Bureau Of Investigation

The Bureau of Investigation is the peace officer unit of the District Attorney's Office. The Bureau currently has 90 investigators who, unlike deputy district attorneys, are peace officers and have the same powers as police officers.
The Bureau consists of a Criminal Division and a Public Assistance Fraud Division. The Bureau also has a process serving unit to serve legal documents for the District Attorney's Office.
The District Attorney Bureau of Investigation has statutory or customary original investigative jurisdiction in several subject matters, such as child stealing, conflict of interest, police misconduct, and many white-collar crimes. Investigators also ensure cases are prepared for prosecution after charges have been filed as investigation and the gathering of evidence relating to criminal offenses is a responsibility that is inseparable from the district attorney's prosecutorial function. The Bureau also participates in the FBI's regional Joint Terrorism Task Force and several other regional task forces with local, state and federal law enforcement agencies.
