Christopher Niehoff, a 31-year-old motorist from Eureka, was driving a 2005 Dodge Ram on Thursday afternoon, and ran into the back of the 2009 Hyundai Santa Fe being driven by Marggie Bonner, 30, of Kirkwood, according to Missouri State Highway Patrol records.
Bonner and another driver, Joseph Kemper, had been stopped for traffic. The rear-end jolt from Niehoff's pickup caused Bonner's vehicle to hit Kemper's 1999 Chevrolet S10.
Kemper is a 34-year-old resident of DeSoto.
The accident occurred at 3:15 p.m. on Missouri Route 109 at Emerald View Parkway in Eureka. All three motorists were wearing seat belts, according to authorities.
Bonner was taken by Eureka Fire Protection District paramedics to St. Clare Hospital for treatment of moderate injuries.
Both of Niehoff's and Bonner's vehicles were totaled. Kemper was able to drive his pickup from the accident scene.
