LITTLE ROCK, Ark. (AP) — Arkansas police charged a 28-year-old schoolteacher in the killing of a married couple who were hiking with their children at Devil’s Den State Park, finding him in a nearby city after a five-day search and public pleas for trailgoers to look through their photos.

While on a family hike at Devil’s Den State Park on Saturday, Cristen’s husband Clinton was ambushed and stabbed by an attacker, according to Arkansas State Police. First, investigators say, she ran away to get their young daughters to safety. Then Cristen Brink went back to try to save Clinton.
