Jury deliberates in Lindsay Clancy case as defense, prosecution clash over psychosis claim

The jury in Plymouth Superior Court now holds the fate of Lindsay Clancy, a 36-year-old Massachusetts woman who admits to killing her three children but denies criminal responsibility for their deaths. After 22 days of testimony, the case has been handed to twelve jurors tasked with answering a question that has divided expert psychiatrists: whether Clancy was so consumed by psychosis on January 24, 2023, that she could not distinguish right from wrong.

Clancy killed her children—Cora, 5, Dawson, 3, and Callan, 8 months old—in their Duxbury home. She then slit her wrists and throat, and jumped from a window, breaking her neck. The fall left her paralyzed. Her defense argues she was overmedicated and suffering from postpartum psychosis, a severe mental illness that rendered her incapable of criminal intent. Prosecutors counter that she planned the murders methodically and faked her suicide attempt to escape accountability.

The trial centered almost entirely on Clancy's mental state in the weeks and days before the killings. Her husband Patrick testified that he found the house unusually quiet when he returned from running errands she had requested. He discovered blood "sprayed, almost like with a hose" throughout the bedroom, an open window, and his wife on the ground with deep cuts on her wrists and neck. When he asked where the children were, she told him they were in the basement but gave no indication they were in danger. He ran downstairs and found all three children. He attempted CPR before first responders arrived.

First responders described a chaotic scene. Officer Brian Josephine testified that when Patrick Clancy saw the officers in the basement, he "looked up and screamed 'She killed the f-----g kids.'" Fire captain and paramedic PJ Hussey said things "turned very chaotic very quickly" as more resources arrived on scene.

Clancy's diary entries, read aloud during trial, revealed a woman drowning in despair. In November 2022, she wrote that she felt like she was "drowning every day" managing her youngest child's sleep schedule. She described "horrible insomnia and anxiety which is causing depression," "crazy brain fog," and feeling "completely disconnected" from her baby. "I don't know what's wrong with me," she wrote. "I want help. I want to be well." Yet Dr. Jennifer Tufts, her treating psychiatrist, testified that the day before the murders, Clancy "completely" denied any suicidal or homicidal thoughts and showed "no signs of psychosis or mania." Tufts did not recommend hospitalization.

The psychiatric testimony became the trial's battleground. Dr. Avram Mack, a forensic psychiatrist called by prosecutors, said Clancy knew right from wrong at the time of the killings and retained "the capacity required for having criminal responsibility." He acknowledged she suffered from depression and anxiety but saw no evidence of psychosis or mania caused by her medications. Dr. Phillip Resnick, a forensic psychiatrist who testified in the Andrea Yates case—a Texas mother who drowned her five children in 2001 and was acquitted on retrial due to postpartum psychosis—offered a starkly different assessment. Resnick testified that Clancy "was clearly psychotic on that day" and was under the influence of a "command hallucination." He said she believed her body was "taken over by an external force" and that she was "like a puppet and someone else was pulling the strings."

Clancy told both her husband and Dr. Paul Zeizel, a clinical psychologist who met with her after hospitalization, that she heard a male voice ordering her to kill her children. According to Zeizel, she said the voice told her "she didn't have any choice but she had to kill her children and then kill herself." Patrick Clancy recalled a similar account: the voice told her "if she didn't do it now, she would lose her chance." Dr. Mack said Clancy described the murders themselves, saying out loud during the killings, "Go to God."

Family members testified that Clancy had been reaching out for help. Her mother, Paula Musgrove, recalled her daughter sending texts asking her to stay the night and expressing concern about her medications. Clancy's sister Allison Ozga said that in November 2022, Clancy "did not look good, her energy wasn't high," and a month later told her she was in "a really tough spot." Yet when Ozga asked if she was safe, Clancy said yes. Clancy's former coworker Margaret Hamp testified that Clancy had been shocked to learn about the Andrea Yates case and had asked, "How could a mother hurt her children?"

In closing arguments on August 27, defense attorney Kevin Reddington argued that prosecutors had manipulated evidence and that medical practitioners had failed Clancy through overmedication. "My God, what does she have to do? She was reaching out for help and she was not getting it," he said. At least two jurors wept. Prosecutor Jennifer Sprague countered that while Clancy was mentally ill, the jury's task was to determine whether she could distinguish right from wrong. She pointed to Clancy's behavior before the murders—including looking up how long Patrick's errands would take—as evidence of planning and rational capacity. The jury now must weigh these competing narratives and decide what criminal responsibility means when the mind itself has fractured.
