I still dont think that it necessarily has to be someone who's unindicted who possibly flipped. I'd bet on Caldwell , but as seen in the Lenny Strollo situation, it may just be the black mob associate who holds his weight and takes it on the chin. But who knows at this point, it may just be someone who's still on the street. I dont think a guy like Migliore would give up the beans though, taking a plea isnt the same as ratting or giving up information on co-conspirators and friends, necessarily. I don't think the theory of it being Madonna holds much weight either.
