According to the Associated Press, forensic psychologist Kirk Heilbrun testified in Plymouth County Superior Court on Monday that defendant Lindsay Clancy was not experiencing acute psychosis when she killed her three young children in January 2023. As the murder trial nears its conclusion, expert witnesses and legal teams remain sharply divided over whether severe postpartum mental illness or planned actions drove the tragedy.
Forensic Psychologist Challenges Defense Claims of Postpartum Psychosis
According to the Associated Press, Kirk Heilbrun testified that he questioned Clancy’s claims of hearing a hallucinated voice commanding her to kill her children. Heilbrun evaluated Clancy in April and told the court that hearing an unfamiliar voice once and never experiencing it again is an unusual manifestation of psychosis. Instead, Heilbrun testified that he believes Clancy took the lives of eight-month-old Callan, three-year-old Dawson, and five-year-old Cora so they would not suffer after she killed herself.
Clancy, 36, has pleaded not guilty to three counts of first-degree murder. Defense attorney Kevin Reddington argues that Clancy suffered from postpartum psychosis, bipolar disorder, and overmedication at the time of the killings in Duxbury, Massachusetts. Prosecutors contend that the former labor and delivery nurse planned the acts and deliberately sent her husband out to pick up medicine and dinner before strangling the children with exercise bands.
Police Testimony Sparks Courtroom Clash Over Alleged Coaching
Massachusetts State Police Sgt. Dan Lawlor faced intense questioning on day 12 of the trial regarding a state theory that a defense-hired psychologist coached Clancy on what to say. During a hospital visit shortly after the killings, forensic psychologist Dr. Paul Zeizel allowed Clancy to use his phone to call her husband Patrick. During that call, Clancy stated she had heard voices on the day of the killings.
Reddington challenged Sgt. Lawlor during cross-examination, asking if prosecutors were claiming that his expert told Clancy to mention hearing voices to build an insanity defense. The question prompted Assistant District Attorney Shanan Buckingham to object loudly, triggering a heated ten-minute sidebar with Judge William Sullivan while observers and jurors watched intently.
Divided Expert Testimony on Mental State and Culpability
According to the Associated Press, expert witnesses have offered starkly contrasting views on Clancy’s mental state throughout the proceedings. Dr. Phillip Resnick, a forensic psychiatrist and expert in filicide, testified on Friday that Clancy was clearly psychotic and acting like a puppet whose strings were pulled by someone else. Psychologist Paul Zeizel similarly concluded that Clancy had no appreciation for the wrongfulness of her acts.
Conversely, prosecution witnesses offered different conclusions. Dr. Avram Mack testified on Friday that he found no evidence of mania or psychosis leading up to the killings, characterizing Clancy’s state as a continuation of severe depression. Meanwhile, Heilbrun testified that he diagnosed Clancy with bipolar 2 disorder but maintained that she still understood her conduct was wrong, noting that she whispered “Go to God, baby” while strangling her children.
