    PEOPLE v ACKLEY
    Docket No. 149479. Argued March 10, 2015. Decided June 29, 2015.
    Leo D. Ackley was convicted by a jury in the Calhoun Circuit Court of first-degree
    felony murder, MCL 750.316(1)(b), and first-degree child abuse, MCL 750.136(b)(2), after his
    live-in girlfriend’s three-year-old daughter died while in his care. At trial, the prosecution called
    five medical experts who testified that the child had died as the result of a head injury that was
    caused intentionally, while defense counsel called no experts, despite having been provided court
    funding for expert assistance and the name of a well-known forensic pathologist who could
    support the defense theory that the injuries had resulted from an accidental fall. Defendant
    appealed his convictions as of right, arguing that his lawyer’s failure to meaningfully challenge
    the prosecution’s expert testimony violated his Sixth Amendment right to the effective assistance
    of counsel. The Court of Appeals, BOONSTRA, P.J., and SAWYER and SHAPIRO, JJ., remanded the
    matter for an evidentiary hearing under People v Ginther, 
    390 Mich. 436
    (1973), after which the
    trial court, James C. Kingsley, J., granted defendant’s motion for a new trial. The prosecution
    appealed. The Court of Appeals, OWENS, P.J., and MURRAY and RIORDAN, JJ., reversed in an
    unpublished opinion per curiam issued April 22, 2014 (Docket No. 318303), holding that the
    trial court had abused its discretion by granting a new trial because defense counsel’s decisions
    regarding experts were trial strategy and no prejudice had resulted. Defendant appealed. The
    Supreme Court ordered and heard oral argument on whether to grant the application for leave to
    appeal or take other peremptory action, limited to the issue whether defendant was denied the
    effective assistance of counsel based on trial counsel’s failure to adequately investigate the
    possibility of obtaining expert testimony in support of the defense. 
    497 Mich. 910
    (2014).
    In a unanimous opinion by Justice MCCORMACK, the Supreme Court, in lieu of granting
    leave to appeal, held:
    Defendant was denied the effective assistance of counsel by his trial counsel’s failure to
    investigate adequately and to attempt to secure suitable expert assistance in the preparation and
    presentation of his defense. Expert testimony was critical in this case to explain whether the
    cause of the child’s death was intentional or accidental. Defense counsel’s failure to attempt to
    engage a single expert witness to rebut the prosecution’s expert testimony, or to attempt to
    consult an expert with the scientific training to support the defense theory of the case, fell below
    an objective standard of reasonableness, and there was a reasonable probability that this error
    affected the outcome of the trial. Accordingly, defendant was entitled to a new trial.
    1. The Court of Appeals erred by concluding that defense counsel’s decision to consult
    only Dr. Brian Hunter in preparation for trial was objectively reasonable. There was no
    objectively reasonable explanation in the record for counsel’s decision to confine his pursuit of
    expert assistance to Hunter, a self-proclaimed opponent of the very defense theory counsel was
    to employ at trial, despite Hunter’s having referred counsel to at least one other expert who could
    provide qualified and suitable assistance. Counsel’s failure to engage expert testimony rebutting
    the state’s expert testimony and failure to become versed in the technical subject matter
    constituted a constitutional flaw in the representation, not reasonable strategy. Given the
    centrality of expert testimony to the prosecution’s proofs and the highly contested nature of the
    underlying medical issue, counsel’s single error of failing to consult an expert who could
    meaningfully assist him constituted ineffective assistance.
    2. But for counsel’s deficient performance, there was a reasonable probability that the
    outcome of defendant’s trial would have been different. Defendant’s conviction turned on the
    jury’s assessment of the prosecution’s theory that the child’s fatal injuries were the result of
    intentional abuse, which was advanced through the testimony of five experts. Because
    defendant’s own testimony and that of his lay character witnesses were extremely unlikely to
    counter this formidable expert testimony, expert assistance in defendant’s favor was critical to
    provide the jury with another viable and impartial perspective on the facts of the case while
    contradicting the prosecution’s theory of how the child died. The prosecution’s voluminous
    expert testimony made the need for an effective response by defense counsel particularly
    apparent and strong, and it rendered counsel’s failure to offer expert testimony particularly
    glaring and harmful to the defendant. This consequence militated in favor of defendant’s claim
    of relief. Further, the prosecution’s nonexpert evidence was highly circumstantial, heavily
    contested, and far from dispositive of the issue of defendant’s guilt. While a battle of the experts
    might not have ensured defendant’s acquittal, counsel’s failure to prepare or show up for the
    battle sufficiently undermined confidence in the outcome of this case to entitle defendant to
    relief.
    Court of Appeals judgment reversed; conviction vacated; case remanded to the trial court
    for further proceedings.

    PEOPLE OF THE STATE OF MICHIGAN,
    Plaintiff-Appellee,
    v                                                               No. 149479

    Defendant-Appellant.
    BEFORE THE ENTIRE BENCH
    MCCORMACK, J.
    The question before us is whether the defendant was denied the effective
    assistance of counsel by his trial counsel’s failure to investigate adequately and to attempt
    to secure suitable expert assistance in the preparation and presentation of his defense. In
    this case involving the unexplained and unwitnessed death of a child, expert testimony
    was critical to explain whether the cause of death was intentional or accidental. Contrary
    to the determination of the Court of Appeals, we conclude that defense counsel’s failure
    to attempt to engage a single expert witness to rebut the prosecution’s expert testimony,
    or to attempt to consult an expert with the scientific training to support the defendant’s
    theory of the case, fell below an objective standard of reasonableness, and created a
    reasonable probability that this error affected the outcome of the defendant’s trial. See
    Strickland v Washington, 
    466 U.S. 668
    , 694; 
    104 S. Ct. 2052
    ; 
    80 L. Ed. 2d 674
    (1984).
    Accordingly, we reverse the judgment of the Court of Appeals, vacate the defendant’s
    convictions, and remand for proceedings consistent with this opinion.
    I. FACTS AND PROCEDURAL HISTORY
    The defendant was convicted by a jury of first-degree felony murder,
    MCL 750.316(1)(b), and first-degree child abuse, MCL 750.136b(2), after his live-in
    girlfriend’s three-year-old daughter died while in his care. According to the defendant,
    the child had been napping alone in her room before he discovered her lying
    unresponsive on the floor next to the bed. The prosecution alleged that the defendant
    killed the child, either by blunt force trauma or shaking. The defendant denied hurting
    the child, and said that she must have died as the result of an accidental fall.
    Given the lack of eyewitness testimony and any other form of direct evidence,
    expert testimony was the cornerstone of the prosecution’s case. The prosecution called
    five medical experts to testify at trial about the cause of the child’s death: two general
    pediatricians, a pediatric critical care doctor, a trauma surgeon, and a forensic
    pathologist. 1 Each testified that the child died as a result of abusive head injury caused
    1
    The prosecution also called an expert in emergency medicine, who testified regarding
    the child’s initial triage and treatment in the Battle Creek Health Systems Emergency
    Department.
    2
    either by nonaccidental shaking, blunt force trauma, or a combination of both. The
    defense, in contrast, called no expert in support of its theory that the child’s injuries
    resulted from an accidental fall, although the court had provided funding for expert
    assistance.
    The defendant appealed his convictions as of right, arguing that he was entitled to
    a new trial because his lawyer’s failure to meaningfully challenge the prosecution’s
    expert testimony regarding the cause of the child’s death violated his Sixth Amendment
    right to the effective assistance of counsel. The Court of Appeals remanded for an
    evidentiary hearing pursuant to People v Ginther, 
    390 Mich. 436
    ; 212 NW2d 922 (1973).
    People v Ackley, unpublished order of the Court of Appeals, entered May 24, 2013
    (Docket No 310350).
    At the Ginther hearing, the defendant’s trial counsel testified that he contacted
    only one expert to prepare for trial: forensic pathologist Brian Hunter. Dr. Hunter
    testified that, after reviewing some of the case materials, he advised counsel “right off the
    bat” that he was “not the best person” for the defense. He also explained to counsel that
    there was a marked difference of opinion within the medical community about
    diagnosing injuries that result from falling short distances, on the one hand, and shaken
    baby syndrome (SBS) or, as it is sometimes termed, abusive head trauma (AHT), on the
    other hand. Hunter asserted that this divide is “like a religion” because each expert has
    deeply held beliefs about when each diagnosis is supported, and the defendant should
    have the benefit of an expert who, “[i]n his or her religion, believes this could be a short-
    fall death.” Hunter emphasized to counsel that he was on the wrong side of this debate to
    be able to assist the defendant.
    3
    Hunter then referred counsel to at least one well-known forensic pathologist, 2 Dr.
    Mark Shuman, who had conducted substantial research on short falls.                Hunter
    characterized Dr. Shuman as the “best person” to assess the “complex” short-fall
    mechanism involved in the defendant’s theory.       Hunter could not promise that Dr.
    Shuman would “buy into every story the defendant is selling,” but he informed counsel
    that Dr. Shuman was a “man of science . . . he’s the guy that’s going to give you your
    best shot.”
    Counsel testified that he never contacted Shuman, or any other expert in short
    falls. Nor did he read any medical treatises or other articles about the medical diagnoses
    at issue. Though recognizing that expert testimony can carry great weight with a jury, he
    nevertheless stated that while it may have been “prudent” for him to have consulted “the
    over 400 treatises available” in preparing his cross-examinations of the prosecution’s
    experts “that wasn’t the strategy.” 3 Instead, he requested a second consultation with
    Hunter, offering the simple (albeit inexplicable) justification that Dr. Shuman “was not
    going to work out.” Hunter reiterated his concerns with defense counsel’s choice to use
    him, unambiguously warning counsel again that “you don’t want me as your defense
    expert.”
    2
    There was conflicting testimony between Hunter and defense counsel about Hunter’s
    referral(s). According to counsel, Hunter referred him to two experts: Dr. Shuman and
    Dr. Werner Spitz. According to Hunter, he referred counsel to Dr. Shuman only. In any
    event, counsel admitted that he never contacted either expert.
    3
    Defense counsel explained that he preferred to attack the experts exclusively through
    the “gray area” that Hunter supplied—namely, that there had been no studies as to the
    actual force necessary to achieve fatal blunt-force head injuries in children.
    4
    Counsel testified that he nevertheless continued to rely on only Hunter in his trial
    preparation, consulting him at least two more times before trial. Specifically, counsel
    provided Hunter with additional—but incomplete 4—portions of the case materials so that
    Hunter could give counsel advice on how to approach the prosecution’s experts. Counsel
    admitted that Hunter’s advice was his only method of preparing to cross-examine the
    prosecution’s experts on the viability of their SBS/AHT theory of the child’s cause of
    death. 5
    Finally, the parties stipulated to the admission of an affidavit from Dr. Werner
    Spitz, another well-known expert in forensic pathology. After reviewing the autopsy
    report, postmortem photographs, and the trial transcripts, Dr. Spitz opined that the bruises
    on the child’s body were consistent with the intubation and CPR she received on the day
    of her death. He then averred that he would have testified that the child’s head injuries
    could not be attributed to SBS/AHT but were caused by a likely accidental “mild
    impact.”
    Based on this evidence, the trial court granted the defendant a new trial. It found
    that counsel’s original failure even to attempt to contact either Dr. Shuman or Dr. Spitz
    4
    Most notably, counsel failed to provide Hunter with certain critical case materials
    regarding injuries the child had suffered not long before her death, including: (1) a
    witness statement that the child had fallen off a trampoline, had struck her head, had
    briefly gone unconscious, and had been complaining of headaches in the days leading up
    to her death, and (2) the police report of the accident, which indicated that the child had
    been lethargic, had been vomiting, and had lost control of her bowels the day before she
    died.
    5
    Counsel explained at the Ginther hearing that he was not paid for pretrial preparation.
    5
    was objectively unreasonable, and that there was a reasonable probability of a different
    result at trial had counsel engaged his own medical expert.
    The Court of Appeals reversed, concluding that while there was no clear error in
    the trial court’s findings of fact, the trial court had abused its discretion in finding a
    constitutional violation because counsel’s “decision not to consult a second expert
    constituted trial strategy.” People v Ackley, unpublished opinion per curiam of the Court
    of Appeals, issued April 22, 2014 (Docket No. 318303), p 4. The court also held that
    even if counsel should have contacted an expert other than Hunter, no prejudice resulted
    in light of all the evidence against the defendant.
    The defendant sought leave to appeal in this Court. We heard oral argument on
    the application, limited to the issue of “whether the defendant was denied the effective
    assistance of counsel based on trial counsel’s failure to adequately investigate the
    possibility of obtaining expert testimony in support of the defense.” 6
    II. STANDARD OF REVIEW
    Whether the defendant received the effective assistance of counsel guaranteed him
    under the United States and Michigan Constitutions is a mixed question of fact and law.
    People v Trakhtenberg, 
    493 Mich. 38
    , 47; 826 NW2d 136 (2012), citing People v
    Armstrong, 
    490 Mich. 281
    , 289; 806 NW2d 676 (2011). This Court reviews for clear
    error the trial court’s findings of fact in this regard, and reviews de novo questions of
    constitutional law.

    .
    6
    People v Ackley, 
    497 Mich. 910
    (2014).
    6
    III. ANALYSIS
    Both the Michigan and United States Constitutions require that a criminal
    defendant be afforded the assistance of counsel in his or her defense. US Const, Am VI;
    Const 1963, art 1, § 20. To be constitutionally effective, counsel’s performance must
    meet an “objective standard of reasonableness.” 
    Trakhtenberg, 493 Mich. at 52
    . To show
    that this standard has not been met, a defendant must “overcome the strong presumption
    that counsel’s performance was born from a sound trial strategy.” 
    Id., citing Strickland
    v
    
    Washington, 466 U.S. at 689
    .       But “a court cannot insulate the review of counsel’s
    performance by calling it trial strategy”; counsel’s strategy must be sound, and the
    decisions as to it objectively reasonable. 
    Trakhtenberg, 493 Mich. at 52
    . Courts must
    determine whether the “strategic choices [were] made after less than complete
    investigation,” or if a “reasonable decision [made] particular investigations unnecessary.”
    
    Strickland, 466 U.S. at 690-691
    .
    To obtain relief for the denial of the effective assistance of counsel, the defendant
    must show that counsel’s performance fell short of this “objective standard of
    reasonableness” and that, but for counsel’s deficient performance, “there is a reasonable
    probability that the outcome of [the defendant’s trial] would have been different.”
    
    Trakhtenberg, 493 Mich. at 51
    . “A reasonable probability is a probability sufficient to
    undermine confidence in the outcome.” 
    Strickland, 466 U.S. at 694
    .
    A. COUNSEL’S PERFORMANCE
    Turning first to the performance prong of the Strickland analysis, we disagree with
    the Court of Appeals that counsel’s decision to consult only Dr. Hunter in preparation for
    trial was objectively reasonable. Rather, like the trial court, we conclude that counsel
    7
    performed deficiently by failing to investigate and attempt to secure an expert witness
    who could both testify in support of the defendant’s theory that the child’s injuries were
    caused by an accidental fall and prepare counsel to counter the prosecution’s expert
    medical testimony.
    As defense counsel was well aware before trial, the prosecution’s theory of the
    case was that the defendant intentionally caused the child’s unwitnessed injuries, a
    premise that it intended to prove with expert testimony. This testimony would require a
    response, and indeed, the court granted counsel funding to seek expert assistance of his
    own. Yet counsel contacted only Hunter, who repeatedly made clear that he credited the
    prosecution’s SBS/AHT theory and disagreed with the defense’s theory.              While
    conceding that the SBS/AHT diagnosis was not universally accepted within the medical
    community, Hunter explained to counsel that he “really d[id]n’t think [he] could help”
    the defendant because he was on the wrong side of this debate in his field.
    As a solution, he advised counsel to consult Dr. Shuman, who not only was on the
    defendant’s side of the SBS/AHT debate generally, but was significantly more likely to
    agree with the defendant’s claim that the child’s death in this case must have been
    accidental. Hunter even suggested that Dr. Shuman was more qualified because he had
    studied short falls extensively. Whereas Hunter was part of the group of experts who
    “don’t have a good model” to support the accidental fall theory, Dr. Shuman was
    “someone who has dug into the physics” and the “proposed models” of a short-fall injury.
    Hunter also characterized Dr. Shuman as a “man of science” and as “the best expert in
    these types of situations.” Yet counsel ignored this advice. He did not contact Dr.
    8
    Shuman or any other forensic pathologist with expertise in short falls, rendering Hunter
    his expert by default.
    Counsel did not have sufficient information to legitimate this “choice.” While an
    attorney’s selection of an expert witness may be a “paradigmatic example” of trial
    strategy, that is so only when it is made “after thorough investigation of [the] law and
    facts” in a case. Hinton v Alabama, ___ US ___; 
    134 S. Ct. 1081
    , 1088; 
    188 L. Ed. 2d 1
    (2014) (emphasis added). In this case, the record betrays no objectively reasonable
    explanation for counsel’s decision to confine his pursuit of expert assistance to Hunter, a
    self-proclaimed opponent of the very defense theory counsel was to employ at trial,
    despite Hunter’s referral to at least one other expert who could provide qualified and
    suitable assistance to the defendant. Nor is there any indication that counsel had the
    requisite familiarity with SBS/AHT or short-fall death theories to justify his settling on
    consulting only Hunter. To the contrary, counsel admittedly failed to consult any of the
    readily available journal articles on SBS/AHT and short-fall deaths, and did not
    otherwise educate himself or conduct any independent investigation of the medical issues
    at the center of the case, beyond his limited consultations with Hunter.               See
    
    Trakhtenberg, 493 Mich. at 54
    n 9 (noting that “a defense attorney may be deemed
    ineffective, in part, for failing to consult an expert when counsel had neither the
    education nor the experience necessary to evaluate the evidence and make for himself a
    reasonable, informed determination as to whether an expert should be consulted or called
    to the stand . . . .”) (quotation marks and citation omitted); Lindstadt v Keane, 239 F3d
    191, 202 (CA 2, 2001) (noting that counsel’s lack of familiarity with pertinent sexual
    abuse studies and failure to conduct any relevant research “hamstrung” his effort to
    9
    effectively cross-examine the prosecution’s expert witness); Holsomback v White, 133
    F3d 1382, 1387-1389 (CA 11, 1998) (holding that counsel’s failure to conduct an
    adequate investigation into medical evidence of sexual abuse was ineffective).
    We fail to see how counsel’s sparse efforts satisfied his “duty to make reasonable
    investigations or to make a reasonable decision that makes particular investigations
    unnecessary,” 
    Hinton, 134 S. Ct. at 1088
    , quoting 
    Strickland, 466 U.S. at 690-691
    ,
    especially in light of the prominent controversy within the medical community regarding
    the reliability of SBS/AHT diagnoses. See State v Edmunds, 308 Wis 2d 374, 391-392;
    746 NW2d 590 (2008) (holding that the “significant dispute” and “shift in the
    mainstream medical community” regarding SBS/AHT diagnoses since the defendant’s
    trial established a reasonable probability that a different result would be reached in a new
    trial, entitling the defendant to relief); Findley et al., Shaken Baby Syndrome, Abusive
    Head Trauma, and Actual Innocence: Getting It Right, 12 Hous J Health L & Policy 209,
    212 (2012) (explaining that, in SBS/AHT cases, “it is critical to assess the reliability of
    the diagnoses under the standards of evidence-based medicine”). In this case involving
    such “substantial contradiction in a given area of expertise,” counsel’s failure to engage
    “expert testimony rebutting the state’s expert testimony” and to become “versed in [the]
    technical subject matter” most critical to the case resulted in two things: a defense theory
    without objective, expert testimonial support, and a defense counsel insufficiently
    equipped to challenge the prosecution’s experts because he possessed only Dr. Hunter’s
    reluctant and admittedly ill-suited input as his guide. Knott v Mabry, 671 F2d 1208,
    1212-1213 (CA 8, 1982). This “constitute[d] a constitutional flaw in the representation”
    of the defendant, not reasonable strategy. 
    Id. at 1213.
    10
    In concluding otherwise, the Court of Appeals stressed that counsel is not required
    to shop for experts until finding one who will offer favorable testimony. We do not
    dispute that general proposition, but we fail to see its relevance here. In this case,
    counsel did no consultation at all beyond settling on the very first expert he encountered,
    despite the importance of expert medical testimony in the case and despite that expert’s
    specific recommendation to contact a different and more suitable expert.
    Nor can we agree with the Court of Appeals that Dr. Hunter’s comments regarding
    Dr. Shuman’s impartiality rendered it “reasonable for [counsel] to conclude that
    consulting a second expert would not be useful.” Ackley, unpub op at 4. Hunter’s
    warning that Dr. Shuman “would not buy into every story” or blindly accept the
    defendant’s theory is consistent with scientific integrity, is desirable, and is, indeed,
    advantageous in the context of expert testimony. But more importantly, Hunter’s core
    message on this very point was that counsel should engage Dr. Shuman, a qualified
    expert better suited to support the defendant’s theory. And without having done any
    research on SBS/AHT or short-fall injuries, or having made any contact with Dr.
    Shuman, counsel “ ‘was ill equipped to assess his credibility or persuasiveness as a
    witness’, or to evaluate and weigh the risks of putting him on the stand.” Towns v Smith,
    395 F3d 251, 260 (CA 6, 2005) (citation omitted). “To make a reasoned judgment about
    whether evidence is worth presenting, one must know what it says.” Couch v Booker,
    632 F3d 241, 246 (CA 6, 2011). Finally, as Dr. Spitz’s affidavit plainly demonstrates,
    Dr. Hunter’s advice to consult another expert was well founded.
    Accordingly, we conclude that counsel’s efforts to investigate and attempt to
    secure suitable expert assistance in preparing and presenting defendant’s case fell below
    11
    an objective standard of reasonableness. While the Court of Appeals may be correct that
    counsel’s deficiencies in this regard did not infect all of his conduct throughout the trial,
    see Ackley, unpub op at 6, the rest of his advocacy could not cure this crucial error. As
    the Supreme Court has said, “a single, serious error may support a claim of ineffective
    assistance of counsel.” Kimmelman v Morrison, 
    477 U.S. 365
    , 383; 
    106 S. Ct. 2574
    ; 91 L
    Ed 2d 305 (1986). Given the centrality of expert testimony to the prosecution’s proofs
    and the highly contested nature of the underlying medical issue, counsel committed
    exactly that kind of error by failing to consult an expert who could meaningfully assist
    him in advancing his theory of defense and in countering the prosecution’s theory of
    guilt.
    B. PREJUDICE
    We further conclude that, but for counsel’s deficient performance, “there is a
    reasonable probability that the outcome of [the defendant’s trial] would have been
    different.”

    . As set forth above,
    the defendant’s conviction turned on the jury’s assessment of the prosecution’s cause-of-
    death theory, which was advanced through the testimony of five experts, each of whom
    concluded that the child’s injuries were the result of some form of intentional abuse. The
    defendant’s own testimony and that of his lay character witnesses were extremely
    unlikely to counter this formidable expert testimony. Therefore, the absence of expert
    assistance in the defendant’s favor was critical. It prevented counsel from testing the
    soundness of the prosecution’s experts’ conclusions with his own expert testimony and
    with effective cross-examination. And again, as Dr. Spitz’s affidavit shows, such expert
    12
    assistance was available and would have provided the jury with another viable and
    impartial perspective on the facts of the case while contradicting the prosecution’s theory
    of how the child died.
    The Court of Appeals nonetheless found the prejudice from counsel’s deficient
    performance insufficient to warrant relief, given both the strength of the other, nonexpert
    evidence of the defendant’s guilt, and the sheer multitude of expert testimony the
    prosecution had marshaled in support of its position. We disagree times two.
    First, we fail to see particular strength in the prosecution’s nonexpert evidence,
    which was highly circumstantial, heavily contested, and far from dispositive of the issue
    of defendant’s guilt.    There was no explanation for the child’s injuries beyond the
    theories presented by the experts, and the prosecution produced no witnesses who
    testified that the defendant was ever abusive. In fact, some testimony supported the
    opposite conclusion; according to the child’s mother, the defendant’s disciplinary tactics
    were no different from her own, there was no indication that either of her daughters
    feared the defendant, there were alternative explanations for some of the child’s bruises
    and physical symptoms, 7 and the child willingly spent time with the defendant and called
    him “daddy.” 8 And while the prosecution claimed that the child began to exhibit health
    7
    The child’s mother attributed these bruises to the child’s diet and physical activity, and
    the prosecution’s forensic pathologist stated that the child was mildly anemic and that her
    bruising had no pattern indicating an object or a hand.
    8
    The Court of Appeals also cited the “peculiar” nature of the defendant’s actions on the
    day of the incident as an indication of his guilt. Specifically, the panel found significant
    the defendant’s failure to seek help from his neighbors after discovering the child on the
    floor, his attempt to revive her by pouring cold water over her, his decision to retrieve the
    family dog before fleeing the family’s home, and his decision to first go to his mother’s
    13
    issues around the time that the defendant entered her life, there was witness testimony to
    contradict this assertion, and the source and timing of these issues did not coincide with
    the defendant’s move into the family’s home or with his assumption of childcare duties. 9
    In short, our review of this nonexpert evidence makes plain why the prosecution chose to
    build its case primarily through the testimony of five experts, but it does little to weaken
    our conclusion that defense counsel’s failure to meaningfully engage and respond to this
    expert testimony created a reasonable probability of a different outcome at trial.
    Nor do we agree with the Court of Appeals that the sheer volume of the
    prosecution’s expert testimony rendered any such efforts by defense counsel futile. This
    reasoning presumptively prioritizes quantity over quality, and takes no account of the
    comparative persuasiveness of the “child abuse” and “accidental fall” theories at issue in
    house rather than the hospital. We do not disagree that the defendant’s behavior was
    relevant and, furthermore, that a jury might consider it evidence of guilt. The probability
    that the jury would do so, however, might be said to make it even more critical that
    counsel counter the expert-endorsed theory of his client’s guilt with an expert-endorsed
    theory of his client’s innocence. Had counsel provided a different lens through which to
    view his client’s behavior, those same “peculiar” actions by the defendant might have
    instead been perceived as the missteps of a panicked, but nonetheless innocent, caretaker.

    For example, the Court of Appeals cited the child’s hair loss as one physical
    manifestation of abuse, but according to her mother, her hair began thinning before the
    defendant moved in with the family. In any event, doctors diagnosed it as an infection,
    not a stress-related issue. The child’s regression in toilet training was also emphasized as
    evidence of abuse.         Yet a report from the child’s pediatrician attributed her
    developmental progress, including the fact that she had even begun her toilet training, to
    the defendant’s care. Unfortunately, defense counsel never called the child’s pediatrician
    to testify, though these facts could have refuted the prosecution’s allegations that the
    defendant had been physically abusing the child over a sustained period. Counsel’s only
    “explanation” for this omission was that this credible counter-evidence was not needed
    because it did not fit in with his “trial strategy” of attributing the child’s blunt force
    trauma to a fall from the bed.
    14
    the case.   It also places the defendant in a near-impossible position, whereby the
    prejudice caused by his counsel’s error is effectively used to foreclose his claim of relief
    based upon that very error. The prosecution’s voluminous expert testimony made the
    need for an effective response by defense counsel particularly apparent and strong, and it
    rendered counsel’s failure to offer expert testimony particularly glaring and harmful to
    the defendant. Because of counsel’s omissions and the resulting absence of suitable
    expert assistance, the prosecution’s expert testimony appeared uncontested and
    overwhelming. Contrary to the Court of Appeals, we believe this consequence militates
    in favor of, rather than against, the defendant’s claim of relief.
    The Court of Appeals’ analysis thus vastly underestimated the value of expert
    assistance to the defense and the impact of its absence, ignoring the fact that in a
    SBS/AHT case such as this, where there is “no victim who can provide an account, no
    eyewitness, no corroborative physical evidence and no apparent motive to kill,” the
    expert “is the case . . . .”   Tuerkheimer, The Next Innocence Project: Shaken Baby
    Syndrome and the Criminal Courts, 87 Wash U L Rev 1, 27 (emphasis added). Here,
    expert testimony was not only integral to the prosecution’s ability to supply a narrative of
    the defendant’s guilt, it was likewise integral to the defendant’s ability to counter that
    narrative and supply his own. Had an impartial, scientifically trained expert corroborated
    the defendant’s theory, the defendant’s account of the child’s death would not have
    existed in a vacuum of his own self-interest. While we cannot say that a battle of the
    experts would have ensured the defendant’s acquittal, counsel’s failure to prepare or
    show up for the battle sufficiently “undermine[s our] confidence in the outcome” of this
    case to entitle the defendant to relief.

    IV. CONCLUSION
    For the reasons set forth above, we conclude that the defendant is entitled to a new
    trial because of his counsel’s constitutionally ineffective failure to investigate adequately
    and to attempt to secure appropriate expert assistance in the preparation and presentation
    of his defense. Accordingly, we reverse the judgment of the Court of Appeals, vacate the
    defendant’s convictions, and remand to the Calhoun County Circuit Court for further
    proceedings consistent with this opinion.
