Bureau Of Investigation


The Bureau of Investigation includes 86 sworn peace officers that have the same statutory authority as police officers. These include the Chief Investigator, Assistant Chief Investigator, and six Supervising Criminal Investigators, who supervise various units within the Bureau. Additionally, the Bureau has a number of civilian staff that provide process service and support functions for the District Attorney’s Office.

The mission of the Bureau of Investigation is to provide quality and timely investigation and support for the prosecutorial functions of the District Attorney’s Office. Generally, the Bureau conducts follow-up investigations on cases submitted to the District Attorney by local law enforcement agencies and other county departments, such as serious felony cases, homicides, sexual assaults, robberies, gang cases, narcotics, arson, and other major cases. District Attorney Investigators also assist other law enforcement agencies where assistance, staffing, or specific expertise may be desired.

The Bureau also assumes original jurisdiction and is the primary investigative agency in a wide variety of economic crime cases including real estate fraud, major fraud, consumer fraud, elder financial fraud, worker’s compensation fraud, health/long-term disability fraud and auto fraud.  Additionally, the Bureau is the primary investigative agency for parental child abductions, Election Code violations, crimes committed by public officials, Fair Political Practices Act violations, Corporation Code violations, environmental health violations, and high-tech crime.
