Overview

In 2016, while the Investigations Bureau remained within the Operations Division, the area of responsibility was split into North County and South County Investigations. North County Investigations encompassed 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 encompassed the unincorporated areas of southern San Mateo County including North Fair Oaks and the contract cities of Woodside, Portola Valley, and San Carlos.
In June of 2017, the San Mateo County Sheriff’s Office Investigations Bureau reorganized and returned to a structure where teams were divided between persons crimes and property crimes. The detectives assigned to the North County Investigations Unit returned to Redwood City and formed the Major Crimes Unit and the General Crimes Unit.
By working collaboratively with our local, state, and federal partners, the Investigations Bureau maximizes the ability and effectiveness in combating criminal activity.

FY 2018-19 Mid-Year Story Behind Performance

Number of Cases Investigated

During the first half of FY 2018-19, the Investigations Bureau reviewed 2,916 cases. This slight decrease can be attributed to a shift in how the Sheriff’s Office operates. In more cases, patrol deputies are being tasked with investigating their own cases as far as they are able before it is handed over to the Investigations Bureau.

Total Average Investigations Caseload per Investigator

The Investigations Bureau performed an average of 194 investigations per detective so far in FY 2018-19. The decrease in total number of cases reviewed by the Sheriff’s Office has translated into a more manageable caseload per investigator.

Annual Clearance Rate of Violent Crimes

So far in FY 2018-19, the annual clearance rate of violent crimes (criminal homicide, rape, robbery, assault) is 60% - exceeding the 50% target. This data point is 7% higher than the first half of FY 2017-18. The increased use of technology and the concept of “Intelligence Led Policing” have helped to increase arrests and “clear” a higher number of violent crimes.
