ORLANDO, Fla. (AP) -- An attorney for three passengers who were riding a Florida roller coaster when it derailed last week says his clients could have lifelong injuries.

Attorney Matt Morgan said at a news conference Monday that he has hired two ride-safety experts to evaluate what went wrong with the Sand Blaster roller coaster when it derailed last Thursday on the Daytona Beach Boardwalk.

Morgan says his clients will contemplate a lawsuit if the ride's insurance companies fight paying them.

Morgan's clients all come from Kentucky. They were visiting Daytona Beach as part of a work trip.

They include Amanda Bostic, one of two riders who plummeted 34 feet (10 meters). They also include a rider who was forced to hang from the ride until being rescued.
