Lindsay Clancy Trial: 180 Hours of Records Later, a Different Diagnosis Emerges

The prosecution's own rebuttal witness may have handed the defense some of its strongest material yet in the Lindsay Clancy murder trial. Forensic psychologist Dr. Kirk Heilbrun testified Monday about the months before Clancy allegedly strangled 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 in Duxbury, Massachusetts. Clancy, 34, faces three counts of murder and three counts of strangulation, has pleaded not guilty, and her attorney Kevin Reddington is arguing severe postpartum psychosis and psychiatric overmedication.Heilbrun began with a lesson in retention bias — the pull toward favoring whoever's paying for the evaluation — then detailed the scope of his own work: about 180 hours combing through police, medical, and court records plus surveillance footage, 10.5 hours testing and meeting with Clancy directly, and 1.5 hours of collateral interviews. His timeline was specific. Limited medical history and mild anxiety before September 2022. Worsening anxiety and depression after October 2022. By December 2022, intrusive and unwelcome thoughts about self-harm and, at times, harming the children — thoughts, he clarified, not hallucinations.Then came the diagnostic contradiction: Heilbrun found no evidence in the records of mania or hypomania consistent with bipolar disorder, even though Tewksbury Hospital had Clancy diagnosed with bipolar disorder for three and a half years. His own conclusion was bipolar II. He closed by outlining the legal insanity standard — mental disease or defect, capacity to know right from wrong, and ability to control conduct. After the killings, Clancy allegedly attempted suicide by jumping from a second-story window and is now paralyzed from the waist down. The trial continues in Plymouth Superior Court.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?
