Dr. Avram Mack, a psychiatrist who testified for the prosecution in the Lindsay Clancy murder trial, is no longer employed by Nemours Children’s Health, the organization confirmed Friday. Mack resigned from his position on Monday, the same day he appeared on the witness stand.
Mack, a witness for the prosecution, stated that Clancy was in a "serious psychiatric state and she was suffering" on January 24, 2023, the day she is accused of strangling her three young children in their Duxbury, Massachusetts home. However, Mack concluded that Clancy should be held criminally responsible for their deaths.
During the trial, Clancy's attorney, Kevin Reddington, questioned Mack extensively about whether the former labor and delivery nurse was experiencing psychosis at the time of the incident. Mack testified that he found no evidence of "psychotic features" in her medical records. The psychiatrist, who evaluated Clancy in April 2026, engaged in a contentious exchange with Reddington, who accused Mack of smirking on the stand. "What are you smiling for?" Reddington reportedly asked. "This is not funny, sir."
The development comes as the jury concluded its second day of deliberations without reaching a verdict. Clancy, 36, faces a potential sentence of life in prison without parole if convicted of murder. An alternative verdict could be not guilty by reason of insanity, which would lead to her placement in a psychiatric facility until she is no longer deemed a threat.
Jurors are scheduled to resume deliberations on Monday in Plymouth, Massachusetts.
