    Before ROSENBAUM, GRANT and HULL, Circuit Judges.
    HULL, Circuit Judge:
    Case: 18-10145     Date Filed: 10/07/2019   Page: 2 of 52
    Dieter Riechmann, a Florida state prisoner, appeals the district court’s denial
    of his 28 U.S.C. § 2254 federal habeas corpus petition challenging his convictions
    for first-degree murder and possession of a firearm during the commission of a
    felony. This Court granted a certificate of appealability (“COA”) on two issues:
    (1) whether trial counsel provided ineffective assistance by failing to investigate
    and present available evidence that Riechmann’s relationship with the victim was
    loving and respectful and that he did not “live off” her; and (2) whether the state’s
    failure to disclose to the defense the statements of Swiss and German witnesses
    interviewed by German police violated Brady v. Maryland, 
    373 U.S. 83
    , 
    83 S. Ct. 1194
    (1963). After review, and with the benefit of oral argument, we affirm.
    I. STATE TRIAL PROCEEDINGS
    In 1987, a grand jury indicted Riechmann on charges of premeditated
    first-degree murder of Kersten Kischnick and use of a firearm during the
    commission of the murder. Riechmann and Kischnick, “life companions” of 13
    years, were German citizens and residents who came to Florida on October 2,
    1987, for a vacation. On October 25, 1987, Kischnick was shot to death in Miami
    Beach while she sat in the passenger seat of the couple’s rental car.
    At trial, the state’s theory of the case was that the victim, Kischnick, was a
    prostitute who financially supported Riechmann, who was her pimp. When
    Kischnick decided to quit prostitution, Riechmann killed her to recover valuable
    2
    Case: 18-10145     Date Filed: 10/07/2019    Page: 3 of 52
    life insurance proceeds. As to the specific facts of the murder, the state sought to
    prove that Riechmann stood outside the passenger side of the rental car and fired a
    single shot through the partially open passenger-side window, striking Kischnick in
    the head and killing her. Riechmann insisted to police and at trial that a random
    stranger shot Kischnick when they stopped the car to ask for directions. He
    consistently denied committing the crime.
    A. Pretrial Proceedings
    Prior to trial, Riechmann’s defense counsel learned that the state was in
    possession of 37 statements taken by the German police in connection with its
    parallel investigation of Riechmann. It appears from the record that defense
    counsel was in possession of the list of names but not all of the statements
    themselves. These were statements of persons in Germany and Switzerland who
    knew Riechmann and Kischnick.
    Riechmann’s defense counsel did have the statements of ten of those 37
    witnesses—the statements of those who might testify at trial—and he requested
    copies of the 27 remaining statements. The state failed to provide the defense with
    these 27 other statements despite the state trial court’s on-the-record ruling that
    Riechmann was to get “carte blanche discovery . . . . No ifs, ands, or buts. No
    conditions. Whatever the state has he gets.”
    3
    Case: 18-10145     Date Filed: 10/07/2019   Page: 4 of 52
    When the prosecutor refused to comply, Riechmann’s defense counsel
    moved the state trial court to conduct an in camera inspection of the statements and
    turn the relevant statements over to the defense. It does not appear that the state
    trial court ever ruled on that motion, and Riechmann’s trial counsel did not renew
    it.
    Despite learning about the existence of several Swiss and German persons
    who might have had relevant information about the nature of Riechmann and
    Kischnick’s relationship, defense counsel spoke to no German witnesses prior to
    trial, nor did he send an investigator to Germany. Riechmann also provided his
    defense counsel with a handwritten list of persons in Germany to depose or
    contact, but defense counsel did not contact anyone on the list.
    B. Riechmann and Kischnick’s Relationship
    At trial, the government sought to establish the nature of Riechmann and
    Kischnick’s relationship primarily through the testimony of four German
    witnesses, including Kischnick’s sister. These witnesses were culled from the list
    of 37 German witnesses referenced above.
    The first of these witnesses was Peter Carsten Meyer-Reinach, who met
    Riechmann and Kischnick in Hamburg in 1977. During the time of his
    acquaintance with the couple, Meyer-Reinach knew Kischnick to be a prostitute
    4
    Case: 18-10145        Date Filed: 10/07/2019       Page: 5 of 52
    and Riechmann to be her pimp. During that time, Kischnick earned between 1,000
    and 1,500 German marks per day as a prostitute.1
    At some point, Riechmann and Kischnick moved from Hamburg to a
    German town near the Swiss border, in part because “the work for
    [Kischnick] . . . wasn’t good anymore.” Meyer-Reinach saw Riechmann twice
    more following the move, and during one of these interactions, Riechmann
    commented that Kischnick “really didn’t feel like working anymore.”
    The second German witness, Ernst Siegfried Steffen, was an insurance agent
    in Hamburg who sold various life insurance policies to Riechmann and Kischnick.
    Steffen too had met Riechmann in Hamburg in 1977, and was aware that
    Kischnick worked as a prostitute under the name Yvonne. Riechmann had also
    told Steffen that Riechmann worked as a pimp.
    Steffen confirmed Riechmann and Kischnick maintained a “high standard of
    living” while in Hamburg, and he believed Kischnick was making about 1,000
    German marks per day as a prostitute. As for Riechmann, Steffen recalled helping
    him obtain a luxury apartment by verifying a certificate of earnings showing
    Riechmann made 3,950 German marks per month, though the certificate of
    earnings did not state the origin of those earnings. Riechmann also told Steffen
    that he had received training as an insurance agent. Like Meyer-Reinach, Steffen
    1
    Prostitution is, and was at the time of the murder, legal in Germany.
    5
    Case: 18-10145     Date Filed: 10/07/2019   Page: 6 of 52
    was aware that Riechmann and Kischnick had at some point moved to southern
    Germany near the Swiss border, in part because “[b]usiness apparently wasn’t
    going too well in Hamburg.”
    The third witness was Kischnick’s younger sister, Regina, who first met
    Riechmann when Kischnick brought him home in 1974. Regina did not learn of
    her sister’s occupation until several years later. During the time that Riechmann
    and Kischnick lived in Hamburg, Regina never knew Riechmann to work at any
    particular job, though she recalled Kischnick telling her that Riechmann “had
    business dealings with Arabs”—specifically, “dealings in gold.” Kischnick
    seemed content, if not happy, in her life with Riechmann in Hamburg, but she
    became noticeably unhappy upon their move to southern Germany. On the
    occasions that Regina visited her sister in southern Germany, it did not appear to
    her that Riechmann was working. Regina learned that Kischnick had gotten
    married to someone other than Riechmann and obtained a Swiss passport. There
    were several times when Regina would call the apartment in southern Germany
    and Riechmann would answer and tell her that Kischnick “was in Switzerland with
    a girlfriend.” Regina often heard Riechmann make derogatory comments about
    Kischnick’s age and figure.
    On cross-examination, Regina stated that she believed much of the
    expensive jewelry and apartment furnishings Riechmann and Kischnick owned had
    6
    Case: 18-10145     Date Filed: 10/07/2019   Page: 7 of 52
    been paid for by Kischnick’s earnings. Regina conceded, however, that the
    couple’s earnings likely were supplemented in some way by Riechmann, and that
    she had no way of definitively knowing the origin of the money used to purchase
    particular gifts or furnishings.
    The final witness was a woman named Dina Mohler, who then worked as a
    prostitute in Switzerland. Mohler first met Kischnick a few years after Kischnick
    and Riechmann moved to southern Germany. Kischnick had replied to an
    advertisement Mohler placed in the newspaper seeking a “colleague” with whom
    to share her apartment. By “colleague,” Mohler meant another prostitute who
    would pay rent to use the shared space. Kischnick, who worked under the name
    Yvonne, was supposed to pay Mohler 1,000 Swiss francs per month to use the
    apartment, but Kischnick was unable to make this payment because she was
    physically ill and depressed. Specifically, Kischnick was unable to provide
    services to her customers for large stretches of time because she was suffering
    from “gynecological problem[s],” which at times were so severe that she doubled
    over in pain.
    Approximately three months after starting to work with Mohler, Kischnick
    departed for the United States with Riechmann. Not once during those three
    months with Mohler was Kischnick able to make a full rental payment, and she
    confided in Mohler that she was earning far less than she had previously.
    7
    Case: 18-10145    Date Filed: 10/07/2019    Page: 8 of 52
    On cross-examination, Mohler admitted that she had never spent any time
    with Riechmann and Kischnick together, and that she had only spoken to him once
    briefly on the phone. She acknowledged that Kischnick had always referred to
    Riechmann as her boyfriend, not her pimp, and consistently denied that she
    supported him financially, as he “had enough money of his own.” Despite the fact
    that the couple had a “very difficult relationship” and “had a lot of fights,” Mohler
    acknowledged that the two “loved each other.” When asked specifically whether
    Riechmann loved Kischnick, Mohler agreed he did, though “not in the same way
    she loved him.” Mohler never saw Riechmann physically abuse Kischnick, nor
    had she seen any evidence that Kischnick was abused. Just prior to departing for
    the United States, Kischnick appeared to be in good health and was looking
    forward to the trip.
    However, on redirect, Mohler stated that: (1) prostitutes often refer to their
    pimps as boyfriends and never admit to supporting them; (2) Kischnick stated
    “very often” than she wanted to stop being a prostitute; (3) Riechmann was
    verbally, if not physically, abusive; and (4) Kischnick would avoid answering any
    time Mohler asked how Riechmann supported himself.
    After the state rested, Riechmann testified on his own behalf and painted a
    different picture of his relationship with Kischnick. Riechmann acknowledged that
    Kischnick had at times worked as a prostitute, but he categorically denied being
    8
    Case: 18-10145     Date Filed: 10/07/2019   Page: 9 of 52
    her pimp or having ever been a pimp at all. According to Riechmann, he was able
    to support himself and his relatively lavish lifestyle through commodities trading,
    particularly oil. Through unspecified means, Riechmann was able to purchase oil
    for less than the OPEC price and resell it in Europe for a profit. Riechmann earned
    a commission of 10 cents per barrel of oil sold.
    As for Kischnick’s occupation, Riechmann maintained she first got into
    prostitution as a means of supporting herself while he was serving a ten-month jail
    sentence for perjury. Riechmann claimed Kischnick ended up in the clutches of “a
    gang of pimps,” and he subsequently “bought her free” by paying the gang six
    months’ worth of her earnings. Kischnick later became involved with another
    gang of pimps when the couple was briefly separated for six months, and
    Riechmann again purchased her freedom for 50,000 German marks.
    During his testimony, Riechmann reiterated his love for Kischnick and
    recounted numerous times he had saved her life. The defense also played for the
    jury a video that Riechmann had taken the night that Kischnick was killed, which
    depicted the two as being in an apparently loving relationship.
    The state trial court allowed the government to impeach Riechmann with
    evidence of his prior German convictions. At the trial, the jury heard about
    Riechmann’s convictions for: (1) grand theft of an automobile stolen in 1966;
    (2) involuntary manslaughter and negligent bodily harm connected with a 1972
    9
    Case: 18-10145       Date Filed: 10/07/2019      Page: 10 of 52
    automobile accident; (3) forgery, which occurred in 1973; and (4) solicitation of
    perjury, which occurred in 1974.
    C. The Murder
    According to Riechmann, he and Kischnick traveled to Miami in 1987 as a
    vacation. The two had previously visited Miami for a week in 1986. While the
    ostensible purpose of the 1987 trip was pleasure, Riechmann was also scoping out
    locations for a designer clothing store he hoped to open in Miami. He and
    Kischnick also took trips to a shooting range during the 1987 trip. Riechmann
    loved to shoot and collect guns, which he was unable to do in Germany.
    Riechmann and Kischnick planned to stay in Miami from October 2 through 31.
    Upon arriving in Miami from Germany in October of 1987, Riechmann
    rented an automobile with his Diner’s Club card, which automatically insured both
    passengers in the event of accidental death. 2 In the event of an accidental death in
    the vehicle—which included homicide—the deceased’s legal heir would receive
    500,000 German marks.3 On the evening of October 25, 1987, following a dinner
    2
    In 1986, Riechmann and Kischnick had twice traveled to Miami before. On at least one
    of those trips, Riechmann similarly rented a car using his Diner’s Club card.
    3
    Records showed that Riechmann and Kischnick had each designated the other as his or
    her legal heir under the policy. Following Kischnick’s murder, the German insurance firm that
    issued the policy received a letter from Riechmann, claiming entitlement to the 500,000 German
    marks due to Kischnick’s death.
    10
    Case: 18-10145     Date Filed: 10/07/2019   Page: 11 of 52
    out, Riechmann drove around the Miami area with Kischnick in the passenger seat
    of the rental car. At some point that evening, Kischnick was shot.
    When questioned by police—both at the scene on the evening of October 25
    and during subsequent conversations—Riechmann consistently claimed Kischnick
    had been shot by a random stranger. Specifically, Riechmann told officers that he
    stopped to ask for directions from a black man who asked if they were tourists.
    Riechmann noticed that the man had something in his hand. Then Riechmann
    heard an explosion. At that point, Riechmann “hit the accelerator and took off.”
    Riechmann heard Kischnick “wheezing” and realized she had been shot, at which
    point he rolled up the window and reclined her seat. He eventually spotted a police
    officer, whom he flagged down. Despite going on multiple “drive arounds” with
    police in the days following the murder, Riechmann was unable to identify
    specifically where the shooting took place.
    In his trial testimony, Riechmann provided a more detailed account of his
    version of events. On the evening of October 25, he and Kischnick had dinner and
    drinks at Bayside in Miami. They left the restaurant at 10:00 p.m., intending to
    stop at the “Welcome to Miami Beach” sign to take pictures, but they got lost. At
    that point, the couple stopped at an unspecified location to ask for directions from a
    stranger. Realizing they were close to their destination, Riechmann unbuckled his
    seatbelt and reached behind his seat to retrieve his video camera, apparently
    11
    Case: 18-10145     Date Filed: 10/07/2019   Page: 12 of 52
    preparing to use it. He placed the camera on Kischnick’s lap while she searched
    her purse for a few dollars to tip the stranger. Riechmann then noticed the stranger
    had approached the car again and “was holding something in his hand into the car.”
    Sensing danger and feeling threatened, Riechmann instinctively “hit the gas pedal”
    and stretched out his arm in a “protective manner.” At the same time Riechmann
    hit the accelerator, he heard an explosion and saw Kischnick slump over in her
    seat. Riechmann then drove around looking for help, eventually spotting a police
    car and flagging it down.
    D. Forensic Evidence
    At trial, the state presented testimony from three expert witnesses: a
    gunshot-residue expert, a firearms expert, and a serologist. The defense also called
    its own gunshot-residue expert to counter the state’s expert.
    When questioning Riechmann at the scene, police swabbed Riechmann’s
    hands. The state’s expert analyzed the swabs and identified numerous particles
    typically found in gunshot residue, the number and nature of which indicated that
    Riechmann had recently fired a gun. The expert specifically testified that he would
    not have expected to find the same number and type of particles on Riechmann’s
    hands if Riechmann had merely sat in the driver’s seat while someone else fired a
    shot from outside the car. In contrast, the defense’s gunshot-residue expert
    testified that the particles of gunshot residue found on Riechmann’s hand proved
    12
    Case: 18-10145       Date Filed: 10/07/2019      Page: 13 of 52
    only that Riechmann was in the vicinity of a gun when it was fired, not that he
    actually fired a gun.
    Upon searching Riechmann’s motel room, police found three handguns and
    40 Winchester silver-tipped, 110 grain, .38-caliber bullets in a 50-shell box.4 An
    expert firearms examiner, who also examined bullet fragments removed from
    Kischnick’s head, testified that the bullets recovered from the motel were the same
    type as the bullet that killed Kischnick, although none of the specific weapons
    found in the room were used to commit the murder. However, the bullet that killed
    Kischnick could only have been fired from one of the following gun models: a .38
    Astra, a .38 Special Taurus revolver, or an FIE .38 Special Derringer. Two of
    those models—the Taurus revolver and the FIE Derringer—were among the three
    guns recovered from Riechmann’s hotel room.
    Riechmann claimed to have bought two of the guns on a prior trip to Miami
    in 1986. During that trip, both Riechmann and the victim took multiple trips to a
    shooting range, and then left the guns with a local attorney they knew when they
    returned to Germany. They retrieved the guns from the attorney by October 9,
    1987. Riechmann bought the third gun on the 1987 trip. Riechmann claimed he
    did so because Kischnick saw it in a magazine and liked it. Riechmann also
    4
    Another two boxes of .38-caliber Winchester ammunition were also discovered in a
    safety deposit box in Germany. The parties stipulated that Riechmann had purchased the safety
    deposit box and was the only person who had access to it.
    13
    Case: 18-10145    Date Filed: 10/07/2019   Page: 14 of 52
    purchased the ammunition on that trip for the two of them to use at the shooting
    range.
    The state also presented testimony from a serologist concerning the blood
    found in the car and on Riechmann’s clothing. The serologist testified that the
    “high-velocity blood splatter” found on the driver-side door inside the car could
    not have gotten there if the driver’s seat was occupied in a normal driving position
    when the shot was fired from outside the passenger-side window. Moreover, upon
    examining Riechmann’s clothing, the serologist discovered blood stains, as
    opposed to high-velocity splatter. Had Riechmann been sitting in the driver’s seat
    during the shooting, his clothes would have shown evidence of blood splatter,
    rather than blood stains, the serologist stated.
    E. Documentary Evidence
    The state also presented several pieces of documentary evidence in support
    of its theory that Riechmann killed Kischnick to recover insurance proceeds. In
    addition to establishing that Riechmann was entitled to 500,000 German marks as a
    result of the insurance policy associated with the rental car, the state presented
    evidence of five additional insurance policies that were taken out on Kischnick’s
    life between approximately 1978 and 1985 and of which Riechmann was the
    beneficiary.
    14
    Case: 18-10145     Date Filed: 10/07/2019   Page: 15 of 52
    Specifically, Riechmann had taken out two life insurance policies on
    Kischnick, each of which insured her life for 200,000 German marks, and one of
    which provided for double payment in the event of accidental death, which
    included murder, so long as the murderer was not the beneficiary. Riechmann was
    the beneficiary of both policies. Riechmann purchased the double-indemnity
    policy from Ernst Steffen in 1984. Steffen had previously sold Riechmann an
    accident insurance policy, but Riechmann wanted to cancel that policy and replace
    it with two risk life insurance policies, one on himself and the other on Kischnick.
    The risk policy on Kischnick (which was for twice as much as the policy on
    Riechmann) insured her only from 1984 to 1994, and Riechmann was only able to
    collect on the policy in the event that Kischnick died within that time frame.
    Additionally, in 1980, while Kischnick and Riechmann were separated,
    Kischnick took out two whole-life policies on herself, which she purchased from
    Ernst Steffen and which were valued at 29,227 and 29,437 German marks,
    respectively, at the time of Kischnick’s death. Both policies provided for double
    indemnity in the event of Kischnick’s accidental death (which, again, included
    murder, assuming the murderer was not the beneficiary). Kischnick’s parents were
    the original beneficiaries on both policies, but in 1983, the insurance company
    received Change of Beneficiary forms designating Riechmann as the new
    beneficiary on both policies.
    15
    Case: 18-10145       Date Filed: 10/07/2019      Page: 16 of 52
    Finally, Riechmann, through his Diner’s Club membership, applied for an
    accidental death and disability policy, which provided for a payout of 500,000
    German marks to Riechmann in the event of Kischnick’s death.5 Following
    Kischnick’s death, Riechmann attempted to collect on at least four of these
    insurance policies. All told, Riechmann stood to gain the equivalent of over
    $961,000 in the event of Kischnick’s accidental death. During his testimony,
    Riechmann claimed to have been unaware that the total payout would be so high.
    Riechmann claimed he was not aware that murder qualified as an accidental death
    under the various policies, nor was he aware of the automatic coverage associated
    with the rental car.
    The state also submitted copies of Riechmann and Kischnick’s reciprocal
    wills, in which each was named as the other’s sole heir. Evidence showed that the
    wills were filed in a German court in June of 1987. Riechmann claimed, during his
    testimony, that it was Kischnick who wanted to file the reciprocal wills.
    5
    The two insurance companies that issued the term life insurance policies also issued
    policies on Riechmann’s life for which Kischnick was the beneficiary, though the payout in the
    event of her death was twice as high. Riechmann also claimed that he had two additional
    policies taken out on his life—one for 100,000 marks and another for 30,000 marks—for which
    Kischnick was the beneficiary. Riechmann testified as to the details of these policies and
    claimed the documentation was in the same safety deposit box in which the German police found
    the other policies, but no actual documentation of the policies on Riechmann’s life was
    submitted into evidence. Moreover, the accidental death and disability policy also covered
    Riechmann in the same amount and actually provided for a higher payout—one million marks—
    in the event of total disability.
    16
    Case: 18-10145     Date Filed: 10/07/2019   Page: 17 of 52
    Riechmann agreed, as he wanted to ensure that Kischnick, not his family, would
    inherit his estate.
    F. Riechmann’s Cell Mate
    While incarcerated pending trial, Riechmann spent two months as a cellmate
    to Walter Symkowski. The two would play chess and discuss their lives. During
    the course of these conversations, Riechmann repeated to Symkowski the same
    version of events he told police and recounted at trial: that he and Kischnick had
    gotten lost and asked a black man for directions, who then shot Kischnick through
    the open window of the car.
    However, Riechmann also told Symkowski that his girlfriend was a “[h]igh
    class prostitut[e]” and that he had paid a Swiss man to marry her so she could
    obtain a Swiss passport. Riechmann said that he never had to work because his
    “[g]irlfriends support him.” Riechmann also expressed happiness at the prospect
    of becoming a millionaire from the insurance money he would receive as a result
    of Kischnick’s death.
    Riechmann denied that he had ever expressed any excitement or jubilation at
    the prospect of receiving insurance payouts. Riechmann claimed Symkowski had
    a reputation in the jail as an informant.
    17
    Case: 18-10145     Date Filed: 10/07/2019   Page: 18 of 52
    G. Verdict and Sentence
    On August 12, 1988, after hearing testimony from over 20 witnesses over
    the course of a month, the jury found Riechmann guilty of first-degree murder and
    possession of a firearm during a criminal offense. No evidence was presented at
    the penalty phase of the trial, and the jury recommended death by a nine-to-three
    vote.
    At the sentencing hearing, after hearing argument from both sides, the state
    trial court issued a verbal ruling on the record. In announcing its ruling, the state
    trial court noted that it had “reviewed certain papers . . . that were delivered to me
    by the State, the reports from Germany.” The state trial court noted that the reports
    concerned “people over in Germany that knew [Riechmann], knew of him.”
    Defense counsel interrupted, informing the state trial court that he had not seen
    those documents and “never got any announcement from the Court as to what the
    Court’s ruling on that matter was,” apparently referring to his pretrial motion to
    have the state trial court review in camera the 27 missing statements from German
    police. In response, the state trial court remarked that “most of the people did not
    know him well and if they knew him well it was years ago.” The state trial court
    then announced its ruling, agreeing with the jury and imposing a sentence of death.
    The state trial court also issued a written sentencing order. Having
    considered the statements from people in Germany who knew Riechmann, the state
    18
    Case: 18-10145     Date Filed: 10/07/2019    Page: 19 of 52
    trial court found that “non-statutory mitigation” was warranted because the
    statements suggested several of the people interviewed “found [Riechmann] to be a
    good person.” However, the state trial court also found the murder was committed
    for pecuniary gain, and was cold, calculated, and premeditated. The state trial
    court ultimately concluded that “[t]he aggravating circumstances far outweigh the
    non-statutory mitigating circumstance,” which was why it agreed with the jury’s
    recommendation to impose a death sentence.
    H. Direct Appeal
    On direct appeal to the Florida Supreme Court, Riechmann raised several
    issues of trial-court and prosecutorial error, none of which is relevant to the
    ineffective assistance or Brady claims presently before us. The Florida Supreme
    Court affirmed Riechmann’s convictions and sentences. Riechmann v. State, 
    581 So. 2d 133
    , 135 (Fla. 1991). The U.S. Supreme Court denied Riechmann’s petition
    for a writ of certiorari on November 2, 1992. Riechmann v. Florida, 
    506 U.S. 952
    ,
    
    113 S. Ct. 405
    (1992).
    II. STATE POST-CONVICTION PROCEEDINGS
    A. Rule 3.850 Motion
    In 1994, Riechmann filed his first motion for post-conviction relief under
    Florida Rule of Criminal Procedure 3.850. Relevant to the instant appeal,
    Riechmann raised two claims: (1) trial counsel failed to adequately investigate the
    19
    Case: 18-10145    Date Filed: 10/07/2019   Page: 20 of 52
    case, including the nature of Riechmann’s relationship with Kischnick; and (2) the
    state withheld material exculpatory evidence, including interviews with 27 German
    and Swiss citizens taken by German police, in violation of Brady.
    The ineffective assistance claim identified 15 potential witnesses, seven of
    whom eventually testified in person at an evidentiary hearing. As to the Brady
    claim, Riechmann’s Rule 3.850 motion made explicit reference to four of the
    witnesses interviewed by German police and the statements taken by the police
    during the course of those interviews.
    B. Evidentiary Hearing and Ruling
    The state 3.850 court held an evidentiary hearing, at which Riechmann
    presented in-person testimony from seven German witnesses. These witnesses
    maintained they would have been willing to testify at trial had they been contacted.
    While several witnesses testified that Riechmann seemed to have money—because
    he was well dressed, paid the rent on time, or paid for dinners—none of these
    witnesses had personal knowledge of Riechmann’s financial situation or of any
    actual employment. Several of the witnesses did, however, testify that Riechmann
    had led them to believe he worked as an insurance agent.
    Two of the witnesses, Doris Dessauer and Doris Rindelaub, were former
    girlfriends of Riechmann and had no contact at all with Kischnick. Although she
    had been Riechmann’s girlfriend from 1971 to 1978, Dessauer conceded she had
    20
    Case: 18-10145       Date Filed: 10/07/2019       Page: 21 of 52
    no idea “what went on in the relationship between . . . Kischnick and
    [Riechmann].” She admitted that she was convicted of perjury after she falsely
    testified on Riechmann’s behalf concerning a traffic infraction. 6 For her part,
    Rindelaub, who dated Riechmann for six months, conceded that “there are a lot of
    things that [she] [didn’t] know about . . . Riechmann.”
    Even the five witnesses who testified that Riechmann appeared to have a
    good or loving relationship with Kischnick conceded that their contacts with
    Kischnick and their observations of the couple were quite limited or not recent.
    For example, sisters Marlene and Monika Seeger rented one of their many
    apartments to Riechmann from 1984 through his conviction. Kischnick moved in
    with him later, and Riechmann always paid the rent on time. Yet both sisters
    acknowledged that they never even had a conversation with Kischnick beyond
    exchanging pleasantries, and their interactions with Riechmann largely were
    limited to brief conversations when he paid the rent.
    Martin and Ulrike Karpischek, a couple who operated a high-end hair salon
    in Germany, also testified about their limited interactions with Kischnick.
    Riechmann was one of the approximately 2,500 customers at their salon. Their
    interactions with Kischnick primarily occurred when she came to the salon to pick
    6
    This led to Riechmann’s conviction for solicitation of perjury, which the state submitted
    as evidence during Riechmann’s trial.
    21
    Case: 18-10145        Date Filed: 10/07/2019        Page: 22 of 52
    up Riechmann. Kischnick had been to the salon on her own only occasionally.
    Neither Martin nor Ulrike had any contact with Riechmann or Kischnick outside
    the salon. Despite this limited contact, Ulrike claimed that Kischnick “had no
    desire to quit being a prostitute.”
    The last witness was Wolfgang Walitzki, a friend of Riechmann and
    Kischnick’s. He met the couple around 1978, and would go on day trips with them
    and attend dinners at their home. While he had no direct knowledge of what
    Riechmann did for a living, Walitzki spoke vaguely of a business deal Riechmann
    had apparently entered into with an “Arabian fellow.” Once the couple moved to
    southern Germany, his contact with them was limited, and he could recall only one
    specific instance in which he had seen them in the two years preceding Kischnick’s
    murder.7
    7
    In addition to the seven witnesses who testified in person, Riechmann submitted the
    affidavits of eight additional witnesses who were unable to testify in person. Riechmann offered
    the affidavits as evidence that would have been presented “for purposes of mitigation” during the
    penalty phase. The state 3.850 court admitted the affidavits solely for the purpose of determining
    whether counsel performed deficiently at the penalty stage, and it considered them only for that
    purpose. Because we are reviewing only Riechmann’s guilt-phase claims, we need not consider
    the content of those affidavits here.
    Further, we reject Riechmann’s claim that the affidavits were admitted for purposes of
    the guilt-phase claims too. The record shows that, at the 3.850 hearing, the state challenged the
    admission of the affidavits as containing hearsay without any showing of reliability.
    Riechmann’s attorney responded that the statements would be “proffered as mitigation evidence”
    and that there were “relaxed hearsay and relaxed evidentiary standards for purposes of
    mitigation.” The parties specifically discussed the admissibility of the affidavits under the
    standard in Fla. Stat. § 921.141, which concerns sentencing proceedings for capital felonies and
    allows a state court to admit evidence probative of the character of the defendant regardless of its
    admissibility under the exclusionary rules of evidence. After hearing the parties’ arguments, the
    state 3.850 court admitted the affidavits into evidence as relevant to whether counsel was
    22
    Case: 18-10145        Date Filed: 10/07/2019        Page: 23 of 52
    As to Riechmann’s Brady claim, the state 3.850 court also admitted five
    written statements taken by German police that were withheld from the defense. 8
    But three of those statements came from persons who also testified in person at the
    evidentiary hearing, and their statements were largely repetitive of that testimony.9
    The fourth statement came from Dr. Horst Neumann, a retired physician who
    thought Riechmann and Kischnick, as a couple, were “financially quite well-off,”
    in part because they offered him a generous amount to take care of their dogs when
    they were away on trips. Riechmann told Dr. Neumann that he had won 40,000
    German marks in the lottery.10
    ineffective by not investigating these potential statements prior to sentencing. The state 3.850
    court noted that it was not necessary for it to conclude, at that point, whether the affidavits would
    necessarily have been admissible in a hypothetical sentencing proceeding.
    8
    According to the state 3.850 court’s order, of the 27 statements that the state failed to
    disclose to the defense, only five were actually introduced into evidence. The state 3.850 court’s
    order actually references nine “reports” that were introduced, but four of the exhibits it
    references are not witness statements but other documentary evidence the state had in its
    possession.
    9
    Because the statements themselves have not been provided as part of the state-court
    record, we rely on Riechmann’s Rule 3.850 motion—which quotes extensively from the
    statements—in assessing the content of the withheld statements.
    10
    The fifth statement was from Karl-Heinz Dreyer. Riechmann made no reference to this
    statement in his Rule 3.850 motion or during the course of the instant federal habeas proceeding.
    The state 3.850 court also admitted several documents that the state similarly withheld.
    As relevant here, those documents included: (1) a letter (which we discuss later) from the
    company Hch. Vollenweider Truhand, dated October 25, 1985, that allegedly documents
    Kischnick’s gainful employment in a business other than prostitution; and (2) a lottery winnings
    receipt.
    23
    Case: 18-10145        Date Filed: 10/07/2019       Page: 24 of 52
    Following the hearing, the state 3.850 court rejected the majority of
    Riechmann’s claims, but vacated his death sentence and ordered a new sentencing
    hearing based on: (1) the trial judge’s inappropriate ex parte communication with
    the prosecutor, through which the judge delegated to the prosecutor responsibility
    for writing the sentencing order; and (2) ineffective assistance of counsel at the
    penalty phase only.11
    As to Riechmann’s claim that his trial counsel was ineffective at the guilt
    phase, the state 3.850 court found that Riechmann failed to demonstrate prejudice
    resulting from trial counsel’s failure to investigate and present evidence of
    Riechmann’s relationship with Kischnick. Specifically, the state 3.850 court found
    that most of the evidence Riechmann identified—in-person testimony from seven
    of the witnesses on the list Riechmann provided to trial counsel before trial—“had
    already been presented to the jury, although in a manner different from now
    desired.” It determined that counsel’s decision to rely on the evidence presented at
    trial was a “tactical and strategic” decision that did not constitute ineffective
    11
    In finding that Riechmann’s trial counsel performed deficiently as to the penalty phase,
    the state 3.850 court noted that: (1) “trial counsel failed to renew or pursue his motion to obtain
    the German and Swiss statements which would have provided him with mitigating evidence to
    present to the jury”; and (2) “trial counsel’s sentencing investigation was patently inadequate,”
    and he offered no reasonable explanation for his failure to search for mitigating evidence. As a
    result of trial counsel’s deficient performance, he “failed to unearth a large amount of mitigating
    evidence as to [Riechmann’s] character, family history and relationship with the victim,” thus
    prejudicing Riechmann.
    24
    Case: 18-10145     Date Filed: 10/07/2019   Page: 25 of 52
    assistance of counsel. The state 3.850 court specifically declined to make any
    findings “concerning any deficiency [of defense counsel] in the guilt phase.”
    As to the Brady claim, the state 3.850 court found that the German witness
    statements were “known to the State and, without dispute, were favorable to the
    defense,” and Riechmann “did not otherwise have ready access to the Swiss and
    German persons involved (even assuming he knew who they all were).” As to
    materiality, the state 3.850 court found that “the State’s evidentiary suppression
    undermines confidence in the outcome of the penalty phase, although there is no
    reasonable probability of a different result in the guilt phase.” Although the state
    3.850 court found that “a Brady violation had occurred during the penalty phase,”
    it ultimately said Riechmann could not raise the Brady claim in the Rule 3.850
    proceeding “because it could have been raised on direct appeal.”
    C. Appeal
    The state appealed to the Florida Supreme Court, challenging the state 3.850
    court’s decision to order resentencing, and Riechmann cross-appealed, challenging
    the state 3.850 court’s rejection of his remaining claims as to the guilt phase. The
    Florida Supreme Court affirmed the state 3.850 court’s ruling, including its
    decision to vacate Riechmann’s death sentence and to order resentencing. State v.
    Riechmann, 
    777 So. 2d 342
    , 347 (Fla. 2000).
    25
    Case: 18-10145     Date Filed: 10/07/2019   Page: 26 of 52
    As to Riechmann’s guilt-phase ineffective assistance claim, the Florida
    Supreme Court agreed with the state 3.850 court’s finding that Riechmann failed to
    demonstrate prejudice because the claim “concerned evidence which was already
    admitted at trial, only in a different manner than now asserted.” 
    Id. at 357
    (“[W]e
    find that the trial judge’s factual findings are supported by competent and
    substantial evidence, and his legal conclusions are supported by our prior case
    law.”). In particular, the Florida Supreme Court pointed to “testimony from a
    State’s witness of Riechmann’s love for Kischnick” and “a videotape of the couple
    the night of the murder that showed them involved in a loving relationship.” 
    Id. The Florida
    Supreme Court went on to note that, in any case, “counsel could
    not be held ineffective for failing to present witnesses from a list withheld from
    him.” 
    Id. In a
    footnote, the Florida Supreme Court clarified that it was referring to
    the list of Swiss and German witnesses that the state withheld which formed the
    basis of Riechmann’s Brady claim. 
    Id. at 357
    n.16.
    In addressing the Brady claim, the Florida Supreme Court agreed with the
    state 3.850 court’s finding that the witness statements withheld by the state “would
    have been material to Riechmann in the sentencing phase” and noted that “these
    statements will be made available to Riechmann” for “the new penalty phase.” 
    Id. at 363.
    Notably, however, the Florida Supreme Court did not indicate that its
    decision to affirm the state 3.850 court and order resentencing was based on the
    26
    Case: 18-10145      Date Filed: 10/07/2019    Page: 27 of 52
    Brady violation, nor did it express disagreement with the state 3.850 court’s
    finding that the penalty-phase Brady claim was barred because Riechmann failed
    to raise it on direct appeal. 
    Id. Instead, the
    Florida Supreme Court explicitly stated
    it was affirming the state 3.850 court’s order “in its entirety,” before specifically
    agreeing with the state 3.850 court’s analysis concerning the ex parte
    communication and counsel’s deficient performance during the penalty phase. 
    Id. at 347,
    348–53.
    As to the guilt-phase Brady claim, the Florida Supreme Court concluded that
    the claim was “procedurally barred because [Riechmann] could and should have
    raised it on direct appeal, since by trial’s end he was aware of the statements.” 
    Id. at 363.
    In any case, the Florida Supreme Court also explicitly agreed with the state
    3.850 court’s finding “that even if disclosed, there was no reasonable probability
    that a different result would have occurred” in the guilt phase. 
    Id. In the
    same opinion, the Florida Supreme Court also denied a separate state
    habeas corpus petition filed by Riechmann, in which he had raised, inter alia, the
    same Brady claim raised in his Rule 3.850 motion and a claim for ineffective
    assistance of appellate counsel. 
    Id. at 364–66,
    364 nn.21–22.
    27
    Case: 18-10145       Date Filed: 10/07/2019      Page: 28 of 52
    On February 1, 2010, Riechmann was resentenced to life imprisonment for
    first-degree murder.12 The Florida Third District Court of Appeal affirmed per
    curiam. Riechmann v. State, 
    83 So. 3d 734
    (Fla. Dist. Ct. App. 2012).
    III. FEDERAL HABEAS PROCEEDINGS
    A. § 2254 Petition
    In March 2013, Riechmann filed a counseled § 2254 petition, raising several
    claims, including the guilt-phase claims of ineffective assistance and Brady
    violations detailed above. As to the ineffective assistance claim, Riechmann
    challenged the Florida Supreme Court’s factual finding that the information trial
    counsel could have gathered from further investigation would have been
    cumulative.
    In addressing the Florida Supreme Court’s resolution of his Brady claim,
    Riechmann made little effort to address the Florida Supreme Court’s conclusion
    that his Brady claim was procedurally barred. Instead, Riechmann offered a brief
    argument concerning the materiality of the evidence, maintaining that the
    statements from the German witnesses would have undermined the state’s
    evidence of motive during the guilt phase. The only reference Riechmann made to
    12
    Riechmann filed a second Rule 3.850 motion during the pendency of the appeal of the
    first, raising claims not pertinent to the instant appeal. Riechmann’s resentencing was stayed
    pending the resolution of the second motion, the denial of which was affirmed in 2007.
    Riechmann v. State, 
    966 So. 2d 298
    , 301 (Fla. 2007).
    28
    Case: 18-10145     Date Filed: 10/07/2019   Page: 29 of 52
    the Florida Supreme Court’s procedural ruling was to assert, in a footnote, that
    “[t]o the extent that the [Florida Supreme C]ourt determined that issue is
    procedurally barred as it should have been raised on direct appeal, then counsel
    was ineffective.”
    B. Report & Recommendation, Objections, and Final Judgment
    A magistrate judge prepared a report and recommendation (“R&R”),
    recommending that the district court deny Riechmann’s § 2254 petition. In
    relevant part, the magistrate judge concluded Riechmann was not entitled to
    federal habeas relief on his ineffective assistance claim because “[t]he Florida
    Supreme Court accurately stated that the [state 3.850] court’s factual findings on
    the claim concerning Riechmann’s relationship with Kischnick were supported by
    competent and substantial evidence, and the legal conclusions were supported by
    prior case law.” As to Riechmann’s Brady claim, the magistrate judge concluded
    that the claim was procedurally barred, and Riechmann failed to show cause and
    prejudice sufficient to overcome that bar. The magistrate judge further noted that
    Riechmann’s § 2254 petition failed to provide any substantive analysis as to the
    Brady claim; in particular, he failed even to allege that the Florida Supreme Court
    unreasonably applied federal law in rejecting his Brady claim.
    In his objections to the R&R, Riechmann argued for the first time that the
    procedural bar should not apply because the particular procedural rule invoked by
    29
    Case: 18-10145       Date Filed: 10/07/2019      Page: 30 of 52
    the Florida Supreme Court was not “adequate” to bar federal habeas relief,
    primarily because, he asserted, Florida courts did not consistently apply the
    identified procedural rule.
    After considering Riechmann’s objections and conducting a de novo review
    of the record, the district court affirmed and adopted the R&R, and denied
    Riechmann’s § 2254 petition. Riechmann appealed, and this Court granted a COA
    as to whether the district court had properly denied § 2254 habeas relief on
    Riechmann’s ineffective assistance and Brady claims.
    IV. DISCUSSION 13
    The Antiterrorism and Effective Death Penalty Act of 1996 (“AEDPA”)
    provides that, after a state court has adjudicated a claim on the merits, a federal
    court may grant habeas relief only if the state court’s decision was (1) “contrary to,
    or involved an unreasonable application of, clearly established [f]ederal law, as
    determined by the Supreme Court,” or (2) “based on an unreasonable
    determination of the facts in light of the evidence presented in the [s]tate court
    proceeding.” 28 U.S.C. § 2254(d)(1), (2).
    13
    “We review de novo a district court’s denial of a § 2254 petition.” Bester v. Warden,
    
    836 F.3d 1331
    , 1336 (11th Cir. 2016). In an appeal brought by an unsuccessful habeas petition,
    the scope of our review is limited to the issues specified in the COA. Murray v. United States,
    
    145 F.3d 1249
    , 1251 (11th Cir. 1998).
    30
    Case: 18-10145     Date Filed: 10/07/2019    Page: 31 of 52
    The decision of a state court is “contrary to” federal law only if it
    “contradicts the United States Supreme Court on a settled question of law or holds
    differently than did that Court on a set of materially indistinguishable facts.”
    Cummings v. Sec’y for Dep’t of Corr., 
    588 F.3d 1331
    , 1355 (11th Cir. 2009)
    (internal quotation marks omitted) (quoting Kimbrough v. Sec’y, 
    565 F.3d 796
    ,
    799 (11th Cir. 2009)). A federal court making an “unreasonable application”
    inquiry should ask whether the state court’s application of clearly established
    federal law was objectively unreasonable. Bell v. Cone, 
    535 U.S. 685
    , 694, 122 S.
    Ct. 1843, 1850 (2002) (internal quotation marks omitted) (quoting Williams v.
    Taylor, 
    529 U.S. 362
    , 404–05, 
    120 S. Ct. 1495
    , 1519 (2000)).
    A. Ineffective Assistance of Trial Counsel
    Riechmann contends his trial counsel’s performance at the guilt-phase of
    trial was constitutionally ineffective under the standards set forth in Strickland v.
    Washington, 
    466 U.S. 668
    , 
    104 S. Ct. 2052
    (1984). Riechmann argues trial
    counsel failed to conduct an adequate investigation when he did not interview
    several German witnesses on a list that Riechmann provided to him prior to trial.
    “An ineffective assistance claim has two components: A petitioner must show that
    counsel’s performance was deficient, and that the deficiency prejudiced the
    defense.” Wiggins v. Smith, 
    539 U.S. 510
    , 521, 
    123 S. Ct. 2527
    , 2535 (2003).
    31
    Case: 18-10145     Date Filed: 10/07/2019   Page: 32 of 52
    At the outset, we must determine whether the Florida Supreme Court’s
    resolution of Riechmann’s ineffective assistance claim is entitled to deferential
    review under AEDPA. Riechmann contends that we should review his ineffective
    assistance claim de novo because the Florida Supreme Court’s conclusions
    regarding both deficiency and prejudice were based on an unreasonable
    determination of the facts in light of the evidence presented.
    “Federal habeas courts generally defer to the factual findings of state courts,
    presuming the facts to be correct unless they are rebutted by clear and convincing
    evidence.” Cooper v. Sec’y, Dep’t of Corr., 
    646 F.3d 1328
    , 1352–53 (11th Cir.
    2011) (internal quotation marks omitted) (quoting Jones v. Walker, 
    540 F.3d 1277
    ,
    1288 n.5 (11th Cir. 2008) (en banc)). However, “[w]hen a state court’s
    adjudication of a habeas claim results in a decision that is based on an
    unreasonable determination of the facts in light of the evidence presented in the
    State court proceeding, this Court is not bound to defer to unreasonably-found facts
    or to the legal conclusions that flow from them.” 
    Id. at 1353
    (internal quotation
    marks omitted) (quoting 
    Jones, 540 F.3d at 1288
    n.5). In such instances, we need
    not afford the state court’s findings deference under AEDPA, and we review the
    underlying habeas claim de novo. 
    Id. As to
    deficient performance, Riechmann correctly notes that the Florida
    Supreme Court appears to have somewhat mischaracterized the basis for his
    32
    Case: 18-10145      Date Filed: 10/07/2019    Page: 33 of 52
    ineffective assistance claim in its deficiency ruling. After agreeing with the state
    3.850 court’s prejudice analysis, the Florida Supreme Court noted that, in any case,
    “counsel could not be held ineffective for failing to present witnesses from a list
    withheld from him” by the state. 
    Riechmann, 777 So. 2d at 357
    . But the relevant
    list for purposes of Riechmann’s ineffective assistance claim was the list he
    provided to defense counsel of witnesses to find and interview, not the list of
    witnesses interviewed by German police. And, while there was considerable
    overlap between the two lists, Riechmann’s list included several names—including
    Marlene Seeger, Wolfgang Walitzki, and the Karpischeks—who were not on the
    state’s list. Additionally, it was the statements themselves, not the list of
    witnesses, that the state actually withheld from the defense.
    Thus, to the extent that the Florida Supreme Court based its
    deficient-performance ruling on its finding that defense trial counsel had no way of
    identifying any or all of the witnesses on the state’s list who were then identified in
    Riechmann’s 3.850 motion for relief, that ruling was based on an unreasonable
    determination of the facts, and it is not entitled to deferential review under
    AEDPA. See 
    Cooper, 646 F.3d at 1352
    –53.
    However, the Florida Supreme Court did not solely, or even primarily, rest
    its rejection of Riechmann’s ineffective assistance claim on its finding that counsel
    did not perform deficiently. Rather, its primary basis for rejecting that claim was
    33
    Case: 18-10145    Date Filed: 10/07/2019    Page: 34 of 52
    Riechmann’s failure to show that he was prejudiced by defense counsel’s allegedly
    deficient performance. Riechmann insists this conclusion similarly is not entitled
    to deferential review because the Florida Supreme Court unreasonably determined
    that the testimony defense counsel could have elicited from the absent witnesses
    would have been cumulative.
    As discussed above, the Florida Supreme Court explicitly pointed to two
    pieces of trial evidence in support of its finding that the additional testimony
    defense counsel failed to present would be cumulative: the testimony of Dina
    Mohler—specifically her testimony that Riechmann and Kischnick loved one
    another—and the video the defense played for the jury, which showed Riechmann
    and Kischnick involved in a loving relationship.
    These are, generally speaking, the sentiments Riechmann claims the absent
    witnesses he identifies would have communicated to the jury about the nature of
    Riechmann and Kischnick’s relationship had trial counsel bothered to find and call
    them. We acknowledge that Mohler made various concessions during her
    testimony—including that Riechmann did not love Kischnick “in the same way she
    loved him”—that undermined some of her more positive testimony. But it
    remains the case that the jury was presented with testimony expressing the basic
    sentiments that Riechmann claims would have come from the absent witnesses he
    identifies.
    34
    Case: 18-10145       Date Filed: 10/07/2019      Page: 35 of 52
    A review of the evidence presented at the Rule 3.850 evidentiary hearing
    reveals that much of the desired testimony was repetitious and would have
    communicated that Riechmann and Kischnick appeared to be in a loving
    relationship, and that Riechmann was financially independent and did not “live
    off” of Kischnick’s income from prostitution. Indeed, the jury already saw
    firsthand from the video the nature of their relationship, loving or otherwise. As a
    result, we cannot say that the Florida Supreme Court’s finding that the potential
    additional testimony—to the extent it would have been admissible under the
    Florida Rules of Evidence—was cumulative is a wholly unreasonable
    determination of the facts in light of the evidence presented. See 28 U.S.C.
    § 2254(d)(2); 
    Cooper, 646 F.3d at 1352
    –53.
    Additionally, our exhaustive review of the record reveals that other state
    witnesses offered testimony—on both direct and cross-examination—that similarly
    undermined the state’s theory of motive, particularly as it concerned Riechmann’s
    financial situation. 14 For example, at trial, Steffen testified that he helped
    Riechmann rent a luxury apartment by verifying a certificate of earnings showing
    Riechmann’s monthly income. Steffen also stated, like several of the witnesses
    14
    While the Florida Supreme Court pointed to only two pieces of evidence—a fact
    Riechmann focuses on in his brief—it specifically stated that those pieces of evidence were
    merely examples of evidence that accomplished the same purpose as the 3.850 testimony
    Riechmann asserted would have been elicited from the absent witnesses he identified.
    35
    Case: 18-10145    Date Filed: 10/07/2019   Page: 36 of 52
    who testified at the 3.850 evidentiary hearing, that Riechmann claimed to have
    been trained as an insurance agent.
    Kischnick’s sister, Regina, recalled Kischnick telling her that Riechmann
    had “business dealings with Arabs,” testimony that mirrors statements presented in
    the evidentiary hearing concerning Riechmann’s dealings with Saudi businessmen.
    On cross-examination, Regina also conceded that Riechmann and Kischnick’s
    lavish lifestyle likely was not supported by Kischnick’s income alone. Thus, the
    jury was hardly deprived of testimony concerning Riechmann’s sources of income
    beyond Kischnick’s prostitution.
    Riechmann also had the opportunity to explain the nature of his relationship
    with Kischnick and the source of his financial success to the jury when he testified
    in his own defense. For example, Riechmann explained that, far from forcing
    Kischnick to engage in prostitution, he had in fact bought her freedom from other
    pimps on two occasions.
    In any case, even assuming that we found the Florida Supreme Court’s
    finding that the proffered evidence was cumulative to be unreasonable and
    reviewed Riechmann’s ineffective assistance claim de novo, we would nonetheless
    affirm on the ground that Riechmann failed to demonstrate prejudice resulting
    from trial counsel’s deficient performance.
    36
    Case: 18-10145      Date Filed: 10/07/2019    Page: 37 of 52
    Assuming the testimony Riechmann relies on would have been admissible at
    trial to rebut the state’s theory of motive, there is no reasonable probability that
    admission of that testimony would have changed the outcome at trial. See
    
    Strickland, 466 U.S. at 694
    , 104 S. Ct. at 2068 (To demonstrate prejudice, a
    petitioner must show that there is a “reasonable probability that, but for counsel’s
    unprofessional errors, the result of the proceeding would have been different.”).
    As Riechmann acknowledges, the 3.850 testimony and evidence he claims
    competent counsel would have elicited from the identified witnesses would have
    been in response to only the state’s evidence of motive. The absent testimony
    therefore would have done nothing to undermine the state’s circumstantial forensic
    evidence, which included the following: (1) bullets recovered from Riechmann’s
    motel room matched the type used to kill Kischnick; (2) Riechmann possessed two
    of the only three models of guns that could have been used to kill Kischnick;
    (3) the presence of gunshot residue on Riechmann’s hands that, according to the
    state’s expert, established to a reasonable degree of scientific certainty that he had
    fired a gun; and (4) blood splatter evidence that, according to the state’s expert,
    was inconsistent with Riechmann’s claim that he was in the car when Kischnick
    was shot.
    Moreover, even as to the state’s theory of motive, the 3.850 testimony that
    would have been elicited from the witnesses Riechmann identifies was weak and
    37
    Case: 18-10145    Date Filed: 10/07/2019   Page: 38 of 52
    would not have effectively undermined the state’s motive theory. Of the seven
    witnesses whose testimony Riechmann presented at the evidentiary hearing before
    the state 3.850 court, only Wolfgang Walitzki appears to have spent any significant
    time with Riechmann and Kischnick as a couple. Both Marlene and Monika
    Seeger confessed that they never had an actual conversation with Kischnick
    beyond exchanging pleasantries, and their interactions with Riechmann were
    largely confined to the times when he would come to pay his rent. Their respective
    impressions of Riechmann and Kischnick’s relationship were formed through
    observing the couple’s rapport “from a distance.”
    Similarly, the Karpischeks, whose testimony Riechmann repeatedly
    references on appeal, both admitted that their interactions with Riechmann and
    Kischnick as a couple primarily occurred when Kischnick would come to pick up
    Riechmann from his hair appointments. Notably, they had no contact with
    Riechmann or Kischnick outside of the salon. Riechmann makes much of Ulrike
    Karpischek’s testimony that she knew “for a fact” that Kischnick “had no desire to
    quit being a prostitute.” But Ulrike provided no basis for her purported intimate
    knowledge of Kischnick’s “desire[s].” Rather, her testimony revealed that both
    she and her husband had limited contact with Riechmann and Kischnick, who,
    after all, were but two of the Karpischeks approximately 2,500 customers.
    38
    Case: 18-10145     Date Filed: 10/07/2019   Page: 39 of 52
    Doris Dessauer and Doris Rindelaub, Riechmann’s former girlfriends,
    admitted they had never met Kischnick, and both testified they had barely heard
    from or seen Riechmann in many years. As to Walitzki, while he at least testified
    to a friendship with Riechmann and Kischnick, even he acknowledged that he had
    lost contact with them once they relocated to southern Germany in the years
    immediately preceding Kischnick’s murder.
    As for the testimony concerning Riechmann’s financial situation, none of the
    seven witnesses testified to having any direct knowledge of Riechmann’s finances
    or his various business ventures. Rather, they testified that they simply believed
    him to be financially secure because he generally appeared to be well off, dressed
    well, did not have trouble making rent payments, often picked up the tab at dinner,
    and spoke vaguely of his business activities. Importantly, these observations are
    not even necessarily inconsistent with the state’s theory. The fact that Riechmann
    appeared to be well-off does not preclude the possibility that his financial comfort
    was due, at least in part, to Kischnick’s income from prostitution.
    Several of the seven witnesses also testified that Riechmann had represented
    to them that he was an insurance salesman. The ostensible benefit of such
    testimony at trial would have been to indicate to the jury that Riechmann had an
    independent source of income and therefore did not need the income from
    Kischnick’s prostitution. But Riechmann himself at least partially contradicted this
    39
    Case: 18-10145     Date Filed: 10/07/2019    Page: 40 of 52
    testimony in his own trial testimony, during which he claimed he was able to
    support himself largely through commodities trading and admitted to lying, in a
    loan application, about working for an insurance company.
    What’s more, the jury still would have been presented with evidence of the
    reciprocal wills and insurance policies on Kischnick’s life from which Riechmann
    stood to benefit. That Riechmann stood to profit greatly from Kischnick’s death—
    to the tune of over $961,000 in U.S. dollars—was further evidence of motive that
    the testimony of Riechmann’s German acquaintances would have done little to
    counteract. And, in fact, Riechmann did attempt to collect on a number of the
    policies following Kischnick’s murder. The jury also heard from Riechmann’s cell
    mate that Riechmann expressed happiness at the prospect of becoming a
    millionaire from the insurance money he would receive.
    On balance then, we are convinced that whatever marginal benefit would
    have accrued to Riechmann as a result of the 3.850 testimony did not create a
    “reasonable probability that, but for counsel’s unprofessional errors, the result of
    the proceeding would have been different.” See 
    Strickland, 466 U.S. at 694
    , 104
    S. Ct. at 2068.
    B. Brady Violation
    Riechmann also contends that the state’s withholding of the statements of 27
    Swiss and German citizens was violative of Brady v. Maryland. Before we address
    40
    Case: 18-10145     Date Filed: 10/07/2019    Page: 41 of 52
    the merits of this claim, we must first consider whether the district court properly
    found that his Brady claim was procedurally barred. Riechmann asserts that we
    should review his Brady claim on the merits because the procedural bar invoked by
    the Florida Supreme Court was not actually adequate to bar his claim.
    1. Procedural Bar
    “A state habeas corpus petitioner who fails to raise his federal claims
    properly in state court is procedurally barred from pursuing the same claim in
    federal court absent a showing of cause for and actual prejudice from the default.”
    Bailey v. Nagle, 
    172 F.3d 1299
    , 1302 (11th Cir. 1999). Thus, where a state court
    “clearly and expressly” rests its rejection of a claim on a procedural bar, and that
    bar “provides an adequate and independent state ground for denying relief,” federal
    review of that claim is barred by the procedural default doctrine. Atkins v.
    Singletary, 
    965 F.2d 952
    , 956 (11th Cir. 1992) (internal quotation marks omitted)
    (quoting Johnson v. Singletary, 
    938 F.2d 1166
    , 1173 (11th Cir. 1991) (en banc)).
    A state procedural rule is not “adequate” to bar federal habeas review when it is
    not “strictly or regularly followed” by the state courts. Hathorn v. Lovorn, 
    457 U.S. 255
    , 263, 
    102 S. Ct. 2421
    , 2426 (1982) (internal quotation marks omitted)
    (quoting Barr v. City of Columbia, 
    378 U.S. 146
    , 149, 
    84 S. Ct. 1734
    , 1736
    (1964)).
    41
    Case: 18-10145    Date Filed: 10/07/2019    Page: 42 of 52
    Here, the Florida Supreme Court “clearly and expressly” rested its rejection
    of Riechmann’s guilt-phase Brady claim on a state procedural bar, pursuant to
    which issues that were or could have been raised on direct appeal are barred in
    state post-conviction proceedings. 
    Riechmann, 777 So. 2d at 363
    (citing Francis v.
    Barton, 
    581 So. 2d 583
    (Fla. 1991)). Because Riechmann could have raised his
    Brady claim on direct appeal—a finding he has not contested—the Florida
    Supreme Court determined the claim was barred. 
    Id. Riechmann continues
    to insist that this procedural rule is not “strictly or
    regularly followed.” Riechmann’s primary, if not only, basis for this assertion is
    that the Florida Supreme Court did not apply the rule consistently within his case.
    Riechmann argues that, had the Florida Supreme Court been consistent, it would
    similarly have rejected his penalty-phase Brady claim on the same procedural
    ground, which it did not. We find this argument lacks merit, as it is based on a
    fundamental misreading of the Florida Supreme Court’s opinion. In discussing the
    statements in question, the Florida Supreme Court correctly noted that “the [state
    3.850] court found that these statements would have been material to Riechmann in
    the sentencing phase because they would have allowed counsel the opportunity to
    present some mitigating evidence.” 
    Riechmann, 777 So. 2d at 363
    . It went on to
    say it agreed with that determination and that the statements would be made
    available to Riechmann “for the new penalty phase.” 
    Id. 42 Case:
    18-10145      Date Filed: 10/07/2019    Page: 43 of 52
    Riechmann characterizes these statements as the Florida Supreme Court
    granting him relief as to his penalty-phase Brady claim. Not so. The Florida
    Supreme Court at no point stated that its affirmance of the state 3.850 court’s
    decision ordering resentencing was based on the Brady claim. Rather, it merely
    expressed agreement with the state 3.850 court’s finding that the statements were
    Brady material that would need to be turned over during the subsequent
    resentencing. 
    Id. Moreover, the
    Florida Supreme Court expressly stated that it “affirm[ed] the
    [state 3.850] court’s order in its entirety” before specifically discussing the state
    3.850 court’s two actual bases for ordering resentencing—ineffective assistance
    and improper ex parte communications between the sentencing judge and the
    prosecutors. 
    Id. at 347–53
    (emphasis added). While the Florida Supreme Court
    did not explicitly agree with the state 3.850 court’s ruling that the penalty-phase
    Brady claim was procedurally barred, it did note that the state 3.850 court had
    “denied the remainder of Riechmann’s claims,” and expressed no disagreement
    with any part of that decision. 
    Id. at 348.
    Riechmann claims that the Florida Supreme Court implicitly ruled on the
    penalty-phase Brady claim when it ordered that the previously withheld statements
    be made available at his resentencing. According to Riechmann, had the Florida
    Supreme Court applied the procedural bar to his penalty-phase claim, it would not
    43
    Case: 18-10145   Date Filed: 10/07/2019    Page: 44 of 52
    have had any reason to comment on the materiality of the statements. “Rather, it
    would have rejected the claim entirely, and . . . Riechmann would have had to
    proceed at his penalty retrial without the statements.” This is incorrect.
    Both the state 3.850 court and the Florida Supreme Court acknowledged that
    the state likely violated Brady at the penalty phase by withholding the statements,
    but neither was willing to grant relief on that basis due to the procedural bar. This
    did not somehow relieve the state of its obligation to comply with Brady during the
    new penalty trial, regardless of whether the new sentencing proceeding was based
    on its prior failure to do so. There is no inconsistency to be found in a court
    acknowledging that an otherwise procedurally barred claim is or may be
    meritorious.
    Because Riechmann’s argument that the Florida Supreme Court did not
    “strictly or regularly follow[]” its own procedural rule in its opinion is without
    merit, we conclude that the district court properly deferred to that procedural
    ruling, and Riechmann may maintain a claim for federal habeas relief only if he
    can show cause and prejudice to excuse his failure to properly exhaust his
    guilt-phase Brady claim. 
    Bailey, 172 F.3d at 1302
    .
    However, Riechmann likely has abandoned any argument regarding the
    district court’s finding that he failed to sufficiently allege that he could show cause
    and prejudice sufficient to overcome the procedural default. In his initial brief on
    44
    Case: 18-10145        Date Filed: 10/07/2019        Page: 45 of 52
    appeal, Riechmann focuses his argument concerning procedural default solely on
    whether the procedural bar invoked by the Florida Supreme Court was adequate to
    bar relief. This is despite clear language in this Court’s COA order stating that
    “[w]hile the district court correctly determined that Riechmann’s Brady claim was
    procedurally defaulted, . . . reasonable jurists could debate the district court’s
    further determination that he failed to overcome that default.”
    Because Riechmann has failed to plainly and prominently offer any
    argument as to whether he established cause and prejudice to excuse the procedural
    default of his Brady claim, he has effectively abandoned the claim. See United
    States v. Jernigan, 
    341 F.3d 1273
    , 1283 & n.8 (11th Cir. 2003) (“Under our
    caselaw, a party seeking to raise a claim or issue on appeal must plainly and
    prominently so indicate. Otherwise, the issue—even if properly preserved at
    trial—will be considered abandoned.”). Riechmann does argue in his reply brief
    that he can demonstrate cause and prejudice, but “[a]rguments raised for the first
    time in a reply brief are not properly before a reviewing court.” Herring v. Sec’y,
    Dep’t of Corr., 
    397 F.3d 1338
    , 1342 (11th Cir. 2005) (alteration in original)
    (quoting United States v. Coy, 
    19 F.3d 629
    , 632 n.7 (11th Cir. 1994)).15
    15
    Riechmann’s failure to properly raise his argument concerning cause and prejudice
    provides a sufficient basis for us to affirm the district court, but we note that, in any case, he
    would be unable to overcome the procedural default. While his appellate counsel’s failure to
    raise any Brady issue on appeal was likely sufficient cause for Riechmann’s failure to properly
    exhaust his guilt-phase Brady claim, he cannot demonstrate prejudice because, as we discuss
    below, the Brady claim ultimately is without merit.
    45
    Case: 18-10145   Date Filed: 10/07/2019   Page: 46 of 52
    Although we conclude that the district court properly determined that
    Riechmann’s Brady claim was procedurally defaulted, we will briefly address the
    substance of the underlying Brady claim, which we alternatively find lacks merit.
    2. Merits
    As with his ineffective assistance claim, Riechmann asserts that we should
    review de novo the merits of his underlying Brady claim, this time because the
    Florida Supreme Court invoked a procedural bar to reject his Brady claim, and the
    Brady claim therefore has not been “adjudicated on the merits” such that we must
    defer to that adjudication under AEDPA. See 28 U.S.C. § 2254(d); Conner v. Hall,
    
    645 F.3d 1277
    , 1292 (11th Cir. 2011) (stating that where a claim was “never
    adjudicated on the merits in state court because of the state court’s determination
    that . . . [the] claim was procedurally barred,” a federal habeas court “is not bound
    by AEDPA’s deferential standards in 28 U.S.C. § 2254(d) and federal court review
    is de novo”).
    Riechmann overlooks the fact that the Florida Supreme Court offered an
    alternative merits ruling on his Brady claim. After noting that the Brady claim was
    barred due to Riechmann’s failure to raise it on direct appeal, the Florida Supreme
    Court stated that “[n]otwithstanding [the procedural default], the [state 3.850] court
    found that even if disclosed, there was no reasonable probability that a different
    result would have occurred. We agree.” 
    Riechmann, 777 So. 2d at 363
    . In other
    46
    Case: 18-10145     Date Filed: 10/07/2019   Page: 47 of 52
    words, the Florida Supreme Court alternatively ruled on the merits of Riechmann’s
    Brady claim, concluding that the statements withheld by the state did not meet
    Brady’s materiality standard. This “alternative holding on the merits” constitutes
    “an ‘adjudication on the merits’ within the meaning of § 2254(d),” and we may not
    grant federal habeas relief unless the state unreasonably applied Brady. See
    Loggins v. Thomas, 
    654 F.3d 1204
    , 1219 (11th Cir. 2011); see also 28 U.S.C.
    § 2254(d)(1). Here, we cannot say that the Florida Supreme Court’s application of
    Brady was unreasonable given the facts before it.
    To establish a Brady violation, a defendant must show that
    (1) the government possessed favorable evidence to the defendant; (2)
    the defendant does not possess the evidence and could not obtain the
    evidence with any reasonable diligence; (3) the prosecution suppressed
    the favorable evidence; and (4) had the evidence been disclosed to the
    defendant, there is a reasonable probability that the outcome would
    have been different.
    United States v. Stein, 
    846 F.3d 1135
    , 1145–46 (11th Cir. 2017) (quoting United
    States v. Vallejo, 
    297 F.3d 1154
    , 1163 (11th Cir. 2002)). That last component, the
    materiality inquiry, should focus on “whether ‘the favorable evidence could
    reasonably be taken to put the whole case in such a different light as to undermine
    confidence in the verdict.’” 
    Id. at 290,
    119 S. Ct. at 1952 (quoting Kyles v.
    Whitley, 
    514 U.S. 419
    , 435, 
    115 S. Ct. 1555
    , 1566 (1995)). “The evidence rises to
    the level of materiality within the meaning of Brady when there is a reasonable
    probability that, had the suppressed evidence been disclosed, the result of the
    47
    Case: 18-10145     Date Filed: 10/07/2019    Page: 48 of 52
    proceeding would have been different.” Rimmer v. Sec’y, Fla. Dep’t of Corr., 
    876 F.3d 1039
    , 1054 (11th Cir. 2017). In making this determination, we must consider
    the “totality of the circumstances” and “‘evaluat[e]’ the withheld evidence ‘in the
    context of the entire record.’” 
    Id. (alteration in
    original) (internal quotation marks
    omitted) (quoting Turner v. United States, 582 U.S. ___, 
    137 S. Ct. 1885
    , 1893
    (2017)).
    Before delving into the analysis of Riechmann’s Brady claim, we more
    clearly identify the alleged Brady material under consideration here. It is
    somewhat unclear from the state court record and the parties’ briefs on appeal
    whether Riechmann’s Brady claim is based on the state’s failure to disclose the
    existence of all the witnesses identified and interviewed by German police in
    addition to the actual statements those witnesses gave. To the extent Riechmann
    claims the list of witnesses’ names is itself Brady material, he cannot reasonably
    claim that he could not locate those witnesses on his own. See 
    Stein, 846 F.3d at 1146
    (finding no Brady violation where the defendant can “locate [the evidence]
    with reasonable diligence”).
    For example, the four witnesses explicitly referenced in Riechmann’s brief
    and in his underlying state post-conviction motion—Doris Dessauer (or Röhn),
    Monika Seeger, Doris Rindelaub, and Dr. Horst Neumann—all were on the
    handwritten list of people in Germany to contact that Riechmann gave his defense
    48
    Case: 18-10145     Date Filed: 10/07/2019   Page: 49 of 52
    counsel prior to trial. Moreover, testimony at the evidentiary hearing indicates that
    defense counsel was in possession of the list itself pretrial, and was merely seeking
    the disclosure of the statements and reports from German police that the state had
    in its possession. Accordingly, we limit our analysis here to the materiality of the
    statements themselves, along with the other documentary evidence referenced in
    Riechmann’s Rule 3.850 motion and presented to the state 3.850 court at the
    evidentiary hearing.
    Moving on to the substance of Riechmann’s Brady claim, we will assume
    that Riechmann has satisfied Brady’s first two requirements. See 
    Strickler, 527 U.S. at 281
    –82, 119 S. Ct. at 1948. Our concern, then, is whether the withheld
    evidence was “material”—that is, whether “there is a reasonable probability that,
    had the suppressed evidence been disclosed, the result of the proceeding would
    have been different.” See 
    Rimmer, 876 F.3d at 1054
    .
    As to the statements themselves, Riechmann has only ever referenced the
    specific contents of four. Two of the statements came from Riechmann’s former
    girlfriends (Doris Dessauer and Doris Rindelaub), one came from his former
    landlady (Monika Seeger), and the last came from a friend who took care of his
    dogs (Dr. Neumann).
    Assuming the statements would have been admissible under Florida law, the
    Florida Supreme Court’s conclusion that the statements would likely not have
    49
    Case: 18-10145    Date Filed: 10/07/2019   Page: 50 of 52
    affected the outcome at trial is not unreasonable. Like the would-be testimony we
    discussed above in evaluating Riechmann’s ineffective assistance claim, the
    undisclosed statements would have undermined mainly the state’s evidence of
    motive, and only to a limited degree.
    Two of the witnesses whose statements were not disclosed—Doris Dessauer
    and Doris Rindelaub—were former girlfriends of Riechmann who had never even
    met Kischnick and had no idea what went on in their relationship. Indeed, neither
    woman had been in contact with Riechmann since their respective relationships
    with him ended, many years prior to the murder. Riechmann’s landlady, Monika
    Seeger, had very little contact with Kischnick and acknowledged that she and her
    family did not have a close relationship with the couple.
    The fourth statement came from Dr. Neumann, whose statement appears to
    have exclusively concerned his impressions of Riechmann’s financial situation.
    But his impressions were primarily based on how much Riechmann paid Dr.
    Neumann for taking care of his dogs and on the fact that Riechmann had recently
    won 40,000 German marks in the lottery. Notably, the mere fact that Riechmann
    won the lottery obviously was not information unknown to the defense at the time
    of trial. See 
    Stein, 846 F.3d at 1146
    . In any case, all of these statements come
    nowhere close to undermining the state’s powerful evidence of Riechmann’s
    motive to kill Kischnick. Simply put, it was not unreasonable for the Florida
    50
    Case: 18-10145     Date Filed: 10/07/2019   Page: 51 of 52
    Supreme Court to conclude that, in the context of the entire record, there was no
    reasonable probability of a different outcome. See 
    Rimmer, 876 F.3d at 1054
    .
    As for the remaining withheld evidence, Riechmann focuses particularly on
    a letter, purportedly from Kischnick’s employer, dated October 25, 1985, which he
    claims would have undermined the state’s theory that Riechmann would have been
    upset that Kischnick was quitting prostitution, as it showed she had an alternate
    source of income. Riechmann greatly overstates the value of this letter, assuming
    he has accurately described its contents. The fact that Kischnick had other sources
    of income does not preclude her having been a prostitute, nor does it flatly
    contradict any testimony about the amount of money she made as a prostitute.
    Further, Riechmann himself acknowledged during his testimony that Kischnick
    had worked as a prostitute at various points in time. Accordingly, the mere
    existence of some alternative source of income would hardly have undercut the
    state’s theory that Riechmann was upset by Kischnick’s desire to give up her
    lucrative job as a prostitute.
    For all these reasons, the Florida Supreme Court’s decision denying
    Riechmann’s Brady claim is not based on an unreasonable determination of the
    facts and is not contrary to, or an unreasonable application of, clearly established
    federal law, and we therefore defer to that decision.

    V. CONCLUSION
    For the foregoing reasons, we affirm the district court’s denial of
    Riechmann’s § 2254 petition.
    AFFIRMED.
