There's a lot of speculation going around about what happened to him. There's no doubt he tried to take over the Rizzuto crime family when he was deported to Canada. As to who rubbed him out from what I've heard, it was a rival family connected with the Ndrangheta, or possibly Vito Rizzuto ordered him out while in jail. I don't think the Bonanno's had anything to do with it, when he was deported that was kind of 'it' for him. But let me see if I can find an article.
