Before dawn in March 1997, a police captain was patrolling the outskirts of a small town in North Carolina. He saw a Jeep parked on the shoulder of the highway with its headlights on. He pulled over, and as he walked closer to the Jeep, he heard the engine running. The driver's side window was rolled down, and there was no one inside. But just then... a cell phone on the passenger seat started ringing.
