LITTLE ROCK, Ark. (AP) — A teacher admitted he fatally stabbed a couple he didn’t know who were hiking with two of their children in an Arkansas state park, authorities said Thursday, after a five-day search and hundreds of tips led to his arrest.

Clinton David Brin and his wife, Cristen Amanda Brink, were "fatally attacked" while out hiking with their two daughters at Devil's Den State Park, police said.
