posting a message on a Facebook site that "no stone will go left unturned". The New BoyZ Support Crew Facebook site is one that Giovanni often contributed to and friends of the 22-year-old - who was ambushed with his father Vince Focarelli in a suburban Dry Creek street about 9.45pm last night - have started to pay tribute to the shooting victim. The full message, posted about 2pm, reads: "Why do bad things happen to good people? No stone will go left unturned. RIP Giovanni". The first tribute messages to the son of the former head of the Comanchero Motorcycle Club Adelaide chapter were posted on the site early yesterday morning.
