A forensic psychologist testifying for the prosecution stated that Lindsay Clancy has bipolar disorder and was experiencing mental health issues prior to the killings of her three children. Kirk Heilbrun, who examined Clancy, told the court he questioned her claims of hearing a hallucinated voice commanding her to commit the act, suggesting she took their lives so they would not "suffer" after she killed herself. Heilbrun's testimony contrasts with defense experts who concluded Clancy was psychotic and not in control of her actions due to postpartum psychosis. Prosecutors contend Clancy planned the murders and deceived her husband. Clancy has pleaded not guilty to murder charges. Closing arguments are expected this week.
