Strange that he was never whacked for killing Gambino's nephew. They killed James McBratney from another gang who kidnapped 1 or 2 mafiosi earlier, thinking that Manny Gambino's kidnapping and murder was his doing as well, but then Senter was arrested and convicted for that, but he was never killed neither in jail nor after being released. Gambino made himself look like a fool by having the wrong guy killed and NEVER taking revenge on the "right" one. Usually, they "wash with blood" such "mistakes", yet Gambino wasn't worried about his reputation (even less about the nephew, as it seems)...
