The jury weighing Lindsay Clancy’s fate told the judge Tuesday that they had been unable to reach a unanimous verdict after more than 17 hours of deliberations.
Despite the announcement, Judge William Sullivan instructed the jurors to return to the deliberation room and continue working toward a decision.
The development came on the fourth day of deliberations in Clancy’s closely watched murder trial, which centers largely on her mental state when her three children died in January 2023.
Clancy, 36, is accused of killing her children — 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan — at the family’s home in Duxbury, Massachusetts.
She does not dispute that she killed the children. Instead, she has pleaded not guilty by reason of lack of criminal responsibility, with her defense arguing that she was experiencing postpartum psychosis and had been overmedicated at the time.
The jury is considering several possible verdicts, including first-degree murder, second-degree murder and manslaughter, as well as the defense’s argument that Clancy was not criminally responsible because of her mental condition.
After the jury informed Sullivan that it could not agree, the judge brought the jurors into the courtroom before directing them to resume deliberations.
The disagreement reflects the central battle that has dominated the trial: whether Clancy was suffering from a severe psychiatric disorder that prevented her from understanding the nature or wrongfulness of her actions, or whether she deliberately killed her children while depressed but mentally aware of what she was doing.
Prosecutors have maintained that Clancy was not psychotic when the killings occurred. In closing arguments, Assistant District Attorney Jennifer Sprague characterized Clancy as deeply depressed and exhausted rather than detached from reality.
“She didn’t want to try anymore,” Sprague said.
The prosecutor argued that Clancy’s children had served as a reason for her to keep going, describing them as her “protective factor.”
“Those kids were keeping her from ending her misery,” Sprague said. “So she had to remove the protective factor.”
The defense has offered a starkly different explanation.
Attorney Kevin Reddington argued that Clancy had sought professional help for postpartum mental health problems but was failed by the medical providers treating her. He told jurors that the combination of postpartum psychosis and medication left his client unable to fully understand what she was doing.
During his closing argument, Reddington said prosecutors had “ripped the soul out” of Clancy.
The case began in January 2023, when Patrick Clancy returned to the family’s Duxbury home and discovered his children after finding Lindsay outside following her jump from a second-story window.
The children were later pronounced dead.
Patrick testified during the lengthy trial and has since said that he has forgiven Lindsay, who is now his ex-wife.
The prosecution also called first responders, medical professionals, friends and family members to testify about Clancy’s behavior and mental health before and after the killings. Her mother, sister, friends and former in-laws were among those who took the stand.
After weeks of testimony and closing arguments, the case is now in the hands of the 12-person jury.
For the moment, however, there is no verdict.
With jurors reporting that they are divided after more than 17 hours of deliberations, the case could face further uncertainty if they remain unable to reach a unanimous decision.
