Why? Matthews had been traveling north on Interstate 25 when he talked to his girlfriend, Debra Hughes, who lived in Penrose, Colorado. When Matthews didn’t return home, Hughes called search and rescue. A state game warden found his truck lodged in a snowdrift four days later about 44 miles off a remote side road, U.S. 64.
