Two little girls led police to a man who killed their parents in front of them while they were out on a family hike, according to police.

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.

James Andrew McGann, 28, was arrested at 4:57 p.m. local time on July 30 at a business in Springdale, Arkansas, state police said.
