Robert Grey Pinkerton, 34, was last seen on September 26, 1997, in Isla Vista, California. He had been living a transient lifestyle at the time of his disappearance. Pinkerton was described as 6 feet tall, weighing about 175 pounds, with brown, shoulder-length hair and a full beard with graying around the chin. He also had several distinctive features, including a chipped upper front tooth and a metal pin in one of his wrists, although the specific wrist is unknown. He had a 2-3 inch scar on his stomach.

His father reported him missing, and the case was treated as a voluntary missing adult. Pinkerton has not been seen or heard from since, and there have been no significant developments in his case.
