And notorious South Boston mobster James “Whitey” Bulger was beaten to death by fellow prisoners Tuesday, a day after he was transferred to a West Virginia prison. Whitey Bulger was convicted in 2013 of a host of crimes, including 11 murders, and sentenced to life in prison. Bulger served as an FBI informant, and the agency helped enable his reign of terror in the 1970s and 1980s. He fled from public view in the mid-1990s following a tip from an FBI agent about an upcoming indictment. In 2011, authorities found Bulger in Santa Monica, California, where he had more than $800,000 in cash stashed in the walls of his apartment. Whitey Bulger was the brother of Billy Bulger, a powerful Massachusetts Democrat who was the longest-serving president of the state Senate.
