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 2017-18 Year-End Story Behind Performance

Number of Cases Investigated

During FY 2017-18, the Investigations Bureau reviewed 9,525 cases. This is an increase of over 2,000 additional cases from the prior fiscal that is attributed primarily to a rise in property crime.

Total Average Investigations Caseload per Investigator

The Investigations Bureau performed an average of 454 investigations per detective during FY 2017-18. The rise in total number of cases investigated by the Sheriff’s Office subsequently drove an increase in caseload per investigator.

Annual Clearance Rate of Violent Crimes

In FY 2017-18, the annual clearance rate of violent crimes (criminal homicide, rape, robbery, assault) was 59%, which is consistent with prior years. Looking forward, the Sheriff’s Office expects to push this number higher by increasing the use of technology and criminal intelligence gathering.

Technology that assisted in solving or deterring crimes include ALPRs, CellHawk, Facial Recognition, Smart Force and FirstTwo. In addition, the concept of “Intelligence Led Policing” will aid in identifying criminal trends and occurrences of criminal events which is expected to increase the number of arrests.
