Almost two decades after a corrupt FBI agent helped him avoid capture, reputed crime boss James “Whitey” Bulger is facing a trial this week that may shed new light on a shameful period for the FBI, reports Bloomberg News. Bulger, 83, is accused of 19 murders and widespread racketeering while he led an Irish-American organized crime gang in South Boston from the 1970s to the early 1990s. Prosecutors say Bulger was an FBI informant during most of that time, and at least three agents were corrupted by his alleged schemes. (Bulger today sought a delay in the trial in a dispute over a key witness.) Bulger was captured in 2011 after 16 years on the run, and may spend the rest of his life in prison if he’s found guilty. Opening statements are scheduled for Monday. Bulger, who grew up in the predominantly Irish-Catholic housing projects of South Boston, became involved in serious crimes at a young age, including rape, and spent three years in the Alcatraz federal prison for bank robbery before rising to dominate much of Boston’s criminal underworld. His list of alleged victims includes gangsters who crossed him and two young women who were missing for years before their bodies were unearthed in secret mob graves.
