I dont know guys where you get that info from regarding Matty being involved with Cohen, mostly because he was the second legit brother after Jim Capone who became a cop and later even changed his name. As for Matty, he has no kind of criminal records except for the murder that occurred in his bar during the mid or late 1940's, which in fact was a brawl between two drunk guests.

So my point is that the real individual who was connected to Siegel and Cohen was in fact John Capone, who possibly was under auspices of his brother Ralph, the one time boss of the Cicero area until the early 50's or before he went to Wisconsin. John was the guy who frequently went to LA and met with Dranga and the previous two guys. Proof for that was the questioning of actor George Raft regarding their relationship in that same territory.
