Psychologist testifies Lindsay Clancy had bipolar disorder before killing children

A forensic psychologist testified Monday that Lindsay Clancy has bipolar disorder and was experiencing anxiety, depression, insomnia and suicidal thoughts before killing her three children, contradicting a prosecution expert who found no such conditions. Kirk Heilbrun, who examined Clancy over three days this year, said he struggled to reach a bipolar 2 diagnosis because he found no clear manic episode, echoing testimony about her sleep struggles and medication reactions. His testimony followed Dr. Avram Mack, who said Friday Clancy had a major depressive episode but no evidence of mania or psychosis. Clancy, 36, has pleaded not guilty to murder charges in the January 2023 deaths of her children, aged 8 months to 5 years. Her defense argues postpartum psychosis makes her not criminally responsible, while prosecutors say she planned the killings. Closing arguments are expected later this week.
