Bergen County Prosecutor


Hackensack, NJ

Welcome to
the Bergen County
Prosecutor`s Office

The Bergen County Prosecutor is the chief law enforcement officer for the County of Bergen. As a constitutional officer charged with the broad obligation "to use all reasonable and lawful diligence for the detection, arrest, indictment and conviction of offenders against the laws," the Prosecutor has wide-ranging authority over the law enforcement community in the county. With that authority come tremendous responsibilities and obligations, both to the law enforcement community itself and to all the citizens of Bergen county.

Our Mission:

The mission of the Bergen County Prosecutor`s Office is to commit its resources, in partnership with the law enforcement community and citizens of Bergen County, to promote a safe and secure environment for the residents of Bergen County while maintaining the highest law enforcement standards. The members of this office will effectively and efficiently investigate and prosecute criminal offenders, fairly, impartially and justly. We will ensure and respect the rights of individual victims of crime. In addition to conducting its own proactive investigations, the Bergen County Prosecutor`s Office maintains specialized squads that are available to assist the municipal departments in the investigation of crimes calling for increased personnel, specialized equipment, technical know-how or highly specialized training. Such crimes include arson, homicide, sex crimes, drug trafficking, traditional organized crime, domestic violence, insurance fraud and most recently, computer crimes. These squads give each municipality the ability to bring additional resources to bear when presented with particularly challenging cases or particularly dangerous offenders.
