Actually Henry Borelli has been up for a parole hearing but hasn't shown up because when the judge sentenced him in the 80's he said he recommended that he never recieve parole and if a judge says that you pretty much have no chance. Also its hard to imagine any of those guys from the Demeo crew being very truthful because they were so fucked up.
I forget what book it was, I think it was the book about Casso, it said Demeo was very paranoid from doing loads of coke in the last years of his life. I don't know if it's true or not, but you figure with all the crazy stuff they were doing, it wouldn't surprise me they did a lot of drugs and booze to cope. The guy who flipped on Tommy Pitera got pulled over for driving drunk and drugged up. He started talking to the cops about the chopping up bodies and other stuff eventhough he was only in jail for driving drunk, he claimed he was druging and boozing heavily because of the stuff he saw Pitera do. Wasn't Pitera the one who killed Willy Boy Johnson for Gotti?
