Robert Preston Hall was 18 when he vanished from his Arlington, Virginia home. He was last seen on January 14, 1976, driving a green 1970 Ford Mustang with Virginia plate HAW-198 and wearing a brown corduroy jacket and blue jeans. The next day his disappearance was reported to the Arlington County Police Department.

Hall is described as six feet four inches tall, about 235 pounds, with brown hair and brown eyes. Neither he nor his Mustang have ever been found. The case was entered into the National Missing and Unidentified Persons System in January 2016, and Arlington County police have kept the investigation open.

Does anyone have information about Hall, the Mustang, or sightings in Arlington around mid-January 1976?
