Mistrial declared in Lindsay Clancy case after jury deadlock and denied emergency petition
Lindsay Clancy, a 36‑year‑old Massachusetts nurse, faced three first‑degree murder charges for the 2023 deaths of her children. Her defense maintained that postpartum psychosis should prevent criminal responsibility, while prosecutors argued she acted deliberately. After nearly 40 hours of deliberation, the 12‑person jury could not reach a unanimous verdict, and Judge William Sullivan declared a mistrial.
The Massachusetts Supreme Judicial Court denied an emergency petition filed by Clancy’s counsel, and the judge issued a formal mistrial. Clancy remains detained at Tewksbury State Hospital as prosecutors consider a possible retrial.
