The murder trial of Lindsay Clancy ended without a verdict Friday after jurors spent seven days unable to agree on whether she was criminally responsible for the deaths of her three young children.
Judge William Sullivan declared a mistrial after the jury sent him a note saying they could not reach a unanimous decision. The development brought an emotional end to a case that had captivated the public for weeks and placed renewed attention on postpartum mental illness and the challenges faced by women seeking psychiatric care after childbirth.
Clancy, 36, has never denied killing her children — 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan — at the family’s Massachusetts home in January 2023. Her defense argued, however, that she was suffering from postpartum psychosis and was not criminally responsible for what she did.
Prosecutors disputed that explanation, maintaining that Clancy understood her actions and deliberately carried out the killings.
The case began with deeply emotional testimony from Patrick Clancy, Lindsay’s former husband and the children’s father.
Patrick told jurors about returning home after Lindsay had sent him out to pick up takeout and medication. Prosecutors argued that sending him away was part of a plan to leave herself alone with the children.
When Patrick returned, he said the house was strangely quiet. He noticed blood in the main bedroom and an open window before discovering Lindsay outside in the snow.
She had jumped from a second-story window after cutting herself and attempting to take her own life.
Jurors later heard the 911 call Patrick made. In the recording, he speaks with Lindsay before telling the dispatcher that he needs to check on the children.
What followed became one of the most emotional moments of the trial.
After finding his children in the basement, Patrick broke down and screamed, “She killed the kids!” as the dispatcher repeatedly tried to understand what had happened.
Throughout the trial, witnesses described a woman whose mental health had deteriorated dramatically in the months after Callan’s birth.
Lindsay’s mother, Paula Musgrove, her former mother-in-law Susan Clancy, her sister, friends and coworkers all testified about changes they had witnessed.
Susan Clancy, who had worked alongside Lindsay as a labor and delivery nurse, described her former daughter-in-law as a loving and devoted mother. But she also said Lindsay had become increasingly anxious, paranoid and suicidal.
According to Susan, Lindsay was struggling with insomnia, loss of appetite and overwhelming sadness and anxiety. She said Lindsay was repeatedly asking for help but did not appear to be getting better.
Musgrove similarly testified that her daughter had become afraid to sleep alone and increasingly paranoid. Lindsay also believed that the medications she was taking were “destroying her mind,” her mother said.
Those medications became a major focus of the defense.
Lindsay sought help from multiple medical professionals and eventually admitted herself to a psychiatric hospital. Her attorney, Kevin Reddington, argued that the care she received was inadequate and that she had been misdiagnosed and overmedicated.
During questioning of psychiatrist Dr. Jennifer Tufts, Reddington challenged the decisions surrounding Lindsay’s prescriptions and questioned the use of brief telehealth appointments for someone experiencing serious mental-health symptoms.
At one point, he suggested that the treatment process had become little more than a box-checking exercise.
Tufts defended her treatment, telling jurors that she had tried to reassure Lindsay that treatment options remained available and that there was still hope.
The defense’s central argument was that Lindsay’s mental state had progressed beyond ordinary depression or anxiety.
Clinical and forensic psychologist Paul Zeizel testified that Lindsay had described hearing a male voice telling her that she had no choice but to kill her children and then herself. Zeizel said he believed her severe mental illness prevented her from being responsible for her actions.
Prosecutors presented experts who reached a very different conclusion.
Forensic psychologist Kirk Heilbrun testified that he did not believe Lindsay had experienced the type of hallucination she described. He pointed to statements Lindsay made after the killings, including her account that she told each child, “Go to God, baby. Go to God.”
Heilbrun said those statements suggested Lindsay believed she and her children would ultimately be together in heaven.
FBI psychiatrist Dr. Gregory Saathoff also testified for the prosecution and told jurors that Lindsay had the ability to distinguish right from wrong.
When the evidence was complete, the attorneys delivered their final arguments.
Reddington showed jurors a photograph of the Clancy family appearing happy and another image of Lindsay in the hospital. He argued that the transformation between those two moments was connected to the medications she had been taking and the treatment she received.
“How does this turn into this?” he asked. “How? Because of the damn medicine and the lousy medical care that she got.”
Prosecutor Jennifer Sprague urged jurors not to let criticism of the mental-health system distract them from the question of criminal responsibility.
Sprague acknowledged that Lindsay was depressed, exhausted and struggling, but argued that she nevertheless made a deliberate choice to kill her children because they represented the one thing keeping her from ending her own life.
“She was depressed. She was exhausted. She was done. She didn’t want to try anymore,” Sprague told jurors. “But those kids, those kids were her protective factor.”
After closing arguments, the jury began deliberating.
By Tuesday, jurors reported that they could not reach a unanimous decision. Judge Sullivan instructed them to continue. The following day, they again indicated that they remained divided.
Then came another dramatic turn.
On Thursday, the jury foreperson told the judge that one juror was refusing to follow the court’s instructions concerning reasonable doubt. Sullivan questioned jurors individually in private before rereading his instructions and sending them back to deliberate.
On Friday, the seventh day of deliberations, the jury returned to the courtroom with the same conclusion: they could not agree.
Sullivan ultimately determined that he had no choice but to declare a mistrial.
The announcement produced an audible gasp inside the courtroom.
Reddington then asked for permission to pursue an emergency appeal to Massachusetts’ highest court. Sullivan gave him time to make the request, but the appeal was denied less than three hours later.
The mistrial was then formally declared.
Outside the courthouse, Reddington sharply criticized the juror he believed had prevented the rest of the panel from reaching a verdict favorable to Lindsay.
He accused the juror of effectively taking away weeks of the other jurors’ lives and preventing what he believed would have been an acquittal.
For Patrick Clancy and his family, however, the mistrial means the painful chapter may not be over.
Prosecutors said they would not immediately decide whether Lindsay Clancy will face another trial.
After more than seven weeks of testimony, the case has ended without an answer to the central question that brought everyone into the courtroom: whether Lindsay Clancy should be held criminally responsible for the deaths of her three children.
For now, that question remains unresolved.
