US mother's mental health spiralled before her children's murders, ex-husband says

July 27, 2026

Lindsay Clancy is on trial in Massachusetts for the January 2023 murders of her three young children, facing life imprisonment if convicted of first-degree murder. Her ex-husband Patrick testified that her mental health deteriorated significantly in the month preceding the deaths, describing her severe depression, weight loss, and suicidal thoughts despite seeking medical help and switching psychiatrists. Prosecutors argue that Clancy acted deliberately and rationally in killing her children, while her defense team contends she was experiencing postpartum psychosis and was not criminally responsible for her actions.

Who is affected

Lindsay Clancy (the defendant facing three counts of first-degree murder)
Cora (age 5), Dawson (age 3), and Callan (8 months old) - the deceased children
Patrick Clancy (ex-husband and father of the children, testifying as a witness)
The 12-member jury deliberating the case
Law enforcement, firefighters, family, friends, and psychiatrists who will testify as witnesses

What action is being taken

The trial is currently proceeding, with prosecutors calling witnesses including law enforcement, firefighters, family, friends, and psychiatrists
Patrick Clancy is testifying about his ex-wife's mental health and relationship with the children
Prosecutors are attempting to convince the jury that Clancy deliberately committed murder
The defense is presenting an insanity defense, arguing she was suffering from postpartum psychosis

Why it matters

This case raises critical questions about postpartum mental health care and the criminal justice system's treatment of severe psychiatric conditions. It highlights the devastating consequences when postpartum psychosis—a rare but serious psychiatric emergency affecting approximately 1 in 1,000 mothers—goes untreated or inadequately treated. The trial's outcome will determine whether severe postpartum mental illness can constitute a valid insanity defense, potentially setting precedent for how the legal system handles cases involving maternal mental health crises and establishing accountability standards when mothers experiencing psychosis harm their children.

What's next

The trial is expected to continue for several more weeks
Prosecutors will call additional witnesses including law enforcement, firefighters, family, friends, and psychiatrists
The jury will ultimately decide whether Clancy is guilty of first-degree murder or not criminally responsible due to insanity
