Overview
- Closing arguments began Thursday after more than 20 days of testimony in the Plymouth County trial, and jurors were dismissed so the judge can give final instructions before deliberations.
- Prosecutors say evidence from the crime scene, autopsies and phone and wearable data shows Clancy planned the killings and sent her then‑husband out of the house before the deaths.
- The defense argued Clancy was suffering severe postpartum psychosis combined with bipolar disorder and recent medication changes, and it relied on psychiatric experts to say she lacked criminal responsibility.
- Judge William Sullivan told each side they would get one hour for closing statements and said he will instruct jurors on lesser charges including manslaughter as possible verdicts.
- The trial’s outcome will determine whether Clancy is sentenced to life without parole or committed to a state psychiatric hospital, and it has intensified scrutiny of perinatal mental‑health care, prescribing practices and related civil claims.
