Mistrial in Lindsay Clancy Case as Supreme Judicial Court Denies Emergency Appeal

A judge declared a mistrial Friday in the murder trial of Lindsay Clancy, the Massachusetts woman accused of strangling her three young children in 2023, NPR National reports. The Massachusetts Supreme Judicial Court denied an emergency appeal from Clancy's defense attorney, clearing the way for Plymouth County Superior Court Judge William Sullivan to end the proceeding.

The jury had deliberated for six days before informing the judge it could not reach a unanimous verdict. Eleven jurors favored one outcome; one holdout refused to join them. The jury's note, as reported by WBUR, read: "It is with a heavy heart that we report we are unable to come to a unanimous decision, and we will not be able to."

Clancy, 36, was charged with strangling 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan inside the family's home in Duxbury, Massachusetts. The killings took place in January 2023.

Defense argued postpartum psychosis; prosecution disputed it

Her defense maintained that Clancy should not be held criminally liable because she was suffering from severe postpartum psychosis at the time of the killings — an approach commonly referred to as an insanity defense. The prosecution countered that Clancy was sufficiently aware of her actions to plan and act with intent.

The trial stretched over five weeks, included more than 80 witnesses, and drew international attention to the issue of postpartum mental health. Both sides agreed Clancy was struggling psychologically; the central legal question under Massachusetts law was whether her mental state left her unable to distinguish right from wrong or to conform her conduct to the law.

The defense called forensic psychologist Paul Zeizel, who testified that Clancy was experiencing postpartum psychosis at the time of the killings. Zeizel stated she reported hearing a male voice ordering her to kill her children and herself. She attempted suicide shortly after the children died. Her attorneys also argued she sought medical help repeatedly but did not receive effective care and was overmedicated. Clancy and her former husband, Patrick Clancy, have separately filed medical malpractice suits against some of her healthcare providers.

Emergency appeal rejected, mistrial follows

Before declaring the mistrial, defense attorney Kevin Reddington had asked the Supreme Judicial Court on Friday afternoon to either dismiss the holdout juror or require further inquiry into whether that juror could properly apply the law. Reddington wrote in the appeal that the holdout juror's "reasoning reflects a bias against those who suffer from debilitating mental illness."

On Thursday, Reddington had already asked Judge Sullivan directly to dismiss the holdout juror, citing two notes from the jury foreperson about the individual, who — according to Reddington — acknowledged doubt but refused to join the other 11 jurors in finding Clancy not guilty. Sullivan denied that request but provided the jury with new instructions on the meaning of reasonable doubt.

Reddington also asked Sullivan on Friday to poll the jury on whether they could agree on a lesser charge, such as second-degree murder or manslaughter, before a mistrial was declared — a move that would have prevented Clancy from being retried on first-degree murder. The judge denied that request as well.

After the Supreme Judicial Court declined to intervene, Sullivan declared the mistrial. He thanked jurors for their service in a difficult case. "Each one of you knew how long the case was going to go," Sullivan said. "You knew how difficult the case was going to be to listen to, facts wise. But still, you braced for that duty."

District attorney silent on retrial

Plymouth County District Attorney Tim Cruz held a press conference following the mistrial declaration but declined to say whether his office would pursue a retrial. He described it as an "emotional trial for everybody."

"But in the end, I bring it all back to the child victims in this case, Cora, Dawson, and Callen," Cruz said. "This was, and has always been, about getting justice for those three little babies."

Reddington, speaking outside the courthouse, argued the 11-1 split should give the prosecution pause. "If I was Tim Cruz, I would probably say I don't think I want to do a retrial because he's going to lose," Reddington told reporters.

He also praised Clancy for enduring the proceedings. "It's not right what she had to go through because she grieves the loss of those three children," he said. "Every time somebody had something to say about those young kids, Lindsey would smile and say, 'I'm glad.' She wants them to be remembered."

Clancy will remain in custody at a state hospital, where she has been held for more than three years. The district attorney has not set a timeline for a decision on retrial.
