Overview
- Jury selection started July 20, 2026, in Plymouth Superior Court and judges expect to seat 18 jurors, including alternates, before the trial proceeds.
- Prosecutors say Clancy planned the killings by sending her husband out and strangling the three children with exercise bands, and they will play the husband’s 911 call, show crime‑scene photos, and bring jurors to the family home.
- The defense has acknowledged Clancy caused the deaths but argues severe postpartum psychosis and overmedication left her unable to understand or control her actions, and it plans to mount an insanity (lack‑of‑criminal‑responsibility) defense.
- Pretrial rulings by Judge William Sullivan narrowed testimony for the defense by excluding lay accounts from other women about postpartum experiences and some late witness additions while allowing the 911 call and a site visit to be used by prosecutors.
- If convicted of first‑degree murder Clancy faces life without parole, but a finding of not criminally responsible would likely lead to involuntary commitment to a state psychiatric hospital, and the case is renewing scrutiny of perinatal mental‑health care and medication management.
