Jurors in the Lindsay Clancy triple-murder trial reported Tuesday that they were not able to reach a unanimous decision.

Plymouth Superior Court Judge William Sullivan said he recognized the difficulty of agreeing on hundreds of hours of testimony and hundreds of exhibits of evidence, but instructed the jurors to resume deliberations.

After five weeks of testimony, the jury began its deliberations on the case Thursday. As of Tuesday morning, the nine women and three men had deliberated for about 18 hours.

The Duxbury woman has admitted to killing her three young children in 2023, but her defense claimed she was experiencing postpartum psychosis and should not be held criminally responsible for the crimes. Prosecutors argued she deliberately planned to kill the children, and that she did not believe she would face consequences as she intended to die by suicide.

Clancy, 36, is paralyzed from the waist down following an attempt to die by suicide immediately after strangling 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan.

The trial has garnered international attention and drawn hundreds of demonstrators to the Plymouth courthouse. Many supporters of Lindsay Clancy say they hope the case brings attention to mental healthcare, especially for new mothers.

If jurors remain at an impasse, they can report again to the judge. Sullivan could then issue an instruction known as “Tuey-Rodriguez” that advises jurors they are likely in the best position to decide the outcome of a case and should continue deliberations.
