Bulger was the boss of Somerville's Winter Hill Gang, and controlled organized crime syndicates throughout metro Boston and New England in the 1970s and '80s. At some point during the 1970s, it is believed that the FBI successfully turned Bulger into a federal informant, with information that he provided being used to investigate and convict other members of crime organizations. It's still unclear if that played any role in his death today.
