The trial is not centered on whether the children were killed, but on Lindsay Clancy’s criminal responsibility and mental state. Jurors heard Patrick Clancy’s account, surveillance evidence and a 911 call from the day of the deaths.
Lindsay Clancy’s ex-husband testifies about the day she killed their three children: Patrick Clancy told a jury in Plymouth, Mass., on Wednesday that he returned to their Duxbury, Massachusetts, home in January 2023 and found the aftermath. The jury heard testimony and a 911 call in the murder trial involving the deaths of 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan.
The testimony matters because the central dispute is not whether Lindsay Clancy killed the children. Her lawyers argue she lacked criminal responsibility because of postpregnancy psychosis, while prosecutors say her actions that day showed planning and intent.
A father’s account in court
Patrick Clancy described the ordinary details that preceded the catastrophe: food, a pharmacy stop, a phone call about medicine and a quiet house when he came home. Those details are now part of the prosecution’s effort to show what happened inside the family’s home and how much Lindsay Clancy understood about her actions.
According to The Associated Press account published by PBS, Patrick Clancy testified that his last image of Dawson before leaving the house was the 3-year-old on the couch eating chicken nuggets and green beans. Lindsay Clancy had asked him to pick up food and stop at a pharmacy.
Jurors also watched surveillance video from the pharmacy showing Patrick Clancy calling his wife with a question about which medication to buy. He testified that she sounded quiet and busy, and that he assumed she might have been giving the children baths.
When he returned, he said, the home was silent. He searched and found blood in the main bedroom. Lindsay Clancy, badly injured but conscious after attempting to take her own life, told him the children were in the basement, he testified.
The 911 call became evidence
The jury listened to Patrick Clancy’s 911 call as part of Wednesday’s testimony. The AP reported that he can be heard sobbing and screaming after finding the children, who had been strangled with exercise bands.
In the call, a confused dispatcher repeatedly asks what happened before Patrick Clancy says, “She killed the kids,” according to the AP account. In court, Lindsay Clancy sobbed as the recording was played, while her parents also appeared to cry. Patrick Clancy had left the courtroom after his testimony ended.
The call is powerful evidence because it captures the immediate aftermath, before the legal arguments hardened into trial positions. For jurors, it is both an emotional record and a factual one: a timeline of discovery, panic and emergency response.
For the court, the challenge is to keep that emotional force separate from the legal questions jurors must answer. Grief explains the human stakes. It does not, by itself, decide criminal responsibility.
The trial turns on intent
Prosecutors say Lindsay Clancy acted intentionally and should be held fully responsible for the deaths of Cora, Dawson and Callan. They point to the errand request and pharmacy stop as evidence that she created a window of time when Patrick Clancy would be away from the house.
The defense presents a sharply different explanation. Her lawyer says she was suffering from postpregnancy psychosis, a severe mental illness that can distort a person’s sense of reality after childbirth. The defense has said she heard voices telling her this was her “last chance” and directing her to kill the children and then herself, according to the AP report.
That distinction is the core of the case. The defense does not need to convince jurors the children were not killed by their mother. It must persuade them that, because of her mental state, she lacked criminal responsibility under the law.
If convicted of murder, Lindsay Clancy faces life in prison without parole. If found not guilty because of a lack of criminal responsibility, she would be committed to a state mental health facility, according to the AP.
Her mental health history looms
Patrick Clancy also testified earlier in the week about his former wife’s deteriorating mental health before the killings. He described intrusive thoughts involving harm to the children and suicide, but also said she had appeared to be doing better as recently as two weeks before the deaths.
On the day of the killings, he testified, the day began as one of her “best days.” She took Cora to a doctor’s appointment, returned home, built a snowman with the children and worked on art projects with them.
That evidence can cut in different directions. Prosecutors may argue that outward calm and ordinary activities support the idea that Lindsay Clancy knew what she was doing. The defense may argue that severe mental illness can fluctuate, appear hidden and become catastrophic even after moments that look normal to family members.
The AP reported that Lindsay Clancy had sought treatment from specialists in postpregnancy mood disorders, had been prescribed multiple psychiatric medications and checked into a psychiatric hospital when treatment was not working. The children were killed 19 days after her discharge.
Postpartum psychosis, not depression
Postpartum psychosis is rare and distinct from postpartum depression. The Cleveland Clinic describes it as a mental health emergency that affects a person’s sense of reality. The AP cited estimates that it occurs in about 1 to 2 women per 1,000 after delivery.
Postpartum depression is far more common and can be serious, but it does not necessarily involve psychosis. Postpartum psychosis can include delusions, hallucinations, severe confusion, paranoia, agitation or sudden shifts in behavior. It requires urgent medical attention.
Researchers have found that risk can be higher for people with certain mental health histories. The AP cited a 2023 journal article from researchers at the Medical University of Lublin in Poland saying about half of people with postpartum psychosis have a prior psychiatric history, with bipolar affective disorder identified as a common risk factor.
In court, though, medical context is only one part of the analysis. Jurors must weigh expert testimony, family observations, records of treatment, the events of the day and the legal standard for criminal responsibility.
What jurors must still decide
The trial now asks jurors to hold two difficult truths at once: three children are dead, and their mother’s mental state is the decisive legal question. That is why Patrick Clancy’s testimony is so central. His account gave jurors the final ordinary moments before the deaths, the discovery afterward and a window into what he observed about Lindsay Clancy’s condition.
What remains unclear is how jurors will interpret the same facts. A planned errand can look like evidence of intent. A history of treatment, intrusive thoughts and alleged voices can look like evidence of psychosis. The law requires jurors to decide which interpretation meets the burden in court.
The case also carries a broader public tension. Advocates for maternal mental health warn that rare emergencies like postpartum psychosis are often misunderstood until tragedy occurs. Prosecutors, representing the state and the children, are asking jurors to focus on accountability for three deliberate killings.
