Arkansas State Police released a composite sketch July 28 of a man sought for questioning in the deaths of an Arkansas couple killed while hiking in a state park.

Clinton David Brink, 43, and his wife, Cristen Amanda Brink, 41, were hiking with their children at Devil's Den State Park on July 26 when they were attacked, police said. The man in the sketch was seen in the park that day, and investigators want help from the public in identifying him, police said.

The suspect remains at large. The couple's children, ages 7 and 9, were not harmed and are now with relatives.

"Clinton and Cristen died heroes protecting their little girls and they deserve justice," the couple's family said in a statement. "They will forever live in all of our hearts."
