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.

A teacher who authorities say admitted to fatally stabbing a couple he didn’t know who were hiking with two of their children in an Arkansas state park is expected to have his first court appearance.

Police in Arkansas released a new photo on Tuesday to go along with a previously released sketch of a man they want to question in connection with the deaths of a married couple who were attacked and killed while hiking with their two young daughters at a state park in the state’s Ozark Mountains.
