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.

The presentation educates students on the dangers of experimentation with prescription medication, specifically Opiates, and how it corresponds directly with the increase in Heroin use by young people. Presenters will provide first-hand accounts and examples of Heroin-related arrests, overdoses, and deaths throughout Bergen County. Students will leave with a practical, real-world education on the chilling effects Heroin can have on their lives and the importance of good decision-making.


Presentations provided by the Bergen County Prosecutor`s Cyber Crimes Task Force can be requested by any school system within the county. Please review this page before following the below-listed links to the Cyber Crimes Presentation Request Forms.

Note that there has been an overwhelming demand on the Cyber Crimes Unit for these and other presentations. As such, preference will be given (where noted) to those organizations that conform to the suggested guidelines. The online forms will request contact information from any organization interested in hosting a presentation. The request is then forwarded to members of the Unit for scheduling based on availability of Cyber Crimes Task Force personnel. You may use the notes field at the bottom of the request form to describe any special issues or concerns that you may have for your presentation; it can also be used to describe your student body or school system if we should know something in particular about your school community.

(Approximately 50 minutes - 1 hour)

Requests for this presentation should be limited to students of middle school age. The presentation that the Cyber Crimes Unit delivers is age-appropriate for 6th grade and is most effectively delivered in that arena. Requests for this presentation should be limited to 6th grade only, but may incorporate 7th and 8th grade students who did not attend this presentation as 6th graders, or did not otherwise attend this presentation elsewhere.

The Internet Safety presentation for Students from the Bergen County Cyber Crimes Task Force typically lasts about 1 hour. This program is a dynamic, entertaining, and informative 360-degree discussion about Internet Safety (general), information control, social networking mistakes, sexting, and cyberbullying. Experience has taught us that getting the students into the auditorium, seated and ready can often delay the start of the presentation. A few minutes should be allowed for this and/or questions by students at the end (if applicable), which could prolong the total length of the presentation. Also, if a school administrator plans to make opening/closing remarks, please calculate this into the start/end times accordingly. Presentation talk-time with full PowerPoint, entertaining video clips, etc. will consist of probably 50 solid minutes. Feedback has consistently indicated that the 50 minutes are well spent, and contain useful educational, entertaining and interesting content.

(Approximately 45 minutes - can be modified based on time constraints)

This presentation often coincides with prom season and graduation season for High School Juniors and Seniors. It is typically presented to the 11th and/or 12th grade(s), but schools may include students as young as 9th grade if they so choose. The presentation is not appropriate for students 8th grade or younger. The presentation educates students on the dangers of drinking and driving, hosting parties where alcohol is served/present, texting while driving, and the consequences following collisions resulting from DWI, reckless driving, cell phone use, and more. Presenters incorporate first-hand experience in cases involving teen drunk driving, distracted driving and fatal accidents. The host agency/school should choose between two themes for the presentation; DWI or Cell Phone Use Behind the Wheel. Depending on the theme of the presentation, two videos are available which may be incorporated. Both videos are approximately 22 minutes long, and will be followed by a lecture/Q&A session designed to fit within the allotted time frame. Regardless of the host’s choice of the primary theme, both topics will be touched upon during the lecture. The DWI video was produced by the Bergen County Prosecutor’s Office, and depicts a fictional yet typical case of teen drunk driving resulting in a fatal accident. The cell phone themed video was produced collaboratively by the top four major cellular telephone companies as a PSA, and it tells the stories of drivers and victims involved in serious motor vehicle accidents caused by distracted drivers
