A Massachusetts judge declared [1] a mistrial Friday in the murder case against Lindsay Clancy after jurors failed to reach a unanimous verdict in the deaths of her three young children.
The panel had deliberated for roughly a week at Plymouth Superior Court before reporting that it remained hopelessly divided.
Judge William Sullivan ended the proceedings after an emergency defense appeal failed before the Massachusetts Supreme Judicial Court.
Justice Dalila Argaez Wendlandt denied the request, allowing Sullivan to formally close the trial without a conviction or an acquittal.
The final days featured a bitter fight over what defense attorneys described as an 11 to 1 split.
Attorney Kevin Reddington accused a lone male juror of refusing to properly follow the court’s reasonable doubt instructions despite allegedly expressing doubt about the prosecution’s case.
Outside the courthouse, Reddington sharply criticized the unidentified juror and said the remaining panel members appeared crushed by the outcome.
“So, I hope that guy can sleep well at night,” he told reporters after the mistrial was declared.
Plymouth County District Attorney Tim Cruz turned attention back toward the victims, 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan.
“It is our job to make sure the victims are not invisible,” Cruz said.
Cruz also spoke about the grief surrounding a case that has devastated an entire family.
“I am a father and a grandfather, and I cannot imagine the hell this entire family has lived through.”
Clancy was charged with first degree murder after her children were strangled with exercise bands inside the family’s Duxbury home in January 2023.
Authorities said her husband, Patrick Clancy, discovered her seriously injured outside after returning from errands.
Investigators found the three children inside the house.
Cora and Dawson died that night, while Callan was transported to a hospital and died several days later from his injuries.
Clancy survived after jumping from a second story window, but her injuries left her paralyzed and using a wheelchair.
WATCH:
The central question at trial was not whether she caused the deaths, but whether she could legally be held criminally responsible for her conduct.
Her attorneys argued that postpartum psychosis and severe mental illness prevented her from understanding the wrongfulness of her actions or controlling her behavior.
Under Massachusetts law, prosecutors were required to prove beyond a reasonable doubt that she remained criminally responsible once that defense was properly raised.
Prosecutors countered with evidence they said demonstrated planning, awareness and purposeful conduct before, during and after the killings.
They argued that Clancy deliberately arranged an opportunity to be alone with the children while Patrick left to buy children’s medicine and pick up dinner.
The defense contended that Clancy heard a male voice ordering her to kill the children.
Forensic psychiatrist Dr. Phillip Resnick testified that she described losing control of her own body, saying, “It was almost like she was a puppet, and someone else was pulling the strings.”
Prosecution expert Gregory Saathoff challenged that account as “very unusual.”
He testified that Clancy had never previously reported hearing voices to psychiatrists, nurse practitioners, physicians, emergency department workers or staff members at McLean Hospital.
Saathoff also questioned why the alleged voice reportedly stopped after the youngest child was strangled.
Prosecutors presented that detail as another reason jurors should reject the defense account and find that Clancy acted with conscious intent.
Jurors heard extensive testimony about Clancy’s anxiety, depression, insomnia, psychiatric treatment and prescription medications before the killings.
Family members said they had become deeply concerned about her condition during the closing months of 2022, though they also described her as a nurturing mother.
In one October 2022 message to her mother, Clancy pleaded for someone to stay with her because she felt sick, frightened and unable to face the day alone.
The defense used those communications to argue that her psychiatric decline had been visible months before the children died.
The mistrial leaves prosecutors free to bring the case before another jury.
Cruz has not yet announced whether his office will pursue a second trial, but Sullivan said he wants the case retried “sooner rather than later.”
Clancy is scheduled to return to court on Sept. 29 for a status hearing, possible trial assignment and consideration of a defense Rule 25 motion.
For now, the case remains unresolved, and three murdered children remain at the center of a courtroom battle that produced no final verdict.
