A mistrial is declared in the murder case against Lindsay Clancy. Here's what could happen next

The trial to decide if Lindsay Clancy was criminally responsible when she strangled her three children in 2023 ended in a mistrial Friday after jurors were unable to reach a consensus after weeks of conflicting testimony about her post-pregnancy mental health and seven days of deliberations.

What happens now?

Clancy, a 36-year-old former labor and delivery nurse, remains charged with murder and will continue to be held in a psychiatric hospital until the case is resolved. Attorneys on both sides have a few options when it comes to the next steps.

Judge William Sullivan set a hearing for Sept. 29. During that proceeding, defense attorney Kevin Reddington will likely ask the judge to declare Clancy not guilty. It’s a long shot move and very unlikely to succeed.

That hearing could also reveal whether prosecutors will move to put Clancy on trial for a second time. They could also choose to seek a plea deal or even drop the case entirely, though that option is unlikely.

Sullivan suggested that everyone involved in the case, from attorneys to witnesses to court administrators, would need to look at their calendars to find a suitable time for a new trial, if one is held.

Clancy doesn’t deny strangling her children at their home south of Boston, but says postpartum psychosis led to her actions. After the killings, her husband found her badly injured in the yard, where she landed after jumping from a second-story window. She was left paralyzed from the waist down.

Prosecutors argue she knew what she was doing.

Plymouth County District Attorney Timothy Cruz said there would not be an immediate decision about a second trial, but he emphasized that his goal was always “getting justice for those three little babies.”

“This case was about Lindsay Clancy and what she did … the cruel and calculated killing of three innocents,” Cruz said shortly after court ended on Friday. He later continued, “Children were murdered and it’s our job to seek justice.”

Still, prosecutors typically consider a lot of things when determining whether to retry a case, said New York Law School Professor Heather Ellis Cucolo, including the potential expense and the likely outcome.

“I know the prosecutor stated openly that he would not allow public opinion to sway his decision, which is accurate, but the prosecution serves the public,” Cucolo said. “If it is believed that justice must be served by another trial, that is something the prosecutor’s office will take into account and weigh very heavily.”

A conviction could mean life in prison for Clancy, while an acquittal might lead to confinement in a mental health facility.

Cucolo said the defense attorney will likely push for the charges to be dropped entirely, and might also be open to a plea deal.

“But if the prosecution chooses to move forward with a trial, there's no way to prevent that from happening,” Cucolo said.

Reddington said in court that he believed Clancy's constitutional rights were violated when the judge declined to remove one juror after the other jurors suggested that he was not following the judge's instructions on reasonable doubt. But a mistrial isn't subject to an appeal, Cucolo said, because it's not a final judgment.

The impact on family members is another consideration, said Randy Gioia, a Boston-based defense lawyer who formerly supervised public defenders across the state.

Gioia said prosecutors should not put Clancy through another trial. He said he accepts Reddington’s disclosure that Clancy was extremely close to an acquittal, based on a note presented to the judge by the jury foreperson.

“Why put everyone through the trauma again: 16 to 18 jurors, all the witnesses, Patrick Clancy,” Gioia said, referring to Lindsay Clancy’s former husband. “What’s to be served here when we’ve had a long trial and long deliberations? You don’t have a strong case. You almost lost the case.”

It's not clear exactly how the jury reached an impasse, but Reddington suggested that just one juror stood in the way of an acquittal, and said the other jurors were “robbed.”

“They know 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,” he said outside the courthouse. “You could see how defeated they were sitting there. I got a funny feeling they would have gone on for another week if they had to. So I hope that guy can sleep well at night.”

Jurors are under no obligation to speak to attorneys on either side of the case, but it's common for the attorneys to see if any are open to talking about their experience, Cucolo said. Prosecutors can then use any information they get to reassess and fine-tune their approach, she said, perhaps focusing more on specific evidence or witnesses.

David Meier, a lawyer who represents Patrick Clancy in a lawsuit over her mental health treatment, released a statement about the emotional burden of the case, saying “there will never be closure” from the loss of the children.

“The prospect of reliving this tragedy through another trial is extraordinarily painful — for Patrick, for his family, and for all of us,” Meier said.

The statement didn’t indicate whether Patrick Clancy would support a second trial.

Lindsay Clancy has also filed a lawsuit over her mental health treatment. A retrial would likely force those civil cases to be put on hold, Cucolo said.

“They would not be able to move forward for now because of concerns of possible Fifth Amendment violations,” Cucolo said, because anything Clancy says in a civil case could potentially be used against her in the criminal case. That means the lawsuits could remain in legal limbo for a year or more, she said.
