A rep for the Texas Department of Insurance, which regulates amusement park safety, said that the agency doesn't investigate accidents, but will re-inspect the roller coaster and issue a new report.
Six Flags itself will conduct its own investigation, and though there's no official word on what caused the woman to fall off the ride, onlookers said that there might have been problems with the safety restraint.
One witness told the Dallas Morning News that she had scene Esparza express concern about the safety of her seat.
“He was basically nonchalant,” Arlington resident Carmen Brown said. “He was, like, ‘As long as you heard it click, you’re fine.’ Hers was the only one that went down once, and she didn’t feel safe. But they let her still get on the ride."
"When it got in the air and started coming down, I don't know if she had a seizure or what, but she fell out of the cart and just fell out of the sky,” another witness told CBS 11.
Six Flags released this statement about their park's "internal" investigation into the matter:
Our thoughts and prayers are with the family. The investigation into the death at Texas Giant is still ongoing. We are working closely with authorities to determine the cause of the accident. The ride will remain closed. In addition, we have canceled the concert that was scheduled for today.
