Records differ on the last known location: Iowa documents list Keota as where he was last seen, while the National Center for Missing & Exploited Children lists Grand Canyon, Arizona. That split reflects how Aaron’s disappearance unfolded rather than a single clearly documented moment when he vanished.

Aaron was described as about six feet to six feet two inches tall, 145 pounds, with brown hair and brown eyes, a one-inch scar on his right wrist, moles on his back, a pierced left ear, and eyeglasses. Family accounts say he left in a family car that was later found in the Iowa City Public Library parking lot; another vehicle linked to his travels was found abandoned along the Kewash Nature Trail.

Aaron was not entered as a missing person until April 30, 1993, which his family says meant the first months of his travels passed without a wider missing-person investigation. The Keokuk County Sheriff’s Office remains associated with the case and his files appear in NamUs (6499) and NCMEC (772107). If anyone knew Aaron, saw him in Arizona or en route to Colorado, or has information about the girl he intended to meet, please come forward.
