Stephen Michael Mason, known as Mike to friends, was 52 when he disappeared from the Olympic National Forest near Sequim, Washington. He was last seen on June 20, 2006, at the Dungeness-Forks Campground, a site he regularly used. In the days before he vanished he and his wife had an argument that led her to leave the campsite; the next day he visited a friend who drove him back after agreeing to return the couple’s vehicle and the wife’s purse to her. That visit is the last confirmed sighting.

A missing persons report was filed on June 29, nine days after he was last seen. A two-day search that included ground teams and Coast Guard helicopters turned up a cache of Mason’s food and supplies at the campsite but no sign of him. He worked as a handyman at the local VFW post and was not known to disappear without contact; his family cites the missed Mother’s Day call as especially out of character. The FBI has said there is no link between this disappearance and Israel Keyes. No suspects have been publicly named and no arrests reported.

Anyone who knew Stephen’s routines, companions, or movements around Sequim in June 2006 is asked to share information with the Clallam County Sheriff’s Department.
