Charles Duane Gustafson, 72, was last seen October 11, 2006, while elk hunting with family in Medicine Bow National Forest near Arlington, Wyoming. The hunting party split up that day; Gustafson was expected back at camp in the evening and never arrived. His family fired three shots into the air and heard what they believed were three shots fired back but could not locate him.

He had become disoriented the day before and had been found by a logger. At the time he went missing he carried a Winchester 30-06 rifle, a map, GPS, water and other hunting gear. He was in good health, had Air Force wilderness survival training, and had hunted the area for more than a decade, though he was known to occasionally suffer episodes of mental disorientation. Searches by law enforcement with dogs and helicopters continued into snowy, near-freezing conditions but turned up no trace.

The case remains classified as lost/injured missing and investigators report no new leads. Does anyone who hunted the Medicine Bow area around October 2006 or knew Gustafson have information that could help explain what happened?
