The Suffolk County District Attorney’s Office is committed to eradicating violent street gangs from Suffolk County.

In January 2018, District Attorney Sini announced the formation of a Gang Unit within the Enhanced Prosecution Bureau to focus exclusively on investigating and prosecuting crimes committed by gang members, including members of MS-13. The Unit comprises eight Assistant District Attorneys and six Detective Investigators. It works closely with a multitude of law enforcement agencies, including local, state and federal agencies.

The Gang Unit is responsible for the prosecution of all gang-related crimes, as well as all prosecutions in which the defendant is a known gang member. By streamlining gang prosecutions under the purview of a single Unit, those prosecutors are able to become experts on gang prosecutions, the gangs operating in Suffolk County, the way gangs operate generally, and on specific identified gang members here in Suffolk County.

The Assistant District Attorneys and Detective Investigators in the Gang Unit receive extensive training both internally and externally by gang experts so they are continuously informed of the latest gang-related intelligence and are on the cutting edge of gang prosecutions. The Gang Unit also hosts bi-weekly meetings with all local, state and federal law enforcement agency involved in the arrest, prosecution, imprisonment and post-release supervision of gang members in Suffolk County to share intelligence and coordinate enforcement efforts.
