Eleven of 12 jurors were ready to clear Clancy of criminal responsibility last Friday, but their deadlock forced the judge to declare a mistrial, leaving the case unresolved.
Attorney Kevin Reddington's motion asked the same judge to acquit Clancy, which would prevent a second trial. Prosecutors have yet to say whether they'll seek to put the 36-year-old former labor and delivery nurse on trial again, and Plymouth County District Attorney Timothy Cruz did not respond to a phone message Thursday seeking comment.
Neither side disputed that Clancy strangled 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan Clancy in the family's home in 2023 before trying to end her own life. But her attorney claimed she was a loving mother in the grip of a rare condition called postpartum psychosis, while prosecutors argued she knew what she was doing.
The trial generated intense interest for weeks, drawing attention to maternal mental health after childbirth. But many observers say the state of Clancy's mental health is not enough to absolve her of the responsibility for planning and then murdering her three children.
