The Collision Investigation Unit or CIU is made up of officers who have specialized collision investigation training. The CIU officers investigate fatality collisions, or those collisions that result in serious damage or injury.
In some cases, a CIU investigation will result in criminal charges such as Felony Eluding, Felony Impaired Driving, or Vehicular Assault or Vehicular Homicide. Additionally, these investigations may include vehicles, bicycles, pedestrians, trains, and aircraft.
Our CIU also assists other police agencies throughout Snohomish County through a mutual aid request.
