Luigi Mangione will assert psychiatric defense in murder case in UnitedHealthcare CEO’s killing

Luigi Mangione will use a psychiatric defense in his state murder trial for killing UnitedHealthcare CEO Brian Thompson, admitting the act but citing emotional disturbance. A judge will unseal records related to the defense, which could lead to a manslaughter conviction instead of murder. Mangione faces both state and federal trials, with evidence including a 3D-printed pistol and a notebook linking him to the crime.
