Millions of people travel along the 160,000 miles of U.S. highways each day, often passing people they will never encounter again. ID's true-crime series, "Highway to Hell," explores cases involving the drivers who harbor deadly intentions and the hapless travelers who will never reach their destinations. Episodes tell the stories of long-haul trucker Bob Nelson, 59, who fails to return home to celebrate his 25th wedding anniversary, and the shooting death of Dr. Gulam Moonda on the Ohio Turnpike.
