Boy dies on Disney rollercoaster

ORLANDO, Fla., June 29 (UPI) -- A boy was declared dead Thursday after riding the Rock 'n' Roller Coaster at Disney-MGM Studios theme park in Orlando. Fla., reports say.

The cause of death was not immediately known, authorities told the Orlando Sentinel said. The boy was estimated at between 7 and 12 years old. It was not known whether he was with anyone.

The coaster, known for its fast start and pulsating Aerosmith soundtrack, is the second-fastest ride at Disney, with a top speed of 57 mph, and tied for the tallest.

The Sentinel said records show this would be the seventh person to die at a Disney attraction since the Christmas season of 2004.
