    GRUENDER, Circuit Judge.
    Wesley Ira Purkey appeals the denial of his motion to vacate, set aside, or
    correct his sentence under 
    28 U.S.C. § 2255
    . We granted a certificate of appealability
    to review whether Purkey received effective assistance of counsel during the penalty
    phase of the trial and whether the district court1 abused its discretion by denying relief
    without conducting an evidentiary hearing. We conclude that Purkey’s proffered
    evidence, taken as true, fails to establish that his trial counsel’s allegedly deficient
    performance was prejudicial to Purkey. Therefore, we affirm.
    I.
    In November 2003, a federal jury convicted Purkey of the interstate kidnap,
    rape, and murder of sixteen-year-old Jennifer Long. During the penalty phase of the
    trial, the jury heard evidence on six statutory aggravating factors, four non-statutory
    aggravating factors, and twenty-seven mitigating factors. The jury found the
    existence of all six statutory aggravating factors and three of the four non-statutory
    aggravating factors. The verdict form also contained spaces to record the number of
    jurors who found the existence of each mitigating factor presented by Purkey. The
    jury left each of those spaces blank. The jury determined that Purkey should be
    sentenced to death. We affirmed Purkey’s conviction and sentence on direct appeal.
    See United States v. Purkey, 
    428 F.3d 738
     (8th Cir. 2005), cert. denied, 
    549 U.S. 975
    (2006).
    Purkey then filed a motion to vacate, set aside, or correct his sentence pursuant
    to 
    28 U.S.C. § 2255
     and sought an evidentiary hearing. As relevant to this appeal,
    Purkey argued that his death sentence should be set aside because he did not receive
    effective assistance of counsel during the penalty phase of his trial, as required by the
    Sixth Amendment. With his motion, Purkey submitted a proffer of “new” mitigating
    evidence including affidavits from several family members, friends, and expert
    witnesses who testified at trial. Purkey claims that his trial counsel, Frederick
    Duchardt, failed to perform consistent with objective standards of reasonableness

    Court for the Western District of Missouri.

    because he failed to adequately investigate and prepare these witnesses. Additionally,
    Purkey submitted affidavits from several potential witnesses whom Duchardt never
    contacted during his mitigation investigation or whom Duchardt decided not to call
    as witnesses. Purkey argues that Duchardt’s performance also fell below an objective
    standard of reasonableness because he failed to call these witnesses during the
    penalty phase. Before replying to Purkey’s motion, the Government requested an
    order from the district court compelling Duchardt to provide an affidavit responding
    to Purkey’s claims of ineffective assistance. Duchardt prepared a 117-page affidavit,
    which the Government filed with its response to Purkey’s § 2255 motion. Duchardt’s
    affidavit contested many of the facts alleged in the affidavits attached to Purkey’s
    § 2255 motion and provided strategic reasons for not presenting some of the proffered
    evidence—all challenging Purkey’s claim that Duchardt’s performance fell below an
    objective standard of reasonableness.
    The district court denied Purkey’s § 2255 motion, determining that Duchardt’s
    performance did not fall below an objective standard of reasonableness. The district
    court alternatively concluded that, even assuming Duchardt’s representation did fall
    below an objective standard of reasonableness, Purkey’s proffered evidence did not
    support a finding of prejudice as required for relief under Strickland v. Washington,
    
    466 U.S. 668
     (1984). The district court also denied Purkey’s request for an
    evidentiary hearing, concluding that the proffered new evidence, taken as true,
    provided no basis for finding prejudice. See Machibroda v. United States, 
    368 U.S. 487
    , 496 (1962) (remanding for an evidentiary hearing because the petitioner would
    have been entitled to relief if the allegations in his § 2255 motion were true, even if
    the allegations were improbable).
    After the district court denied Purkey’s motion for a certificate of appealability
    (“COA”), Purkey requested a COA from this court. See 
    28 U.S.C. § 2253
    (c)(1)(B).
    We granted a COA on the issue of whether Duchardt’s performance during the
    penalty phase constituted ineffective assistance of counsel under the Sixth
    -3-
    Amendment. The COA allows Purkey to challenge three aspects of Duchardt’s
    performance in this proceeding: (1) his alleged failure to adequately prepare and
    present the testimony of three expert witnesses, (2) his alleged failure to adequately
    investigate and prepare two mitigating witnesses, which resulted in their testimony
    being more prejudicial than beneficial, and (3) his alleged failure to adequately
    investigate and present other mitigating evidence. We also granted a COA to
    determine whether the district court abused its discretion in denying Purkey’s request
    for an evidentiary hearing.

    “To establish ineffective assistance of counsel, [Purkey] must show that his
    counsel’s performance was deficient, and that he suffered prejudice as a result.” Paul
    v. United States, 
    534 F.3d 832
    , 836 (8th Cir. 2008) (citing Strickland, 
    466 U.S. at 687
    ). Purkey must establish prejudice by showing “a reasonable probability that, but
    for counsel’s unprofessional errors, the result of the proceeding would have been
    different.” Wong v. Belmontes, 
    558 U.S. 15
    , 19 (2009) (quoting Strickland, 
    466 U.S. at 694

    in the outcome.” Cullen v. Pinholster, 563 U.S. ---,

    , 1403 (2011)
    (quoting Strickland, 
    466 U.S. at 694
    ). “That showing requires [Purkey] to establish
    ‘a reasonable probability that a competent attorney, aware of [the available mitigating
    evidence], would have introduced it at sentencing,’ and ‘that had the jury been
    confronted with this . . . mitigating evidence, there is a reasonable probability that it
    would have returned with a different sentence.” Wong

    , 792 (2011)).

    During the penalty phase, Duchardt presented a lengthy and detailed mitigation
    case on behalf of Purkey, with testimony from eighteen witnesses spanning more than
    two days. The witnesses included Purkey’s brother, daughter, and aunt, as well as
    inmates and religious counselors with whom Purkey had developed relationships
    while in prison. Each family member testified that, as a child, Purkey suffered
    significant physical and emotional abuse at the hands of his parents. The evidence
    established that Purkey’s father was an alcoholic who repeatedly assaulted both
    Purkey and his brother and who eventually committed suicide. His mother, also an
    alcoholic, humiliated Purkey for stuttering, once throwing a drink in his face while
    he was having trouble speaking. Purkey’s brother, Gary Hamilton, was sexually
    abused by their mother beginning at age eleven or twelve. Hamilton testified that she
    forced him to have sex with her in the bathroom on numerous occasions, though he
    did not know whether their mother also abused Purkey in this manner because the two
    never discussed it.
    A religious counselor testified that Purkey was eager to leave his past behind,
    which Purkey had demonstrated by renewing his Christian commitments and
    expressing remorse for his crimes. Duchardt also elicited evidence that Purkey filed
    a request with the Bureau of Prisons to have his Aryan Brotherhood tattoos removed
    and attempted to cover up the tattoos on his own using flesh-toned ink. Family,
    friends, and fellow inmates alike testified that Purkey was a good friend, and that, if
    he were granted a life sentence rather than death, it would enrich their lives and the
    lives of his fellow prisoners.
    Duchardt also presented testimony from various prison officials and mental
    health experts. Perhaps the most important evidence Duchardt presented came from
    two of Purkey’s expert witnesses, Dr. Stephen Peterson and Dr. Mark Cunningham,
    who both testified in detail about the sexual abuse that Purkey suffered as a child. Dr.
    Peterson testified that Purkey’s mother, Velma, sexually assaulted Purkey between
    ages six and fourteen, teaching him to “sexually stimulate her anally and orally and
    -5-
    . . . washing him in way[s] that were sexualized.” Purkey also witnessed his mother
    “being sexually involved with many of her paramours” after his father left the family
    household. When Purkey was about fourteen years old, his father began offering to
    pay for prostitutes for Purkey, “encourag[ing] him to be sexually active well beyond
    his years and emotional development.” According to Dr. Peterson, these experiences
    rendered Purkey unable to engage normally with anyone in a sexual way and caused
    him to seek sexual gratification in a “scripted and controlled” manner.
    In addition to interviewing Purkey, Dr. Peterson reviewed Purkey’s medical
    and mental health records to corroborate Purkey’s account of his past. He located a
    Kansas State Reception Diagnostic Center report from 1982 that described Purkey as
    “having a serious personality disorder centered on psychosexual problems of
    identification,” a diagnosis consistent with reports of Purkey’s childhood sexual
    abuse. Dr. Peterson also found within Purkey’s records a statement from his aunt,
    which corroborated Purkey’s claims of childhood abuse.
    Dr. Cunningham gave similar testimony. He discussed in detail the sexual acts
    that Velma forced Purkey to perform on her. She had Purkey “rub[] lotion on her . . .
    stimulat[e] her with a hair brush, penetrat[e] her with a hair brush, [engage in] oral
    genital sexual exchanges, and ultimately hav[e] intercourse with her.” Dr.
    Cunningham also confirmed that Purkey witnessed his mother having sex with other
    men in their home. He further testified that it was not unusual for a male to conceal
    childhood sexual abuse, noting that Purkey’s records revealed symptoms of sexual
    abuse when he was as young as fifteen. Duchardt also called a third expert witness,
    clinical psychologist Dr. Bruce Leeson, who testified that Purkey had significant
    frontal lobe damage that affected his ability to control impulsive behavior. He also
    testified that Purkey had a below-average IQ of 90.
    For more than two days, the jury listened to witnesses testify that Purkey is a
    positive influence in their lives and that society would be better off if he were to
    -6-
    receive a life sentence rather than a death sentence. The jury also heard, in significant
    detail, that Purkey’s parents abused him sexually throughout his childhood, causing
    him to develop abnormal sexual tendencies. Yet in his § 2255 motion to vacate,
    Purkey argues that Duchardt failed to present evidence of his childhood sexual abuse
    and his positive character traits. He also argues that Duchardt’s performance fell
    short when preparing several mitigation witnesses for their testimony.
    In Purkey’s proffer of new evidence submitted with his § 2255 motion, several
    witnesses who testified during the penalty phase complain that, although Duchardt
    contacted them during his mitigation investigation, his investigative techniques were
    ineffective for various reasons. Hamilton, for example, claims that he withheld
    material evidence from Duchardt during the mitigation investigation because
    Duchardt’s son was present during their interview. Purkey claims the evidence
    Hamilton withheld was pertinent to his defense. In his affidavit, Hamilton recalled
    an incident in which the boys’ father slammed Velma’s arm in a door repeatedly until
    it broke, indicating that he would have told the jury about the incident if Duchardt’s
    investigation had been more thorough. Purkey’s daughter, Angie Genail, criticizes
    Duchardt’s investigation because he first visited her home for an interview on the day
    of her wedding and because he failed to follow up when she asked to reschedule.
    Duchardt only contacted her shortly before trial, never discussing his plan for her
    testimony, and Genail felt unprepared to testify as a result. If better prepared, Genail
    claims she would have testified about the many poems, stories, and songs that Purkey
    has written for her. Marguerite Hotchkiss, Purkey’s aunt, felt similarly unprepared
    and further claims that the circumstances of her testimony, which Duchardt conducted
    via teleconference, hampered her testimony. Had Duchardt adequately prepared her,
    Hotchkiss now avers that she would have testified that Purkey’s childhood home was
    unkempt and constantly reeked of liquor and cigarettes from his parents’ drinking and
    smoking and that Velma was a “party girl” with poor parenting skills.
    -7-
    The non-testifying individuals identified in Purkey’s proffer of new evidence
    complain that Duchardt’s investigation was defective because he either never
    contacted them or chose not to have them testify. Purkey’s cousin and two of his
    childhood friends reiterate that Purkey grew up in an abusive home and claim that he
    is nevertheless a positive influence in their lives. A volunteer prison minister avers
    that Purkey never caused problems with other inmates and that his “family is still his
    number one concern.” Two family friends, Floyd Bose and Floyd’s daughter Dion
    Lieker, commended Purkey for his role in solving the murder of Floyd’s son (Dion’s
    brother) in prison. Bose and Lieker each went on to develop relationships with
    Purkey, both noting that Purkey was very sorry for his crimes. Lieker especially
    found Purkey to be compassionate but also unstable because his father “beat the
    daylights” out of him and because his mother forced him to have sex with her. Dr.
    Rex Newton, a prison psychologist who knew Purkey in 1987, believed, based on
    Purkey’s behavior in prison, that he had been sexually abused as a child and noted
    that he would have testified and discussed corroborating evidence if Duchardt had
    asked him to testify.
    Purkey also argues that Duchardt failed to adequately prepare and present the
    testimony of Dr. Peterson, Dr. Cunningham, and Dr. Leeson. He claims Duchardt
    should have allowed Dr. Peterson and Dr. Cunningham to testify about Purkey’s
    sexual abuse in greater detail, that Dr. Peterson was not properly prepared to testify
    because he was aware of additional medical records that corroborated Purkey’s claims
    of childhood abuse and failed to mention them during cross-examination, that
    Duchardt should have allowed Dr. Cunningham to use a PowerPoint presentation that
    he prepared to aid his testimony, and that Duchardt should have better prepared Dr.
    Leeson to withstand the Government’s cross-examination.
    Finally, Purkey argues that Duchardt failed to adequately prepare Mark Russell
    and Dr. William Grant, resulting in their testimony being more prejudicial than
    beneficial. Russell, a correctional counselor at the Bureau of Prisons, testified that
    -8-
    Purkey was housed in a special cell block while awaiting trial and spent at least
    twenty-three hours per day in his cell. Dr. Grant, a Bureau of Prisons psychiatrist,
    testified about the medications he prescribed to treat Purkey’s anxiety while awaiting
    trial. Purkey claims Dr. Grant’s testimony was ultimately prejudicial because he
    characterized Purkey’s “anxiety” as “attitude, belligeren[ce], irritab[ility]” in response
    to a question on cross-examination. Purkey argues that Russell’s testimony became
    prejudicial because he revealed on cross-examination that Purkey was housed in a
    special unit due to his history of behavioral problems.
    All of Purkey’s proffered evidence does nothing to establish prejudice as
    required by Strickland because it is entirely cumulative. See Paul, 
    534 F.3d at 843
    (holding that the existence of additional but cumulative mitigating evidence “[was]
    insufficient to undermine confidence in the jury’s verdict in the penalty phase”).
    During the penalty phase, Duchardt presented two days of testimony to support the
    argument that Purkey would provide a net benefit to society if he were to serve a life
    sentence. The new evidence about Purkey’s positive influence on others adds nothing
    of substance. Duchardt also presented extensive, detailed evidence from multiple
    sources about the sexual abuse Purkey suffered as a child. Dr. Peterson testified that
    Purkey’s behavior as early as 1982 suggested a history of childhood sexual abuse.
    Notably, the Kansas State Reception Diagnostic Center report that Dr. Peterson
    discussed is the same corroborating evidence that Purkey now argues Dr. Newton
    could have presented. Purkey’s isolated examples of “prejudicial” testimony
    resulting from Duchardt’s alleged failure to prepare mitigation witnesses comprised
    only a tiny portion of Purkey’s case in mitigation. As the newly proffered evidence
    is entirely cumulative and the examples of “prejudicial” mitigation testimony are
    insignificant compared to the rest of the extensive case in mitigation, we conclude
    that Purkey suffered no prejudice, even assuming Duchardt’s representation was
    -9-
    constitutionally defective.2 See Hanegan v. Miller, 
    663 F.3d 349
    , 354-56 (8th Cir.
    2011), cert. denied, 566 U.S. ---, 
    132 S. Ct. 2393
     (2012) (assuming counsel’s
    performance fell below an objective standard of reasonableness but denying habeas
    relief because petitioner failed to establish prejudice); see also Cullen, 
    131 S. Ct. at 1409
     (finding no prejudice where “new” evidence largely duplicated the mitigation
    evidence presented at trial); Wong, 
    558 U.S. at 22-23
     (concluding that additional
    evidence of the defendant’s “humanizing” features would not have affected the
    sentencing jury’s decision); Bobby v. Van Hook, 
    558 U.S. 4
    , 12 (2009) (finding no
    prejudice where “[n]either the Court of Appeals nor [the petitioner] has shown why
    the minor additional details the [fact finder] did not hear would have made any
    difference”).
    Even assuming for the purposes of argument that Purkey’s filings did present
    new material evidence, we must assess prejudice by “reweigh[ing] the evidence in
    aggravation against the totality of available mitigating evidence” to determine
    whether “the result of the proceeding would have been different.” Wiggins, 
    539 U.S. at 534
     (citation omitted). The underlying crime in this case is particularly gruesome,
    and the Government presented substantial incriminating evidence during the guilt
    phase, which created context for the aggravation case it later presented during the
    2
    Purkey spends a considerable portion of his brief arguing that the district court
    improperly denied his motion to strike Duchardt’s 117-page affidavit. Purkey also
    argues that the Duchardt affidavit made an evidentiary hearing necessary because the
    affidavit contradicts some aspects of his proffered new evidence and asserts strategic
    choices that are not credible. The Government moves to strike this portion of
    Purkey’s brief, arguing that Purkey’s request to strike the affidavit is outside the
    scope of the COA. Purkey counters that the question is intertwined with the issues
    identified in the COA. Because we conclude that Purkey fails to establish prejudice
    without reaching the only matter addressed in the affidavit—whether Duchardt’s
    performance fell below an objective standard of reasonableness—we need not
    consider any of the contents of Duchardt’s affidavit. As a result, we deny as moot the
    Government’s motion to strike.
    -10-
    penalty phase. According to Purkey’s confession to the FBI, which was largely
    confirmed by his own testimony during the guilt phase, Purkey drove to Kansas City,
    Missouri, from his home in Lansing, Kansas, on January 22, 1998, for a job interview
    with a plumbing company. After the interview, Purkey smoked half a rock of crack
    cocaine and began driving down the street when he passed sixteen-year-old Jennifer
    Long, who was walking on the sidewalk. He pulled over to ask Jennifer if she wanted
    to “party,” then took her to a liquor store to buy her gin and orange juice. After
    buying her the gin, Purkey told Jennifer he needed to go back to his home in Kansas.
    She asked to be let out of his truck. Instead, Purkey reached into the glove box,
    grabbed a boning knife, and placed it under his thigh, making it clear that he would
    not let her go.
    When they arrived at his home, Purkey took Jennifer into a room in his
    basement. Holding a knife, he ordered her to take her clothes off and lie down on the
    floor, where he raped her. After Purkey finished raping her, Jennifer told him that she
    had been a virgin. He then grew fearful, and as Jennifer tried to escape his house, he
    grabbed her leg and forced her to the ground. The two briefly struggled before
    Purkey became enraged and repeatedly stabbed Jennifer in the chest, neck, and face
    with the boning knife, eventually breaking its blade inside her body. When he
    confessed, he told FBI Agent Dirk Tarpley, “it’s not like in the movies. They don’t
    die right away. It took her a little time to die.” Purkey then stuffed Jennifer’s body
    into a toolbox, cleaned up the surrounding area, and spent several hours drinking at
    a bar before driving to Sears to purchase an electric chainsaw. Over the next few
    days, Purkey used the chainsaw to dismember Jennifer’s body while it was lying
    inside the box. Several times, Purkey had to stop and clean the chainsaw to continue
    cutting the body because it had become clogged with her remains. At one point, he
    examined Jennifer’s heart, observing two stab wounds. Once he finished
    dismembering Jennifer’s body, he divided her body parts among several plastic bags
    and added in leaves and debris from his back yard. Purkey enlisted his stepchildren
    to help him clean the basement with bleach. He then purchased several cords of
    -11-
    wood and began to burn the bags in his fireplace one by one while his wife and
    stepchildren were away at work and school. To keep the fire hot, he added diesel
    fuel. Despite these efforts, Jennifer’s bones did not burn completely. He crushed the
    remaining bone fragments with his hands. When he finished burning Jennifer’s body,
    Purkey collected her remains from the fireplace with a wet-dry vacuum and refilled
    the garbage bags. He then dumped the remains into a septic pond in Clearwater,
    Kansas.
    No one knew about Jennifer’s murder until Purkey himself contacted a Kansas
    City, Kansas police officer while incarcerated in a Kansas state prison for the
    unrelated murder of 80-year-old Mary Ruth Bales. The jury heard the details of
    Bales’s murder during the penalty phase. Nine months after raping and murdering
    Jennifer Long, Purkey was employed by a plumbing company. He met Bales when
    he responded to a service call at her home during the evening of October 26, 1998.
    Purkey told Bales that his employer charged a great deal for the particular job she
    needed, and he offered to return later to do the work under the table if she would pay
    him $70 up front. She paid, and Purkey left, using Bales’s money to hire a prostitute
    and buy several rocks of crack cocaine the next morning. Purkey and the prostitute
    proceeded to a motel room for several hours, where they had sex and smoked the
    crack cocaine before driving together to Bales’s house. Telling the prostitute that
    someone who lived in the home owed him money, Purkey went inside with a toolbox
    from his truck and bludgeoned Bales to death in her bedroom with a claw hammer.
    Investigators determined that Bales, who had suffered from polio and walked with a
    cane, died from blunt force trauma resulting from repeated strikes to her skull with
    the claw side of the hammer. Bales also suffered from defensive wounds on both
    hands.
    After murdering Bales, Purkey stayed at Bales’s house for several hours with
    the prostitute, injecting drugs, smoking crack cocaine, and eating food from Bales’s
    kitchen. The next day, Purkey returned to the house with two gallons of gasoline,
    -12-
    intending to burn it down. He was arrested after a neighbor saw him in Bales’s back
    yard and reported him to the police. Purkey pled guilty to murdering Bales and faced
    a life sentence in the Kansas penitentiary. In a misguided attempt to avoid serving
    a life sentence in state prison for murdering Bales, Purkey contacted authorities about
    the interstate abduction, rape, and murder of Jennifer Long, hoping to serve his life
    sentence in the relatively more comfortable surroundings of a federal penitentiary.
    In addition to the details of Bales’s murder and the other evidence related to
    the circumstances of Purkey’s confession, the Government introduced evidence of
    Purkey’s thirteen prior felony convictions, including: first-degree burglary in 1970;
    robbery and theft in 1976; aggravated escape from custody in 1978; and multiple
    counts of aggravated robbery, kidnaping, aggravated battery, and firearms violations
    in 1981. The jury also heard from several additional witnesses during the penalty
    phase. Gregg Carlberg testified that in 1980 Purkey and his friend kidnaped
    Carlberg, drove him into the woods, shot him in the head, and left him for dead. Gary
    Hatfield, a man who was incarcerated with Purkey in Oregon, testified that Purkey
    raped him at knife-point in a prison kitchen. A prison gang expert explained that
    Purkey’s “Aryan Pride,” swastika, and Ku Klux Klan tattoos indicated his
    involvement with the Aryan Brotherhood. And finally, Jennifer Long’s family shared
    the impact of her death. Her father told the jury, “I can sit here for hours and tell you
    that he didn’t murder her that day, he murdered me”; her mother lamented, “I lost my
    house. . . . I lost my job. I lost my car. I lost my husband. I lost my will. I lost a lot
    of great things, but most of all I lost her.” After deliberating, the jury found nine
    aggravating factors beyond a reasonable doubt and determined that Purkey should be
    sentenced to death. See Purkey, 
    428 F.3d at 746
    .
    In light of the heinous abduction, rape, and murder of sixteen-year-old Jennifer
    Long and the similarly heinous bludgeoning murder of eighty-year-old Mary Ruth
    Bales, both committed by someone who also had been convicted of first-degree
    burglary, aggravated robbery, theft, aggravated escape from custody, aggravated
    -13-
    battery, and who also kidnaped and tried to kill an innocent bystander and raped a
    man in prison, we conclude that it is not substantially likely that the jury would have
    returned a different sentence had Purkey’s proffered evidence been presented to it.
    See Cullen, 
    131 S. Ct. at 1403
     (requiring a habeas petitioner to show a “‘substantial,’
    not just ‘conceivable,’ likelihood of a different result” to establish prejudice (quoting
    Harrington 
    131 S. Ct. at 792
    )). The aggravating evidence is too overwhelming and
    the “new” mitigating evidence too redundant for us to conclude that even “one juror
    would have struck a different balance.” See Wiggins, 
    539 U.S. at 537
    ; see also
    Williams v. Roper, 
    695 F.3d 825
    , 832-33 (8th Cir. 2012) (concluding that the state
    court reasonably determined that new evidence of the defendant’s childhood sexual
    abuse did not establish prejudice where the state presented overwhelming aggravation
    evidence); Paul, 
    534 F.3d at 840-42
     (affirming the denial of an inmate’s § 2255
    motion and holding that the inmate’s newly proffered evidence was largely
    cumulative and thereby failed to establish the reasonable probability of a different
    sentence).3
    Accordingly, we affirm the district court’s denial of Purkey’s motion to vacate,
    set aside, or correct his sentence.

    Purkey also asks us to reverse the district court because it relied on the
    arguably incomplete mitigating factors portion of the verdict form to conclude that
    Purkey failed to establish prejudice. See Purkey v. United States, 06-8001-CV-W-
    FJG, 
    2009 WL 3160774
    , at *5 (W.D. Mo. Sept. 29, 2009) (“[O]f the twenty-seven
    mitigating factors which were presented to the jury, no jurors voted for a single
    mitigating factor.”). However, we review the issue of prejudice de novo, Hamberg
    v. United States, 
    675 F.3d 1170
    , 1172 (8th Cir. 2012), and we have not relied on the
    fact that the jury did not record any findings with respect to the mitigating factors in
    reaching our conclusion that Purkey fails to establish prejudice. On direct appeal, we
    held that the jury is not required to identify the mitigating factors it may find to exist
    and that the district court did not err when it accepted the arguably incomplete form.
    See Purkey, 
    428 F.3d at 763
    .

    Purkey also argues that the district court abused its discretion by denying his
    request for an evidentiary hearing. No evidentiary hearing is required where “the
    motion and the files and records of the case conclusively show that the prisoner is
    entitled to no relief . . . .” 
    28 U.S.C. § 2255
    (b). We review the denial of a § 2255
    evidentiary hearing for an abuse of discretion, but this standard is “somewhat
    misleading . . . because review of the determination that no hearing was required
    obligates us to look behind that discretionary decision to the court’s rejection of the
    claim on its merits, which is a legal conclusion that we review de novo.” Noe v.
    United States, 
    601 F.3d 784
    , 792 (8th Cir. 2010) (quoting Saunders v. United States,
    
    236 F.3d 950
    , 952 (8th Cir. 2001)). Thus, when reviewing the denial of Purkey’s
    motion for an evidentiary hearing, we must review the district court’s conclusion that
    the evidence Purkey presented along with his § 2255 motion, taken as true, was
    insufficient to establish a violation of his Sixth Amendment right to effective
    assistance of counsel. As explained above, our de novo review of the record
    conclusively shows Purkey is unable to establish prejudice as required by Strickland.
    We therefore hold that the district court did not abuse its discretion by denying
    Purkey’s request for an evidentiary hearing. See Hill v. Lockhart, 
    474 U.S. 52
    , 60
    (1985) (“Because petitioner in this case failed to allege the kind of ‘prejudice’
    necessary to satisfy the second half of the Strickland v. Washington test, the District
    Court did not err in declining to hold a hearing on petitioner’s ineffective assistance
    of counsel claim.”).

    We also deny Purkey’s belated motion to proceed pro se, filed after the case
    was fully briefed.
