Jury Weighs Lindsay Clancy Insanity Plea in 3-Child Murders as Postpartum Psychosis Defense Faces Legal Test

Summary
Massachusetts jurors are nearing a decision on whether Lindsay Clancy was legally insane when she killed her three children on Jan. 24, 2023, a verdict that will determine prison or psychiatric commitment.
Clancy's lawyers say postpartum psychosis drove the killings after months of spiraling mental illness, citing repeated pleas for help, a brief hospitalization and 13 prescribed medications.
Prosecutors argue she still acted with intent, pointing to evidence that she appeared organized and communicative and sent her husband on an errand before the killings.
Massachusetts law allows a not-criminally-responsible verdict if mental illness left a defendant unable to appreciate wrongfulness or conform conduct to law, a narrower test than clinical diagnosis alone.
An insanity acquittal would not mean release: Clancy would enter a state psychiatric facility, and successful insanity pleas often result in longer state custody than criminal convictions.
