While Winter Hill Gang members were alleged to have been involved with most typical organized crime-related activities, they are perhaps best known for fixing horse races in the northeastern United States. Twenty-one members and associates, including Howie Winter, Joe McDonald, Johnny Martorano, and Sal Sperlinga were indicted by federal prosecutors in 1979. The gang was then taken over by James J. "Whitey" Bulger and hitman Stephen Flemmi and was headquartered in South Boston. During the 1980s, Bulger's key criminal associates were Kevin Weeks and Patrick Nee.
