Psychologist Testifies in Lindsay Clancy Trial

Tuesday, August 25, 2026 · 5 sources

A psychologist hired by prosecutors testified about Lindsay Clancy's mental state. He said he believes Clancy was criminally responsible for killing her three children.

Kirk Heilbrun, a psychologist, told jurors that he does not believe Lindsay Clancy's claim that she hallucinated a voice telling her to kill her children. The children, who were 8 months, 2 years, and 5 years old, were killed by Clancy. Heilbrun said he instead believes Clancy took their lives so they wouldn't suffer after she planned to kill herself. Heilbrun's testimony was part of the ongoing trial.

The prosecution's case against Clancy relies on testimony from experts like Heilbrun. Clancy's defense team has argued that she was not criminally responsible due to her mental state at the time of the killings. Heilbrun's testimony contradicts this claim, stating that he believes Clancy was aware of her actions and made a conscious decision to harm her children.
