They say Kodak was the driver, and officers discovered weed on him ... after further inspection of the vehicle they also found a Glock 9mm pistol which was undeclared by anyone in the Escalade. There was also a Porsche traveling with Kodak's team with 3 other individuals. The driver of the Porsche copped to having 2 loaded handguns and a third was found in the trunk ... aaaand more marijuana. Stetson President and Madarrow Smith were both arrested for criminal possession of a weapon ... Jeantony Saintmelus -- who was driving the Porsche -- was booked for criminal possession of a weapon and possession of marijuana. While Kodak never made it to his show in Boston ... his tour bus did, and angry fans surrounded it after getting word he was a no-show.
