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.

Police believe Andrew James McGann, 28, fatally stabbed Clinton David Brink, 43, and his wife, Cristen Amanda Brink, 42, while hiking with their 7- and 9-year-old daughters in Arkansas’ Devil’s Den State Park on July 26. The children are now being looked after by family members.

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.
