ST. LOUIS -- Twenty years after a series of murders by the so-called "I-70 killer," police in one St. Charles are releasing new information in the cold case.
Thursday marks the 20th anniversary of the death of Nancy Kitzmiller, 24. She was found by customers at Boot Village in St. Charles, where she worked.
Kitzmiller was one of six people killed in five Midwestern cities in April and May of 1992. Four of the murders were at small shops along Interstate 70 -- two in Missouri, two in Indiana. The other two were at a bridal shop near Interstate 35 in Wichita, Kan.
St. Charles police say that based on ballistic evidence and witness statements, the gun was .22-caliber, possibly an Intratec Scorpion or an Erma Werke Model ET 22.
