The Lindsay Clancy mistrial was declared Friday after jurors failed for a third time to reach a unanimous verdict in the Massachusetts murder case. The decision leaves all charges pending and produces neither a conviction nor an acquittal.

Judge William Sullivan ended the trial on Sept. 4 after the panel deliberated for seven days, following a trial that lasted nearly six weeks, NBC News and the BBC reported.

Clancy, 36, has pleaded not guilty to three counts of first-degree murder in the 2023 deaths of her children, Cora, 5, Dawson, 3, and Callan, 8 months. The central issue for the jury was whether she was criminally responsible at the time of the deaths.

Her lawyers have argued that she was experiencing postpartum psychosis and should not be held criminally responsible. Prosecutors argued that the killings were intentional and that she knew right from wrong, according to CNN and NBC News.

What does the Lindsay Clancy mistrial mean?

A mistrial means the jury did not return a verdict, so it does not decide whether Clancy is guilty or not guilty. The case remains unresolved, and Clancy remains charged and held at a mental-health facility, the BBC reported.

The deadlock capped a tense final day. The defense alleged that a juror was not following the court’s instructions on reasonable doubt and sought emergency intervention from the Massachusetts Supreme Judicial Court.

The defense asked for further questioning or removal of that juror. That allegation was not a judicial finding. A justice on the state’s highest court denied the request, clearing the way for Sullivan to formally declare the mistrial, NBC News and CNN reported.

What happens next in the Lindsay Clancy case?

Plymouth County District Attorney Timothy Cruz must now decide how to proceed. Prosecutors may seek a new trial before a different jury, potentially on first-degree murder or lesser charges, pursue a plea agreement or take another course, according to NBC News, the BBC and The Guardian.

No decision on a retrial was reported Friday. The court has scheduled a status hearing for Sept. 29, when the parties can address the next steps.

The mistrial followed more than 40 hours of deliberations over seven days, the BBC reported. Jurors had sent the judge three messages saying they could not agree on a verdict.
