Cape Girardeau police responded to an accident Friday afternoon on Interstate 55, stopping traffic for about 15 minutes when a car rolled over on the northbound side near mile marker 93, said Sgt. Barry Hovis, spokesman for the police department. The driver, a 20-year-old woman, was ejected from the car and pinned beneath it for a brief time, but other people were able to move it off her, Hovis said. She was badly injured and transported to a Cape Girardeau hospital. The front-seat passenger, the driver's husband, was also injured and taken to the hospital, Hovis said, while a 17-year-old passenger was treated at the scene. The cause of the accident is not yet known, Hovis said.
