Park ranger James Kilroy kills wife, pleads not guilty by reason of insanity due to acute and transient psychosis.

A park ranger, James Kilroy, likely suffered an acute and transient psychotic disorder when he killed his wife, according to a murder trial. Kilroy has pleaded not guilty by reason of insanity. Consultant Psychiatrist Dr Lisa Wootton testified that while cannabis-induced psychosis was a possibility, she prefers the diagnosis of acute and transient psychosis, as its symptoms align better with Kilroy's fluctuating mental state during the incident.
