Charles Duke, 56, vanished after leaving a companion to seek help in Vogel Canyon, Otero County, Colorado, in mid-August 2003. On or around August 17 the veteran and a woman named Pam were driving a blue and gray minivan on an unpaved road toward the Vogel Canyon Picnic Area when the vehicle became high-centered. After wandering together for several hours, they separated around noon on August 18; Pam later was found by a rancher and returned to La Junta, but Charles was never seen again.

Search-and-rescue teams searched the area on foot and from the air without finding him. He was described as 5 feet 11 inches, about 155 pounds, with brown hair, hazel eyes and a scar on his right elbow; a Vietnam veteran who had been shot in service. The minivan was found two days after the separation, in a pasture some distance from where it had been stuck. Weeks later an arson fire severely burned a man and three children at a residence Charles owned in Ordway; investigators have not established a connection to his disappearance.

Does anyone who was in or near Vogel Canyon on August 17–18, 2003 have information about the vehicle, the route to the picnic area, or Charles’s movements that could help resolve what happened?
