Incident
Lieutenant Robert Dorn was shot and killed by a stranded motorist he had stopped to help on 91st Avenue just north of Glendale Avenue. The man had been visited recently by deputies inquiring about his delinquent taxes. Believing that he was about to lose his trailer home, the man jumped out of his truck and began firing without warning, killing Lieutenant Dorn. Despite being mortally wounded, Lieutenant Dorn was able to return and wounded the man. The subject was found not guilty by reason of insanity and committed to a mental institution. He was later released. Lieutenant Dorn had served with the Maricopa County Sheriff's Office for 10 years.
Survivors
He was survived by his wife, three children, and brother.
