Lindsay Clancy Trial: Postpartum Psychosis at the Center of the Murder Case
8/4/2026, 8:35:31 AM
Core Event – Fatal Strangulations and the Ongoing Trial
On January 24, 2023, Lindsay Clancy fatally strangled her three children—Cora, 5; Dawson, 3; and 8-month-old Callan—in the basement of their Duxbury, Massachusetts home using exercise resistance bands. She then attempted suicide by cutting her wrists and neck and jumping from a second-story window, leaving her partially paralyzed. The murders have led to a three-count murder trial in Massachusetts, now in its second week.
Medical Testimony on Psychosis and Patient Honesty
Psychiatrist Dr. Sejal Shah, associate chief of psychiatry at Brigham and Women’s Hospital, examined Clancy multiple times after the killings. In a January 30, 2023 assessment, Shah noted that Clancy denied suicidal or homicidal intent, reported no hallucinations, and displayed “organized” and “goal-directed” thought processes.
Forensic psychiatrist Dr. Jhilam Biswas met with Clancy on January 26, 2023 while she was on a ventilator. Using pen and paper, Clancy answered questions about her physical condition and requested an attorney.
Legal Arguments on Criminal Responsibility
Defense attorney Kevin Reddington focused on the medical experts’ acknowledgment that psychosis does not preclude coherent communication. He asked Shah whether Clancy was an “honest patient” and whether she had exaggerated symptoms for legal advantage.
Prosecutors, represented by Seth J. Zuckerson, emphasized that the burden lies with the state to prove Clancy’s criminal responsibility at the time of the deaths, a standard unique to Massachusetts.

The trial’s outcome will hinge on how the jury interprets the intersection of psychiatric science and Massachusetts law.
