In a quiet courtroom in Plymouth, Mᴀssachusetts, a note from the jury changed the temperature of a case the country has been watching for weeks. After four days of closed-door talks, the 12 jurors deciding Lindsay Clancy’s fate told the judge they could not reach a unanimous verdict. They did not get to go home with the case finished. Judge William Sullivan thanked them, acknowledged how large the trial had been, and sent them back to keep working. By late Tuesday they asked to stop for the night and return Wednesday morning. That is where the case stood as a fifth day of deliberations began.

The note was short and blunt: after many hours, they were unable to come to a unanimous decision. People in the gallery gasped when it was read. Clancy, seated in a wheelchair beside her lawyer, looked ahead at first and then toward the jurors as the judge spoke. She has been paralyzed from the waist down since January 2023, when she jumped from a second-floor window after the deaths of her three children. She is 36 now. She is a former labor and delivery nurse. She does not deny that she caused the deaths of Cora, 5; Dawson, 3; and Callan, 8 months, in the family’s Duxbury home on January 24, 2023. The fight in this trial has never been about whether those deaths happened. It has been about whether she can be held criminally responsible for them.

That single legal question is why the jury is struggling. Mᴀssachusetts requires a unanimous verdict. The panel of nine women and three men can find her guilty of first-degree murder, second-degree murder, or manslaughter, or they can find her not guilty because she lacked criminal responsibility, or not guilty outright. Lack of criminal responsibility, in this state, means the prosecution must prove she could understand the wrongfulness of her conduct and could control her behavior in line with the law. If even one juror holds out, there is no verdict. After roughly 23 hours of talks spread across Thursday through Tuesday, that is the wall they hit.

Sullivan did not call a mistrial. He reminded them that they had heard more than 80 witnesses and seen more than 300 exhibits in a trial that ran about six weeks. Because of that volume, he said, they should go back and continue. There is no clock in Mᴀssachusetts that forces a jury to stop after a set number of hours. A judge can keep a panel working as long as he still believes a verdict is possible. If they report another impᴀsse, the next step can be a special instruction known in Mᴀssachusetts as Tuey-Rodriguez, a last-resort charge urging jurors to re-examine their views without surrendering an honest belief. If that still fails, a hung jury and a mistrial become more likely. Charges would not disappear. Prosecutors would then decide whether to try the case again. Defense attorney Kevin Reddington has already said he would defend Clancy a second time if that happens.

The story the jurors have been asked to sort out began after the birth of Clancy’s third child in 2022. Relatives later described a woman who became anxious, fearful, sleepless, and, they said, unlike herself. She sought psychiatric care, took a changing mix of medications, entered an outpatient program, and spent several days in a psychiatric hospital. Less than three weeks after discharge, on the day of the killings, she asked her then-husband, Patrick Clancy, to leave on an errand. When he came home, he found her injured outside and the children ᴅᴇᴀᴅ in the basement. His 911 call was played for the jury. He testified for two days. In later interviews he has said he sees her as ill, not evil, and that he has forgiven her. The trial was the first time he had seen her since that night.

The defense theory is that she loved her children and lost contact with reality. Lawyers say bipolar illness and postpartum psychosis, worsened by a difficult course of treatment, left her unable to understand or control what she was doing. They say she heard a commanding voice telling her to kill the children so she could end her own life. She did not take the stand. Journals and medical records from the months before the deaths were read in court, including entries about brain fog, drowning in daily care, desperation for a mental break, and a wish to get well. The prosecution’s theory is different. Prosecutors say she was depressed and exhausted, but that she still knew what she was doing and made a deliberate choice. A forensic psychologist called by the state testified that he believed she wanted to die and did not want to leave the children behind. In closings, prosecutors described her as a functioning mother who still knew right from wrong.

Postpartum psychosis is rare. Researchers generally estimate it in about one or two of every 1,000 births. It is more severe than ordinary postpartum depression and can include delusions, hallucinations, and a break from reality. Experts say it is often linked to bipolar disorder and is treated as a psychiatric emergency. The Clancy trial has pushed that diagnosis into public view in a way few cases have. Some psychiatrists argue the publicity will force better screening and faster care. Others worry the courtroom fight has flattened a complicated illness into a simple question of whether “the system failed her,” and that fear of liability could make clinicians more cautious about treating new mothers. Those debates are outside the jury room. Inside it, the only question that matters is whether this defendant, on that day, met the legal test for criminal responsibility.

If the jury convicts her of first-degree murder, she faces life in prison. A finding that she lacked criminal responsibility would not automatically send her home. A judge can still order her held in a psychiatric facility if she is found to be a danger. A mistrial would freeze the case in place and reopen every painful choice for both sides. That is why Tuesday’s ᴅᴇᴀᴅlock felt like a turning point without being an ending. The jurors went home. The judge thanked them. He told them not to read or talk about the case. Wednesday was scheduled to begin the same way the last four days began: twelve people, a locked room, and a question they have not yet been able to answer together.
