Update: Missing Madison teen found unharmed

GREENEVILLE, TENNESSEE - An autistic teen from Madison County, North Carolina who had been missing since Saturday was found unharmed late Monday morning in the edge of Tennessee.

Devon Dakota Williams, 13, was found by a Greene County, Tennessee deputy at about 11:30 a.m. Monday on Old Asheville Highway (Tennessee Highway 70), just inside the Tennessee state line, Madison County Sheriff's Office chief deputy Michael Garrison said.

The Greene County deputy spotted the boy when he came out of the woods to the road, Garrison said.

"He was hungry," Garrison said. "We gave him something to eat and drink. He was also wet. It's rained like crazy the last few days. But he's doing well."

The boy was last seen Saturday near his home on N.C. 208 a short distance away in the Little Laurel community. N.C. 208 turns into Highway 70 in Tennessee. The boy is autistic and non-verbal, the family said in a Facebook post. He apparently had been lost in the woods.

About 80 rescue personnel from Tennessee and North Carolina were involved in the search since Saturday, with helicopter support from the N.C. Highway Patrol. Search teams, including canine units, had scoured the steep terrain in the area.

"This is rough terrain," Garrison said. "It's thick and very rugged."

Area churches pitched in to provide meals for the search teams, which were made up of sheriff's deputies from both states, firefighters from several counties and crews from a number of state agencies, he said.
