James 'Whitey' Bulger, leader of the Winter Hill Gang in South Boston, was recruited as an FBI Top Echelon Informant by Special Agent John Connolly in September 1975. Over the following two decades Bulger and associate Stephen Flemmi used their FBI-protected status to commit 19 or more murders — including killings of potential witnesses and rival informants — while Connolly tipped Bulger off to investigations and rival informants. Connolly was convicted in 2002 (racketeering) and 2008 (second-degree murder, Florida). Bulger fled in December 1994 after a tip-off, was captured in Santa Monica in June 2011, convicted in August 2013, and was killed in a West Virginia federal prison in October 2018.
