Donald Gordon Jessup, 60, was last seen on or about December 15, 2004, in the Enumclaw area of King County, Washington. His disappearance was treated as suspicious from the start. Jessup was a former president of the Gypsy Jokers Motorcycle Club, a detail that figured prominently in the investigation.

The King County Sheriff’s Office pursued leads tied to outlaw motorcycle gang activity and eventually focused on a member of a rival gang. That individual was charged and convicted of Jessup’s murder, but Jessup’s body has never been recovered. The sheriff’s office continues to list him as a missing person, and his family remains without the closure of a known resting place.

Did anyone in the Enumclaw area at the time have information about Jessup’s last known movements or contacts around mid-December 2004?
