One other thing about Manna - if you read Remo Franceschini's book he says that he didn't believe and had evidence that Manna didn't kill or plot to kill Irwin Schiff that it was someone else
That's interesting; but who was it, according to the book?
A guy by the name of Angello Castelli that I have yet to find any information on but Castelli ended up getting killed himself.
