March 21, 2001 (MIAMI) – A Boston mob hitman who admits to killing at least 11 people, has pleaded guilty to killing the former president of World Jai Alai in 1982 in order to cover his tracks in another homicide.
Johnny Martorano’s plea agreement with federal prosecutors gives him a 15-year prison term in return for his testimony against James “Whitey” Bulger and Stephen “the Rifleman” Flemmi.
John Callahan’s body was found in the trunk of his Cadillac at Miami International Airport. During a hearing Tuesday, Martorano said that Callahan had given helpful leads the year before when the Bulger gang killed World Jai Alai owner Roger Wheeler, including telling the assassins where Wheeler played golf.
Wheeler was killed in the parking lot at a Tulsa, Okla., country club, allegedly because he had learned that the Bulger gang was skimming jai alai profits.
Bulger, who has been a fugitive for several years, and Flemmi are charged with racketeering, conspiracy and murder. One FBI agent has been charged and others are under investigation for allegedly protecting members of the gang who served as government informants.
