Ok, here is what I can figure out from a report of a Licensing Tribunal in 2011 for a bar called Zucca, run in Hamilton by an Armando Fazzari. At this hearing it says police responded to an altercation between Carlo Fazzari, Luigi Fazzari and another patron. I know Armando and Carlo are brothers so I assume Luigi is either a brother, cousin or closely connected. Also, on a crazy sidenote, Carlo and his brother Armando actually appeared in an episode of Dragon's Den (Canadian original version of Shark Tank) pitching a push-up device. Check it out!
