The witness saw the suspect carry a backpack and run into the QuikTrip. He told police the suspect dragged the clerk toward the front counter and held a knife to her throat.

No criminal charges will be issued as the St. Charles County Prosecuting Office officially cleared the armed witness of any wrongdoing in shooting the suspect.
