Psychologist challenges Lindsay Clancy psychosis defense in Massachusetts murder trial

A psychologist testifying for the prosecution in the Lindsay Clancy murder trial dismissed her claim of acute psychosis, prompting a mistrial request from her defense that was denied. Clancy is accused of killing her three children in Massachusetts in January 2023. Prosecution witness Kirk Heilbrun testified he did not believe Clancy heard a voice telling her to kill her children, calling her described hallucination pattern "very unusual." He concluded she killed them because she wanted to die but did not want to leave them behind, referencing her Catholic faith. The defense argued the religion mention was intentional misconduct, but the judge instructed the jury to ignore it. Clancy has pleaded not guilty, with her team arguing she suffered from postpartum psychosis and should not be held criminally responsible.
