Medical examiner gives graphic testimony in Lindsay Clancy murder trial

Jurors in the Lindsay Clancy murder trial heard State Medical Examiner Dr. Kimberly Springer detail the autopsies and fatal neck wounds of the three children as prosecutors used the testimony to sharpen the medical timeline in Plymouth Superior Court. The graphic evidence was introduced during the eighth day of testimony on Thursday, with autopsy photos shown to the jury in a case built around competing claims about Clancy’s mental state in the hours before and after the killings.

Clancy, 35, of Duxbury, is charged with killing her children in January 2023: Cora, 5, Dawson, 3, and Callan, 8 months. She has pleaded not guilty to three counts of murder. Her lawyers say she was suffering from severe postpartum depression and postpartum psychosis, and some trial coverage has described an insanity defense theory. Springer’s testimony, centered on the medical findings, gave jurors a more concrete account of how the deaths occurred and what the injuries showed about the sequence of events.

The testimony was visibly hard on the courtroom. Coverage from the day described Clancy sobbing as Springer discussed her youngest child’s autopsy and the fatal neck wounds, while jurors also reacted emotionally to the photos and testimony. Prosecutors have made clear throughout the trial that the medical evidence is not just about cause of death, but about what it can establish for jurors weighing intent, timing and responsibility.

The medical examiner’s appearance came after earlier testimony from Patrick Clancy, the children’s father and Lindsay Clancy’s ex-husband, who described the day the children were killed and the couple’s deteriorating mental health situation. A psychiatrist also testified that Lindsay Clancy was “calm and cooperative” days after the killings. First responders described what they found after being called to the Duxbury home, adding to a record that has now included a visit by jurors to the former family house and other locations tied to the night of the killings, including a CVS and a restaurant associated with Patrick Clancy’s movements.

The trial has drawn intense attention because it turns on whether a severe psychiatric episode can negate criminal responsibility in one of the state’s most closely watched child-killing cases. The prosecution’s decision to bring Springer to the stand underscored the importance of medical evidence in testing that defense against the physical facts of the deaths.
