Lindsay Clancy murder trial ends in a hung jury after nearly 40 hours

Plymouth Superior Court Judge William F. Sullivan declared a mistrial on Friday in the murder case against Lindsay Clancy after jurors said they could not reach a unanimous verdict. The panel had deliberated for about 37 to 40 hours across seven days, following more than four weeks of testimony. A mistrial is not an acquittal. The first-degree murder charges remain. Clancy, 36, a former labour and delivery nurse, was returned to Tewksbury Hospital and is still held without bail.

The case concerns the deaths of her three children in Duxbury in January 2023. Prosecutors say she strangled Cora, 5, and Dawson, 3, with exercise bands and that Callan, 8 months, died days later. Clancy then fell from a window. Her lawyer, Kevin Reddington, argued she was not criminally responsible because she was in a state of postpartum psychosis, with other clinicians pointing to bipolar disorder. The legal question for the jury was not whether the children died. It was whether the state had proved she was criminally liable for those deaths.

Jurors told Sullivan three times that they were deadlocked. He sent them back. On Friday he said he would declare a mistrial. Reddington asked for time to seek an emergency stay from a single justice of the Massachusetts Supreme Judicial Court, arguing that a holdout juror should be removed and that a mistrial would waste a case that had consumed weeks. The higher court denied the request. Sullivan then discharged the jury, over the defence objection.

Plymouth County District Attorney Timothy J. Cruz told reporters no decision on a retrial would be made on Friday. Sullivan scheduled a status conference for 29 September and said he favoured trying the case sooner rather than later, without setting a date. Reddington said he wanted a second trial as early as the week after next. The lead prosecutor said she would be out of the state for two weeks. Under Massachusetts law, only a jury can decide first-degree murder. Cruz, not the judge, decides whether to spend the resources again.

A hung jury in a case built on psychiatric evidence is a known risk. Twelve people can agree on the facts of the afternoon and split on the meaning of psychosis. Some jurors treat postpartum psychosis as a medical event that breaks criminal intent. Some treat the same record as proof that a mother who could plan a strangling could form intent. Forty hours of deadlock is the sound of that split, not of confusion about names and dates.

Cruz runs an office that also operates an advocacy centre for child-abuse victims. That institutional fact will be read into his retrial decision even if he never mentions it. A second trial would put the children's last hours in front of a new panel and a new set of cameras. Declining to retry would leave the public record as a hung jury and a mother in a locked hospital. Both paths have a cost. Only one of them requires another six weeks of court time.

Clancy is not going home. The hospital hold and the open murder indictment are the present tense of the case. The 29 September hearing is where Cruz has to say, on a date certain, whether the state will ask twelve other people to do what this jury could not.
