There is the old way aka the lupara bianca,if there is no body,there is no crime,lok to the hoffa case: 40 and over years and nobody sentenced for his murder.
The guys the FBI suspected of the Hoffa disappearance were hounded by the FBI ever since. Tony Pro died in jail, I believe Russell Buffalino did as well. Frank Sheeran died a free man, but spent much of his life behind bars.
Provenzano was convicted in the Anthony Castellito murder and sent to prison,Bufalino went out of jail in 1989 after a 10 y sentence (and only because was the bufalino boss) Frank Sheeran made 9 years and was released due the poor health in 1991 and the other detroit mobsters made few or none time in prison and died free and old.
I believe you are correct Furio. But it was Buffalino, Sheeran, and Provenzano that were suspected, rightly or wrongly. Sheeran took responsibility and says Bufalino gave him the order. We will never know for sure.
