It has now been a week since 55-year old Julia Christine Devline, a lecturer in economics at the University of Virginia, was last seen. Her white Lexus sedan was found on Saturday wrecked off Skyline Drive in the Shenandoah National Park. SNP Specialist Claire Comer says they concluded their search in the highest probability areas on the ground, and have been working behind to investigate what may have happened. She says so far, they have no answers.
