The Criminal Investigations Bureau is responsible for the investigative follow up of all incident reports generated by Patrol, to ensure every report written receives the proper case closure. The Detectives in the Criminal Investigation Division work diligently to solve crimes reported to Patrol.
The Criminal Investigations Bureau is allotted for one Detective Sergeant and eight Detectives. Five of the Detectives are generalist investigators, who may investigate both Crimes against Property and Crimes against Persons.
Detectives assigned to Crimes against Property investigate such acts as burglary, auto theft, financial transaction fraud, and identity theft.
Detectives assigned to the Crimes against Persons unit investigate armed robberies, murder, aggravated assault, rape, family violence and other crimes against the person.
The remaining three Detectives are assigned to the following Task Forces: San Mateo County Narcotics Task Force, San Mateo County Vehicle Theft Task Force, and the Drug Enforcement Agency (DEA) Task Force.
All Detectives hold the parallel rank of Corporal when assigned to Patrol.
