I honestly don't believe that they have an official boss. It's more difficult for the feds to pinpoint someone as "the guy" for the purposes of building a major case. But for all I know, they could have a boss and half the family doesn't even know about it. That's just the way they've always been.

Speculation (both by the feds and, for what it's worth, guys "in the know" on this board) has held for the past several years that the family is run by some sort of panel consisting of some combination of Barney Bellomo, Quiet Dom, Ernie Muscarella, Larry Dentico, and, now that he's a free man again, Danny Leo.
