From everything I've read, Marcello appears to be a really tough, hardcore individual. I would like to know more about his tenure in The Outfit but information on the Internet is limited. Family Secrets stuff and a little more is all I've found.

Any chance he might "cooperate" in order to get his life sentence reduced? And if he did cooperate, does he have enough info to leverage the Feds ? Like I said, he seems to be very hardcore and my questions are purely speculative.
