The closely watched trial of Lindsay Clancy, the Mᴀssachusetts mother accused of killing her three young children in 2023, ended without a verdict after jurors were unable to reach a unanimous decision.

Clancy was charged with three counts of first-degree murder in connection with the deaths of her children, Cora, 5, Dawson, 3, and Callan, 8 months. The children were found at the family’s home in Duxbury, Mᴀssachusetts, in January 2023. Clancy survived a suicide attempt after the incident and has remained in medical care while the case moved through the courts.

The trial lasted several weeks and included extensive testimony about Clancy’s mental state before and during the killings. Her defense acknowledged that she was responsible for the children’s deaths but argued that she should not be held criminally responsible because she was experiencing severe postpartum psychosis. Defense attorneys also argued that medications she had been prescribed in the weeks before the tragedy contributed to her deteriorating condition.

Prosecutors presented a different interpretation of the evidence. They argued that Clancy understood what she was doing and had the ability to make decisions and carry out ordinary activities around the time of the killings. Their case focused on her behavior before and after the deaths, as well as testimony from medical and psychiatric experts.

More than 80 witnesses reportedly testified during the trial, including Clancy’s former husband, Patrick. He described the family’s circumstances and his interactions with Clancy before discovering the children at their home. The jury also heard from psychiatric experts on both sides who examined the question of whether Clancy’s mental illness prevented her from understanding the wrongfulness of her actions.

The defense and prosecution delivered their closing arguments on August 27. Prosecutors urged jurors to focus on the evidence and determine whether Clancy was legally responsible for the deaths. The defense, meanwhile, emphasized the severity of the psychiatric symptoms it said she was experiencing and asked jurors to find her not guilty by reason of lack of criminal responsibility.

The jury then began deliberations, but the process continued for days without a resolution. By early September, jurors had indicated that they were struggling to reach an agreement. After seven days of deliberation, the court ultimately declared a mistrial on September 4 because the jury remained ᴅᴇᴀᴅlocked. Reports indicate that 11 jurors favored finding Clancy not guilty by reason of lack of criminal responsibility, while one juror did not agree with that conclusion.

Because there was no unanimous verdict, Clancy was neither convicted nor acquitted at the end of the trial. The case therefore remains unresolved.

Her defense team has since asked the judge to enter a not-guilty verdict rather than send the case to another jury. Attorney Kevin Reddington filed a motion arguing that the evidence presented by prosecutors was insufficient to establish criminal responsibility and that Clancy should be found not guilty by reason of insanity. The motion is scheduled to be considered by Judge William Sullivan at a September 29 hearing.

The prosecution has not publicly announced whether it intends to retry Clancy. A second trial remains legally possible, but the defense is seeking to prevent that from happening through its post-mistrial motion.

The case has also generated broader discussion about postpartum psychosis and access to mental-health care for new mothers. Following the mistrial, Mᴀssachusetts Gov. Maura Healey proposed additional state funding for postpartum health services, including expanded home visits and broader screening for perinatal mental-health conditions. The proposal includes $2 million for the state’s Welcome Family program and additional funding for a maternal mental-health support initiative.

For the families involved, the mistrial means the legal process surrounding the deaths of the three children is not yet over. Clancy remains in a psychiatric facility while the court considers the next steps. The September 29 hearing is expected to be important in determining whether the case moves toward another trial or whether the judge considers the defense request to resolve the charges without a retrial.

The case has left unresolved questions surrounding Clancy’s mental state, the competing medical interpretations presented at trial and the legal standard for criminal responsibility. What happens next will depend on the judge’s ruling and any decision by prosecutors regarding further proceedings.
