Lindsay Clancy Murder Trial Set for Mistrial After Jury Deadlocks

A judge is set to declare a mistrial in Lindsay Clancy’s murder trial after jurors failed to reach a unanimous verdict following seven days of deliberations.

According to the New York Post, the 12-person jury, made up of nine women and three men, told Judge William Sullivan that it could not agree on whether to convict Clancy, 36, of three counts of first-degree murder.

The judge said Friday that he had no choice but to declare a mistrial after the panel repeatedly reported that it remained deadlocked.

“It is with a heavy heart that we will not be able to come to unanimous decision,” Sullivan said while reading the jury’s third note indicating an impasse.

Before Sullivan could formally bring the jurors into the courtroom, defense attorney Kevin Reddington asked for additional time to seek an emergency stay blocking the mistrial. Sullivan gave him one hour to request a stay from Massachusetts’ highest appeals court.

The jury had first reported that it was deadlocked on the fourth day of deliberations, after nearly 18 hours. A second note followed after almost 28 total hours, prompting Sullivan to issue a Tuey-Rodriguez instruction directing jurors to continue working toward a unanimous decision.

The case centers on the deaths of Clancy’s three children: Cora, 5, Dawson, 3, and 8-month-old Callan. Prosecutors accused Clancy of carefully planning the killings, while her defense argued that she was experiencing postpartum psychosis and hallucinated a voice commanding her to kill the children and herself.

The defense presented testimony about Clancy’s deteriorating mental health after Callan’s birth, including psychiatric treatment, suicide hotline calls and a five-day hospitalization. Patrick Clancy testified that she had told him about thoughts of harming the children and that she “kept getting worse and worse.”

Prosecutors offered a sharply different account, pointing to evidence they said showed planning and intent. They also cited Google searches, including “How to slit throat to die,” made before the killings.

If the mistrial stands, Clancy will remain in custody at Tewksbury Hospital while the Plymouth County District Attorney’s Office determines its next move. Prosecutors could seek a second trial, pursue a plea agreement or drop the charges.

Reddington has previously said Plymouth District Attorney Timothy Cruz could reduce the charges to second-degree murder if the case is retried. He has also said Cruz is likely to pursue another trial.

The trial lasted nearly five weeks and included 21 days of testimony from roughly 85 witnesses. Expert witnesses gave conflicting opinions about Clancy’s mental state, with defense psychiatrist Dr. Phillip Resnick arguing that a command hallucination drove her actions, while prosecution experts said her conduct showed that she understood what she was doing was wrong.

The case has drawn national attention to postpartum mental health and criminal responsibility, with supporters and opponents gathering outside the courthouse during the proceedings.
