I actually doubt he is the REAL boss, in my head he's just a puppet, set up by someone (most likely Nicholas Santora, Tommy DiFiore or Asaro) to fool the FBI. Just put the word out on the street that Michael Mancuso is the new King, the few agents that still focus on Organized crime might just focus on him instead of the real boss, like the Genoveses have done for decades.

I can't imagine that psychopat being in charge of anything larger than a noodleshop. Either it's an setup or the cops have got it extremely wrong, LCN wouldn't place a wife-murdering high-profiled guy like him (he's done years for manslaughter and more) at the top of the pyramid. But he's incarcarated now until 2020 I think so who gives a fuck, Tommy DiFiore seems to be the boss now, and he'll probably stay in that position.
