On May 3, 1992, Nancy Christine Kitzmiller, 24, was found shot execution-style in a rear office of Boot Village, a western wear store at 2079 Zumbehl Road in Saint Charles, Missouri. She had been working alone; customers discovered her about 2:30 p.m. Investigators reported no signs of a struggle or sexual assault, and Nancy’s purse was left behind while only a small amount of cash was missing, suggesting robbery was a secondary motive.

Ballistic evidence linked the .22 caliber pistol used in her killing to a series of spring 1992 homicides across the Midwest attributed to the unidentified I-70 Killer. Witnesses described a white male, about 5 feet 7 inches to 5 feet 9 inches, slender to medium build, sandy blond or reddish hair and lazy eyelids; composite sketches were released but no arrests were made. Police briefly investigated Donald Waterhouse but later cleared him.

Anyone with memories of that afternoon or information about the suspect is asked to come forward.
