The news reports state that he was at his grandmothers home in Abbeville, SC. He became upset about something and she asked him to go out to her fenced yard to “cool off”, and that’s when he disappeared. There was a reported sighting of Adam walking on one of the nearby rural roads, but I’m not sure of the name of the neighbor who reported this info.
Adam’s mother and grandmother have stated this is a close knit community where the neighbors all know one another.
I think there are links to the media reports in the thread above.
My worries are that the area is very rural.
