Input: Question: When was the maker of the shoes Thorton was wearing at his time of death first established?  Passage:On a smuggling run from Colombia, having dumped packages of cocaine off near Blairsville, Georgia, Thornton jumped from his auto-piloted Cessna 404. In the September 11, 1985, jump, he was caught in his parachute and ended up in a free fall to the ground. His dead body was found in the back yard of Knoxville, Tennessee, resident Fred Myers. The plane crashed over away in Hayesville, North Carolina. At the time of his death Thornton was wearing night vision goggles, a bulletproof vest, Gucci loafers, and a green army duffel bag containing approximately 40 kilos (88 lbs.) of cocaine valued at $15 million, $4,500 in cash, six . gold Krugerrands, knives, and two pistols. Three months later, a dead black bear was found in the Chattahoochee National Forest that had apparently overdosed on cocaine dropped by Thornton.
