A Six Flags Magic Mountain roller coaster was reopened Thursday as state investigators continued an inquiry into the June 3 death of a woman who visited the amusement park.
After 10 days of testing the Goliath ride--which opened last year--investigators determined that it was operating properly, said Dean Fryer, spokesman for the state Department of Industrial Relations.
An investigation is expected to continue for at least four more weeks into the cause of death of 28-year-old Pearl Santos of Fontana. She was found collapsed in her seat after riding the roller coaster, which plunges at speeds up to 85 mph, and she was pronounced dead a short time later.
A preliminary autopsy found that Santos had a preexisting aneurysm that may have caused a blood vessel to the brain to burst. However, coroner's officials said the exact cause of death has not been determined.
State safety and health inspectors are awaiting a final coroner's report, among other studies, before concluding their investigation, Fryer said.
