Jury deadlocked after 36 hours in Lindsay Clancy murder trial

A Massachusetts judge declared a mistrial Friday in the Lindsay Clancy murder trial, Toronto Sun Crime reports, after the jury failed to reach a unanimous verdict following more than 36 hours of deliberations over seven days.

Clancy faced three counts of first-degree murder in the deaths of her children — five-year-old Cora, three-year-old Dawson, and eight-month-old Callan. The jury of nine women and three men told Judge Sullivan on two separate occasions that they were deadlocked; on both occasions, the judge sent them back to continue deliberating.

"It is with a heavy heart that we report we are unable to come to a unanimous decision," read the jury's note to the court.

A brief legal battle over the declaration itself

Because a mistrial only becomes official once read before the jury, defence attorney Kevin Reddington immediately sought an emergency stay from the Massachusetts Supreme Judicial Court. The stay briefly halted proceedings while the defence asked a higher court to intervene.

Judge Sullivan gave Reddington one hour to act. A hearing was scheduled before Justice Dalila Argaez Wendlandt at 1:30 p.m. — less than an hour later, Wendlandt issued her decision not to intervene. At 2:22 p.m. ET, Judge Sullivan called the jury back and formally declared a mistrial.

Postpartum psychosis at the centre of the defence

Clancy's defence team did not contest that she killed her children. Their argument was that she was not criminally responsible because she suffered from postpartum psychosis (PPP) at the time of the killings. Under Massachusetts law, a defendant is not guilty if they lacked criminal responsibility when committing an offence.

The Cleveland Clinic describes PPP as "a reversible — but severe — mental health condition that affects people after they give birth," adding that "people with postpartum psychosis have a much higher risk of harming themselves, dying by suicide or harming their children."

The prosecution countered that the killings were planned and intentional. More than 80 witnesses testified during the trial, with many addressing Clancy's mental state and the treatment she had received.

The case drew significant attention across the United States and internationally, bringing postpartum psychosis into broad public discussion.
