James Callahan was tied to the Winter Hill Gang and became a target after the May 1981 daylight murder of Tulsa businessman Roger Wheeler, an FBI inquiry that focused attention on several gang associates. Fearing Callahan might break under federal questioning and identify them in the Wheeler case, gang leaders James Whitey Bulger and Stephen Flemmi ordered his killing after receiving a tip that the FBI was seeking him.

On July 31, 1982, enforcer John Martorano carried out the killing. Callahan’s body was later found in the trunk of his Cadillac, abandoned in a parking lot at Miami International Airport. Subsequent developments linked the murder to corruption within the FBI when former agent John Connolly was accused of informing the gang that Callahan was wanted for questioning.

Who knew James Callahan or has information about his last movements before July 31, 1982?
