A 10-year-old girl who lost consciousness after riding a roller coaster at an amusement park in Valencia, Calif., has died, officials said on Monday.

Jasmine Martinez had just exited the Revolution ride at Six Flags Magic Mountain on Friday when she became unconscious, the Los Angeles Times reports. She was airlifted to a hospital and later transferred to another, where she died on Saturday.

The cause of death has not yet been determined, according to the Los Angeles County coroner’s office, and officials have said no evidence indicates it was related to the operation of the ride. Magic Mountain has nevertheless temporarily closed the ride while the incident is reviewed. NBC4 News reports the ride, which can clock speeds of 55 mph, has been operating at the park since 1976.
