Michael Franzese grew up the son of Sonny Franzese, the notorious underboss of New York's violent and feared Colombo crime family. At his most affluent, he generated an estimated $5 million to $8 million per week from legal and illegal business. It was a life filled with power, luxury...and deadly violence. When he was 35, Fortune Magazine listed Franzese as number 18 on its list of the "Fifty Most Wealthy and Powerful Mafia Bosses," just five spots below John Gotti. He quickly became the target of Manhattan"s federal prosecutor, Rudi Giuliani who promised Franzese 100 years behind bars upon indicting him on racketeering charges. Giuliani came up empty-handed.
