Dion Mike Napier was 48 when he was last seen in Seattle on December 9, 2007. He was described as a white male, brown hair, green eyes, 5 feet 11 inches, and about 175 to 180 pounds. A photo from when he was 30 shows a mustache, small goatee and short beard; he has a quarter-sized birthmark on the back of his neck.

Reports place him in Seattle after a trip to Portland, Oregon, and there was an unconfirmed possibility he might travel to Alaska. His disappearance produced few concrete leads; the Seattle Police Department is handling the investigation. The case was reported on August 28, 2009, and a NamUs entry was created on December 9, 2009. An age-progressed image was later made to suggest how he might have looked around age 50.

Who saw Dion in December 2007 or remembers contacts, travel plans or sightings around Seattle, Portland or en route to Alaska?
