Robert L. Dorn

Lieutenant Dorn was shot and killed by a stranded motorist he had stopped to help. The suspect 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, he was able to return and wounded the suspect.

The suspect was found not guilty by reason of insanity and committed to a mental institution. He was later later released.

Lieutenant Dorn had served with the agency for 10 years. He was survived by his wife, three children, and brother.

Robert Dorn was my next door neighbor when I was a teenager living in Glendale, Arizona. Though I did not know him well, he was an influence on me to eventually make policing my career. I spent 30 years with Phoenix PD and retired as a sergeant in 2001. Coincidentally, the neighbor to the opposite side of our residence was Glendale PD Sergeant Frank Chambers.
