A Massachusetts jury has begun deliberating in the trial of Lindsay Clancy, who admitted strangling her three children in January 2023 but denies murder on grounds of insanity. The case centres on whether prosecutors proved she intended to kill the children and whether her mental state, including alleged postpartum psychosis and prescribed medication, removed her criminal responsibility.

Jurors may find Clancy guilty of first-degree murder, second-degree murder or manslaughter, with murder carrying life imprisonment and manslaughter carrying a maximum 20-year sentence. If they find her not criminally responsible, she would be committed to a state mental health facility; a failure to reach unanimity would result in a mistrial. The 12-person jury, comprising nine women and three men, was sent out after closing arguments from both sides.
