The defense blamed one juror for the deadlock.

The murder trial of Lindsay Clancy, the Massachusetts mom who killed her three young children while in the family's home on Jan. 24, 2023, has ended in a mistrial after seven days of juror deadlock.

Clancy's defense attorney, Kevin Reddington, claims she was suffering from postpartum psychosis when she strangled her children and attempted to take her own life. The prosecutors, Jennifer Sprague and Shanan Buckingham, argue that Clancy -- who pleaded not guilty to three counts of first-degree murder -- is criminally responsible for her children's deaths.

Judge William Sullivan, who is overseeing the trial, has set a court date of Sept. 29, 2026, to reconvene and determine next steps.

Watch a special edition of "20/20," "The Trial of Lindsay Clancy," airing Thursday, Sept. 4, at 9/8c on ABC, streaming the next day on Disney+ and Hulu.

Defense attorney Kevin Reddington speaks after mistrial declared

Reddington spoke to reporters moments after a mistrial was declared in Clancy's murder trial.

"It's a very sad case," he said, calling Clancy "a fantastic, wonderful individual."

Referring to the Plymouth County district attorney, he added, "Cruz knows he was crushed."

Asked about Clancy's current state of mind, Reddington said his client was "not good."

"She grieves the loss of those three children, Cora, Dawson and Callan," he said, naming Clancy's three deceased children.

Reddington then turned his attention to the lone juror he said prevented the jury from reaching a unanimous verdict, saying Clancy was "robbed."

"I hope that guy can sleep well at night," he said.

Reddington said he is prepared for a possible retrial.

Plymouth DA defends prosecution of Lindsay Clancy

Plymouth County District Attorney Timothy Cruz defended his prosecution of Clancy after Judge Sullivan declared a mistrial moments earlier, following seven days of jury deadlock. Cruz said the evidence and the law merited first-degree murder charges.

"Children were murdered, and it's our job to seek justice," Cruz said outside court. "This is a case of three children who died a violent death at the hands of the person who was supposed to love them the most."

He called the online treatment of the trial prosecutors, Buckingham and Sprague, "disgusting," noting they are both mothers themselves.

He lamented that "criminals are being treated as victims, and victims are invisible."

Cruz declined to announce an immediate decision about retrying Clancy.

The comments come moments after Sullivan declared a mistrial, following a decision by a single Massachusetts Supreme Judicial Court justice denying the defense's emergency stay petition, which asked the court to compel the jury to continue deliberations or remove a lone holdout it claimed was biased against the defendant.

Judge declares mistrial after justice declines to impose emergency stay

Sullivan has declared a mistrial after the jury said repeatedly it was unable to reach a verdict.

"I'm going to declare the jury is deadlocked, and I'm going to declare a mistrial," Sullivan said.

One juror appeared upset and put her head in her hands. Others look frustrated or defeated.

The decision comes after a justice of the Massachusetts Supreme Judicial Court declined to impose an emergency stay filed by Clancy's defense attorney.

Reddington asked again for Sullivan to inquire of the holdout juror, but the judge declined.
