Authorities at Grand Canyon National Park say they are scaling back the search for a Texas man who has been missing for nearly three months. Park officials say 49-year-old Charles Lyon of Tyler was last seen at a hotel in Tusayan on June 10. They say Lyon abandoned his vehicle on the canyon's South Rim along Desert View Drive near Lipan Point on or around June 11 and was believed to be traveling alone. Beginning on June 11, crews searched extensively by ground and helicopter in that vicinity but there was no sign of Lyon. Park officials say the search will continue in a limited and continuous mode.
