The Criminal Investigation Division consists of various units each with personnel and equipment focused on a particular criminal activity: Crimes against persons (homicide, sexual assault, aggravated assaults, etc.) Property Crimes (auto theft, burglary, credit card abuse etc.) Narcotics and Special Crimes (vice, organized crime, intelligence and support functions such as surveillance and arrest teams).  The units receive information from various sources such as citizen complaints, outside agencies and confidential informants and work in concert with other jurisdictions such as the San Antonio Police Department, Probation and Parole, and the Department of Corrections.

The division is responsible for the collection, processing, storage and documentation of evidence to be used in court.  Investigators, officers and evidence technicians assigned to CID provide expert testimony.  CID clerks are responsible for the collection, processing and entering onto computer or permanent photographic storage of documents, reports and statements.  Fingerprints, photos and criminal histories are compiled of each person charged with a crime in Bexar County regardless of jurisdiction as well as warrants and probationers forwarded to Bexar County from other counties or states.

Records are maintained permanently to assist in local prosecutions and entered into computer databases such a those maintained by the FBI and Texas Department of Public Safety to aid other jurisdictions.  Records are initiated on convicted sex offenders and updated according to state statute.  All department records deemed to be in the public domain are copied and provided free to law enforcement agencies and the US military and to insurance companies, attorneys and the public for a fee.

Crime statistics and mapping technology are employed  to show patterns and increases in criminal activity for enforcement, planning and budgeting purposes.  Analytical data concerning auto accidents and speeding tickets, for example, is used by the Public Works Department and the Texas Department of Transportation in setting speed limits and designing roads.  Increasingly, businesses considering moves to San Antonio, such as Lowe's Home Improvement Stores, request crime statistics for their security and insurance cost planning.  These statistics are provided on a fee basis according to the cost of the compilation.  

Vehicles and other items of value seized from criminals or found abandoned are auctioned on a periodic basis as provided by statute.

In instances of death cases reported to the Bexar County Medical Examiner's office regardless of the jurisdiction within Bexar County in which there is no apparent next of kin, an investigator from CID is assigned to enter the persons domicile to research and make the appropriate notification.
