CHRISTOPHER L. DEWEY

Deputy Sheriff Chris Dewey succumbed to gunshot wounds sustained 18 months earlier after responding to reports of a drunk driver and shots fired in the city of Mahnomen.

On February 18, 2009, Deputy Dewey responded to the call in the town of Mahnomen. When he arrived, he encountered two suspects, and a physical confrontation ensued. He was shot in the head and abdomen by one of the men. When backup units arrived, they found Deputy Dewey and transported him to the hospital.

A search for the suspect led to a nine-hour standoff at a mobile home that was near the scene of the incident. The suspect eventually surrendered to police.

Deputy Dewey underwent a series of operations and required rehabilitative care following the initial shooting. In July, he was moved into hospice care where he died from his wounds on August 9, 2010.

The suspect was found guilty of first-degree murder on September 1, 2011, and sentenced to life without the possibility of parole. His accomplice was sentenced to two years in prison for failing to render aid.

Chris' badge number, 909, was retired by retired Sheriff Doug Krier, and all Mahnomen County squad cars have Chris' badge number on them in his memory.
