Georgia Insurance and Safety Fire Commissioner John King confirmed state inspectors are on the ground examining equipment and coordinating with park leadership. Following the death of 42-year-old Hassan Kariem, Six Flags immediately evacuated the Cobb County park and shut down nine similar roller coasters at its locations across the U.S. and Canada. Safety and liability analysis What they're saying: Attorney James Murray, who previously represented a woman critically injured by a flying metal part on the Top Thrill Dragster at Cedar Point, noted that state, park, and manufacturer inspectors face a complex review process. They'll look at the park, were they following the proper safety protocols. Were the employees following the proper safety protocols, Murray said. They'll also look at the manufacturer of the ride.
