Kenneth Harker, known as Kenny, was 34 when he vanished from Sioux City, Iowa. He was last seen October 5, 1996; that same day his white 1977 Chevrolet Suburban was found on a gravel road, K-42, with doors open, tires flat, and the fuel tank empty, but no sign of Harker. He missed a planned meeting with his mother and she reported him missing on October 9 after finding his home deserted, his dog left without food, and his medications untouched despite a disabling traumatic brain injury from a prior crash.

Harker lived independently and loved motorcycles; he had recently dropped off a motorcycle engine at a local shop. Investigators have called the circumstances unusual and suspect foul play. Extensive searches, including on property linked to a mechanic connected to Harker, have turned up no trace. No arrest has been announced and the case remains unsolved.

Did anyone in the Sioux City area have contact with Kenneth around early October 1996 or know where he kept his motorcycle work?
