(Miami-AP) -- A Boston man who's admitted to killing a Tulsa businessman 20 years ago has pleaded guilty to a murder in Florida.

John Martorano pleaded guilty to second-degree murder for the 1982 killing of former World Jai Alai president John Callahan.

Martorano has admitted to gunning down World Jai Alai owner Roger Wheeler outside a Tulsa country club in 1981.

Alleged mob leader James Bulger and assistant Stephen Flemmi are also charged in both murders. Martorano has agreed to testify against the two in exchange for reduced charges.

Authorities believe Wheeler was killed because he suspected Bulger's gang was skimming money from World Jai Alai. Callahan was allegedly killed because he could link the company to the gang.
