WATCH: Judge Declares Mistrial in Lindsay Clancy Case After Hours-Long Delay

The sensational criminal case of a Massachusetts mother who admitted killing her three young children with an exercise band in what she said was a fit of postpartum psychosis ended in a mistrial Friday after days of deliberation and hours of legal drama.

After more than six days of deliberation, the jury of nine women and three men began Friday by again telling Judge William Sullivan they again could not reach a unanimous decision in the case against Lindsay Clancy, giving their “deepest regrets” at being unable to reach a verdict.

It was the third time in a week the jury had voiced its inability to decide, with Thursday’s proceedings revealing the group stood on the precipice of an acquittal, with 11 jurors deeming the 36-year-old Clancy not guilty, with one lone holdout.

As Sullivan began to declare a mistrial early Friday, Clancy’s lead defense attorney, Kevin Reddington, dramatically sought an emergency appeal — with the judge allowing one hour for Clancy’s defense to go to the Supreme Judicial Court of Massachusetts, the state’s top court.

The request led to a more than two-hour delay as Reddington’s associate, Dana Goldblatt, asked a Supreme Judicial Court judge via Zoom to remove the holdout juror, insisting he was failing to “follow what the law states,” according to NBC News.

The legal Hail Mary failed, with the court denying the request, and jurors were eventually brought back into the courtroom, where Sullivan addressed them directly.

“At this point I’m going to declare the jury is deadlocked and I’m going to declare a mistrial,” he said.

Sullivan praised the jurors for their diligence.

“I watched every day, day after day, week after week, all of you, performing that duty that you braced for and I just wanted to kind of let you know I understood how hard everybody worked,” he said. “I just want to thank you so much. You should be proud of what you did.”

Clancy and her husband, Patrick Clancy, shared children Cora, 5, Dawson, 3, and 8-month-old Callan and were married for six years before the fateful day in January 2023 when the mom brought her babies into the basement of their Duxbury, Mass., home, about 90 minutes south of Boston.

By all accounts and trial testimony, the day Lindsay killed her children began typically.

She took Cora to the doctor for a stomachache, built snowmen with the children, and texted with her husband, who worked in tech sales.

Patrick left the home around 5:15 p.m. that night to pick up a takeout order and medicine for Cora.

By the time he returned at 6 p.m., his children were dead and his wife had attempted suicide.

She later admitted to the killings in a civil proceeding, but consistently pleaded not guilty to criminal charges.

Lindsay Clancy, a former labor and delivery nurse, was arraigned in February 2023 with three counts of murder, and her defense team, led by Reddington, argued she could not be held criminally responsible due to reason of insanity, and insisted she was suffering from both postpartum psychosis and bipolar disorder.

She faced life in prison without parole if convicted of the top count of first degree murder.

The case captivated the nation, and prompted dissection and discussion about postpartum healthcare, maternal healthcare, mental health, and parenthood.

Despite hiring a nanny and having relatives who stayed with them to help with the children, the mom claimed her postpartum symptoms became difficult to bear as her maternity leave with Callan, whom she was trying to wean, was ending.

She began to seek help from multiple medical providers and was prescribed a litany of medications.

But the prosecution argued Clancy wasn’t always honest with her providers about what medication she was taking and for how long. She was diagnosed with generalized anxiety in September 2022 and prescribed talk therapy and Zoloft; a doctor also completed a form at the time that extended her maternity leave.

Lindsay opted to stop using Zoloft due to side effects and was prescribed Ativan the following month. She was prescribed a third medication, Buspar, in October 2022 but didn’t take it; she reported intrusive thoughts in December of the same year.

She had voluntarily checked herself into inpatient psychiatric care on Jan. 1, 2023.

Less than a month later, her children were dead.

Patrick Clancy, who later divorced Lindsay, has also filed a lawsuit against her medical providers.
