I remember my dad had a book on the subject but I don't remember the title. But I remember reading parts of it AND it was about an old mob leader from New Orleans named Carlo somethin- (his last name began w/ an "M"- Im thinkin Marcello or something). Hes in jail now but the theory in the book was that he was behind it.

I'll try and track down the book and get some more info about it up
