Greer Eugene Coursey was 47 when he was last seen on May 18, 2007, in San Luis Obispo, California. His abandoned vehicle was found by park rangers in Humboldt Redwood State Park soon after he disappeared, but there was no trace of him at the scene and no indications of foul play reported.

Coursey was about 5 feet 10 inches and weighed between 220 and 240 pounds, with brown hair, green eyes, and noticeable balding. In the period before he went missing he had quit his job, though it is not known whether that is connected to his disappearance. Despite searches, few details have emerged and the case remains unsolved.

Anyone with information about Greer Coursey’s whereabouts is asked to contact the San Luis Obispo Sheriff’s Department.
