Lindsay Clancy, the Massachusetts mother accused of strangling her three young children in January 2023, heard a male voice tell her she had a final chance to kill the kids and herself, according to expert testimony delivered Friday during trial proceedings in Plymouth County Superior Court. The defense rested in the high-profile triple-murder trial as the case nears its conclusion.
Psychiatrist Testifies on Rebuttal Regarding Clancy’s Mental State
Testifying as a prosecution rebuttal witness, psychiatrist Dr. Avram Mack told the 18-person jury about statements Clancy made regarding the night of the killings, according to reporting from the New York Post. Mack testified that Clancy told him a male voice instructed her, “You should kill the kids. This is your last chance so you can kill yourself.”
During cross-examination, defense attorney Kevin Reddington questioned Mack extensively about his medical background and his direct experience with pregnant women and postpartum psychosis, according to the New York Post. Mack acknowledged to the court that in his career he had worked directly with roughly 10 women experiencing postpartum psychosis. Mack further testified that Clancy acted methodically during the incident, which he argued demonstrated an underlying mental capacity to understand that her actions were wrong.
Defense Arguments and Family Testimony
Clancy, 36, does not deny that she fatally strangled her three children—Cora, 5, Dawson, 3, and 8-month-old Callan—using exercise bands in the basement of the family’s Duxbury home on January 24, 2023, according to reporting by CNN. However, her defense team argues she is not criminally responsible for the deaths because she suffered from severe, undiagnosed postpartum psychosis and bipolar disorder, which they contend was intensified by a regimen of psychiatric medications.
Earlier in the trial proceedings, Clancy’s mother, Paula Musgrove, testified about her daughter’s mental health decline in the months leading up to the tragedy, according to CNN. Musgrove described Clancy as a loving mother who repeatedly expressed distress over her changing mental state, quoting her daughter as saying, “This isn’t me, I’ve never been like this before.” Additional testimony from former colleagues detailed Clancy’s dedication as a labor and delivery nurse before her mental health deteriorated.
Trial Timeline and Next Steps
The Plymouth County Superior Court judge dismissed the jury for the weekend following Friday’s testimony, as reported by the New York Post. Closing arguments in the trial are scheduled to begin early next week. If convicted on three counts of murder, Clancy faces a sentence of life imprisonment without the possibility of parole. If the jury finds her not criminally responsible by reason of mental illness, she faces commitment to a psychiatric facility.
