District Attorney Bureau of Investigation

Press Enter to show all options, press Tab go to next option

The District Attorney's investigative authority is the broadest of all local law enforcement agencies. The investigative functions of the District Attorney extend from the traditional support of prosecuting attorneys in hearings and trials to complex and specialized investigations not routinely handled by the detectives in traditional sheriff's and police agencies. The District Attorney's Bureau of Investigations' primary role is to provide prosecutorial support to its Deputy District Attorneys. In addition to these duties, the Bureau of Investigations oversees officer-involved shooting investigations, completes criminal investigations, assists in grand jury investigations, and conducts public integrity investigations.

The District Attorney has a staff of sworn peace officers and civilian personnel who perform a wide variety of tasks. The monumental task of providing trial support to "the people’s" prosecutors falls largely on the District Attorney’s Bureau of Investigation. Although all cases merit investigative support, staffing levels permit only a few individual cases (or in some cases particular programs augmented by grant funding) to receive extensive investigative attention based in large measure on the case’s size, potential impact or sensitivity. Investigations are conducted utilizing a wide range of techniques and resources ranging from traditional detective work to undercover operations and the utilization of specialized weapons and modern electronic equipment.

Mission Statement

The mission of the Bureau of Investigation is to support the prosecutorial efforts of the District Attorney's Office and to promote cooperation between the District Attorney's Office and all local, state and federal law enforcement agencies.
