A single juror blocked a verdict in the Lindsay Clancy child-killing trial, forcing a mistrial.
After seven days and roughly 38 hours of deliberations, Plymouth Superior Court Judge William Sullivan declared a mistrial Friday. The 12-person jury, nine women and three men, could not reach the unanimous decision required under Massachusetts law. Notes from the panel revealed an 11-to-1 split. When Sullivan thanked the jurors and dismissed them, several reportedly bowed their heads.
The case centered on Clancy, a 36-year-old former labor and delivery nurse who admitted to strangling her three young children inside the family’s Duxbury, Massachusetts home on January 24, 2023. The victims were five-year-old Cora, three-year-old Dawson, and eight-month-old Callan.
The question before the jury was never whether Clancy killed her children. She admitted that. The dispute was whether she could be held legally responsible for those actions.
Her defense attorneys argued she was in the grip of postpartum psychosis and had lost touch with reality at the time of the killings. Prosecutors countered that she understood right from wrong and had deliberately arranged to be alone with the children by sending her husband out to pick up medication and food before the attacks. Critics were not buying that defense and demanded her be in jail for life – or worse.
As originally reported, the five-week trial featured testimony from more than 80 witnesses and hundreds of exhibits. Jurors were permitted to weigh several possible outcomes, including murder, manslaughter, or a finding of no criminal responsibility.
Tensions in the courtroom sharpened in the final days when the jury foreperson reportedly told Sullivan that one juror was refusing to follow his instructions on reasonable doubt. Defense attorney Kevin Reddington asked the judge to question or remove that juror. Sullivan declined, saying he would not probe the internal deliberations of the panel.
After jurors reported for a third time that they remained stuck, Sullivan announced his intent to declare a mistrial. Reddington requested a short delay and filed an emergency petition with the Massachusetts Supreme Judicial Court, asking the higher court to order Sullivan to remove the holdout before ending the trial. The state’s highest court denied that request. Sullivan then formally declared the mistrial and released the jury.
The ruling ends this trial but does not dismiss the charges against Clancy. No acquittal was entered. Prosecutors now face three options: pursue a second trial before a new jury, negotiate a plea deal with the defense, or decline to continue the case.
No decision on a potential retrial was announced Friday.
