Jury hears Massachusetts State Police investigator testimony in Lindsay Clancy murder trial

The jury in Plymouth Superior Court began the twelfth day of the Lindsay Clancy case by hearing from Sgt. Dan Lawlor, a nine-year veteran of the Massachusetts State Police who led the investigation into the 2023 deaths of Clancy’s three children—Cora, Dawson and Callan—in their Duxbury home. Prosecutors Jennifer Sprague and Shanan Buckingham maintain that Clancy fabricated a suicide attempt, whereas defense attorney Kevin Reddington contends that postpartum psychosis and overmedication should shield her from criminal responsibility.

Lawlor recounted his night-time movements, including visits to South Shore Hospital in Weymouth, Boston Children’s Hospital, and Brigham and Women’s Hospital, where he monitored Clancy after she jumped from a second-floor window. The defense probed the alleged link between psychologist Paul Zeizel’s court-ordered interview and a phone call Clancy supposedly made to her husband, Patrick Clancy, suggesting investigators were speculating without solid basis.

After a brief sidebar, the judge removed the jury while the prosecution continued questioning Lawlor without them, then reconvened the jury later. The trial proceeds with the possibility of a life-without-parole sentence if Clancy is convicted of first-degree murder, or commitment to a state psychiatric hospital if found not criminally responsible.
