ALAMOGORDO, N.M. (AP/KXAN) – A 15-year-old boy who has autism has been found safe after he wandered away from his family during an outing at White Sands National Monument and spent the night among the sand dunes.

Monument officials say the teen was spotted Monday morning by a U.S. Air Force Black Hawk helicopter crew. He was walking in the dunes about six miles from where he was last seen.

Authorities say he was in good condition.

The teen and his family had spent Sunday sledding and picnicking at the southern New Mexico monument. They are from El Paso, Texas.

At about 3 p.m., the family realized he wasn’t with the group.

The search was given high priority due to the teen’s autism condition and the impending darkness.

More than 100 searchers, including state police, the U.S. Border Patrol and the Air Force, were involved in the all-night operation.
