Lindsay Clancy mistrial declared after jury deadlocks in killings of her three children

Judge William Sullivan declared a mistrial Friday in murder case after jurors said they were unable to reach a unanimous verdict in the killings of her three children after a week of deliberating at the Plymouth Superior Court in Plymouth, Massachusetts.

The mistrial followed a dramatic dispute over an alleged 11-1 divide, with Clancys defense arguing that the lone holdout juror had acknowledged doubt but was refusing to properly apply the courts instructions on reasonable doubt.

The alleged holdout is believed to be one of the three male jurors on the 12-person panel after defense attorney Kevin Reddington repeatedly referred to the unnamed juror as a male inside and outside the court.

"[The other jurors] know that they were robbed — by one man — for whatever his agenda was, who stole seven weeks of the life of these other jurors that were so attentive, so beautiful, so wonderful, and listened to this evidence," he told reporters after leaving the courthouse. "And you could see how defeated they were sitting there. And I got a funny feeling they could go one for another week if they had to. So I hope that guy can sleep well at night."

Also speaking outside the courthouse, Plymouth County District Attorney Tim Cruz acknowledged the victims in this case — the Clancy children, 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan. 

"It is our job to make sure the victims are not invisible," he said. "I am a father and a grandfather, and I cannot imagine the hell this entire family has lived through."

Clancys attorneys made an emergency appeal to the Massachusetts Supreme Judicial Court in an attempt to stay the mistrial and force further inquiry into the juror. Justice Dalila Argaez Wendlandt denied the request Friday afternoon, clearing the way for Sullivan to formally declare the mistrial.

Clancy had been charged with first-degree murder in the January 2023 deaths of her children, each of whom had been strangled with exercise bands.

The trial centered on whether she was legally responsible for her actions at the time, and the defense argued she wasn't due to postpartum psychosis.

Her attorneys argued that severe mental illness left her unable to appreciate the wrongfulness of what she was doing or unable to conform her conduct to the requirements of the law.

Prosecutors maintained that Clancy remained criminally responsible and pointed to evidence they said showed planning, purposeful behavior and an awareness of what she was doing before, during and after the killings.

During the trial, Clancy's former husband, Patrick Clancy, testified about the day of the slayings, which happened while he was running errands that included picking up children's stool softener at a CVS store and takeout for dinner. They spoke on the phone while he was out.

Under Massachusetts law, once lack of criminal responsibility is properly raised, prosecutors must prove beyond a reasonable doubt that a defe
