A University of Virginia economics lecturer has disappeared in Shenandoah National Park, prompting an extensive search.

Fifty-five-year-old Julia Christine Devlin was last seen in Charlottesville on July 14; security footage showed her white Lexus sedan entering the park late on that day.

On Saturday, investigators found her car wrecked and abandoned in the southern portion of the park.

The park said its own search and rescue teams are being assisted by the Virginia Department of Emergency Management and urged the public to avoid the area. “Due to the ongoing investigation and search dogs activity,” the park said, “the Park is not recruiting volunteers.”

Devlin is described as 5 feet 7 inches tall, 150 pounds, with dark blonde hair.
