Judge William Sullivan is set to consider several defense motions that could shape what happens next in the case. Sullivan declared the mistrial after jurors couldn't reach a unanimous verdict on first-degree murder charges tied to the deaths of Clancy's three children in their Duxbury home in 2023.
Clancy's attorneys don't dispute that she strangled her children. Instead, they argue she shouldn't face criminal responsibility because of postpartum mental health issues she was experiencing at the time.
The hearing matters for how the case moves forward. A hung jury means prosecutors have to decide whether to retry Clancy on the same charges, and any motions granted Tuesday could reshape what a second trial looks like, if there is one. For a case that already tested how courts weigh mental illness against criminal intent, the outcome could determine whether the case returns to trial.
A jury couldn't agree once on what happened inside that Duxbury home. Now a judge alone decides what happens next.
