him that someone who would be questioned that
    day had expressed an interest in serving on the jury and had asked
    how to respond to the questions in a way that would ensure
    selection.
    Following the hearing, the trial court made extensive findings
    of fact, including that the State gave no explanations based on
    group bias; that it had articulated nondiscriminatory reasons for
    the use of its peremptory challenges; and that there was no
    purposeful discrimination by it in the exercise of its peremptory
    challenges.
    These findings are fully supported by the record.                      See 28
    U.S.C.    §    2254(d)   (pre-AEDPA);       
    Purkett, 514 U.S. at 769
    .
    Accordingly, Camacho is not entitled to a CPC on his Batson claims.
    D.
    Camacho’s final claim is that the admission of evidence of the
    murders   of   Evellyn   and   Andre    Banks   deprived     him   of   a    Sixth
    Amendment “right to a fair trial”.          At trial and on direct appeal,
    Camacho objected to this evidence on general relevance grounds.
    And, he did not present this claim in his state habeas application.
    However, he asserts constitutional grounds for the first time in
    his federal habeas petition.
    - 41 -
    The State contends that federal habeas review is barred by
    Camacho’s failure to raise this claim in state court, because, if
    Camacho attempted to raise it in a new state habeas application,
    the Texas Court of Criminal Appeals would find an abuse of the
    writ.     See Nobles v. Johnson, 
    127 F.3d 409
    , 423 (5th Cir. 1997).
    It contends further that state review would be barred by the
    absence of a contemporaneous objection on Sixth Amendment grounds.
    Alternatively, it contends that Camacho has not established that
    the admission of this evidence violated the Constitution.
    It goes without saying that, in reviewing state evidentiary
    rulings, the role of federal courts “is limited to determining
    whether a trial judge’s error is so extreme that it constituted
    denial of fundamental fairness.”    Woods v. Johnson, 
    75 F.3d 1017
    ,
    1038 (5th Cir.), cert. denied, ___ U.S. ___, 
    117 S. Ct. 150
    (1996).
    “The test applied to determine whether a trial error makes a trial
    fundamentally unfair is whether there is a reasonable probability
    that the verdict might have been different had the trial been
    properly conducted.”    Kirkpatrick v. Blackburn, 
    777 F.2d 272
    , 278-
    79 (5th Cir. 1985), cert. denied, 
    476 U.S. 1178
    (1986).     “Habeas
    relief is warranted only when the erroneous admission of evidence
    played a crucial, critical and highly significant role in the
    trial.”     Lucas v. 
    Johnson, 132 F.3d at 1082
    (internal quotation
    marks, brackets, and citation omitted).
    When considering challenges to the admission of extraneous
    offenses under the Due Process Clause of the Fourteenth Amendment,
    which guarantees “fundamental fairness” (as noted, Camacho’s claim
    - 42 -
    is based on his asserted Sixth Amendment “right to a fair trial”),
    our court has considered two factors: whether there is a strong
    showing that the appellant committed the offense; and whether the
    extraneous   offense   is     rationally    connected      with    the    offense
    charged.   See Pentecost v. Estelle, 
    582 F.2d 1029
    , 1031 (5th Cir.
    1978); Hills v. Henderson, 
    529 F.2d 397
    , 400 (5th Cir.), cert.
    denied, 
    429 U.S. 850
    (1976).
    Assuming   that   federal    habeas     review   is    not    procedurally
    barred, Camacho has not shown that the evidence was admitted
    erroneously. First, there was a strong showing, through eyewitness
    testimony, as to Camacho’s involvement in the kidnaping and murder
    of Evellyn and Andre Banks.         And, those murders are rationally
    connected with Wilburn’s; the murders of Evellyn and Andre Banks
    eliminated two of the eyewitnesses to Camacho’s murder of Wilburn.
    But, even assuming that the evidence was admitted erroneously,
    Camacho still has not shown that it had a substantial impact on the
    verdict or rendered his trial fundamentally unfair.                  As Camacho
    conceded in his brief filed in the Texas Court of Criminal Appeals
    on direct appeal, the evidence of his guilt was “overwhelming”, and
    the State’s case was “powerful and unimpeached”. This is true even
    without considering the evidence of the murders of Evellyn and
    Andre Banks.    Again, three eyewitnesses — Wright, Cooke, and
    Merrell — testified that Camacho shot Wilburn.                    Again, Wilson
    testified that she saw Camacho leaving the scene.                   And, again,
    Cummings testified     that    Camacho     admitted   to   him     that   he   had
    committed the murder.       In sum, as the district court stated, the
    - 43 -
    evidence   of   Camacho’s   guilt   for   Wilburn’s   murder   was   so
    overwhelming that there is no reasonable probability that the jury
    would have acquitted Camacho had the evidence of the murders of
    Evellyn and Andre Banks been excluded.       Accordingly, this issue
    also does not provide a basis for a CPC.
    III.
    Because Camacho fails to establish a basis for a certificate
    of probable cause, his request for the certificate is DENIED and
    the stay of execution is VACATED.
