ORLANDO, Fla. >> The parents of a 14-year-old boy who fell to his death from a 430-foot drop-tower ride in central Florida’s tourist district sued its owner, manufacturer and landlord on Monday, claiming they were negligent and failed to provide a safe amusement ride.

The parents of Tyre Sampson said in the lawsuit filed in state court in Orlando that the defendants failed to warn their 6-foot-2-inch, 380-pound son about the risks of someone of his size going on the ride and didn’t provide an appropriate restraint system on the ride.

While most free-fall rides have a shoulder harness and a seat belt, the Orlando Free Fall ride had only an over-the-shoulder harness. Adding seat belts to the ride’s 30 seats would have cost $660, the lawsuit said.

At the time of the accident last month, Sampson was on spring break, visiting from the St. Louis area.

“The defendants in Tyre’s case showed negligence in a multitude of ways,” said attorney Benjamin Crump, who is representing Sampson’s family. “From the ride and seat manufacturers and the installer to the owners and operators, the defendants had more than enough chances to enact safeguards, such as seatbelts, that could have prevented Tyre’s death.”

An attorney for the ride’s owner, Orlando Slingshot, said the company was continuing to cooperate with state investigators into what happened.

A spokesman for the landlord, ICON Park, didn’t comment immediately on the lawsuit.
