On December 17, 1935, Officer Charles H. Nissen was killed in a traffic collision while riding his departmental motorcycle.
Officer Nissen was pursuing a traffic violator when a vehicle ahead of him slowed for a turn. Nissen applied his brakes to reduce his speed, but his motorcycle struck the rear of the vehicle. The patrolman was thrown to the pavement and died at the scene.
Officer Nissen was assigned to the Contra Costa Area office.
