General Investigations Unit
The General Investigations Unit is comprised of highly trained police officers and civilian employees who are committed to providing professional service to the community of Tracy by conducting thorough investigations to ensure a successful prosecution.
The unit works closely with other county, state, and federal organizations as well as the San Joaquin County District Attorney’s Office to obtain and secure criminal complaints and convictions.
The primary function of the General Investigations Unit is to provide follow-up to those cases which warrant investigation beyond what can be provided by patrol personnel. Oftentimes, these cases require additional technical skills and extensive follow-up.
Such crimes include homicides, robberies, gang-related crimes and intelligence, sex offenses, financial crimes, burglaries, and hi-tech crimes.
The General Investigations Unit comprises 1 sergeant, 10 detectives, 1 crime analyst, and 1 administrative assistant.
Special Investigations Unit
The Special Investigations Unit is responsible for investigating the use, sales, and transportation of illicit drugs, vice crimes, and human trafficking. Detectives work with the San Joaquin District Attorney’s Office in seeking successful prosecutions of those crimes. In addition, they provide expert courtroom testimony in the area of human trafficking and illegal drugs.
The Special Investigations Unit consists of four highly trained detectives and a supervisor who reports to the BOI Lieutenant.
The Crime Analyst provides varied analytical support relating to crime and criminal intelligence by researching, collecting, analyzing, and disseminating statistical information and reports to Department Command Staff to assist in making operational changes and decisions. Through the use of technology, they help to identify crime trends and work to establish patterns that may help to predict future criminal activity.
