    Counsel for Appellee
    OPINION OF THE COURT
    AMBRO, Circuit Judge:
    Jack Foster Outten, Jr., was convicted by a Delaware jury
    2
    of, inter alia, first-degree murder and sentenced to death. His
    direct appeals and post-conviction claims in state court were
    unsuccessful. Outten then filed in federal court a 28 U.S.C.
    § 2254 petition for a writ of habeas corpus, which the United
    States District Court for the District of Delaware denied. We
    conclude that trial counsel’s failure to conduct a reasonable
    investigation of Outten’s background in anticipation of his
    capital sentencing violated his Sixth Amendment right to
    effective assistance of counsel. Thus, we reverse and remand
    this case for resentencing.
    I.     Factual and Procedural Background
    A.     The Murder of Willie Mannon
    We recite only briefly the pertinent facts of this case as
    set forth by the District Court, Outten v. Snyder, Civ. No. 98-
    785-SLR, 
    2004 U.S. Dist. LEXIS 5546
    (D. Del. Mar. 31, 2004)
    (Outten IV), and the Delaware Superior Court, State v. Outten,
    No. C.R.A. IN-92-01-1144, 
    1997 WL 855718
    (Del. Super. Ct.
    Dec. 22, 1997) (Outten II). (All city or town references are in
    Delaware.) Outten, his cousins Steven and Nelson Shelton, and
    Nelson’s girlfriend, Christina Gibbons, spent the afternoon of
    January 11, 1992, drinking beer at Nelson and Gibbons’s home
    in Newark. After consuming approximately one and one-half
    cases of beer, the four drove to Clemente’s Bus Stop, a local
    tavern located on Route 13 south of Wilmington.
    3
    After separating for a short time, Outten, the Sheltons,
    and Gibbons eventually reconvened and went to Hamill’s Pub
    in Elsmere, and then to Fat Boys Bar in New Castle. At Fat
    Boys Bar, the three men began playing pool while Gibbons sat
    at the bar counter alone. She began conversing and drinking
    with sixty-two year old Wilson “Willie” Mannon, who had
    arrived at the bar earlier that same day. Ultimately, Mannon left
    with Gibbons and the three men.
    Mannon’s body was discovered along a road in a deserted
    area of East Wilmington at approximately 11:00 a.m. on January
    12, 1992. He was found lying on his back with his legs crossed
    and the top of his head shattered. Mannon’s pockets were
    turned inside-out, and loose change, his empty wallet, and his
    identification cards were scattered nearby. A broken ballpeen
    hammer handle rested a few feet away from his body and the
    head of that hammer was located behind a nearby fence along
    the road.
    Nelson Shelton and Gibbons were stopped by New Castle
    County police later that morning. The officers sought to
    question Nelson on an unrelated charge. He was taken to police
    headquarters and found to be in possession of two gold rings
    that were Mannon’s. His winter jacket also appeared to be
    stained with blood.
    Gibbons accompanied Nelson to the police station.
    While there, she provided statements to New Castle County and
    4
    Wilmington law enforcement officers implicating Outten and
    Steven Shelton in the robbery and murder of Mannon. Gibbons
    recounted that she had been at a bar the previous night with
    Outten and the Shelton brothers, and that, at the end of the night,
    the four of them left in Nelson’s car with an “older man” named
    Willie. From the bar, they drove to a “boat yard,” where the
    older man was beaten with a hammer and an object she thought
    was a sink. According to Gibbons, Outten struck the man with
    the sink and Steven kicked him. She was adamant that Nelson,
    though present, was not involved. Gibbons also told police that
    the sink was discarded along Interstate 95 after the murder.
    The next day, January 13, 1992, Gibbons spoke about
    Mannon’s murder to her social worker, Sandra Nyce. The story
    she recounted to Nyce differed significantly from her prior
    statements to the police. Indeed, she implicated Outten and both
    Shelton brothers in the beating and murder, telling Nyce that all
    three men had taken turns hitting Mannon and that they had
    killed a “nice old man.”
    B.     The Trial Court Proceedings
    Acting quickly, on January 21, 1992, a Delaware grand
    jury indicted Outten and the Sheltons for Mannon’s death. They
    were charged with, inter alia, first-degree murder, first-degree
    conspiracy, first-degree robbery, and possession of a deadly
    weapon during the commission of a felony. The defendants
    were tried together in the Delaware Superior Court in New
    5
    Castle County in January–February 1993. Gibbons, who in
    addition to providing multiple contradictory accounts of the
    murder during the investigation gave conflicting testimony at
    trial, was the State’s principal witness.1 After deliberating for
    two days, the jury convicted the defendants of all offenses as
    charged.
    A penalty hearing was held on March 3–5, 1993.
    Counsel for both Outten and Steven Shelton made opening
    statements. One of Outten’s counsel—there were two 2 —told
    the jury its decision was simple: choose life or death. He also
    stated that he and his co-counsel were there “to beg for the life
    of [their] client.” Steven’s counsel, by contrast, stated, “My
    client has instructed me to advise you that we will not be
    begging for his life in this case.”
    1
    During her initial testimony, Gibbons implicated only Outten
    and Nelson Shelton in the murder of Mannon. She retook the
    stand, however, and conceded that her prior testimony had been
    false, and testified that all three defendants had participated in
    the beating and killing of Mannon. For a comprehensive
    account of Gibbons’s various statements to investigators and the
    jury, see Outten IV, 
    2004 U.S. Dist. LEXIS 5546
    , at *9–13.

    Outten was represented by the same two attorneys at trial and
    on direct appeal. Outten II, 
    1997 WL 855718
    , at *76 n.188. For
    the remainder of this opinion, any reference to Outten’s trial
    counsel means both attorneys unless the context requires
    otherwise.
    6
    The State then presented evidence of Outten’s past
    criminal history. That evidence included: a house burglary
    conviction; seven convictions for non-violent crimes including
    forgery, issuance of a bad check, misdemeanor theft, felony
    theft, and criminal impersonation; his family court record; and
    his probation violations.
    Thereafter, Outten presented his mitigation case to the
    3
    jury.       He called as witnesses his mother (Carol Outten), two
    3
    Nelson Shelton presented no evidence in mitigation. He was
    sentenced to death, waived all appeals and/or post-conviction
    remedies, and was executed on March 17, 1995. Steven
    Shelton, after extensive colloquies with the trial court, presented
    only limited evidence in mitigation. In allocution (here,
    speaking directly to the jury), Steven stated:
    Ladies and gentlemen of the jury, I stand before
    you not to plead for my life. I feel that’s wrong
    and improper and basically disrespectful to the
    victim’s family and to mine. The State has
    painted a picture, and that picture is not very
    pretty, pertaining to me and my co-defendants.
    And I would just like to present to the jury a
    different side or a different meaning to Steven
    Shelton. The State has pictured me as being a
    monster, as being a rapist, as being a violent
    individual, but as you heard from my family,
    that’s not so. The State only presents one side of
    7
    sisters (Robin Outten and Amanda Hart), brother (John Outten),
    friend (Ruperto Sanchez), and a former girlfriend and the
    mother of two of his children (Karen Julian).
    Outten’s mother testified first. She described Outten’s
    relationship with his father, Foster Outten, as his father was
    dying of cancer. Outten II, 
    1997 WL 855718
    , at *21.
    According to Mrs. Outten, Outten had stayed in his parents’
    home in order to care for his father for the last two years of his
    life. 
    Id. He continued
    to assist his father even when he was
    completely bed-ridden. 
    Id. Mrs. Outten
    depicted her husband
    as a “very strict” man who “punished [the] children as he saw
    fit.” 
    Id. She indicated
    that Outten had “started off in school
    okay but got into truancy trouble,” and only made it to the
    eleventh grade. 
    Id. Mrs. Outten
    also discussed her son’s
    criminal history, including his prior convictions for assault. On
    cross-examination, she confirmed that Outten had physically
    the picture. There’s two sides to every story.
    And the State just presents a negative side. The
    jury has found me guilty of these allegations, and
    now it’s the jury’s turn to render a verdict. And
    that verdict is either life in jail or death. Again,
    I’m not here to plead for my life, but just ask the
    jury to be fair in their decisions. That’s all I have
    to say.
    Outten II, 
    1997 WL 855718
    , at *25–26.
    8
    attacked his sister Amanda. 
    Id. Outten’s sister
    Robin testified next. She also explained
    that Outten had cared for his father toward the end of his life.
    
    Id. She stated
    that “Outten was very upset by his father’s death
    and cried like she had never seen before.” 
    Id. Robin told
    the
    jury that Outten had a child with Karen Julian in 1991, but the
    baby had died shortly after birth. 
    Id. “[T]his too,”
    she said,
    “was most upsetting to Outten.” 
    Id. On cross-examination,
    Robin admitted that she had accrued “theft and misdemeanor
    convictions,” and that those crimes “also involv[ed] Outten.”
    
    Id. Ruperto Sanchez,
    a family friend, testified that he
    observed “Outten being upset when his baby died.” 
    Id. He also
    “mentioned the good relationship Outten had with his father.”
    
    Id. On cross-examination,
    Sanchez stated that he had been
    convicted in 1991 of a misdemeanor offense involving both
    Robin and Outten. 
    Id. Amanda Hart,
    another of Outten’s sisters, then testified.
    “She described . . . [a physical altercation that occurred] in 1989
    between Outten and [Karen] Julian.” 
    Id. According to
    Hart,
    Outten punched her in the eye when she attempted to intercede.
    
    Id. An affidavit
    of probable cause signed by Hart and
    introduced by the prosecution on cross-examination indicated
    that Outten had caused damage to her residence as well. 
    Id. Hart stated
    that there were times that she and Outten had lived
    9
    together. During those times, Outten was “helpful to her and
    others,” and treated her infant children well. 
    Id. at *22.
    She
    also discussed “how Outten took care of his father in the last
    years of his illness.” 
    Id. Karen Julian
    then took the stand. She and Outten had
    lived together for about four-and-a-half years prior to his arrest
    for the underlying offense. 
    Id. According to
    Julian, Outten had
    been working as a roofer, but had been laid off four to six weeks
    before the murder. 
    Id. She also
    “told the jury that Outten had
    not completed an alcoholic rehabilitation program because he
    would not give the names of others who had broken some
    rules.” 
    Id. Outten’s final
    witness was his older brother, John. He
    testified that “[t]heir father became blind in one eye and suffered
    a speech impediment as a result of [a] mugging” that occurred
    in 1974. 
    Id. John also
    told the jury that “Outten seemed to
    suffer the worst from their father’s frustration” with his
    impaired condition. 
    Id. It was
    John’s opinion that his brother’s
    relationship with their father “caused Outten to start stealing.”
    
    Id. Outten also
    spoke directly to the jury in allocution. He
    described his family as “close-knit,” but did state that he had
    been “semi-abused.” 
    Id. According to
    Outten, “his father
    ‘chastened’ him, making him run away.” 
    Id. Outten also
    reviewed his extensive criminal record, characterizing himself
    10
    as “mischievous.” 
    Id. He “pointed
    out to the jury that his
    convictions were for non-violent offenses, such as forgery, theft
    and criminal mischief.” 
    Id. Outten described
    himself as a
    “kleptomaniac” and admitted that he drank alcohol and took
    drugs. 
    Id. He explained
    that he “had a regular roofing job and
    started his own company,” but “[h]e stole . . . to buy tools
    needed for [his] work.” 
    Id. In closing,
    Outten told the jury that
    he was caring, sharing, loving and honest—not cold, calculating,
    ruthless or heartless. 
    Id. at *23.
    It was his opinion that “his
    good qualities outweighed the bad.” 
    Id. Beyond the
    above recounted testimony, trial counsel did
    not introduce at the sentencing hearing any additional mitigating
    evidence or documents (i.e., child protective service records,
    mental health records, school records). Nor is there any
    indication that Outten’s extensive social or psychiatric history
    was presented comprehensively by an expert, family member or
    counsel.
    In his closing, the prosecutor remarked:
    Another thing that judges, for me, the importance
    of what you do and what this all means is the
    remorse that has been shown in this case in the
    words of Jack Outten in allocution and Steven
    Shelton in allocution. And they told you or paid
    lip service that they had concerns for the families
    of the victim, but what did you hear about their
    11
    remorse for their acts? What did you hear about
    that concern for the families of the victim whose
    life was taken innocently, without any wrong that
    he caused any of these individuals?
    
    Id. at *45.
    Outten’s counsel did not object to these comments.
    Consistent with the state death penalty statute in effect at
    the time of the sentencing hearing, 
    11 Del. C
    . § 4209, the jury
    unanimously found beyond a reasonable doubt the existence of
    three aggravating factors: (1) the murder was committed during
    a robbery, 
    id. § 4209(e)(1)(j),
    (2) a motive for the murder was
    pecuniary gain,4 
    id. § 4209(e)(1)(o),
    and (3) the victim was over
    sixty-two years old, 
    id. § 4209(e)(1)(r).
    Moreover, by a vote of
    seven to five, the jury found by a preponderance of the evidence
    that the aggravating circumstances outweighed the mitigating
    circumstances presented by Outten. As a result, the jury
    recommended a sentence of death.
    In sentencing Outten, the trial judge acknowledged that
    he had proposed four factors in mitigation: Outten’s age, his
    lack of violent felonies, his family status, and his amenability to
    lesser sanctions than death. According to the judge, Outten’s
    relative youth (he was thirty) was diminished by his extensive
    4
    Interestingly, Mannon had no money with him at the time of
    the murder but he was wearing the rings found in Nelson
    Shelton’s possession on the morning of January 12, 2003.
    12
    appearances in the criminal justice system. The judge also
    concluded that Outten’s long-standing substance abuse problem
    and the evidence of alcohol consumption on the evening of the
    murder were diminished as mitigation by his failure to complete
    substance abuse programs. The judge did recognize that the
    father’s disability, alcohol abuse, and strictness had a negative
    effect on Outten. Ultimately, however, the judge independently
    concluded that the aggravating circumstances outweighed the
    mitigating circumstances and, on April 30, 1993, sentenced
    Outten to death for the murder of Mannon. (The jury also
    found, by a vote of eight to four, that aggravating circumstances
    outweighed the mitigating circumstances presented by Steven
    Shelton. The judge independently agreed with the jury’s
    recommendation, sentencing him to death as well.)
    C.     Outten’s Direct Automatic Appeal
    Pursuant to 
    11 Del. C
    . § 4209(g), an automatic appeal
    was taken to the Delaware Supreme Court. On appeal, Outten
    argued that (1) the Superior Court erred by refusing to grant a
    severance of his trial from that of his co-defendants; (2) the
    State’s use of a peremptory challenge to strike an African-
    American juror from the jury violated Batson v. Kentucky, 
    476 U.S. 79
    (1986); and (3) the Superior Court erred by not allowing
    him to introduce extrinsic evidence in support of the credibility
    of one of his witnesses at trial. Outten v. State, 
    650 A.2d 1291
    ,
    1293 (Del. 1994) (Outten I). The Delaware Supreme Court
    rejected each of Outten’s claims and, accordingly, affirmed his
    13
    conviction and sentence. 
    Id. at 1298–1300,
    1301–02.
    D.     Outten’s State Post-Conviction Proceedings
    Outten next filed an amended motion for post-conviction
    relief in the Delaware Superior Court, arguing that his counsel
    was ineffective during both the guilt and penalty phases of his
    trial proceedings. He specifically contended that counsel erred
    by failing to (1) conduct an adequate pre-trial investigation, (2)
    move for severance of his guilt phase from that of his co-
    defendants, (3) provide proper advice concerning his right to
    take the witness stand, (4) move for severance of his penalty
    phase from that of his co-defendants, (5) adequately investigate
    and prepare mitigating evidence, and (6) move for a new trial.
    Outten II, 
    1997 WL 855718
    , at *76.
    Outten requested an evidentiary hearing on his post-
    conviction claims. 
    Id. at *26.
    The Superior Court ruled that an
    expansion of the trial record was necessary for it to adequately
    address the issues presented.5 
    Id. Thus, “Outten’s
    counsel was
    asked to respond in affidavit form to a series of Court
    questions.” 
    Id. Those questions
    concerned the following
    subjects:
    5
    According to the Superior Court, this was so because “[t]he
    contentions raised against Outten’s trial counsel implicated
    decisions they made and reasons for those decisions which were
    not in the trial record.” Outten II, 
    1997 WL 855718
    , at *26.
    14
    (1) the list of witnesses for the penalty hearing
    that petitioner alleges was given to counsel and
    not investigated, discussions about such witnesses
    with petitioner, and decisions made by counsel
    about which witnesses to produce; (2) the efforts,
    if any, to investigate petitioner’s court and school
    records; (3) any decision made by counsel on how
    to present petitioner at the penalty hearing; (4)
    whether there was a conscious decision to sever
    the penalty hearing [from that of the Sheltons];
    (5) whether advice was given to petitioner not to
    testify during the guilt phase; (6) the substance of
    petitioner’s testimony had he elected to testify; (7)
    whether counsel was aware of petitioner’s
    telephone call from the bar to his girlfriend the
    night of the murder; (8) whether counsel had
    discussed petitioner’s relationship with his father
    beyond the last year of his father’s life; (9)
    whether there was a conscious decision not to
    have a psychiatric examination of petitioner for
    use during the penalty hearing; (10) what role
    petitioner took in any of the above decisions; (11)
    the reasons counsel did not join in Nelson
    Shelton’s motion to sever the guilt phase [from
    the penalty hearing]; and (12) whether counsel
    was aware that petitioner cashed a check on the
    night of the murder at a location other than the
    one testified to by Gibbons.
    15
    Outten IV, 
    2004 U.S. Dist. LEXIS 5546
    , at *25–26. Outten’s
    trial counsel jointly responded by affidavit as directed. 
    Id. at *26.
    Outten and the State, respectively, filed answers to that
    affidavit. 
    Id. After reviewing
    those newly submitted materials,
    the Superior Court concluded that an evidentiary hearing was
    unwarranted. Outten II, 
    1997 WL 855718
    , at *26. It also
    denied Outten’s amended motion for post-conviction relief. 
    Id. at *92.
    Outten appealed to the Delaware Supreme Court the
    ruling of the Superior Court, contending, inter alia, that it erred
    by not holding an evidentiary hearing. Outten v. State, 
    720 A.2d 547
    , 551 (Del. 1998) (Outten III). He also argued that the
    Superior Court abused its discretion in denying his post-
    conviction claims of ineffective assistance of counsel. 
    Id. at 551–58.
    The Supreme Court of Delaware disagreed, and
    affirmed the denial of Outten’s request for post-conviction
    relief. 
    Id. at 558.
    The Superior Court reinstated his death
    sentence and set the date of execution for March 18, 1999.
    E.     Outten’s District Court Habeas Proceedings
    On December 28, 1998, Outten filed in the United States
    District Court for the District of Delaware a 28 U.S.C. § 2254
    pro se petition for a writ of habeas corpus, a 28 U.S.C. § 2251
    motion to stay the state court proceedings, and a motion to
    proceed in forma pauperis. Outten IV, 
    2004 U.S. Dist. LEXIS 5546
    , at *2. The Court granted a stay of execution and the
    16
    motion to proceed in forma pauperis. 
    Id. It also
    entered an
    order appointing counsel and setting a schedule to file an
    amended petition. 
    Id. In October
    1999, Outten filed his first amended habeas
    petition to clarify his grounds for relief. 
    Id. at *2–3.
    He also
    filed a motion to supplement the record with the expert report of
    a post-conviction mitigation specialist, Lori James-Monroe, and
    a motion for an evidentiary hearing on his ineffective assistance
    of counsel claims during both the guilt and penalty stages of the
    trial proceedings. 
    Id. at *3.
    In August 2000, Outten filed his second amended habeas
    petition. He also motioned the Court for an evidentiary hearing
    to expand the record as to “(1) claims relating to [Gibbons]; (2)
    a claim relating to trial counsel’s failure to present a coherent
    case of mitigation at sentencing; and (3) a claim relating to
    [Outten’s] allocution at sentencing.” 
    Id. at *3–4.
    The District
    Court held a limited hearing on Outten’s guilt phase issues, but
    refused to allow him to cross-examine trial counsel concerning
    their efforts to prepare for, investigate, and present a case in
    mitigation at sentencing. 
    Id. at *4.
    It did, however, allow
    Outten to supplement the record with documents retrieved by
    James-Monroe and noted below.
    James-Monroe is a University of Maryland-trained social
    worker who specializes in forensic matters, including mitigation
    in capital cases, and other mental health and psycho-social
    17
    stresses. In preparing her expert report, she interviewed Outten,
    his mother (Carol Outten), his wife (Kathryn Outten), his sisters
    (Robin Outten and Amanda Hart), his brother (John Outten), his
    friends (Debbie Coryell, Mary Owens, Kathy Belford, Karen
    Julian), and a Delaware Division of Child Protective Services
    employee (George Plerhopoles). She also examined the
    following documents: Outten’s first amended petition for
    habeas review, the psychiatric report of Dr. John O’Brien, III,
    William Penn High School records, Child Protective Service
    records, Governor Bacon Mental Health Center records,
    Delaware Correctional Center records, Family Court records,
    and the transcript of trial counsel’s mitigation presentation to the
    jury on March 2, 1993.
    In connection with the last item, James-Monroe opined
    that, “[i]n her professional opinion, no mitigation theme was
    prepared and only ‘sketchy’ family dynamics were introduced in
    the way of testimony. There was no extensive personal history
    presented by an expert, family member or counsel.” James-
    Monroe Report, App. at 170. She also uncovered “[t]he
    following mitigation information [that] was not reported during
    the original penalty phase, although readily available with
    minimal investigation efforts.” 
    Id. at 176.
    Family Issues
    •       Outten was reared by his parents, Carol and
    Foster Outten. Outten’s deceased father, Foster,
    18
    was “abusive and scary.” According to Carol,
    Foster “physically abused her from the time they
    met in 1962, until approximately 1973.” “[H]is
    physical assaults on her transferred to the children
    and everyone in the home felt the emotional
    abuse.” He “would control everyone through his
    violent rages brought on by drinking.” Carol
    explained “that she wanted to leave him or at least
    call the police, but he threatened on many
    occasions to kill her and the children.”
    •   According to Carol, she
    typically worked the 4 p.m. – 12 a.m. shift
    at the [P]ost [O]ffice. Therefore, the
    children were left in the care of their father
    until she arrived home. Many times [when
    she arrived] she found the children in
    corners of the home afraid to move . . . .
    [M]any times the children would have
    been there all day and gone without food
    or completing their homework.
    She recalled that on one occasion [Outten’s sister]
    Amanda had a “black and blue” bruise on her
    forehead from falling asleep in the corner. Carol
    stated that Foster implemented this practice
    because he did not want to “be bothered by the
    19
    children while he drank and watched television.”
    •   Carol would often
    gather the children and leave their home
    after one of her husband’s rages or abusive
    actions. Many times they did not have
    anywhere to go and would walk the streets
    or seek shelter in an abandoned home or
    apartment lobby. They would return home
    hours later, hoping that Foster had “passed
    out from drinking.”
    •   “Each Outten child has stories concerning the
    rage of their [sic] father and their [sic] mother’s
    inability to protect them.” For instance, Outten
    “recalled an incident when the children and Mrs.
    Outten returned from an outing.              Foster
    immediately grabbed John [Outten’s brother] and
    began choking him. Foster exclaimed, ‘you left
    the dog tied up, I am going to show you how it
    feels to choke to death.’” When James-Monroe
    questioned John concerning this event, “he
    immediately began to sob.” After he stopped
    crying he stated:
    Dad said[,] “I want you to feel what the
    dog felt.” He was choking me so hard.
    20
    Mom tried to stop him. He was drunk and
    had a bottle of rum sticking out of his
    pocket. I fell to the floor and I think I was
    unconscious for a little while. I’m not sure
    [who] called the police, but I remember we
    went to [F]amily [C]ourt because of this
    incident. They were going to lock my
    father up for maybe two years. After
    hearing that my mother dropped the
    charges. I left home after that.
    •   In 1974, Foster was attacked and mugged and, as
    a result of those injuries, was diagnosed with
    aphasia—an acquired disorder caused by brain
    damage that affects an individual’s ability to
    communicate.
    Not being able to function as he did in the
    past caused Foster . . . to become more
    aggressive and abusive. In addition, he
    became depressed and his drinking
    increased. The depressed moods coupled
    with intensified drinking led to . . . suicidal
    ideation and suicide attempts. Many times
    the children would find him [o]n the floor
    passed out from taking an overdose of his
    medication or after slitting his wrist . . . .
    The family felt helpless, hopeless and
    21
    guilty, while resenting and being angered
    by his abuse.
    •     Outten has one brother, John, and two sisters,
    Amanda and Robin. Each has suffered from
    alcoholism and/or drug addiction. None of the
    children completed high school.
    •     Outten has fathered three children, Crystal, Foster
    Jack, and Shane. “He maintains contact with his
    daughter through letter writing.” Foster Jack and
    Shane are from the union of Outten and Karen
    Julian. Shane resides in Pennsylvania and Foster
    Jack is deceased.
    Neurologic Issues
    •     During her investigation, James-Monroe
    discovered that, while pregnant with her children,
    Carol drank regularly. “This is through her own
    admission.” In addition to regular drinking,
    Foster physically and mentally abused her. The
    physical abuse included “body blows and punches
    [to] her body and face.” According to James-
    M onroe, “[a]lcohol consumption during
    pregnancy coupled with physical abuse . . . have
    detrimental and long lasting effects on unborn
    children.”
    22
    •    Outten suffered two head trauma injuries as a
    child. During the first incident, Outten’s mother
    pushed him into the side of a porcelain tub,
    causing him to strike his head and, as a result,
    lose consciousness. The second incident, which
    also resulted in a loss of consciousness and
    required medical attention, occurred when he was
    struck in the head with a wrench.
    School Performance
    •    Outten’s school records indicated that he was
    initially placed in a class for the learning disabled
    in 1976 at the age of ten. “It is documented that
    this referral was necessary due to his hyperactivity
    and intellectual ability. In the eighth grade, . . .
    Outten was reading on a third grade level.” A
    1980 evaluation stated:
    Jack is currently functioning at a low
    average level of intelligence.            The
    difference between his verbal I.Q. part of
    the test and the performance section was
    significantly favoring the latter. . . . [His]
    [p]oorest score (retarded level) was
    obtained in the area of concentration.
    •    Dr. David Pearl, a school psychologist who
    23
    evaluated Outten, noted the following in 1982:
    [Jack] was restless, moved his legs back
    and forth, had difficulty maintaining eye
    contact and gave the general impression
    that his problems were “none of my
    business.” He did mention that he had
    been on medication for hyperactivity but
    had stopped taking the pills about a year
    ago. He also noted that he had difficulty
    relating to his father, [and] was frequently
    physically abused by him . . . . Jack made
    only cursory attempts to complete the
    House-Tree-Person drawings and the
    [s]entence completion test. His drawings
    were very small and located at the very top
    of the page on the left hand side[,] which
    is indicative of a restricted personality,
    frustrated in his attempts to attain goals
    which seem unattainable.
    •     After numerous foster care and treatment facility
    placements, Outten withdrew from school in the
    eleventh grade and never graduated from high
    school.
    Psychological Issues
    24
    •   Outten was a victim of violence. Specifically, he
    was the victim of childhood abuse at the
    hands of his father. According to Outten,
    Mr. Plerhopoles [Divison of Family
    Services staff], and family friends,
    Outten’s father . . . was an alcoholic who
    constantly controlled his family with
    physical and emotional abuse . . . . Outten
    suffered and ran away from home at the
    age of sixteen. After running away, he
    was taken in by [a foster] family.
    •   After Outten ran away from home, a series of
    events ensued. He continued to stay with the
    [foster] family.     James-Monroe notes that,
    “[w]hile being cared for by the [foster] family,
    [Outten’s foster mother] began to have
    inappropriate sexual contact with . . . [him].”
    According to Outten, she “initiated the contact by
    placing his hand on her breast. She coerced the
    sixteen-year-old to perform oral sex and fondle
    her.” [Outten’s foster father] discovered this and,
    in July 1982, asked that Outten be removed from
    his home.
    •   Outten was then placed in the Franklin Street
    Shelter for run-away children, where he remained
    25
    for five days before the staff asked that he be
    removed. He was then sent to Camelot Group
    Home, a facility for troubled children. By August
    1982, he was committed to the Governor Bacon
    Health Center. According to Mr. Plerhopoles,
    Governor Bacon had the public reputation of
    being the “dumping ground for [children] that no
    one wanted or knew what to do with.”
    •   Outten was released from Governor Bacon and
    returned home to his family in August 1983.
    Representatives of Governor Bacon described him
    as “depressed and hopeless,” with “difficulty
    expressing his feelings.”
    •   Outten suffered two major losses in his life—the
    death of his father and the death of his young son,
    Jack Foster. Outten’s father died of bone cancer
    in 1991. Despite all of the abuse he suffered at
    the hands of his father, Outten cared for Foster
    entirely during the last six months of his life.
    According to James-Monroe, “[i]t is not
    uncommon for abused children and adult
    survivors to develop attachments to those who
    abuse and neglect them, relationships they will
    strive to maintain even at the sacrifice of their
    own well-being.” In July 1991, Outten fathered a
    child with Karen Julian, Jack Foster. The baby
    26
    only lived fourteen days before dying of many
    complications. According to the Outten family,
    “Julian was using illicit drugs during her
    pregnancy[,] which resulted in the non-
    development of certain of the child’s organs.”
    Substance Abuse
    •         Outten was a substance abuser. He
    admitted to the use of alcohol,
    amphetamines, marijuana, crack cocaine,
    LSD, and the intravenous use of powder
    cocaine. His immediate family [and
    friends] acknowledged this use. . . .
    Outten’s drug use began at the age of 10
    with ‘sneaking’ some of his father’s liquor.
    In addition, he was able to drink with
    neighbors. . . . By the age of 14, he was
    smoking marijuana, which eventually led
    to intravenous cocaine use and late stages
    of alcoholism. . . . His substance abuse
    continued until the date of the underlying
    offense.
    
    Id. at 176–81.
    James-Monroe’s report detailing the above-described
    27
    mitigation evidence not investigated or presented at sentencing
    notwithstanding, the District Court denied relief on all of the
    claims raised in Outten’s § 2254 petition. With respect to trial
    counsel’s duty to investigate, the Court concluded that “trial
    counsel’s overall defense strategy of portraying [Outten] as
    loving, caring, and non-violent,” combined with the hope “that
    the jury would have reservations about [Outten’s] involvement
    in the murder[,] . . . was [a] strategy choice . . . within the range
    of professionally reasonable judgment.” Outten IV, 2004 U.S.
    Dist. LEXIS 5546, at *48–50.
    Despite its denial of habeas relief, the District Court did
    grant a certificate of appealability as to three claims pertaining
    to Outten’s sentencing: whether trial counsel were ineffective
    (1) in their investigation and presentation of mitigating
    evidence, (2) for failing to seek severance of Outten’s penalty
    phase from that of the Shelton brothers, and (3) for failing to
    object to the prosecutor’s comments concerning Outten’s
    allocution to the jury.
    II.    Jurisdiction and Standard of Review
    The District Court had jurisdiction over Outten’s habeas
    petition under 28 U.S.C. § 2254. We have jurisdiction over his
    appeal pursuant to 28 U.S.C. §§ 1291, 2253. Because the
    District Court did not hold an evidentiary hearing on Outten’s
    sentencing claims, we review its legal conclusions de novo.
    Duncan v. Morton, 
    256 F.3d 189
    , 196 (3d Cir. 2001).
    28
    Outten’s petition for habeas relief from his state court
    sentence is governed by the Antiterrorism and Effective Death
    Penalty Act of 1996 (“AEDPA”), 28 U.S.C. §§ 2241–2254.
    AEDPA circumscribes our consideration of Outten’s claims;
    federal habeas relief will only be granted if the state court
    decision being challenged “was contrary to, or involved an
    unreasonable application of, clearly established federal law, as
    determined by the Supreme Court of the United States.” 28
    U.S.C. § 2254(d)(1). In Williams v. Taylor, 
    529 U.S. 362
    (2000), the Supreme Court held that a state court decision is
    “contrary to” clearly established federal law if it (1) “contradicts
    the governing law set forth in [the Supreme] Court’s cases” or
    (2) “confronts a set of facts that are materially indistinguishable
    from a decision of [the Supreme] Court and nevertheless arrives
    at a [different] result.” 
    Id. at 405–06.
    An “unreasonable
    application” of Supreme Court precedent occurs: (1) “if the state
    court identifies the correct governing legal rule from [the
    Supreme] Court’s cases but unreasonably applies it to the facts
    of the particular state prisoner’s case;” or (2) if it “either
    unreasonably extends a legal principle from [Supreme Court]
    precedent to a new context where it should not apply or
    unreasonably refuses to extend that principle to a new context
    where it should apply.” 
    Id. at 407.
    Our review of Outten’s claims under AEDPA is a two-
    step process that proceeds as follows. First, we “‘identify the
    applicable Supreme Court precedent and determine whether it
    resolves . . . [Outten’s] claim[s].’” Hackett v. Price, 
    381 F.3d 29
    281, 287 (3d Cir. 2004) (quoting Werts v. Vaughn, 
    228 F.3d 178
    , 197 (3d Cir. 2000)); see also Matteo v. Superintendent, SCI
    Albion, 
    171 F.3d 877
    , 888 (3d Cir. 1999) (en banc). In
    performing this inquiry, “it is not sufficient for [Outten] to show
    merely that his interpretation of Supreme Court precedent is
    more plausible than the state court’s; rather, [Outten] must
    demonstrate that Supreme Court precedent requires the contrary
    outcome.” 
    Hackett, 381 F.3d at 287
    (quoting 
    Werts, 228 F.3d at 197
    ). “If we determine that the state court decision is not
    ‘contrary to’ the applicable Supreme Court precedent, then we
    are required to advance to the second step in the
    analysis—whether the state court decision was based on an
    ‘unreasonable application of’ Supreme Court precedent.” 
    Werts, 228 F.3d at 197
    (quoting 
    Matteo, 171 F.3d at 888
    ). In doing so,
    “we are not authorized to grant habeas corpus relief simply
    because we disagree with the state court’s decision or because
    we would have reached a different result if left to our own
    devices.” 
    Id. Instead, “the
    state court’s application of Supreme
    Court precedent must have been objectively unreasonable,” that
    is, “[t]he federal habeas court should not grant the petition
    unless the state court decision, evaluated objectively and on the
    merits, resulted in an outcome that cannot reasonably be
    justified under existing Supreme Court precedent.” 
    Hackett, 381 F.3d at 287
    (internal quotations omitted).
    III.   Merits
    A.     Applicable Supreme Court Precedent: Strickland
    30
    v. Washington
    As instructed by Williams, we begin our analysis by
    identifying and discussing the applicable Supreme Court
    precedent. It is well-settled that “the legal principles that govern
    claims of ineffective assistance of counsel [were established by
    the familiar two-pronged test of] Strickland v. Washington, 
    466 U.S. 668
    (1984).” Wiggins v. Smith, 
    539 U.S. 510
    , 521 (2003).
    It is also “past question that . . . Strickland qualifies as ‘clearly
    established [f]ederal law, as determined by the Supreme Court
    of the United States.’” 
    Williams, 529 U.S. at 391
    .
    Under the first prong of Strickland, a petitioner must
    show that trial counsel’s performance was deficient. 
    Strickland, 466 U.S. at 687
    . The proper standard for attorney performance
    is that of “reasonably effective assistance,” as defined by
    “prevailing professional norms.” 
    Id. at 687–88
    (emphasis
    added). In other words, Outten must establish that counsel’s
    representation fell below an objective standard of
    reasonableness. 
    Id. Moreover, counsel’s
    reasonableness must
    be assessed on the facts of the particular case, viewed as of the
    time of counsel’s conduct. 
    Id. at 689.
    Strickland’s second prong requires a petitioner to show
    that “the deficient performance prejudiced the defense.” 
    Id. at 687.
    The prejudice component requires Outten to demonstrate
    “that there is a reasonable probability that, but for counsel’s
    unprofessional errors, the result of the proceeding would have
    31
    been different.” 
    Id. at 694.
    B.     Failure to Investigate
    The first category of Outten’s ineffective assistance of
    counsel challenges relates to his trial attorneys’ investigation
    and preparation for the sentencing hearing after his conviction.
    Outten’s primary argument is that his attorneys failed adequately
    to investigate potentially mitigating evidence, especially the
    effect of his troubled personal and psychiatric background. He
    also contends that his attorneys’ proffered strategy—to reargue
    his innocence at sentencing—was legally impermissible, and
    thus no strategy whatsoever. The Delaware Supreme Court
    determined that Outten could not show that counsel’s
    performance was deficient. Outten 
    III, 720 A.2d at 553
    .
    1.      Was Counsel’s Limited Investigation
    Reasonable?
    In accord with our two-pronged inquiry, we consider
    whether counsel’s investigation was reasonable. According to
    the trial counsel’s joint affidavit, submitted in response to the
    written interrogatories posed by the Delaware Superior Court,
    preparations for Outten’s penalty-phase hearing began
    approximately one month prior to the guilt-phase proceedings.
    See Trial Counsel Aff., App. at 158. Counsel conceded that
    their investigation was cursory, as it consisted simply of a letter
    to Outten asking him to provide “the names of potential penalty
    32
    phase witnesses.” 
    Id. Nothing else
    was done by way of
    investigation except for the conduct of limited discussions with
    Outten and his mother. See 
    id. at 159
    (stating that “[a]fter
    discussing with Mr. Outten his school history[,] . . . we
    confirmed his assessment with his mother and it was determined
    that nothing in his school background would be helpful to . . .
    [Outten] in either the guilt or penalty phases of the [t]rial. As a
    result of our discussions it was determined no[t] to investigate
    the records.” (emphasis added)); see also 
    id. at 160
    (explaining
    that, “as indicated previously[,] based upon the information
    supplied by Mr. Outten and his mother[,] it was determined not
    to pursue the area of psychiatric or psychological disorders”).
    Trial counsel’s affidavit also reveals that, much like their
    counterparts in Strickland, Williams, and Wiggins, Outten’s
    attorneys “attempt[ed] to justify their limited investigation as
    reflecting a tactical judgment not to present mitigating evidence
    at sentencing and to pursue an alternative strategy instead.”
    
    Wiggins, 539 U.S. at 521
    (rejecting the state’s defense of
    counsel’s decision to retry guilt at the sentencing phase);
    
    Williams, 529 U.S. at 373
    (“reject[ing] the argument that
    counsel’s failure to conduct an adequate investigation had been
    a strategic decision to rely almost entirely on the fact that
    Williams had voluntarily confessed”); see also 
    Strickland, 466 U.S. at 673
    . Counsel here specifically viewed the defense
    strategy as an effort to convince the jury that “Outten was loving
    and generous, showing no signs of prior violent behavior,” and
    thus incapable of murder.
    33
    It was determined that we would present
    Jack to the [j]ury as a [y]oung man capable of a
    loving and caring existence. A man who had no
    history of violence. A man who was capable of
    holding a job and support[ing] a family. . . .
    It was determined that all negatives,
    abusive childhood, truancy and school problems
    would be counterproductive.            The theme
    throughout the guilt phase and the penalty phase
    was to remain consistent, that is, Jack Outten did
    not commit the murder. It was determined that
    this could best be carried out by presenting Outten
    as we did.
    Trial Counsel Aff., App. at 158. Trial counsel further stated that
    “[i]t is conceded that an expert could have been retained to
    develop a mental crutch (conclusion is reached based on
    experience)[;] however, it was determined that a consistent
    defense of not offering excuses for Outten’s actions but a
    continued denial was in his best interest.” 
    Id. at 163
    (emphasis
    added).
    Simply stated, defense counsel’s penalty-phase strategy
    was to argue to the jury—which had convicted Outten of murder
    unanimously and beyond a reasonable doubt—that he was a
    good guy and that his life should be spared because he was
    actually innocent. See 
    id. at 159
    (stating that “[i]t was
    34
    determined that we should stick with our original theory, Jack
    was innocent, as supported by his penalty phase witnesses”
    (emphasis added)); 
    id. at 160
    (explaining that “[t]he
    determination was to represent Jack as a party not involved in
    the murder at the trial phase and to maintain that position
    throughout the penalty phase so as to retain credibility with the
    jury” (emphasis added)).
    But in closing comments at the penalty phase, trial
    counsel did not carry through this tack. When trial counsel tried
    to pursue Outten’s actual innocence argument explicitly, the
    prosecution objected and the trial court disallowed it, stating
    “[t]hat’s improper argument[,] . . . rearguing the issue of guilty
    or not guilty.” See App. at 126. Counsel responded, “I’m not
    arguing the issue of guilty or not . . . . [Outten] was guilty.” 
    Id. When counsel
    again attempted to discuss “the testimony or
    evidence that [Outten] didn’t do it,” the trial judge
    unequivocally instructed that there was to be no further
    presentation of that issue. 
    Id. Ultimately, the
    innocence strategy was abandoned in
    closing. Counsel stated that it “wasn’t too difficult to decide”
    that Outten and his co-defendants were responsible for the
    victim’s death. 
    Id. at 121.
    He mentioned Outten’s “horrendous
    record,” and then stated, “We’re not here to decide what he did
    in this particular case. He’s guilty.” 
    Id. at 122.
    Counsel
    described Outten’s family as “the other victims in this case.” 
    Id. at 125.
    He stated that “they’re here because Jack Outten put
    35
    them here. He didn’t have to go to that bar that evening. He
    could have stayed home.” 
    Id. Counsel also
    failed in closing to focus on the positive
    aspects of Outten’s character. While he did mention that Outten
    had no convictions for violent crimes, he did so by referring to
    Outten’s “long criminal record,” and stated that “Jack Outten
    was on the street for a long time committing crimes, but there’s
    no history of violence.” 
    Id. at 124.
    Indeed, any contention that
    Outten was non-violent was substantially undermined by the
    cross-examination testimony elicited by the prosecution from
    various family members describing Outten’s assaults on his
    sister Amanda, his ex-girlfriend Julian, and other individuals.
    There was no mention of Outten being loving and generous or
    that he was capable of holding down a job. The jury was not
    reminded of Outten’s caring for his dying father or helping his
    sister Amanda with child care. “When viewed in this light, the
    ‘strategic decision’ the state courts and [counsel] . . . invoke to
    justify counsel’s limited pursuit of mitigating evidence
    resembles more of a post hoc rationalization of counsel’s
    conduct than an accurate description of their deliberations prior
    to sentencing.” 
    Wiggins, 539 U.S. at 526
    –27; see also 
    id. at 526
    (stating that “[t]he record of the actual sentencing proceedings
    underscores the unreasonableness of counsel’s conduct by
    suggesting that their failure to investigate thoroughly resulted
    from inattention, not reasoned strategic judgment”).
    Counsel made clear they neither acquired nor reviewed
    36
    readily available school and medical health records. See Outten
    II, 
    1997 WL 855718
    at *86 (reiterating that “[i]t is undisputed
    trial counsel did not examine these records”). They also
    explained that their decision to refrain from such an
    investigation stemmed entirely from conversations with Outten
    and his mother. Thus, similar to the attorneys in 
    Wiggins, 539 U.S. at 537
    –38 (holding that counsel’s decision not to expand
    their investigation beyond the perusal of limited government
    records and the arrangement of psychological testing for their
    client was unreasonable), Outten’s trial counsel acquired
    whatever “rudimentary knowledge” of Outten’s background
    they did have from a “narrow set of sources,” 
    id. at 524.
    We need to resolve whether this limited investigation
    from a “narrow set of sources” was reasonable. The Supreme
    Court has explained the deference owed to strategic decisions of
    counsel by reference to the scope of the investigations
    supporting those decisions:
    [S]trategic choices made after thorough
    investigation of law and facts relevant to plausible
    options are virtually unchallengeable; and
    strategic choices made after less than complete
    investigation are reasonable precisely to the extent
    that reasonable professional judgments support
    the limitations on investigation. In other words,
    counsel has a duty to make reasonable
    investigations or to make a reasonable decision
    37
    that makes particular investigations unnecessary.
    In any ineffectiveness case, a particular decision
    not to investigate must be directly assessed for
    reasonableness in all the circumstances, applying
    a heavy measure of deference to counsel’s
    judgments.
    
    Strickland, 466 U.S. at 690
    –91. Put another way, the question
    before us is not whether counsel should have introduced
    mitigating evidence of Outten’s background. It is “whether the
    investigation supporting counsel’s decision not to introduce
    mitigating evidence of [Outten’s] background was itself
    reasonable.” 
    Wiggins, 539 U.S. at 511
    (emphasis in original).
    Reasonableness in this context is assessed by looking to
    “[p]revailing norms of practice as reflected in [the] American
    Bar Association standards.” 
    Strickland, 466 U.S. at 688
    ; see
    also Rompilla v. Beard, 
    545 U.S. 374
    , 375 (2005) (explaining
    that the Court has long “referred [to the ABA Standards for
    Criminal Justice] as guides to determining what is reasonable”
    (internal quotations omitted)); 
    Wiggins, 539 U.S. at 522
    (stating
    that “[i]n highlighting counsel’s duty to investigate,” the Court
    “refer[s] to the ABA Standards for Criminal Justice as guides”);
    Marshall v. Cathel, 
    428 F.3d 452
    , 463 (3d Cir. 2005) (“An
    attorney’s duty to investigate is itself judged under a
    reasonableness standard based on ‘prevailing professional
    norms[,]’ such as those found in the ABA Standards for
    Criminal Justice.”).
    38
    In 1989, four years prior to Outten’s penalty-phase
    hearing, the ABA promulgated guidelines for defense attorneys
    in capital cases. See American Bar Association Guidelines for
    the Appointment and Performance of Counsel in Death Penalty
    Cases (1989) (“ABA Guidelines”). “Those Guidelines applied
    the clear requirements for investigation set forth in the earlier
    Standards to death penalty cases and imposed . . . similarly
    forceful directive[s].”   
    Rompilla, 545 U.S. at 376
    n.7.
    Concerning penalty-phase preparation and investigation, the
    Guidelines provide:
    A.     Counsel        should     conduct
    independent investigations relating
    to the guilt/innocence phase and to
    the penalty phase of a capital trial.
    Both investigations should begin
    immediately upon counsel’s entry
    into the case and should be pursued
    expeditiously.
    ...
    C.     The investigation for preparation of
    the sentencing phase should be
    conducted regardless of any initial
    assertion by the client that
    mitigation is not to be offered. This
    investigation should comprise
    39
    efforts to discover all reasonably
    available mitigating evidence and
    evidence to rebut any aggravating
    evidence that may be introduced by
    the prosecutor.
    ABA Guideline 11.4.1 (1989) (emphasis added). Counsel
    should explore, inter alia, “medical history,” “family and social
    history,” “educational history,” “special educational needs,”
    “employment and training history,” “prior adult and juvenile
    records,” and “prior correctional experience.” ABA Guideline
    11.4.1(D)(2)(C). The ABA Guidelines go on to explain that
    [t]he need for a standard mandating investigation
    for the sentencing phase is underscored by cases
    in which counsel failed to recognize the
    importance of this aspect of death penalty
    litigation. Inexperienced counsel — and even
    counsel experienced in non-capital cases — “may
    underestimate the importance of developing
    meaningful sources of mitigating evidence . . .”
    See Guideline 11.8 and commentary.
    Counsel’s duty to investigate is not negated
    by the expressed desires of a client. Nor may
    counsel “sit idly by, thinking that the investigation
    would be futile.” The attorney must first evaluate
    the potential avenues of action and then advise the
    40
    client on the merits of each.          Without
    investigation, counsel’s evaluation and advice
    amount to little more than a guess.
    ABA Guideline 11.4.1, commentary (1989) (internal footnote
    omitted) (emphasis added); see also 1 ABA Standards for
    Criminal Justice 4–4.1, commentary (2d ed. 1982) (stating “[t]he
    lawyer . . . has a substantial and important role to perform in
    raising mitigating factors both to the prosecutor initially and to
    the court at sentencing . . . . Investigation is essential to
    fulfillment of these functions.”).
    “Despite these well-defined norms, however, counsel
    [here] abandoned their investigation of [Outten’s] background
    after having acquired only rudimentary knowledge of his history
    from a narrow set of sources.” 
    Wiggins, 539 U.S. at 524
    . It was
    standard practice at the time of Outten’s trial for a death-eligible
    defendant’s penalty-phase investigation to include his medical
    history, educational history, family and social history,
    employment history, and adult and juvenile correctional records.
    Counsel’s investigation, however, was limited solely to
    conversations with Outten and his mother—a woman who, as
    demonstrated by the unreviewed-by-counsel records, had not
    “shown great[] continued interest in [her son].” See Report of
    James-Monroe, App. at 180. We conclude that this effort fell
    well short of the national prevailing professional standards
    articulated by the American Bar Association and was, therefore,
    unreasonable. See 
    Wiggins, 539 U.S. at 524
    (holding that
    41
    counsel’s decision not to expand their investigation to
    petitioner’s life history, beyond review of a presentence report
    and social service records, failed to meet the prevailing
    standards of attorney conduct).
    Counsel’s cursory investigation was also unreasonable in
    light of what they presumably discovered from the conversations
    with Outten and his mother prior to sentencing: Outten’s father
    was an abusive alcoholic; Outten had struggled in school and
    ultimately failed to graduate; he had run away from home; and
    he had a history of substance abuse.6 
    Id. at 527
    (explaining that
    courts must consider whether the evidence known to counsel
    “would lead a reasonable attorney to investigate further”).
    6
    The record does not reflect the content of counsel’s
    conversations in this regard. We presume that counsel
    discovered information concerning Outten’s abusive father,
    struggles in school, and substance abuse during their
    conversations with Outten and his mother because they testified
    as to those facts on direct examination during the sentencing
    proceedings. Moreover, in their affidavit, trial counsel noted
    that, prior to sentencing, they “determined that all negatives,
    abusive childhood, truancy and school problems would be
    counterproductive.” Trial Counsel Aff., App. at 158. Because
    counsel limited their sentencing investigation exclusively to
    Outten and his mother, either Outten or his mother—or
    both—must have been the source of counsel’s information on
    those “negatives.” In any event, counsel acknowledge that they
    were aware of the abuse and school problems.
    42
    “[A]ny reasonably competent attorney would have realized that
    pursuing those leads was necessary to make an informed choice
    among possible [sentencing strategies].” 
    Id. at 525.
    “Indeed,
    counsel uncovered no evidence in their investigation to suggest
    that a mitigation case, in its own right, would have been
    counterproductive, or that further investigation would have been
    fruitless . . . .” 
    Id. Moreover, as
    in Wiggins, “[h]ad counsel
    investigated further [here], they might well have discovered the
    sexual abuse [Outten suffered at the hands of his foster mother]
    revealed during . . . postconviction proceedings.” 
    Id. As noted
    above, the prevailing professional norms for
    capital cases at the time of Outten’s trial instructed defense
    counsel “to discover all reasonably available mitigating
    evidence and evidence to rebut any aggravating evidence that
    may be introduced by the prosecutor.” ABA Guideline 11.4.1
    (emphasis added). Given the minimal investigation conducted
    here, trial counsel’s evaluation of which defense strategy to
    pursue “amounted to little more than a[n] [uninformed] guess.”
    Id.; see also 
    Wiggins, 539 U.S. at 527
    . Simply stated, failing to
    present possibly mitigating evidence cannot be justified when
    counsel have not “fulfill[ed] their obligation to conduct a
    thorough investigation of the defendant’s background.”
    
    Williams, 529 U.S. at 396
    (citing 1 ABA Standards for Criminal
    Justice 4–4.1, commentary).         Accordingly, we hold the
    Delaware Supreme Court’s 1998 ruling in Outten III—that the
    limited scope of trial counsel’s investigation was adequate under
    the prevailing norms of professional conduct at the time of
    43
    Outten’s trial—was an objectively unreasonable application of
    the first prong of the Strickland inquiry.
    2.     Was Counsel’s Unreasonable Investigation
    Prejudicial?
    Because trial counsel’s failure to investigate Outten’s
    background was unreasonable, we proceed to whether that error
    was prejudicial—that is, whether “there is a reasonable
    probability that, but for counsel’s unprofessional errors, the
    result of the proceeding would have been different.” 
    Strickland, 466 U.S. at 694
    . “A reasonable probability is a probability
    sufficient to undermine confidence in the outcome.” 
    Id. “In assessing
    prejudice, we reweigh the evidence in aggravation
    against the totality of available mitigating evidence.” 
    Wiggins, 539 U.S. at 534
    .
    The James-Monroe report shows substantial evidence in
    mitigation that counsel failed to investigate and present at
    sentencing.     In particular, Outten experienced severe
    mistreatment as a child from his “abusive and scary” alcoholic
    father. James-Monroe Report, App. at 176. Outten’s father
    physically assaulted and emotionally tormented his wife and
    children routinely, even “threaten[ing] on many occasions to kill
    [them].” 
    Id. When Mrs.
    Outten returned home from work, she
    often found the children huddled in a corner, afraid to move. 
    Id. at 177.
    “[M]any times the children would have been there all
    day and gone without food or completing their homework.” 
    Id. 44 Frequently,
    Mrs. Outten and her children were forced to “walk
    the streets or seek shelter in an abandoned home or apartment
    lobby” in order to avoid Mr. Outten’s “rages or abusive actions.”
    
    Id. Outten’s brother
    John related an incident where, because
    he had left the dog tied up, his father choked him to the point of
    unconsciousness so that he would know “how it feels to choke
    to death.” 
    Id. As Mr.
    Outten physically deteriorated, he became
    suicidal and often the children would find him passed out,
    having overdosed on medication and/or slit his wrists. 
    Id. “Each of
    the Outten children has stories concerning the rage of
    their father and their mother’s inability to protect them.” 
    Id. Neither Outten
    nor any of his siblings completed high school.
    
    Id. at 178.
    Moreover, they all suffered from alcoholism and/or
    drug addiction. 
    Id. at 177–78.
    In addition to the considerable evidence of child abuse,
    James-Monroe discovered “easily accessible” documented
    evidence of neurological damage, poor school performance, low
    IQ, learning disabilities, placement in foster homes, sexual
    abuse, and substance abuse. 
    Id. at 176–81.
    Even a superficial
    investigation into Outten’s school records reveals that he
    functioned during his developmental years at a below-average
    level of intelligence and, specifically, at a retarded level in the
    area of concentration. 
    Id. at 180.
    Outten “thus has the kind of
    troubled history we have declared relevant to assessing a
    defendant’s moral culpability.” 
    Wiggins, 539 U.S. at 535
    ; see
    45
    also Penry v. Lynaugh, 
    492 U.S. 302
    , 319 (1989) (stating that
    “evidence about the defendant’s background and character is
    relevant because of the belief, long held by society, that
    defendants who commit criminal acts that are attributable to a
    disadvantaged background . . . may be less culpable than
    defendants who have no such excuse”).
    The Delaware Supreme Court held that Outten’s
    allegations concerning the limited scope of counsel’s
    investigation of his background failed to satisfy the prejudice
    prong of Strickland. Outten 
    III, 720 A.2d at 553
    . We disagree.
    The Court’s conclusion was premised on evidence that “counsel
    made some effort to discover whether there was any useful
    information in Outten’s school records,” and that “information
    regarding [Outten’s] substance abuse problem, truancy trouble
    in school, appearances in Family Court, criminal activity, and
    abusive and alcoholic father came out in the testimony during
    the penalty phase hearing.” 
    Id. In another
    context, we have rejected expressly the
    Pennsylvania Supreme Court’s conclusion that the failure to
    present additional mitigating evidence was not prejudicial
    simply because the jury had some awareness of a petitioner’s
    childhood and mental illness:
    [T]he Commonwealth fails to appreciate the fact
    that the only evidence specifically pertaining to
    Jermyn’s childhood abuse came from Reverend
    46
    Falk, whose testimony, to which we have already
    alluded, was limited, equivocal, and misleading.
    While the jury was clearly aware that Jermyn
    claimed that he suffered a mental illness, the lack
    of directed and specific testimony about Jermyn’s
    childhood and its impact on Jermyn’s mental
    illness left the jury’s awareness incomplete. We
    therefore do not agree with the Pennsylvania
    Supreme Court’s characterization that the
    evidence that could have been presented would
    simply “have provided the jury with more detailed
    incidents of his childhood trauma and mental
    illness.” Rather, the testimony would have
    provided the jury with an entirely different view
    of Jermyn’s life and childhood which would have
    both aided in understanding the seriousness and
    origin of his mental illness and provided an
    understanding of Jermyn’s relationship with the
    deceased.
    Jermyn v. Horn, 
    266 F.3d 257
    , 310–11 (3d Cir. 2001) (internal
    footnote and citations omitted).
    The same logic applies here. Simply because some
    mitigating evidence regarding Outten’s abusive childhood was
    introduced to the jury—despite defense counsel’s contrary
    intentions, see Trial Counsel Aff., App. at 158 (stating that the
    defense strategy was not to introduce any evidence of Outten’s
    47
    “abusive childhood” or “school problems”)—it does not follow
    that the jury was provided a comprehensive understanding of
    Outten’s abusive relationship with his father or other aspects of
    his troubled childhood. For example, while Outten’s mother
    portrayed her husband as a “very, very strict parent,” she did not
    relate to the jury the disturbing abuse she later described to
    James-Monroe in detail. In any event, the jury heard nothing
    regarding Outten’s sexual abuse in foster care, possible
    neurological damage, learning disabilities, or low IQ.
    Here, “counsel chose to abandon their investigation at an
    unreasonable juncture, making a fully informed decision with
    respect to sentencing strategy impossible.” 
    Wiggins, 539 U.S. at 527
    –28. As we have already explained, the state court’s
    ruling that the scope of counsel’s investigation was adequate
    was an unreasonable application of Strickland.         Thus, its
    subsequent deference to counsel’s decision not to “pursue all
    lines of investigation,” Outten 
    III, 720 A.2d at 553
    (internal
    quotations omitted), “despite the fact that counsel based this
    alleged choice on what we have made clear was an unreasonable
    investigation, was also objectively unreasonable.” 
    Wiggins, 539 U.S. at 528
    . This is because “strategic choices made after less
    than complete investigations are [only] reasonable . . . to the
    extent that reasonable professional judgments support the
    limitations on investigations.” 
    Strickland, 466 U.S. at 690
    –91.
    The State counters that trial counsel would have
    proceeded with their “reasonable” strategy of presenting Outten
    48
    as kind, caring, and ultimately innocent, notwithstanding the
    mitigating evidence they failed to discover. In Wiggins, the
    State of Maryland offered a similar contention, “maintaining
    that Wiggins’ counsel would not have altered their chosen
    strategy of focusing exclusively on Wiggins’ direct
    responsibility for the 
    murder.” 539 U.S. at 536
    . The Supreme
    Court flatly rejected this logic, explaining that
    counsel were not in a position to make a
    reasonable strategic choice as to whether to focus
    on Wiggins’ direct responsibility, the sordid
    details of his life history, or both, because the
    investigation supporting their choice was
    unreasonable.
    
    Id. The same
    analysis applies here. Counsel for Outten were
    not in a position to make a reasonable decision whether to focus
    on his innocence or positive characteristics, the details of his
    traumatic background, or both, as their investigation in
    preparation for sentencing was itself unreasonably deficient.
    Moreover, as already discussed, counsel’s presentation at
    sentencing hardly reflected their stated strategy. The innocence
    argument was never presented to the jury because the trial judge
    disallowed it. To make matters worse, counsel then did an
    “about face” by proclaiming to the jury in closing that “it wasn’t
    too difficult to decide” that Outten had murdered Mannon. To
    hammer home the point, counsel explicitly stated, “He’s guilty.”
    49
    Trial counsel’s sentencing presentation also failed to
    focus on evidence indicating Outten’s good character traits. As
    stated above, counsel did argue that Outten had no convictions
    for violent crimes, but he did so by referring to Outten’s “long
    criminal record” and stated that “Jack Outten was on the street
    for a long time committing crimes, but there’s no history of
    violence.” In closing, counsel neglected to remind the jury that
    Outten was capable of holding down a job, had cared for his
    dying father, or had assisted his sister with child care. Worse
    yet, the contention that Outten was non-violent was considerably
    undermined by the cross-examination testimony of various
    family members describing Outten’s physical attacks on his
    sister and ex-girlfriend—damaging testimony that could have
    been factored into trial counsel’s strategic decision had counsel
    interviewed those witnesses prior to sentencing.
    The State asserts, and we acknowledge, that not all of the
    evidence in the records counsel failed to investigate is favorable
    to Outten. This is nearly always the case. Indeed, the same was
    true of the evidence not investigated by counsel in Williams.
    There, the Supreme Court observed that “the failure to introduce
    the comparatively voluminous amount of evidence that did
    speak in Williams’ favor was not justified by . . . [the] decision
    to focus on Williams’ voluntary confession.” 
    Williams, 529 U.S. at 398
    . The same is true here; the failure to introduce
    considerable evidence that could have been helpful to Outten
    was not justified by counsel’s belief, without an adequate
    investigation, that the net result of any investigation would be
    50
    negative. In fact, much of the aggravating evidence in the
    records was either introduced or elicited on cross-examination
    by the State at sentencing. The more important point here,
    however, is while it is true that trial counsel may not have
    introduced into evidence all of Outten’s records at sentencing if
    they had procured them, the records most certainly would have
    informed counsel’s preparation. Moreover, given the jury’s
    close vote in favor of death for Outten—7 to 5—counsel would
    have had the ability to argue a much broader range of mitigating
    factors than the four that were presented to the jury.7
    In this context, we conclude that the Delaware Supreme
    Court unreasonably applied the second prong of Strickland in
    reaching the determination that Outten could not establish
    prejudice because Outten’s records contained some harmful
    information. See Outten 
    III, 720 A.2d at 552
    (approving the
    Superior Court’s reasoning that Outten’s “ records contained
    both mitigating and aggravating information which, at best,
    cancel each other out . . . [; thus] trial counsel cannot be faulted
    for not investigating them [because,] in all likelihood, the
    7
    For example, notwithstanding the emotional and physical
    abuse Outten suffered at the hands of his father, the record
    reflects that Outten forgave him and remained by his side during
    his final months of life. In this context, it seems that revealing
    the severity of Mr. Outten’s abuse of his children would have
    bolstered and complemented—rather than detracted from—the
    defense’s portrait of Outten as caring and compassionate.
    51
    records would not have been used”) (internal quotations
    omitted)). In effect, despite the fact that there was a wealth of
    readily accessible mitigating evidence here, the jury heard little
    of it. In evaluating the totality of the evidence, both introduced
    at trial and in the habeas proceedings, we conclude that “[h]ad
    the jury been able to place [Outten’s] excruciating life history on
    the mitigating side of the scale, there is a reasonable probability
    that at least one juror [or more] would have struck a different
    balance.” 
    Wiggins, 539 U.S. at 537
    .              Because the jury
    recommended death by the narrow margin of 7 to 5, persuading
    even one juror to vote for life imprisonment could have made all
    the difference. This without doubt satisfies Strickland’s
    prejudice prong.

    For the reasons provided above, we hold that the state
    court’s ruling that the limited scope of trial counsel’s
    investigation did not constitute ineffective assistance of counsel
    was an objectively unreasonable application of Strickland.
    Because counsel’s penalty-phase investigation was unreasonably
    deficient and prejudicial, Outten is entitled to habeas relief. We
    reverse and remand this case to the District Court with
    instructions to grant a provisional writ of habeas corpus directed
    to the penalty phase. Within 120 days of the judgment
    accompanying this opinion, the State of Delaware may conduct
    a new sentencing hearing in a manner consistent with this
    opinion or sentence Outten to life imprisonment.
