Jon Evans Ottesen was 61 when he was last seen on September 5, 1999, in Las Cruces, New Mexico. He had been preparing for a hike into the Black Range of the Gila National Forest and was described as a white male with graying hair, blue eyes, and a beard. At the time he wore tan corduroy pants, a dark windbreaker, hiking boots, a hand-knit ski hat, and glasses.

His Ford pick-up truck was later found parked along a well-traveled road in the Gila National Forest, confirming he reached the area he intended to explore, but there was no sign of him. An intensive search of the surrounding wilderness turned up no clues. The Las Cruces Police Department keeps the investigation open, but decades of silence have left the trail cold and his fate unknown.

If anyone had contact with Jon around September 5, 1999, or remembers seeing his truck in the Black Range, please share what you know.
