St. Charles County Sheriff Tom Neer said that Richard Heeter, 61, from the Wentzville area, shot at sheriff's deputies in an area near Sommers Road and Hwy. N near the Lake Saint Louis/O'Fallon border.
The deputies returned fire. One deputy was shot in the wrist, and the other was shot in the arm. Heeter escaped and a manhunt of the area continued until he was located just after 5:30 a.m. in the same area as the shootings.
The suspect refused to comply with officers and stabbed a tactical officer in the shoulder. Other officers then shot and killed Heeter.
All three injured officers were taken to hospitals and treated.
