Psychiatrist Leaves Hospital After Testimony
Dr. Avram Mack, the prosecution psychiatrist who testified that Lindsay Clancy was criminally responsible for the deaths of her three children, is no longer employed by Nemours Children’s Health in Delaware. According to the New York Post, Mack resigned Monday, the same day he finished his testimony in the closely watched Massachusetts murder case. The hospital system told the outlet Friday that Mack was no longer employed there, but declined to give further details, saying employment decisions are confidential. Nemours has not publicly connected his departure to his testimony, though the timing has drawn attention for obvious reasons.
A Tragic Case Centered on Criminal Responsibility
Mack was called as a prosecution rebuttal witness after evaluating Clancy twice in April 2026, more than three years after the deaths of Cora, 5, Dawson, 3, and eight-month-old Callan inside the family’s home in Duxbury, Massachusetts. Clancy’s lawyers do not dispute that she killed the children on January 24, 2023. Their argument is that she was suffering from postpartum psychosis and was not criminally responsible for what happened. Mack acknowledged that Clancy was in “a serious psychiatric state” and “was suffering,” but he also testified that he found no psychotic features in her records and believed she still had the capacity to understand the killings were wrong.
Defense Pressed Hard in Court
Defense attorney Kevin Reddington repeatedly challenged Mack’s qualifications, his experience treating adults, his grasp of postpartum psychiatric disorders, and the conclusions he reached about Clancy’s state of mind. The questioning grew especially tense when Mack appeared to smile while discussing psychological testing. Reddington snapped, “What are you smiling for?” and then added, “This is not funny, sir.” Judge William Sullivan stepped in more than once as the exchange became contentious, telling Mack, “Doctor, please,” and instructing him to listen carefully and answer the question being asked.
Experts Split Over Her Mental State
Mack’s testimony stood in direct conflict with defense expert Dr. Phillip Resnick, who concluded that Clancy was experiencing postpartum psychosis, delusions, and command hallucinations when she killed the children. Mack testified that Clancy told him she heard a loud male voice ordering her to kill the children so she could then kill herself. He also said Clancy remembered strangling the children and telling each of them to “go to God.” Mack argued that this statement did not prove she was unaware of what she was doing, but instead showed she understood the children were innocent. He maintained that even severe mental illness, including psychosis, does not automatically mean a person cannot know right from wrong.
Jury Deliberations Continue
During closing arguments, Plymouth County Assistant District Attorney Jennifer Sprague pointed jurors back to the prosecution’s claim that Clancy deliberately separated the children and killed them one by one. Speaking about three-year-old Dawson, Sprague said, “She knew that he might struggle, and so it made sense rationally to remove him and separate him first and kill him first.” One female juror was reportedly brought to tears during the prosecution’s closing argument. The jury ended its second day of deliberations Friday without a verdict and is scheduled to return Monday. Clancy, 36, faces three counts of first-degree murder and could spend the rest of her life in prison if convicted. If she is found not guilty by reason of insanity, she could be committed to a psychiatric facility until authorities determine she no longer poses a danger.
