Overview

In 2016, the San Mateo County Sheriff's Office reorganized to support departmental growth. This change allowed for the Sheriff's Office to better address operational priorities and provide higher levels of service to our unincorporated areas and contract cities of Half Moon Bay, Millbrae, and San Carlos. A Sheriff's Captain fills the Chief of Police Services position in those contract cities.
While Investigations remains within the Operations Division, the area of responsibility was split into North County and South County Investigations. North County Investigations encompasses the unincorporated areas of northern San Mateo County; the San Mateo County coast from Devil's Slide south to the Santa Cruz County line, including the City of Half Moon Bay; the City of Millbrae; and the San Francisco International Airport. South County Investigations encompasses the unincorporated areas of southern San Mateo County including North Fair Oaks and the contract cities of Woodside, Portola Valley, and San Carlos.
By working collaboratively with our local, state, and federal partners, the Investigations Bureau maximizes the ability and effectiveness in combating criminal activity.

FY 2017-18 Mid-Year Story Behind Performance

Number of Cases Investigated

During the first half of FY 2017-18, the Investigations Bureau reviewed 4,742 cases. The recent increase in cases is due to a rise in property crime.  

Total Average Investigations Caseload per Investigator

The Investigations Bureau performed an average of 182 investigations per detective during the first of half of FY 2017-18. The Bureau added more detectives available to investigate cases, and therefore realized a reduction in workload per detective.

Annual Clearance Rate of Violent Crimes

In the first half of FY 2017-18, the annual clearance rate of violent crimes (criminal homicide, rape, robbery, assault) was 53% - exceeding the 50% target. The Sheriff's Office expects to continue surpassing this target for the rest of FY 2017-18 due to increased use of technology and criminal intelligence gathering. In addition, the concept of "Intelligence Led Policing" will aid in identifying criminal trends, occurrences of criminal events, and will assist in increasing the arrests of suspects involved in criminal activities.
