UNITED STATES – On Friday, a US judge declared a mistrial after a jury failed to reach a unanimous verdict in the case of Lindsay Clancy, the Massachusetts mother who strangled her three young children and claimed she was legally insane at the time due to postpartum psychosis.

Judge William Sullivan announced the mistrial in a Plymouth courtroom after seven days of deliberation, during which 11 of the 12 jurors reportedly favoured finding Clancy not guilty by reason of insanity. A single juror refused to join the majority, leaving the panel deadlocked as required for a unanimous criminal verdict in the United States.

“At this point, I’m going to declare that the jury is deadlocked and I’m going to declare a mistrial,” Judge Sullivan said.

Clancy (36) had acknowledged killing her children – Cora (5), Dawson (3) and Callan (eight months) – at the family home in Duxbury, Massachusetts, in January 2023. She pleaded not guilty by reason of insanity, testifying that she heard a voice ordering her to kill her children. Her defence team argued that postpartum psychosis, a condition medical experts say affects roughly one to two women per 1 000 births, rendered her unable to understand the wrongfulness of her actions.

Prosecutors rejected the insanity defence, contending that Clancy had carefully planned the killings and was fully aware of the consequences. Jurors were given the option of finding her guilty of first-degree murder, second-degree murder, manslaughter, or not guilty by reason of lack of criminal responsibility.

The trial

The trial drew national attention, featuring testimony from more than 80 witnesses – including psychiatrists, people close to Clancy and her ex-husband – and days of distressing accounts of her deteriorating mental health in the months before the killings.

Clancy’s lawyer, Kevin Reddington, argued during closing statements that his client had made repeated pleas for help before the murders but received “lousy medical care” from the doctors she consulted. After killing her children, Clancy cut her neck and wrists and jumped from a second-storey window in an apparent suicide attempt that left her paralysed from the waist down. She has attended court in a wheelchair.

Reddington lashed out at the lone holdout juror after the mistrial, telling reporters: “They were robbed by one man for whatever his agenda was. I hope that guy can sleep well at night.”

Plymouth County District Attorney Tim Cruz told reporters that prosecutors will decide “shortly” whether to retry the case before a new jury. Clancy will remain at a psychiatric institution in the meantime.

Had she been convicted of first-degree murder, the former nurse would have faced life in prison without the possibility of parole.

Dozens of women dressed in pink gathered at the courthouse in a show of support for Clancy and to draw broader attention to women’s health issues.

National reaction

The case has reignited a national debate over maternal mental health, drawing a reaction from President Donald Trump. “It’s a horrible tragedy,” Trump told reporters at the White House. “I assume there’s going to be another trial.”

The trial also revived memories of the case of Andrea Yates, the Texas mother who drowned her five children in 2001. Yates was initially convicted and sentenced to life in prison, but a 2006 retrial found her not guilty by reason of insanity and she was committed to a psychiatric hospital.
