John W. Simon was 58 when he left Houston, Missouri, on April 3, 2001, for a medical appointment at the Harry S. Truman Veterans Hospital in Columbia. He was driving a 1998 white Lincoln Town Car and was described as wearing blue jeans, a blue jean jacket, and black and white tennis shoes. He never arrived for the appointment.

His car was located abandoned and empty in the median of US Highway 63 and Highway 163, just south of Columbia. Beyond that discovery, the trail stops. Searches and an investigation by the Houston Police Department followed, but no significant leads have been reported and his whereabouts remain unknown.

The circumstances of his disappearance are undefined and there is no public explanation for what happened after the vehicle was found. Does anyone have information about John Simon’s movements that day or recalls seeing his car along Highway 63 or 163 on April 3, 2001?
