An autopsy will not be performed on a 10-year-old girl who lost consciousness after taking the Revolution ride at
The family of Jasmine Martinez, of Somis, objected to an autopsy because of "religious preferences," said Ed Winter, spokesman for the Los Angeles County coroner's office.
Winter said that because no autopsy will be performed, the coroner's office cannot determine a cause of death.
Jasmine died Saturday at Cedars-Sinai Medical Center, a day after she was found unconscious. Winter said a doctor at the hospital signed the death certificate indicating that the girl is believed to have died from natural causes.
A spokeswoman for Cedars-Sinai said she could not comment on the death certificate or the cause of death, citing privacy concerns.
Jasmine had just finished riding the looping roller coaster Friday when she lost consciousness, according to officials at the theme park in Valencia.
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 was breathing but unconscious when the ride ended and came into the ride station, where guests load and unload. She was treated at the scene before being airlifted to the hospital. Later that day, state officials with Cal/OSHA determined her condition wasn't related to the ride and the attraction was reopened Monday night.
"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 preexisting condition."
Revolution, which opened in 1976, climbs up a 113-foot hill, then swoops through slopes and a long, steep straightaway to a 90-foot 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, 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.
