Lindsay Clancy Update: What Does a Mistrial Mean, What Happens Next and Could She Face a New Trial?

A Massachusetts judge declared a mistrial in Lindsay Clancy’s triple-murder case Friday after jurors failed to reach a unanimous verdict, ending more than 38 hours of deliberations over seven days. The 12-member panel repeatedly told Judge William Sullivan it was deadlocked, with the final note expressing regret that it could not agree after a tense, closely watched week in court.

The decision followed an emergency appeal by Clancy’s defense to the Massachusetts Supreme Judicial Court. Her lawyers argued that a possible holdout juror was refusing to properly apply the law on reasonable doubt. The court rejected the request, clearing the way for Sullivan to end the trial without a verdict.

Following the mistrial, Donald Trump reacted, saying, “It’s a terrible situation,” Trump said Sept. 4 during an Oval Office event. “Look, she did a horrible, horrible thing. Can’t be worse. But you’ll find out what the price to pay is, there’ll be a price.”

What Does Mistrial Mean?

A mistrial ends a trial without a verdict. It is neither a guilty verdict nor an acquittal. Here, jurors could not unanimously decide whether Clancy was criminally responsible for killing her three children, Cora, 5, Dawson, 3, and Callan, 8 months, in January 2023.

Sullivan had already given the jurors additional instructions, including a Tuey-Rodriguez, or “dynamite,” charge, urging them to reconsider their positions without abandoning their honest beliefs.

Why Was It Declared?

The jury’s deadlock was the immediate reason. Jurors sent notes saying they could not reach a unanimous decision on Tuesday, Wednesday and Thursday before returning with a final note Friday.

The situation became more complicated Thursday when the foreperson reportedly said one juror was refusing to follow instructions on reasonable doubt. Clancy’s attorney, Kevin Reddington, asked Sullivan to question or remove that juror.

Sullivan declined. He questioned all 12 jurors individually about whether they could follow his instructions and then repeated the legal guidance on reasonable doubt. He said it was inappropriate to take sides between one juror and the other 11.

On Friday, Reddington sought emergency intervention from the state’s highest court, asking it to prevent a mistrial and allow further inquiry into the disputed juror. Associate Justice Dalia Argaez Wendlandt heard arguments by Zoom and later rejected the defense request. Sullivan then formally declared the mistrial.

What Happens Next?

The mistrial essentially returns the case to its pretrial status. Clancy remains charged and is being held at a psychiatric hospital while prosecutors decide how to proceed.

Prosecutors can seek a retrial with a new jury. If they do, jury selection would begin again. Reddington has said his team is prepared for another trial.

Prosecutors could also negotiate a plea agreement with Clancy. They could also dismiss the charges, although that appears less likely. A status conference is scheduled for September 29, when the court is expected to address the next steps.

Could She Be Acquitted?

Yes, but the mistrial itself is not an acquittal. A new jury could acquit Clancy if the defense persuades jurors that prosecutors failed to prove criminal responsibility beyond a reasonable doubt.

The first jury could have convicted Clancy of first-degree murder, second-degree murder or manslaughter, found her not guilty, or found her not criminally responsible because of mental illness.

Clancy does not dispute that she killed her children. Her defense argued that she was suffering from severe postpartum psychosis and therefore should not be held criminally responsible. Prosecutors argued that she understood what she was doing and deliberately planned the killings.

What Could Happen?

The five-week trial featured testimony from more than 80 witnesses and centered on a narrow but crucial question: whether Clancy understood the wrongfulness of her actions. Her defense presented postpartum psychosis as the reason she should not be held criminally responsible, while prosecutors argued that she was suicidal but knew what she was doing and planned the killings. A court hearing is set for September 29.

A retrial is the most significant possibility, but no final decision has been announced. If prosecutors retry Clancy, the outcome could again be a conviction, an acquittal or another deadlocked jury.

If convicted of first-degree murder, Clancy could face life imprisonment without parole. A verdict of not guilty by reason of lack of criminal responsibility would be different from an ordinary acquittal and could result in psychiatric commitment rather than immediate freedom.

For now, there is no verdict because the jury could not reach one. The mistrial gives prosecutors another decision to make: try the case again, negotiate a resolution or walk away from the charges.
