Two people were injured in a rollover along Great River Road in Clayton County Sunday night. The Iowa State Patrol says a car headed south lost control and went into the ditch, hitting a roadsign and some trees before flipping over. Two people inside the car were trapped and had to be freed by emergency personnel. The driver, 85-year old Roy Siegworth of Dubuque, was seriously injured. He was airlifted to Gundersen Lutheran Hospital in LaCrosse. His passenger, 82-year old Shirley Siegworth, was also injured and transported to Prairie du Chien Memorial Hospital.
