Muehlberg was already serving a life sentence for the 1993 murder of Kenneth Atchison when new DNA evidence linked him to the murders of four additional victims. Atchinson's body was found in a makeshift coffin in Muehlberg's basement, while other victims were found in various spots around St. Louis disposed of in containers such as garbage cans and wooden boxes. Another victim's body was found stuffed between two mattresses.
