The Sacramento Valley Hi-Tech Crimes Task Force is part of the Centralized Investigations Division of the Sacramento Sheriff's Office. First organized in the mid-1990's, the Task Force is currently comprised of over 60 local, state, and federal law enforcement agencies. The Task Force consists of non-sworn personnel and full-time investigators from the Sacramento County Sheriff’s Office, California Highway Patrol, Sacramento Police Department, San Joaquin County Sheriff and Sacramento County Probation. In addition to numerous affiliate agencies throughout the Central Valley and Northern California work with the Task Force on a part time basis. Investigators are cross designated as United States Marshals and are Task Force Officers (TFOs) with the Federal Bureau of Investigation's Child Exploitation Task Force.

The Hi-Tech Crimes Task Force consists of three specialty teams: Identity Theft, Internet Crimes Against Children (ICAC) and Hi-Tech Crimes. Identity Theft Detectives conduct investigations of crimes which involve the theft and fraudulent use of a victim’s personal identifying information. Internet Crimes Against Children (ICAC) detectives work to protect children from sexual predators by investigating crimes involving child exploitation on the internet and pursue those involved with child pornography. Hi-Tech Crimes Detectives investigate other cyber related crimes such as the unauthorized access to computer systems.

In addition to the investigative teams, Task Force members also conduct forensic examinations of computers, cell phones and various other types of digital media seized in investigations of other crimes, such as homicide, upon request by detectives from other bureaus or affiliate agencies. Task Force members also assist outside agencies with training in the abovementioned areas.
