Community Prosecution is a pro-active, solutions based approach to justice where prosecutors are both a representative of and a leader in a community.  Community prosecutors reach out to community groups, schools, faith-based groups and other community organizations to identify concerns and prioritize strategies for addressing them, working with local and state police and other government agencies to share intelligence, strategize, and support. 

District Court is the gateway to the justice system. It is where the vast majority of criminal cases in Massachusetts are handled.  The district courts have jurisdiction over all misdemeanors, including drug offenses, weapons offenses and motor vehicle offenses. 

The Juvenile Justice Unit works to reduce youth violence and crime using a coordinated community approach which includes early intervention and prevention.  In addition, when appropriate, the unit handles those serious juvenile cases who are indicted as Youthful Offenders, thus making them open to full adult criminal prosecution.

Superior Court is the court in which major felonies such as murder, robbery, drug trafficking and serious crimes of violence and abuse are prosecuted. These types of cases must first be presented to a Grand Jury, which issues indictments charging defendants with these serious crimes.
