New details about a prosecution psychiatrist involved in the Lindsay Clancy trial have emerged after a tense exchange in court. Just after Dr. Avram Mack testified, multiple outlets reported that he was “no longer employed” at his former workplace, Nemours Children’s Health. Mack worked in the behavioral health department of the Delaware children’s hospital.
According to a report from WCVB, the hospital claimed that his testimony for the trial had no direct relationship to his work at the hospital and was instead connected to his private forensic practice. Still, questions about his departure remain, especially because he left his job just days after he appeared in court and encountered some pretty intense questioning about his background and expertise.
Mack testified that Clancy was clearly struggling with her mental health, but claimed that she should be held responsible.
Clancy, 36, is charged with killing her three children, Cora, 5, Dawson, 3, and 8-month-old Callan, in 2023. After killing her children, she tried to end her own life. She is paralyzed from the waist down because of the suicide attempt.
Clancy’s defense argues that she should not be held criminally responsible for her children’s deaths because she was experiencing postpartum psychosis. Meanwhile, Mack, who interviewed Clancy three years after this happened, said she was clearly struggling with her mental health, but that she did not show signs of psychosis. Instead, he claimed that she seemed to be struggling with major depressive disorder and could reasonably tell “right from wrong.”
“While depressed, her mental state was relatively stable,” he said, per The U.S. Sun.
His cross-examination got really heated.

Defense attorney Kevin Reddington questioned Mack’s knowledge of postpartum conditions. At one point, Mack was even asked about what “postpartum” actually means and he said the period lasts about four to six weeks after birth. Reddington pushed back on this understanding of the postpartum period and when postpartum mental health conditions might occur.
Additionally, Mack admitted that he did not evaluate Clancy for postpartum mental health conditions specifically, Boston 25 News reported.
At one point, Reddington even called him out for smiling during the interaction. “What are you smiling for?” Reddington questioned. “This is not funny, sir.”
Reddington also questioned Mack about his experience testifying about criminal responsibility. Mack said he had done this one or two times in the past, meaning that the Clancy trial was his third time, from what he could remember.
Not long after this happened, reports that Mack was no longer employed by the hospital emerged.
"Dr. Avram Mack is no longer employed by Nemours Children's Health, he resigned on Monday, August 24th," a hospital spokesperson tells me. Dr. Mack testified in Lindsay Clancy's trial on Friday, August 21 and Monday, August 24th.

It’s not clear what led to his departure. “Dr. Avram Mack is no longer employed by Nemours Children’s Health,” the hospital stated, per The New York Post. The hospital did not share any additional details at the time, as “employment decisions are confidential.”
Boston 25 News and WCVB reported that Mack resigned from his position at the children’s hospital. A spokesperson from Nemours Health told WCVB that Mack resigned on August 24, just two days after he testified. The reason for his resignation still hasn’t been confirmed.
