Defense attorney Kevin Reddington demanded that a juror be removed from deliberations in the Lindsay Clancy murder trial on Thursday as the panel remained deadlocked.

Reddington issued the warning during proceedings at Plymouth Superior Court, where jurors have spent multiple days trying to reach a unanimous verdict on whether Clancy bears criminal responsibility for the deaths of her three young children.

"If we come back here in half an hour with a mistrial because of a juror who has just spurned the instructions of this court, it’s a shame," Reddington said.

The jury has already signaled deadlock on prior days, prompting Judge William Sullivan to issue instructions urging continued deliberations. The panel returned for what could be a decisive day of talks on Thursday.

Clancy, 36, faces charges in the January 2023 deaths of her children, ages 5, 3, and 8 months, at the family home in Duxbury, Massachusetts. Prosecutors allege she strangled the children with exercise bands. The defense maintains she was not criminally responsible due to severe mental illness, including postpartum psychosis.

A mistrial would leave the case unresolved and expose Clancy to a potential retrial. The prolonged impasse has drawn attention to the challenges of high-profile cases involving mental health defenses and the expectations placed on jurors to follow judicial guidance.

Deliberations resumed Thursday morning after the latest deadlock note. The court has emphasized the need for jurors to examine evidence thoroughly and respect differing views while striving for unanimity.
