Lindsay Clancy Trial Set for July: Postpartum Psychosis Defense in Mother’s Killing of Three Children

Duxbury, Mᴀssachusetts — The long-awaited murder trial of Lindsay Clancy, the 34-year-old former labor and delivery nurse accused of killing her three young children in January 2023, is now scheduled to begin in July 2026, with her defense team preparing to argue that severe postpartum psychosis drove her actions in a tragic case that has captivated the nation.

Clancy is charged with three counts of first-degree murder in the deaths of her son Callan, 5, and daughters Cora, 3, and Dawson, 8 months. Prosecutors allege she strangled the children inside the family’s Duxbury home on January 24, 2023, before attempting suicide by jumping from a second-floor window. She survived with serious injuries. Authorities say she had researched methods of killing children and had searched for “how to kill my kids” and similar terms on her phone in the days before the incident.

The defense has signaled it will center on postpartum psychosis, a rare but severe mental illness that can cause hallucinations, delusions, and loss of touch with reality. Experts for the defense are expected to testify that Clancy was in the grips of the condition, which often emerges in the weeks or months after childbirth, and was not in control of her actions. She had been prescribed antidepressants and was under the care of multiple mental health providers at the time.

Prosecutors counter that Clancy was aware of her actions and had the presence of mind to plan the killings, pointing to her internet searches and the methodical way she carried out the crimes. They argue the psychosis defense does not negate premeditation or intent.

The trial, originally set for earlier dates, has been delayed multiple times as both sides prepare voluminous medical records, expert testimony, and psychological evaluations. Jury selection is expected to be lengthy given the high-profile nature of the case and the emotional weight of the allegations.

Clancy’s husband, Patrick Clancy, has publicly expressed support for his wife while grieving the loss of their children, describing the events as a “horrific tragedy” stemming from mental illness. The case has sparked widespread discussion about maternal mental health, the need for better postpartum screening, and the legal standards for insanity defenses.

As the July trial date approaches, the courtroom will become the center of a painful national conversation about postpartum psychosis, parental mental health, and the limits of criminal responsibility when severe mental illness collides with unimaginable loss.
