The facts at the center of the Lindsay Clancy case are not disputed in any meaningful sense. On January 24, 2023, in Duxbury, Massachusetts, Clancy sent her husband, Patrick, out to pick up dinner and medication from CVS. While he was gone, she fatally strangled their three children — Cora, Dawson and Callan — with exercise bands in the basement, then cut her own wrists and neck and jumped from a second-floor window, according to trial testimony. Patrick came home, found the scene, and called 911. What remains disputed, after six weeks of trial and four days of deliberations, is the only question the law cares about: whether she was criminally responsible for it.
CNN assembled a timeline of the case, and what it shows most clearly is how fast the collapse came. Clancy, a labor and delivery nurse, gave birth to her third child in May 2022. By September 2022 she was meeting over telehealth with a psychiatrist, Dr. Jennifer Tufts, for anxiety, depression and insomnia; over the following four months she was prescribed roughly a dozen medications and saw multiple providers as her condition worsened. On December 31, 2022, she was admitted to McLean Hospital after reporting suicidal thoughts and intrusive thoughts of hurting the children, and was released after five days to attend her daughter’s birthday party. On January 23, 2023 — the day before the killings — she told Tufts she was “doing all right,” denied any suicidal or homicidal ideation and showed no signs of psychosis, according to Tufts.
Afterward, hospitalized and partially paralyzed, Clancy wrote on paper that she was “horrified” and asked for a lawyer. She told her husband and a hospital chaplain that she had heard a persistent male voice directing her to kill the children and herself — an account she repeated in a lawsuit she filed against her medical providers in January 2026: “I lost all control. My body started acting without any control on my part.”
She was arraigned from her hospital bed February 7 and indicted September 15, 2023, on three counts of murder. The trial began with jury selection on July 20, 2026, in Plymouth. The prosecution’s theory, laid out in openings on July 26, was that she “acted intentionally, rationally and swiftly.” The defense’s was that she was in the grip of postpartum psychosis and therefore not criminally responsible — the insanity defense, which asks a jury to set aside what someone did and judge instead what their mind was doing at the time.
The evidence split the same way. The prosecution called more than 70 witnesses over three and a half weeks — family, friends, first responders, investigators and medical providers — before resting August 17. The defense called 10, including psychiatric experts who said Clancy suffered from postpartum psychosis, and rested August 21. The prosecution’s rebuttal, three mental health experts who testified she was not psychotic at the time, closed August 26. On August 20, more than 100 people in pink gathered outside Plymouth Superior Court in support of Clancy and to raise awareness of maternal mental healthcare.
Then the case went to twelve people, and it stalled. Deliberations began August 27. On September 1, the jury reported it was “unable to come to a unanimous decision” and was told to keep going. On September 3, a note indicated an 11-to-1 split, with the holdout juror said by defense attorney Kevin Reddington to “refuse to listen to the law” on reasonable doubt; after a heated exchange with Reddington, Judge William Sullivan questioned each juror individually, and each said they could follow his instructions. On September 4, with the deadlock unchanged and a defense emergency appeal to further question the holdout denied, Sullivan declared a mistrial. Separately, a 56-year-old woman was arrested outside court for allegedly filming jurors and later pleaded not guilty.
What happened inside that room afterward is unusually well documented. Three jurors told NBC10 Boston on September 8 that a single male juror “admitted he had reasonable doubt” but still declined to vote not guilty by reason of insanity — a position that is, on its face, legally incoherent, since reasonable doubt is supposed to produce acquittal. On September 17 the holdout issued his own statement flatly contradicting that account: he believed the evidence pointed to guilt. “I didn’t have any doubts,” he said.
So the outcome everyone is left with is this: eleven jurors one way, one juror the other, no verdict, and two irreconcilable public stories about what the holdout actually thought. Reddington declared that the defense won the case and criticized the holdout; on September 9 he told CNN’s Anderson Cooper he was open to a plea deal.
Patrick Clancy, who divorced Lindsay and testified as the trial’s first witness, has been the case’s most complicated figure for years. He told The New Yorker in October 2024: “I wasn’t married to a monster – I was married to someone who got sick.” On September 20 he and his new wife, Dr. Rachel Danis, spoke to 60 Minutes about the children, the trial and his own self-blame: “I think I did the best I could with what I had at the time, and I live with the outcome.”
The legal machinery, meanwhile, is still running. At a September 29 hearing, Reddington argued the prosecution had failed to present sufficient evidence that Clancy killed the children at all — “Where is the evidence that she did this?” — which prosecutors called “laughable.” On October 1, Judge Sullivan denied that motion, finding the trial evidence sufficient for a reasonable juror to convict. He is still weighing other defense motions, with a follow-up hearing set for November 2. Plymouth County District Attorney Timothy Cruz has said the prosecution will decide “shortly” whether to retry the case. The core question — how a legal system is supposed to adjudicate an act that everyone agrees happened and almost no one believes was chosen — gets another few months to sit unresolved.
