Heidi Ann Anfinson v. State of Iowa

Summary

The Supreme Court of Iowa held that trial counsel provided ineffective assistance by failing to investigate and present evidence of Heidi Anfinson's postpartum depression in support of her accidental-death defense. The court found a reasonable probability that this evidence could have affected the trial outcome and ordered a new trial. The court vacated the court of appeals decision, reversed the district court judgment, and remanded the case.

Holdings

1. Trial counsel provided ineffective assistance by failing to reasonably investigate Anfinson's postpartum depression and failing to present available evidence connecting that condition to the conduct relied upon by the State as evidence of criminal culpability. There was a reasonable probability of a different outcome had the evidence been developed and presented.
2. Anfinson failed to prove that counsel breached an essential duty by failing to investigate or present an insanity defense based on postpartum depression.
3. Anfinson failed to prove prejudice from counsel's failure to present a diminished-responsibility defense because diminished responsibility is limited to negating specific intent and is unavailable to a defendant convicted of second-degree murder, which requires malice aforethought rather than specific intent to kill.
4. Evidence of Anfinson's mental condition was not rendered inadmissible merely because she did not timely assert insanity or diminished responsibility, where the evidence was offered for the limited purpose of supporting the accidental-death theory rather than proving insanity or inability to form specific intent.

Questions Presented

1. Whether trial counsel rendered ineffective assistance by failing to investigate and present evidence of Anfinson's postpartum depression in support of an accidental-death defense.
2. Whether trial counsel was ineffective for failing to investigate or present an insanity defense based on postpartum depression.
3. Whether trial counsel was ineffective for failing to present a diminished-responsibility defense based on postpartum depression.
4. Whether evidence of Anfinson's mental condition could be admitted for the limited purpose of supporting the accidental-death theory despite the absence of timely notice of insanity or diminished responsibility defenses.
