Four people from Arkansas were hurt, two seriously in a one-vehicle accident Monday morning in Madison County. The highway patrol says the crash happened on Highway 67, a half mile south of Cherokee Pass when 25-year-old Ricki Quillen failed to make a right-hand curve with her Ford Explorer. The vehicle ran off the road, struck an embankment, and overturned, throwing the two adults out of the vehicle. Quillen and 23-year-old Timothy Quillen were seriously injured. They were both flown to Mercy Hospital in St. Louis. Two children who were passengers, a 14-year-old and a 2-year-old received minor injuries and they were taken to Madison Medical Center in Fredericktown for treatment.
