    HECHT, Justice.
    Heidi Anfinson was convicted of second-degree murder for the
    drowning death of her infant son. In this postconviction relief action, we
    consider whether trial counsel rendered prejudicial ineffective assistance
    in failing to sufficiently inquire into and present evidence of Anfinson’s
    postpartum depression in furtherance of her defense theory that the
    child’s death was accidental.       We conclude Anfinson’s trial counsel
    provided ineffective assistance that resulted in prejudice.      Accordingly,
    we reverse Anfinson’s conviction and remand this case to the district
    court for a new trial.
    I.     Factual and Procedural Background.
    Heidi Anfinson gave birth to a son, Jacob, on September 5, 1998.
    Fifteen days after his birth, Jacob went missing while in Anfinson’s care.
    Jacob’s father contacted the police, who began searching for the child.
    While officers were searching for Jacob, Anfinson and her husband were
    transported to the police station. Anfinson told the officers that while
    bathing Jacob, she left the room to use the telephone; and when she
    returned, she discovered Jacob had drowned.           Anfinson led police to
    Saylorville Lake, where they discovered Jacob’s body submerged under
    rocks in shallow water. During a later interview with police, Anfinson
    stated she “freaked” when she found Jacob’s dead body in the bath
    water, put it in the car, took it to the lake, and placed it in the water.
    The State charged Anfinson with first-degree murder and child
    endangerment. Iowa Code §§ 707.1, .2, 726.6(1), .6(2) (1997). Anfinson
    pled not guilty and the case proceeded to trial. The first trial resulted in
    a mistrial as the jury was unable to reach a unanimous decision. In a
    second trial involving the same charges, the jury convicted Anfinson of
    second-degree murder.       
    Id. § 707.3.
       On direct appeal, the court of
    3
    appeals affirmed the conviction. State v. Anfinson, No. 00-0511 (Iowa Ct.
    App. July 3, 2002).
    Anfinson filed an application for postconviction relief alleging
    ineffective assistance of counsel.            She presented evidence tending to
    prove her trial counsel summarily dismissed the notion of raising
    insanity or diminished capacity defenses despite evidence she was
    suffering from severe postpartum depression at the time of Jacob’s
    death. She also asserted trial counsel, who chose to present the defense
    theory that Jacob died accidentally, was ineffective in failing to present
    evidence of her postpartum depression in furtherance of that theory.
    Anfinson further contended trial counsel was ineffective in failing to
    object to the testimony of the investigating officers who described
    Anfinson’s lack of emotion shown during the interview at the police
    station when she denied knowledge of Jacob’s whereabouts.1
    In a detailed ruling, the district court dismissed Anfinson’s
    application.     The court concluded trial counsel breached an essential
    duty by failing to investigate Anfinson’s mental and physical condition,
    but reasoned Anfinson was not entitled to relief because she failed to
    prove the requisite prejudice resulting from the breach. The court also
    found Anfinson failed to prove prejudice resulting from the admission of
    the officers’ testimony describing Anfinson’s lack of emotion during
    questioning. The court of appeals affirmed the dismissal of the petition,
    and we granted further review.
    1Before  the district court and court of appeals Anfinson raised additional claims
    of ineffectiveness. Our opinion on further review is confined in this case to the grounds
    specifically asserted in her application for further review.
    4
    II.     Scope of Review.
    We review ineffective-assistance-of-counsel claims de novo. State
    v. Bearse, 
    748 N.W.2d 211
    , 214 (Iowa 2008).               To establish ineffective
    assistance of counsel, a claimant must demonstrate by a preponderance
    of the evidence “(1) his trial counsel failed to perform an essential duty,
    and (2) this failure resulted in prejudice.” State v. Straw, 
    709 N.W.2d 128
    , 133 (Iowa 2006); accord Strickland v. Washington, 
    466 U.S. 668
    ,
    687–88, 694, 
    104 S. Ct. 2052
    , 2064–65, 2068, 
    80 L. Ed. 2d 674
    , 698
    (1984).       We may affirm the district court’s rejection of an ineffective-
    assistance-of-counsel claim if either element is lacking. State v. Greene,
    
    592 N.W.2d 24
    , 29 (Iowa 1999). To establish prejudice, a claimant must
    demonstrate “ ‘there is a reasonable probability that, but for the
    counsel’s unprofessional errors, the result of the proceeding would have
    been different.’ ” State v. Reynolds, 
    746 N.W.2d 837
    , 845 (Iowa 2008)
    (quoting 
    Strickland, 466 U.S. at 694
    , 104 S. Ct. at 
    2068, 80 L. Ed. 2d at 698
    ).     The probability of a different result must be “ ‘sufficient to
    undermine confidence in the outcome.’ ” 
    Id. III. Discussion.
    A. Failure to Investigate and Assert Defenses Based on
    Postpartum Depression.            On our de novo review, we find that trial
    counsel was aware of the probability Anfinson suffered from postpartum
    depression after Jacob’s birth and categorically rejected any suggestion
    that this condition be explored in her defense.                Anfinson’s sisters
    observed Anfinson behaving strangely soon after Jacob was born on
    September 5, 1998.          While attending a baby shower, they observed
    numerous         “sores”   on   Anfinson’s   legs   and   perceived   her   to   be
    5
    “exhausted,” “wooden,” and “unjoyful.”2 Anfinson appeared to be afraid
    to handle Jacob.
    On September 22, 1998, after trial counsel undertook Anfinson’s
    defense, trial counsel and several of Anfinson’s family members were
    present when Anfinson was released on bail.                 As they left the jail, an
    unidentified woman approached.                  The woman disclosed she had
    experienced postpartum depression, claimed she knew what Anfinson
    was going through, and attempted to hand an envelope to one of
    Anfinson’s family members.            Trial counsel snatched the envelope and
    proclaimed he “didn’t want to hear any talk of postpartum depression.”
    He was quoted in a newspaper article published the next day, suggesting
    postpartum depression was not a factor in the baby’s accidental death.3
    Although Anfinson was hospitalized on September 26, 1998 and
    medicated for depression, suicidal ideation, and panic attacks, trial
    counsel failed to request or obtain copies of Anfinson’s medical records.4
    He also failed to conduct an investigation which would have divulged
    2Anfinson  initially told her sisters the “sores” were caused by mosquito bites, but
    later disclosed they were caused by self-mutilation as she plucked hairs from her legs
    and pubic area.
    3Counsel   made this public pronouncement without the benefit of a reasonable
    investigation of Anfinson’s mental health. He described himself in the postconviction
    proceeding as a “media lawyer” and characterized his comments quoted in the
    newspaper article as an effort to ethically “manage” and “balance” the news in
    furtherance of Anfinson’s accidental death defense. Counsel testified he “didn’t want
    the public to even think of postpartum depression, because postpartum depression
    means you deliberately killed the baby.”
    4The   records disclose the hospital staff assigned to Anfinson a GAF (Global
    Assessment Functioning) of ten at the time she was admitted to the hospital. Although
    this rating is based on a medical professional’s subjective rating, it suggests Anfinson
    was functioning at a very low level at the time of admission. Trial counsel explained he
    did not request copies of the hospital records because Anfinson represented she was
    bonded with the baby, claimed she was a good mother, and denied she was depressed.
    He consulted no psychiatrist or psychologist on the subject of Anfinson’s mental state.
    6
    Anfinson experienced prior episodes of depression after she gave birth
    and consented to the adoption of her first child in 1980, and again
    following an abortion in 1985.
    Additional evidence supports our finding trial counsel rejected from
    the outset the notion evidence of Anfinson’s mental condition might be
    relevant to her defense. After Anfinson’s discharge from the hospital, she
    was treated by a grief counselor for several months. When the counselor
    called to discuss Anfinson’s mental state, trial counsel was dismissive of
    her opinion that Anfinson had exhibited symptoms consistent with
    postpartum depression.
    Members of Anfinson’s family also attempted on several occasions
    to communicate to trial counsel their concerns about Anfinson’s mental
    state.    Anfinson’s father, who paid trial counsel’s fees and litigation
    expenses, urged trial counsel to approve, and offered to pay for, a mental
    evaluation of Anfinson at the Menninger Clinic in Topeka, Kansas.
    Counsel rejected the idea, again affirming postpartum depression would
    play no part in the defense.5          When Anfinson’s sister and husband
    attempted to speak to trial counsel about their observations of Anfinson’s
    mental state, he cautioned them against making comments to the press
    about postpartum depression and reminded them the defenses of
    insanity and diminished capacity would not be pursued.
    Anfinson contends the evidence of her severe depression was
    essential    not   only   to   prove   potential   insanity   and   diminished
    responsibility defenses which were summarily and improvidently rejected
    by her trial counsel, but also to support the accidental death defense
    counsel presented unsuccessfully to the jury. The State contends trial
    5Trial counsel told Anfinson’s family he opposed the request for a mental
    evaluation on the ground it would be “fuel for the prosecution.”
    7
    counsel breached no duty in rejecting insanity and diminished capacity
    defenses, and his assertion of the accidental death theory of defense was
    based on reasonable strategic considerations.
    Generally, “ineffective assistance is more likely to be established
    when the alleged actions or inactions of counsel are attributed to a lack
    of diligence as opposed to the exercise of judgment.” Ledezma v. State,
    
    626 N.W.2d 134
    , 142 (Iowa 2001).           “[M]ere mistakes in judgment
    normally do not rise to the level of ineffective assistance of counsel.” 
    Id. at 143.
    [C]laims of ineffective assistance involving tactical or
    strategic decisions of counsel must be examined in light of
    all the circumstances to ascertain whether the actions were
    a product of tactics or inattention to the responsibilities of
    an attorney guaranteed a defendant under the Sixth
    Amendment.
    
    Id. However, not
    all tactical or strategic decisions shelter an attorney
    from a claim of ineffectiveness. 
    Id. While strategic
    decisions made after “thorough investigation
    of law and facts relevant to plausible options are virtually
    unchallengeable,” strategic decisions made after a “less than
    complete investigation” must be based on reasonable
    professional judgments which support the particular level of
    investigation conducted.
    
    Id. (quoting Strickland,
    466 U.S. at 
    690–91, 104 S. Ct. at 2066
    , 80
    L. Ed. 2d at 695).
    Moreover, reasonable strategic considerations may justify the
    rejection of one theory of defense in favor of another theory reasonably
    perceived by counsel to be in the accused’s best interest. See Tollett v.
    Henderson, 
    411 U.S. 258
    , 268, 
    93 S. Ct. 1602
    , 1608, 
    36 L. Ed. 2d 235
    ,
    244 (1973); State v. Wilkens, 
    346 N.W.2d 16
    , 19 (Iowa 1984) (counsel not
    ineffective in making sound tactical decision to emphasize self defense
    rather than diminished capacity, and staying that course in preparing
    8
    and presenting case to jury). The postconviction court must not “assume
    the role of Monday morning quarterback in condemning counsel’s
    judgment in choosing between what are frequently equally hazardous
    options available to him.” State v. Newman, 
    326 N.W.2d 788
    , 795 (Iowa
    1982).     The real issue is not whether defense counsel’s actions were
    successful, but whether they were “justifiable.”     Pettes v. State, 
    418 N.W.2d 53
    , 56–57 (Iowa 1988).
    Keeping these principles in mind, we consider whether Anfinson
    met her burden to prove trial counsel provided ineffective assistance in
    failing to investigate and present evidence of her mental condition in
    furtherance of the potential defenses he rejected and the one defense he
    actually presented.
    1.      Insanity. The legal standard for an insanity defense in Iowa
    is codified at section 701.4 of the Iowa Code:
    A person shall not be convicted of a crime if at the time the
    crime is committed the person suffers from such a diseased
    or deranged condition of the mind as to render the person
    incapable of knowing the nature and quality of the act the
    person is committing or incapable of distinguishing between
    right and wrong in relation to that act. Insanity need not
    exist for any specific length of time before or after the
    commission of the alleged criminal act. If the defense of
    insanity is raised, the defendant must prove by a
    preponderance of the evidence that the defendant at the time
    of the crime suffered from such a deranged condition of the
    mind as to render the defendant incapable of knowing the
    nature and quality of the act the defendant was committing
    or was incapable of distinguishing between right and wrong
    in relation to the act.
    We concur with the district court that Anfinson has failed to
    demonstrate a reasonable probability of the success, or even viability, of
    an insanity defense based on postpartum depression.        Based on her
    responses to police questioning and a review of a report of a
    psychological evaluation conducted days after Jacob’s death, the State’s
    9
    mental health expert testified in the postconviction trial that at the time
    of Jacob’s death Anfinson was not suffering from a mental disease or
    defect of the nature that would have supported an insanity defense.
    Even the mental health expert retained by Anfinson in connection with
    this postconviction action did not opine Anfinson was insane at the time
    of the child’s death. We conclude Anfinson has failed to prove her trial
    counsel breached a duty in failing to investigate or present an insanity
    defense based on postpartum depression.
    2.     Diminished responsibility.         In the alternative, Anfinson
    contends evidence of her postpartum depression would have supported a
    diminished      responsibility    defense.       The   doctrine     of   diminished
    responsibility has been recognized in Iowa as a matter of common law.6
    State v. Gramenz, 
    256 Iowa 134
    , 138–42, 
    126 N.W.2d 285
    , 288–90
    (1964). “[D]iminished responsibility may be offered as a defense where
    an accused, because of a limited capacity to think, is unable to form a
    necessary criminal intent.” State v. Collins, 
    305 N.W.2d 434
    , 436 (Iowa
    1981).      The diminished responsibility defense allows a defendant to
    negate the specific intent element of a crime by demonstrating due to
    some mental defect she did not have the capacity to form that specific
    intent. 
    Id. at 437.
    Evidence of diminished responsibility may not, however, negate
    general criminal intent, and is therefore not a defense to crimes which do
    6We have alternatively described the common law concept of decreasing a legally
    sane individual’s criminal liability on the basis of a mental defect as a defense of
    “diminished capacity” and “diminished responsibility.” See, e.g., State v. Decker, 
    744 N.W.2d 346
    , 350 (Iowa 2008) (diminished capacity); State v. Duncan, 
    710 N.W.2d 34
    , 36
    (Iowa 2006) (diminished responsibility). Iowa Rule of Criminal Procedure 2.11(11)(b),
    the defense notice requirement, refers to notice of intent to rely upon the defense of
    diminished responsibility. In the interest of remaining consistent with our rules of
    procedure, we will use the term “diminished responsibility” in this opinion.
    10
    not require proof of specific intent.    State v. McVey, 
    376 N.W.2d 585
    ,
    586–87 (Iowa 1985) (evidence of mental unsoundness establishing lack of
    capacity to form the requisite criminal intent was not relevant in
    prosecution for theft perpetrated by exercising control over stolen
    property, a general intent crime); Veverka v. Cash, 
    318 N.W.2d 447
    , 449
    (Iowa 1982) (diminished capacity not a defense to felony murder
    accomplished by arson); 
    Gramenz, 256 Iowa at 142
    , 126 N.W.2d at 290
    (evidence of diminished capacity not relevant to issues of malice
    aforethought and general criminal intent). But see Hendershott v. People,
    
    653 P.2d 385
    , 393–94 (Colo. 1982) (holding reliable and relevant
    evidence of mental impairment may be presented to negate mens rea for
    crimes not involving a specific intent element). In McVey, we concluded
    the General Assembly, by statutorily recognizing the insanity defense,
    has limited the legal relevance of evidence of mental impairment to
    general intent crimes:
    In formulating the insanity defense the legislature
    defined limits upon the effect of evidence of mental disease
    or defect relating to criminal culpability generally. This court
    earlier drew the same line at common law in the Gramenz
    case. It would undercut the legislative policy inherent in the
    insanity defense for this court to extend the defense of
    diminished responsibility.
    Insanity and mens rea are legal concepts without
    psychiatric counterparts. As legal concepts they are used to
    establish limits to legal culpability. The extent to which
    evidence of mental impairment will be permitted to affect
    criminal responsibility is therefore a legal question. The
    argument that evidence of mental impairment should be
    received because it bears on the mens rea of an offense
    presupposes that the mens rea requirement has a legal
    meaning which makes the evidence from the psychological
    model relevant. See, e.g., 1 P. Robinson, Criminal Law
    Defenses § 64(c) at 283 (1984) (“the issue . . . is a complex
    one that is tied to one’s theory of the nature of the mens rea
    requirements for criminal offenses”).
    11
    . . . In practical terms a court’s refusal to recognize
    the relevancy of evidence of mental impairment short of legal
    insanity results from the court’s understanding of the
    legislative intention concerning the blameworthiness of the
    defendant’s conduct. To the extent evidence of mental
    impairment that does not meet the legal insanity standard
    permits an accused to avoid responsibility for otherwise
    culpable conduct, the policy inherent in the insanity defense
    is undermined. See W. LaFave and A. Scott, Handbook on
    Criminal Law § 42 at 331-32 (1972).
    
    McVey, 376 N.W.2d at 587
    –88. We therefore concluded the legislature
    intended to preclude evidence of mental impairment which falls short of
    insanity “in cases requiring proof only of guilty knowledge or general
    criminal intent accompanying a prohibited act.” 
    Id. at 588.
    Although she was charged with first-degree murder, Anfinson was
    ultimately convicted of second-degree murder.     To convict Anfinson of
    second-degree murder, the State was required to prove Anfinson
    drowned Jacob with malice aforethought. See Iowa Code § 707.3. The
    State was not required to prove Anfinson acted with a specific intent to
    kill Jacob.   Iowa Code § 707.3; State v. Artzer, 
    609 N.W.2d 526
    , 531
    (Iowa 2000). As we explained in Gramenz, malice aforethought is not a
    specific intent mens rea:
    While malice aforethought is the specific state of mind
    necessary to convict of murder, it is far different from the
    specific intent which is a necessary element of murder in the
    first degree. It may be express or implied from the acts and
    conduct of defendant.
    ...
    It appears . . . that testimony sufficient to establish
    defendant’s lack of mental capacity to have malice
    aforethought would also be sufficient to satisfy the
    requirements of the right and wrong test and entitle
    defendant to an acquittal on a plea of insanity rather than a
    reduction of the sentence . . . .
    
    Gramenz, 256 Iowa at 142
    , 126 N.W.2d at 290.           Thus, in Iowa, a
    defendant may only attempt to negate malice aforethought with evidence
    12
    of insanity. 
    Artzer, 609 N.W.2d at 531
    (“The defense[] of . . . diminished
    capacity [is] not available to a defendant charged with second-degree
    murder. This is because . . . diminished capacity [is] only [a] defense[] to
    the specific intent element of a crime.”       (Citations omitted.)).   We
    conclude Anfinson has failed to prove prejudice resulting from counsel’s
    failure to present a diminished responsibility defense because she was
    not convicted of first-degree murder and evidence supporting such a
    defense was not relevant to any element of the second-degree murder
    charge of which she was convicted.
    3.    Accidental death.     Although the evidence of Anfinson’s
    postpartum depression could not have constituted a defense to the
    second-degree murder charge under our case law, Anfinson alternatively
    contends her trial counsel was nonetheless ineffective in failing to offer
    such evidence in furtherance of her accidental death defense.           We
    emphasize Anfinson’s contention here is not that counsel was ineffective
    for failing to offer evidence of depression to respond to the State’s
    evidence tending to prove criminal mens rea. As she did not give notice
    of her intent to claim insanity or diminished capacity, evidence of
    Anfinson’s compromised mental state was not admissible at trial to
    support those defenses.     She asserts, instead, her accidental death
    defense was severely prejudiced by counsel’s failure to adduce and
    present expert testimony diagnosing her depression and placing three
    crucial and troublesome aspects of her conduct in a medical and
    noncriminal context.
    Anfinson claims evidence of her depression should have been
    developed and offered in the criminal trial for three purposes which were
    crucial to a successful outcome of the accidental death defense. If the
    defense was to have any chance of success, it had to supply for the fact-
    13
    finder a plausible explanation of (1) why Anfinson was so distracted and
    inattentive on September 20, 1998 that she left her two-week-old baby
    unattended in bath water; (2) why she behaved irrationally in
    subsequently taking Jacob’s body to the lake, burying it under rocks,
    returning to her home, and going to sleep; and (3) why her affect was flat
    and emotionless later that same day when she was questioned by
    investigators about the child’s disappearance. There was ample evidence
    of Anfinson’s postpartum depression available to trial counsel if he had
    chosen to undertake the most rudimentary inquiry. He chose instead to
    rebuff all attempts made by Anfinson’s family members and her grief
    counselor to educate him. He closed not only his ears, but also his eyes
    as he neglected to obtain medical records evidencing Anfinson’s mental
    state.
    The defense of “accidents happen” chosen and presented by trial
    counsel was highly unlikely to result in an acquittal if the three most
    troublesome      aspects    of   Anfinson’s     conduct      suggesting     criminal
    culpability were left unexplained. Expert and lay testimony presented by
    Anfinson at the postconviction trial clearly suggests trial counsel could
    have developed strong evidence detailing the nature and extent of
    Anfinson’s depression and provided an explanation for her bizarre
    behavior on the day of Jacob’s death.7
    The State asserts trial counsel’s decision to eschew a defense
    based on Anfinson’s mental state was a reasonable strategic choice. In
    7Anfinson’s mental health expert testified that the bizarre and unusual
    circumstances surrounding Jacob’s death “cried out” for a psychiatric evaluation. In
    particular, the expert noted an evaluation is indicated “in a situation where somebody
    for unexplained reasons is suspected of harming an infant.” Moreover, the expert
    opined Anfinson’s mental state could have provided an explanation of why she exhibited
    poor judgment, panicked, and put the child in the lake.
    14
    support of this proposition, we are reminded both trial counsel and the
    State’s expert witness viewed defenses based on Anfinson’s compromised
    mental state (insanity and diminished responsibility) as “defenses of last
    resort” and inconsistent with the accidental death theory presented to
    both juries.     Even though insanity and diminished responsibility
    defenses may have been incompatible with Anfinson’s accidental death
    theory, evidence of the defendant’s mental state was not incompatible
    with the notion that Jacob’s death was accidental and, in fact, would
    have   supported    her    claim   that    the   drowning   was   due   to   her
    inattentiveness. Even if we were to accept as sound for purposes of our
    analysis trial counsel’s assessment that insanity and diminished
    responsibility defenses are rarely successful, the decision to ignore
    evidence of Anfinson’s compromised mental state was not a reasonable
    professional judgment excusing an investigation of the extent to which
    that mental state supported the defense theory of accidental death.
    The State further contends trial counsel’s failure to investigate
    Anfinson’s mental state and its relevance to the accidental death theory
    was reasonable given Anfinson’s representation to counsel in November
    1998 that she was experiencing “situational depression” or “something
    like that.”    Any failure to investigate whether Anfinson experienced
    postpartum depression is further justified, the State claims, by
    Anfinson’s failure to tell trial counsel she had lost weight late in the
    pregnancy, and her failure to disclose the history of sleep disturbance
    and self-mutilation.      Indeed, trial counsel claims when he met with
    Anfinson he found her to consistently exhibit appropriate judgment, the
    ability to communicate, and the capacity to assist in her defense.
    We conclude, as did the district court, that trial counsel’s strategic
    decision to renounce evidence of his client’s compromised mental state
    15
    after a less than complete investigation was not based on reasonable
    professional judgment. Furthermore, our confidence in the outcome of
    Anfinson’s criminal trial is shaken by trial counsel’s failure to reasonably
    investigate and prove his client’s mental condition in furtherance of the
    accidental death defense.     We find a reasonable probability that if a
    reasonable investigation had been undertaken, evidence would have been
    developed and presented at trial tending to establish Anfinson’s conduct
    from the time of Jacob’s birth until his death was profoundly affected by
    postpartum depression. We find a reasonable probability of a different
    outcome if trial counsel had developed and presented expert testimony
    diagnosing Anfinson’s severe postpartum depression and connecting it
    with her bizarre behavior in furtherance of the accidental death defense.
    We are mindful of the deference owed by postconviction courts to
    counsel’s strategic choices. Deference for such choices is not unlimited,
    however, and it will not be stretched to deny Anfinson a new trial under
    the circumstances presented here.
    We reject the State’s assertion evidence tending to prove Anfinson
    suffered from postpartum depression on the day of Jacob’s death was not
    admissible for any purpose because she chose not to assert either an
    insanity or a diminished capacity defense. Although the State is correct
    that the law precludes a defendant from asserting those defenses if she
    fails to give timely notice of them consistent with Iowa Rule of Criminal
    Procedure   2.11(11)(b)(1),   we   are    not   persuaded   evidence   of   the
    defendant’s mental condition is inadmissible for the limited purpose
    advanced by Anfinson. We conclude such a limited use of evidence of
    Anfinson’s mental state will not undercut the proper limits of mental
    defenses prescribed by the General Assembly and observed by this court
    in McVey.    A proper limiting instruction would suffice to clarify that
    16
    Anfinson’s purpose in offering such evidence is not in furtherance of a
    claim she was insane or incapable of forming a specific intent at the time
    of Jacob’s death, but rather to support her theory Jacob’s death was
    accidental. See Iowa R. Evid. 5.105.
    IV.   Conclusion.
    Anfinson has met her burden to prove trial counsel rendered
    prejudicial ineffective assistance by failing to investigate and present
    evidence of Anfinson’s depression in furtherance of the accidental death
    defense. As we conclude she is entitled to a new trial for this reason, we
    need not address the other issues raised on appeal.
