John Francis McDermott

Police Officer John McDermott was accidentally shot and killed by another officer after being mistaken for a suspect.

Another officer had recently received several threats, and the appearance of strangers in the city required investigation. As Officer McDermott ran across a street towards where the suspects were another officer mistook him for a suspect and opened fire, striking him in the head and chest. He was taken to a local hospital where he died the following day.
