Prosecution rebuttal: not psychosis, and a mistrial motion denied

Lindsay Clancy Trial · The full record

The Commonwealth's rebuttal continued. Dr. Avram Mack maintained Clancy had a major depressive disorder rather than psychosis and that psychosis alone would not necessarily prevent someone from knowing right from wrong. Dr. Kirk Heilbrun, a forensic psychologist, told jurors the killings were part of a suicide attempt — that Clancy wanted her children "to be with her so they wouldn't suffer" — called the act out of character, and pointed to inconsistencies in her accounts of hearing a voice. Defense attorney Kevin Reddington moved for a mistrial over Heilbrun's remark that the Catholic Church treats murder as a mortal sin; Judge William Sullivan denied the motion and instructed jurors to disregard the remark as irrelevant.
