You can find a definitive account of the Favara murder on Capeci's site, http://www.ganglandnews.com Just use their search engine on the opening page. "Underboss" is a pretty interesting book. The author knows his Mob subjects well. I was nauseated by Da Bull's rationalizations for his behavior, but that's part of the story.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
