Units and Teams
Child Abuse and Sexual Assault Unit
The CASA unit is responsible for child abuse, sexual assault, elder physical abuse, missing children, and the monitoring of sex registrants. Investigators assigned to this unit receive specialized training in sexual assault, child abuse, and missing persons investigations.
The Persons Unit’s responsibility is to investigate crimes against persons such as robbery, kidnapping, murder, assaults, rape, juvenile crime, and any other crime against persons. The Persons Unit has investigators who have specialized training in the investigation of homicide cases and also on location for gathering and processing evidence at crime scenes.
Property Crimes Unit
The Property unit is made up of investigators who investigate crimes against property such as burglary, documents, theft, embezzlement, bad checks, and any other crimes against property. The unit has specially trained investigators. The San Joaquin County Sheriff’s Office investigates all property crimes that occur in the unincorporated areas of San Joaquin County.
If you are a victim of burglary or a property-related crime, investigative services attempt to respond with patrol. The documentation process may include photographs, a check for latent prints, and a written narrative regarding the condition of the crime scene. While this is an important process, there are other factors even more important in the probability of your case being solved. It has been our experience that most cases are solved through the tracking of property (serial numbers), word of mouth, and citizen observations.
Technical Services Unit
San Joaquin County Sheriff’s Office provides fingerprint registration via liveScan technology. The LiveScan operator will enter information from the submission form and captu4re the fingerprint images. The captured information is immediately transmitted to the Department Of Justice (DOJ).
