investigation · Criminal Investigation Division

The Criminal Investigation Division (CID) was formed in 1982 as part of the Investigative Services Bureau (ISB). CID's main function is to provide follow-up investigative assistance on cases that go beyond the crime scene. This allows line personnel to return to regular duties sooner while enhancing the quality of the investigations. Sixty-eight trained detectives are divided among eight district offices throughout the state.

The division consists of three major sections comprised of detectives assigned to Felony Collision and Criminal Investigation Units, Auto Theft Units, and Special Investigations.  The Vehicle Identification Number (VIN) inspection program is also a vital part of CID.

CID Sections

Felony Collision / Recon - is comprised of eight Criminal Investigation Units (CIUs) located throughout the state. The CIU detectives are responsible for investigating felony collisions that occur on state routes; as well as a wide range of crimes resulting from our troopers' traffic stops. On request, CIU detectives provide assistance to other agencies with investigations of homicides, shootings and other violent crimes.

Auto Theft Section - is comprised of three regional units, located in Tacoma, Seattle, and Spokane. The goal of the Auto Theft Section is to reduce the incidence of vehicle and major component part thefts and related crime. Our partnership with the National Insurance Crime Bureau has enabled us to become better equipped to combat auto theft and related crimes.

Special Investigations - is comprised of a General Investigation Unit (GIU), which conducts investigations of crimes occurring on the capitol campus or at other state agencies, and the following units which are partnered with other Washington State agencies: Major Accident Investigation Team (MAIT), the Identity Theft Unit (ITU); and two Special Investigation Units (SIU) - the Office of the Insurance Commissioner (OIC) SIU and the Department of Social and Health Services (DSHS) SIU.

MAIT is charged with investigating catastrophic collisions occurring within the jurisdiction of the WSP, and has a partnership with the Department of Transportation. Our ITU is housed in Olympia and works with the Department of Licensing (DOL) staff to investigate cases of identity theft and fraud.

The DSHS SIU conducts criminal and administrative investigations involving DSHS employees statewide. The OIC SIU is housed with the Office of the Insurance Commissioner in Olympia, working with their SIU to investigate insurance fraud.

VIN Program - a vehicle is physically examined at a Washington State Patrol VIN inspection station to ensure it matches the documentation presented to the inspector and the Department of Licensing during a title transaction. The VIN inspection is not for determining the safety of a vehicle or its components.

A physical inspection is also conducted on vehicles that have been rebuilt after being destroyed or declared a total loss by an insurance company. The VIN inspectors will also perform physical inspections as required on vehicles reported stolen, homemade vehicles, or other vehicles without a proper VIN, when there is a VIN discrepancy, when there is a record dispute, when ownership is in doubt, or other special cases.
