Leighton Thomas Willis, 60, vanished after a series of puzzling events in spring 1999. On March 8 he was in a single-vehicle crash on Interstate 35 at mile marker 203 in Noble County and left the scene for reasons that are not explained. The next documented contact came more than a month later: a Wichita, Kansas, police officer spoke with him on April 24, 1999. That was the last known contact. His family reported him missing on April 26, and he was entered into NCIC on April 27.

Leighton was a Caucasian male, five feet seven inches tall, about 155 pounds, with brown hair and blue eyes. No clothing description at the time of disappearance is recorded in the available details. Noble County Sheriff’s Office handled the case, which stalled after those sparse leads and grew cold.

There is no public explanation for why he left the accident scene or what happened after the April contact. Did anyone see him in Wichita on or after April 24, 1999, or have information about his movements following the crash?
