Lemuel Lem Ray Addington was 52 when he was last seen in Yreka, California, on July 10, 1998. Officers had approached him that day for trespassing at an Amerigas facility off Highway 3; he was later seen walking toward Deer Creek and into a nearby field. Extensive searches by local authorities and search-and-rescue teams turned up nothing.

Addington was about 6 feet 1 inch and 130 to 140 pounds, with brown hair and gray eyes. At the time he disappeared he wore blue jeans, a blue-green plaid shirt and brown boots with green laces, and he carried a red-handled folding knife and a worn wallet. There was a possible, unconfirmed sighting in November 1998 near a Goodwill store in Medford, Oregon, but no confirmed trace has emerged since.
