Key facts
- Lindsay Clancy has bipolar disorder, a forensic psychologist testified.
A forensic psychologist testified Monday that Lindsay Clancy has bipolar disorder and was experiencing anxiety, depression, insomnia, and suicidal thoughts in the weeks before she killed her three children. This contradicts a previous expert's testimony.
The testimony of expert witnesses regarding Lindsay Clancy's mental state is central to determining her criminal responsibility for the deaths of her three children, potentially impacting the trial's outcome and sentencing.
A forensic psychologist testified Monday that Lindsay Clancy has bipolar disorder and was experiencing anxiety, depression, insomnia, and suicidal thoughts in the weeks leading up to the January 2023 killings of her three young children. Kirk Heilbrun, who examined Clancy for three days this year, presented a differing conclusion from a forensic psychiatrist who testified Friday that Clancy did not have bipolar disorder or psychosis.
Both Heilbrun and Dr. Avram Mack testified as rebuttal witnesses for the prosecution in the murder trial, which centers on Clancy's mental state at the time of the killings. Closing arguments are anticipated later this week.
Clancy's attorney, Kevin Reddington, does not dispute that his client killed the children but argues she should not be held criminally responsible due to postpartum psychosis, a rare mental illness associated with childbirth stress, sleep deprivation, and hormonal changes. Reddington also stated Clancy had bipolar disorder, and that prescribed antidepressants worsened her condition.
Prosecutors, however, maintain that the former labor and delivery nurse planned the killings. They allege she orchestrated her husband's departure to pick up medicine for a child and dinner for the family.
Heilbrun stated he found it difficult to diagnose bipolar 2 disorder due to the variety of diagnoses and symptoms in Clancy's records, noting a lack of clear manic episodes. He described periods where Clancy felt good after childbirth as feeling "really good" rather than manic. Heilbrun also referenced earlier testimony regarding Clancy's sleep issues, adverse reactions to medications, anxiety about returning to work, and intrusive thoughts. He noted that during a two-week hospital stay prior to the killings, Clancy did not report hallucinations or suicidal thoughts, with insomnia being her primary concern.
Clancy, 36, has pleaded not guilty to murder charges in the deaths of her children, Callan, Dawson, and Cora, who were aged 8 months to 5 years old. The prosecution and defense have presented conflicting expert testimony regarding Clancy's mental state, specifically postpartum psychosis.
