Upon taking office in 2022, District Attorney Tierney immediately formed the first Violent Criminal Enterprises Bureau to combat organized crime and gang violence in Suffolk County, and re-established the office’s Homicide Bureau as a distinct bureau.
Additionally, during his first year in office, District Attorney Tierney formed two specialized prosecution units: the Biological, Environmental, and Animal Safety Team (BEAST), and the Hate Crimes, Elder Abuse, Anti-Bias/Immigrant Affairs and Human-Trafficking Unit (HEAT).
District Attorney Tierney also recognizes that robust community outreach is vital to a modern prosecutor’s office, and as such, formed a Community Outreach Bureau which hosts job fairs, coordinates educational programs and summits, and much more.
