LOUISVILLE, Ky. (AP) -- A 14-year-old Louisville girl whose feet were severed by an amusement park ride last summer says the accident has changed her life forever.

Cables on the Superman Tower of Power ride at Six Flags Kentucky Kingdom snapped on June 21, shearing off Kaitlyn Lasitter's feet. Doctors at Vanderbilt University Medical Center in Nashville, Tenn., reattached the girl's right foot, but her left leg had to be partially amputated.

The teen says that she isn't the person she was before. She says she's afraid now, and fears for her life when she gets in a car or elevator.

Lasitter spoke in Washington, D.C. Wednesday in support of a bill sponsored by Congressman Edward Markey of Massachusetts to give federal safety regulators powers over amusement parks.

Lasitter's family is suing the park, claiming it failed to maintain the ride and ensure riders' safety. Six Flags has denied liability.
