PLYMOUTH, Mass. — The defense team for Lindsay Clancy continued calling witnesses on Tuesday as the high-profile murder trial enters its 15th day of testimony in Plymouth Superior Court.
Clancy, a former Duxbury mother charged in the 2023 deaths of her three young children, is pursuing an insanity defense. Her attorney, Kevin Reddington, is working to show jurors how her mental health deteriorated in the months leading up to the killings, with a particular focus on the medications she was prescribed and their reported effects.
Dr. Paul Zeizel, a psychologist, told the jury he’s seen Clancy 45 times since the incident and let Clancy call her husband while she was hospitalized.
Zeizel said on speaker phone, Clancy told Patrick she heard a male voice telling her she had no choice but to kill the children and kill herself.
Court resumes with cross-examination of Zeizel on Wednesday morning.

What happened Monday
After prosecutors rested their case Monday, the defense began calling family members to the stand. Jurors first heard testimony from Clancy’s mother, Paula Musgrove, who described significant changes in her daughter’s behavior following the birth of her third child in 2022.
Musgrove testified that Clancy initially appeared happy after giving birth but later became increasingly anxious about returning to work at Massachusetts General Hospital. According to her testimony, Clancy reached out for help in late October 2022, telling her mother she was “really sick” and that something was wrong.
Musgrove also told jurors that Clancy frequently complained about the medications she was taking, saying they affected her memory and mental state.
During testimony, Musgrove recounted Clancy telling her that the medication was “destroying her mind” and that she wanted to feel better and enjoy time with her children again.
Jurors also heard from Clancy’s sister, Allison Ozga, who testified that she noticed troubling changes in Lindsay around Thanksgiving 2022. Ozga said she felt something was wrong and asked her sister whether she was safe. According to her testimony, Lindsay responded that she was.
One of the most significant moments of Monday’s testimony came when Musgrove told jurors that, about a month before the killings, Clancy disclosed that she was experiencing thoughts of harming her children.
