The defense has rested its case in Lindsay Clancy’s triple-murder trial after four weeks of testimony centered on her mental health and claims of postpartum psychosis.
Clancy, 36, does not deny killing her three children — Cora, 5; Dawson, 3; and Callan, 8 months — at their Duxbury, Massachusetts, home in January 2023. Her defense argues she should not be held criminally responsible because she was suffering from postpartum psychosis during a severe mental health crisis.
The defense called 10 witnesses, including mental health professionals who testified that Clancy was psychotic when she killed her children and attempted suicide, leaving her partially paralyzed.
Forensic psychiatrist Dr. Phillip Resnick, the defense’s final witness, testified that Clancy was “frankly psychotic” at the time of the killings. He supported her account that she heard a male voice ordering her to kill her children and herself.
“Not only did she hear a command, but she felt that her body was taken over by an external force,” Resnick testified. “It was almost like she was a puppet and someone else was pulling the strings.”
Prosecutors have strongly disputed that account. They argue Clancy killed her children “deliberately and meticulously” and remained capable of understanding right from wrong.
Prosecution witnesses have also testified that Clancy retained control over her actions despite suffering from depression and other mental health problems.
Defense Experts Describe Psychosis
Clinical and forensic psychologist Paul Zeizel testified that Clancy was experiencing psychosis and could not understand the wrongfulness of her actions.
He said Clancy told him she heard a male voice ordering her to kill her children and then herself. Resnick similarly testified that Clancy believed she had no choice but to follow the command.
The defense experts described symptoms Clancy experienced before the killings, including severe insomnia, dissociation, intrusive thoughts, emotional detachment and fears that others could hear her thoughts.
Prosecutors, however, emphasized that Clancy had never reported hearing the male voice to her doctors before the killings and did not tell providers that she was having thoughts about harming her children.
Loved Ones Recall Her Declining Mental Health
Several witnesses described Clancy as a loving mother and dedicated labor and delivery nurse whose mental health deteriorated in late 2022.
Her mother, Paula Musgrove, testified that Clancy began experiencing serious problems after the birth of her third child. She sought treatment for anxiety, insomnia and other symptoms and was prescribed multiple psychiatric medications.
Musgrove said Clancy eventually became increasingly paranoid, struggled with her memory and repeatedly told her, “This isn’t me, I’ve never been like this before.”
Clancy’s former mother-in-law also described her as “begging for help.”
Prosecution Begins Rebuttal
The prosecution’s rebuttal has focused on challenging the insanity defense.
Psychiatrist Dr. Avram Mack testified that Clancy was experiencing a major depressive episode in January 2023 but still had the ability to understand right from wrong and control her behavior.
Mack pointed to Clancy’s reported statement, “Go to God,” while strangling her children and her reaction after waking in the hospital. He said both indicated that she understood the wrongfulness of what she had done.
Chaplain Sheila Cavanaugh, who has met with Clancy more than 200 times at Tewksbury Hospital, testified that Clancy continues to grieve her children and speaks about them frequently.
The trial is now approaching its final stage. After rebuttal testimony, the parties are expected to deliver closing arguments before the jury decides whether Clancy was criminally responsible for the deaths of her three children.
If convicted of murder, Clancy could face life in prison. If found not criminally responsible by reason of insanity, she would likely face commitment to a psychiatric hospital.
