The murder trial of Lindsay Clancy entered its tenth day with defense attorneys beginning their cross-examination of Dr. Jennifer Tufts, a psychiatrist who treated Clancy in the months leading up to the deaths of her three children. Clancy is accused of strangling her children, five-year-old Cora, three-year-old Dawson, and eight-month-old Callan, in their Duxbury, Massachusetts, home in January 2023.

Dr. Tufts began treating Clancy four months before the killings and prescribed her a regimen that included thirteen different psychiatric medications, including Seroquel, Trazodone, Ativan, and Valium. Both Lindsay Clancy and her husband, Patrick Clancy, have filed separate malpractice lawsuits against Dr. Tufts and other providers, alleging that Clancy was overmedicated for postpartum mental health issues. These lawsuits claim that the overmedication exacerbated her condition and ultimately led to the children's deaths.

During the trial, mental health professionals, counselors, psychiatrists, and medication experts have testified about Clancy's treatment. The defense argues that Clancy suffered a severe psychotic mental break due to undiagnosed postpartum depression and the effects of her medications. Conversely, the prosecution contends that Clancy's actions were deliberate and premeditated, and that the low levels of drugs found in her blood did not cause cognitive impairment or psychosis.

Last week, the trial saw a courtroom clash when defense attorney Kevin Reddington accused the prosecution of a hot mic incident. Reddington alleged that prosecutors were heard saying "shut her up" while Clancy was audibly weeping as autopsy photos of her son Callan were shown to the jury. The medical examiner who performed Callan's autopsy, Dr. Kimberley Springer, had previously testified, and graphic images were displayed. Clancy had broken down in sobs at the defense table during this testimony.

Clancy has pleaded not guilty to the charges. The proceedings are taking place at Plymouth County Superior Court.
