The Patrol Division is dedicated to providing the best service possible to the citizens of San Joaquin County. The Patrol Division is organized to provide emergency first response, investigation of reported crimes, provide specialized police services, and assist citizens in creating safe neighborhoods.

The Patrol Division has 138 deputies providing law enforcement services to the community. The deputies are deployed onto 10 patrol teams on two day off sequences (5 teams on duty each day). The county is divided into eight geographical areas or beats. These beat areas are staffed around the clock, providing emergency and non-emergency responses to calls for service within the unincorporated areas of the county.

Additionally, these same deputies act as Deputy Sheriff-Coroners, responding to unattended deaths in San Joaquin County (city and county). The deputies investigate the death, determine if foul play is suspected and coordinate the appropriate Investigation’s Divisional response if necessary and provide valuable investigation material to the pathologist who determines the medical cause of death.
