Arkansas State Police say Clinton David Brink, 43, and Cristen Amanda Brink, 41, were killed while hiking with their two school-age daughters at the park Saturday afternoon.

The couple was "attacked" while hiking in Devil’s Den State Park in Arkansas. A suspect was seen driving with tape on his license plate, authorities said.
