I think it's possible she had a heart attack once she was flung from the ride and was dead before she hit the ground.
The coroner would be able to tell if she suffered a heart attack by heart muscle damage. Sometimes, heart muscle damage can be seen with the naked eye if it is severe enough. Other times it isn't seen until under the microscope. They would be able to tell if her heart was stopped by the physical injuries. Basically, if there is no bruising to the body her heart was no longer pumping prior to hitting the ground.
This.
Yes. A medical emergency is not going to cause her restraint to fly up. That's why I quoted that part of the article, because I think it's bullshit the topic is even being discussed by Six Flags.
"Well, if the woman hadn't of had a heart attack her restraint would not have flown up and she would still be alive today.' Blame it on the rider.
