A 10-year-old girl who lost consciousness after exiting the Revolution ride at Six Flags Magic Mountain last week has died, coroner's officials said Monday.
Jasmine Martinez, of Somis, died Saturday at Cedars-Sinai Medical Center, a day after she was found unconscious, said Ed Winter, spokesman for the Los Angeles County coroner's office.
A cause of death has not been determined, Winter said.
She had just gotten off the looping roller coaster Friday when she lost consciousness, according to officials at the theme park in Valencia, Calif.
About 4:45 p.m., she was airlifted to Northridge Hospital Medical Center and later transferred to Cedars-Sinai.
"Our thoughts and prayers are with Jasmine's family and friends during this difficult time," the theme park said in a statement Monday.
The theme park said Jasmine came into the ride station unconscious. Later that day, state officials determined it wasn't related to the operation of the ride and reopened the attraction. But now that Jasmine has died, the ride has been temporarily closed as they review the incident.
"There is no evidence to suggest that this was in any way ride-related," the park said. "We do not know if there was a pre-existing condition."
Revolution climbs up a 113-foot hill, then swoops through slopes and a long, steep straightaway to a 90-foot-tall vertical loop.
The theme park says the thrill ride hits speeds of 55 mph as "you rocket through narrow curves, soar over peaks, and plow through a tunnel, banking left and right like a pro."
More than 45 million guests have "safely ridden" Revolution since it opened nearly 40 years ago, according to the theme park.
An L.A. Times analysis of more than 2,000 injury reports from 2007 through 2012 of theme parks across Southern California found most people suffered fainting, nausea and dizziness.
About 18% of the reports were related to motion sickness, including fainting, nausea and dizziness. It was followed by back and neck pain, ranked second at 16%. Head injuries ranked third at 12%. Theme park visitors were more likely to get hurt or sick on older attractions.
More women reported injuries than men, with most injuries occurring at roller coasters and water slides. The parks reported an average of about 350 injuries a year during the six-year period.
