The Columbian reported that Brown – a 15 year veteran of the sheriff's office – was shot in his vehicle late Friday while conducting surveillance at a Vancouver apartment complex. He died later at a hospital, authorities said.

Vancouver Police said other units in the area were unable to reach the sheriff's detective on the radio at the time of the shooting. A resident reported hearing what sounded like gunshots and saw a man bleeding inside a vehicle.
