Lindsay Clancy Trial: Blood Spatter and Toxicology Testimony Just Got Real

Testimony in the Lindsay Clancy murder trial moved from the courtroom's emotional register into its clinical one this week, and somehow that was harder to sit through. Clancy, 34, of Duxbury, Massachusetts, is 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. She faces three counts of murder and three counts of strangulation, has pleaded not guilty, and her attorney, Kevin Reddington, is mounting an insanity defense built around severe postpartum psychosis and psychiatric overmedication.

Plymouth Superior Court Judge William F. Sullivan opened the afternoon by reading stipulations both sides had already agreed to on the children's toxicology results — the kind of procedural moment that saves the jury a fight over numbers neither side disputes. Then came the science. Alicia Zimmermann of the Massachusetts State Police Crime Lab walked the jury through how toxicology testing actually works when the person who died is a child, a process built for adults and adapted, carefully, for the smallest bodies imaginable. After her came Sherri Crook, who supervises the State Police Crime Scene Response unit, breaking down blood spatter analysis — the differences between spatter, pooling, and smearing — and applying that framework directly to what investigators found inside the Clancy home.

None of it was theatrical. All of it mattered. This is what a strangulation case actually runs on: not gut feelings, but lab reports and pattern analysis that either back up the state's timeline or don't. Prosecutors Jennifer Sprague and Shanan Buckingham are building toward showing Clancy understood what she was doing. The defense needs the psychiatric picture to swallow the physical evidence whole. Trial continues in Plymouth Superior Court.
