Stephen Joseph "The Rifleman" Flemmi (born June 9, 1934) is an Italian-American mobster and close associate of Winter Hill Gang boss James J. Bulger. Beginning in 1975, Flemmi was a top echelon informant for the Federal Bureau of Investigation (FBI). Despite delivering a great deal of intelligence about the inner workings of the Patriarca crime family, Flemmi's own criminal activities proved a public relations nightmare for the FBI. For this reason, he was prosecuted under the Racketeer Influenced and Corrupt Organizations Act (RICO) and sentenced to a long term of incarceration.
