The San Bernardino County District Attorney’s Bureau of Investigation is committed to providing quality and responsive investigative services to prosecutors, our community, and all those serving throughout the criminal justice system.

The bureau is composed of sworn peace officers, investigative technicians, trial prep coordinators, witness coordinators and other professional staff. These staff members are assigned to five district attorney facilities providing services that cover over 20,000 square miles.

The average district attorney investigator hired by the San Bernardino County District Attorney’s Office has fifteen years of law enforcement experience. Typically our investigators have served with a police or sheriff’s department a minimum of three years as a detective before transitioning to a position as a district attorney investigator.
