Shelby was living with and caring for his great-grandmother in the 6400 block of East Lowell Larimer Road in Snohomish, Washington in the summer of 2004. He was last seen at the residence of a family friend, Rob Wolf, on Cemetery Road in the 900 block of 135th Avenue southeast in Machias, Washington on July 26, 2004. The home is about a mile from Shelby's great-grandmother's home. His scooter was left at Wolf's home where he was last seen, and all his other belongings were left behind at home, except his laptop, which has never been found. In January 2007, Shelby was reclassified from a runaway to an endangered missing child. Wolf, who always maintained his innocence in Shelby's disappearance, is now deceased. Shelby's case remains unsolved.
