Some key players may be dead.
Still, the website, Gangster Report, lists a host of live reputed mobsters -- including offspring of the dead ones -- who might be able to shed light on the 1975 disappearance of ex-Teamster boss James R. Hoffa.
Two of the people on the list include Joseph (Joey Jack) Giacalone, son of the late Detroit mafia street boss Anthony (Tony Jack) Giacalone and Jack (Jackie the Kid) Giacalone, son of the late mobster Billy Giacalone, alleged to be the current Detroit mob Don. The elder Giacalone fathers were brothers.
Of Jack Giacalone, the website writes:
Jack (Jackie the Kid) Giacalone – Alleged to be the current Detroit mob Don and the son of Billy Giacalone, Jackie the Kid was only 25 at the time of the Hoffa hit, but was very close with his dad and uncle and was being groomed for the boss’ chair since the early 1980s, so it wouldn’t be hard to believe that he was given the “inside scoop.”
Another person who made the list: Anthony (Chicago Tony) La Piana.
The website writes of La Piana:
Alleged to be the current Detroit mob underboss and a protégé and nephew via marriage to recently-deceased Michigan Don Giacomo (Black Jack) Tocco, Chicago Tony has been the Midwest mafia’s labor-union representative since the early 1980s and the assassination of his predecessor Allen Dorfman, according to federal documents related to former Teamsters president and FBI informant Jackie Presser. Investigators think La Piana, 70, may have been filled in on details of the Hoffa hit by his mentors Jack Tocco and Tocco’s one-time underboss Vincent (Little Vince) Meli , his father-in-law who died of cancer in 2008 and was a longtime liaison between Hoffa, the organized labor movement and the mob.
The site also names Tommy Andretta, a "retired New Jersey wiseguy who was a young mob soldier under the tutelage of Genovese crime family caporegime Anthony (Tony Pro) Provenzano and has been implicated in the high-profile homicide since the start of the investigation 40 years ago. Andretta, 75, currently lives in Las Vegas, but back on July 30, 1975, he’s believed by authorities to have been one of Provenzano’s representatives on the Hoffa hit, according to FBI files, most likely used for “clean up” purposes."
