Mistrial Declared in Lindsay Clancy Murder Case
A Massachusetts judge declared a mistrial Friday in the murder case of Lindsay Clancy after jurors reported they could not reach a unanimous verdict following a week of deliberations. Clancy was charged with first-degree murder in the January 2023 deaths of her children, Cora, 5, Dawson, 3, and Callan, 8 months, at the family’s Duxbury home.
The trial focused on whether Clancy was criminally responsible when she strangled the children with exercise bands. Her attorneys argued that postpartum psychosis and other severe psychiatric symptoms prevented her from understanding the wrongfulness of her actions or controlling her conduct. Prosecutors countered that evidence of planning and purposeful behavior showed she remained legally responsible.
Jurors heard testimony about Clancy’s anxiety, depression, insomnia, medications and mental health treatment before the killings. A defense psychiatrist testified that Clancy reported hearing a male voice commanding her to kill the children and feeling controlled by an outside force. A prosecution expert questioned that account, noting she had not previously reported auditory hallucinations to treating professionals.
The mistrial came amid a defense claim that the jury was divided 11-1 and that a single holdout was not properly applying instructions on reasonable doubt. Defense attorneys sought emergency intervention from the Massachusetts Supreme Judicial Court to delay the mistrial and permit further inquiry, but the request was denied.
Plymouth County District Attorney Tim Cruz emphasized the deaths of the three children and the impact on their family. Because the proceedings ended without a verdict, Clancy was neither convicted nor acquitted. Prosecutors may retry the case, although they have not announced a decision. Judge William Sullivan said he wants any retrial held relatively soon. Clancy is scheduled to return to court Sept. 29 for a status hearing, trial assignment and consideration of a defense motion. Existing bail orders remain in effect.
