Ken Rosenberg

in 1986 Vice City by setting up a drug deal between the Vance Crime Family's Victor and Lance Vance and Forelli Family representatives Tommy Vercetti, Harry and Lee. The deal was ambushed but Rosenberg and Vercetti escaped, with Rosenberg hiding in his office, even missing Colonel Juan Cortez yacht party, instead sending Vercetti to meet the man who set up the deal and later to find out who ambushed the deal. Rosenberg had, before the ambushed drug deal, been representing Giorgio Forelli, who was facing charges of fraud, and sent Vercetti to intimidate two jurors. He had also begun representing real estate mogul Avery Carrington, who Vercetti later began to work for after causing a riot at the Spand Express depot.
