Lindsay Clancy's mental illness led to tragedy, psychologist says

August 20, 2026 - 09:05

A forensic psychologist called by the defense in the Lindsay Clancy case testified on Tuesday that the mother of three was so severely impaired by mental illness that she did not grasp the wrongfulness of her actions when she killed her children. The testimony is a key part of the defense's effort to build a case for a verdict of not guilty by reason of insanity.

Dr. Jennifer Brown, a clinical and forensic psychologist, told the court that Clancy was suffering from a major depressive disorder with psychotic features at the time of the killings in January 2023. Brown said that Clancy's condition, compounded by postpartum depression and anxiety, had reached a level where her perception of reality was fundamentally distorted. According to the psychologist, Clancy believed she was saving her children from a fate worse than death, a delusion that removed her ability to make a rational moral judgment.

The prosecution has argued that Clancy's actions were deliberate and that she was aware of what she was doing, pointing to the fact that she allegedly researched methods and sent text messages that showed some level of planning. However, Brown countered that those behaviors were not evidence of rationality but rather of a desperate, disorganized mind trying to impose a twisted logic on an unbearable situation. The trial is expected to continue with cross-examination of the psychologist later this week.
