On the night of Saturday, August 4, 1990, 11-year-old Heidi Seeman was walking home in northeast San Antonio after spending the night with a friend. The friend last saw Heidi at Stahl Road and Willow Run, having walked her halfway. A witness later reported seeing a shiny red car with tinted windows and a thin red stripe driving suspiciously in the neighborhood just before Heidi was taken.

On Saturday, August 25, 1990, Heidi’s decomposed remains were found on an isolated property off County Road 220 in Hays County, Texas. Medical Examiner Dr. DiMiao ruled the cause of death a homicide. Investigators have developed several leads and suspects over the years but say there has not been enough evidence to file charges.

Anyone who lived in the Stahl Road and Willow Run area in August 1990, or who recalls a shiny red car seen around that time, is asked to come forward with information.
