Plymouth Superior Court Judge William Sullivan directed jurors to return to deliberations Thursday morning after they failed to reach a verdict in the Lindsay Clancy murder trial following five days of discussions.

The panel of nine women and three men began deliberating on August 27 after hearing closing arguments and receiving instructions on charges that include first-degree murder, second-degree murder, manslaughter, and not guilty by reason of lack of criminal responsibility. They have now spent multiple days reviewing evidence from a trial that featured testimony from more than 80 witnesses and over 300 exhibits.

Lindsay Clancy faces charges in the January 2023 deaths of her three young children at the family home in Duxbury, Massachusetts. She admitted to the acts during the proceedings. The defense has maintained that she suffered from severe postpartum psychosis at the time and lacked the capacity to understand the wrongfulness of her actions or conform her conduct to the law. Prosecutors have argued that Clancy was criminally responsible for the killings.

The jury has twice indicated it could not reach a unanimous decision, prompting Sullivan to issue instructions urging continued efforts to agree, including a Tuey-Rodriguez charge. On the most recent occasion, the panel reported an impasse after more than 28 hours of deliberations before being sent home for the day.

Massachusetts law imposes no time limit for reaching a verdict. If the jury remains deadlocked after the judge's final efforts, a mistrial could result, allowing prosecutors the option to retry the case.

Clancy has been held at a state facility during the proceedings. The case has drawn significant attention due to the tragic circumstances and questions surrounding maternal mental health defenses in criminal trials.
