Lindsay Clancy Murder Trial: Jury Deadlocked After Three Days of Deliberations
Jurors in the Lindsay Clancy trial said Tuesday they cannot reach a unanimous verdict on whether the Massachusetts mother bears criminal responsibility for killing her three children.

Clancy Jury Reports Deadlock, Judge Orders Them to Continue
Jurors in the Lindsay Clancy trial told a Plymouth, Massachusetts judge Tuesday that they have been unable to reach a unanimous decision after more than three full days of deliberations, Courthouse News Service reports. Judge William Sullivan instructed the panel to return to the deliberation room and keep trying.
"I know that this was a long trial, all right," Sullivan told the jury. "I know there were over 80 witnesses. There were over 300 exhibits. But because of that, I'm going to ask you to go back out."
Clancy, 36, a former labor and delivery nurse, does not dispute that she strangled her three young children — Cora, 5, Dawson, 3, and 8-month-old Callan — in the basement of their home south of Boston. She has pleaded not guilty by reason of lack of criminal responsibility, citing postpartum psychosis as the cause of her actions.
Tuesday marked the first sign of an impasse. Clancy stared straight ahead as the jury entered the courtroom, then turned to look at the panel as the judge addressed them.
Charges and Possible Outcomes
The jury may convict Clancy of murder or manslaughter, or acquit her if jurors conclude her deteriorating mental health rendered her not criminally responsible. A murder conviction could carry a life prison sentence. An acquittal would not necessarily mean freedom — a judge could still order her committed to a mental health facility if an evaluation finds she poses a danger to the public.
Deliberations began Thursday afternoon. The only notable request from the jury came Friday, when jurors asked to examine a knife Clancy used to cut herself and bags containing empty prescription pill bottles found in her home.
Competing Accounts of Mental State
The trial, which ran more than four weeks, centered on sharply conflicting medical expert testimony about Clancy's mental condition following the birth of her third child.
Her defense attorney argued that Clancy loved her children but killed them because postpartum psychosis — a rare and severe mental illness that can follow childbirth — caused her to lose touch with reality. In the months preceding the killings, Clancy sought treatment from multiple providers and checked herself into a psychiatric hospital. She was discharged less than three weeks before the killings.
On the day of the deaths, she sent her husband Patrick Clancy on an errand, then killed the children with exercise bands. She subsequently jumped from a second-floor window and remains paralyzed from the waist down.
A defense psychologist testified that Clancy did not recognize the "wrongfulness" of killing her children because of her mental health condition. Both her mother and sister testified that she had become anxious, paranoid, and suicidal in the period leading up to the incident.
Prosecutors offered a different account. They argued Clancy was depressed and tired of living, and made a conscious decision to kill her children before attempting suicide. A forensic psychologist testifying for the prosecution concluded that Clancy killed her children because she did not want to leave them behind when she ended her own life.
Husband's Testimony
Jurors spent two days listening to testimony from Patrick Clancy, including recordings of his anguished 911 call. He was still on the phone when he found the children's bodies, minutes after discovering his wife badly injured in the yard.
Patrick Clancy has said publicly that he forgives his ex-wife, whom he regards as ill rather than evil. The trial marked the first time he had seen Lindsay Clancy since the killings took place.
Clancy did not testify in her own defense. She observed the proceedings from the defense table, and was seen weeping at points — including when prosecutors displayed autopsy photographs of the children to the jury.
Postpartum Psychosis at the Center of the Case
The trial has drawn widespread public attention and stirred deep divisions, given its focus on maternal mental health after childbirth. Postpartum psychosis is more severe and far less common than postpartum depression. Researchers estimate it affects 1 to 2 out of every 1,000 women following delivery. While most women who develop the condition do not harm their children, severe cases can involve attempts to harm themselves or their children.
