Lindsay Clancy Trial: Prosecution's Psychologist Says She Knew Right From Wrong

Lindsay Clancy, the 34-year-old Duxbury, Massachusetts mother accused of strangling her three children — 5-year-old Cora, 3-year-old Dawson, and 7-month-old Callan — with exercise resistance bands inside the family's Summer Street home on January 24, 2023, is back in Plymouth Superior Court, and this week the prosecution brought out its heaviest hitter yet. Clancy faces three counts of murder and three counts of strangulation. She's pleaded not guilty, and defense attorney Kevin Reddington is running an insanity defense built on severe postpartum psychosis and psychiatric overmedication. Monday got messy before the end. Reddington moved for a mistrial after "mortal sin" came up for the second time from the prosecution's side. Judge William Sullivan said no, but told jurors to strike anything about sin or religiosity from Dr. Kirk Heilbrun's testimony — and made it clear the prosecution needed to keep their own witness on a shorter leash. When Heilbrun, a forensic psychologist, came back Tuesday, he laid out a different diagnosis than the defense wants jurors thinking about: bipolar II, yes, but what happened that day looks like a serious suicide attempt paired with altruistic filicide — not psychosis. He testified Clancy understood the legality of what she was doing and could have stopped herself. His opinion: criminally responsible. He also flagged something jurors probably won't forget — Clancy calling her husband back mid-crisis — and said that doesn't read as self-centered, it reads as a mother already grieving. After the killings, Clancy allegedly attempted suicide by jumping from a second-story window and is now paralyzed from the waist down. Husband Patrick Clancy was out running errands at the time and has since relocated to Manhattan.
