Lindsay Clancy trial judge denies mistrial request, but reprimands prosecution over witness testimony about religion

TL;DR

  • A mistrial was requested when witness Dr. Kirk Heilbrun spoke about Catholic beliefs and suicide, which the defense argued was irrelevant and inflammatory.
  • Judge William Sullivan denied the mistrial but reprimanded the prosecution, stating the testimony was immaterial and irrelevant.
  • This is the second instance of religion being brought up during the trial, with a previous question being struck from the record.
  • Dr. Heilbrun, a forensic psychologist, testified about Clancy's mental health history, including anxiety and depression exacerbated by Zoloft.
  • Clancy faces first-degree murder charges for the deaths of her three children, with the prosecution arguing premeditation and the defense claiming postpartum psychosis.
