I'm kind of annoyed at all of the skepticism shown for this story. The fact of the matter is this girl was locked in a malfunctioning car. That was why she could not escape.
Car windows are not fragile, they're not supposed to be. They're supposed to be fortified to prevent any minor thing from breaking it. It is not easy to gain the force strong enough to break a car's window from the inside because your space is limited.
I looked up the model and though I don't know what year the car is, here is a 2012 just to be general.
This is not a big car. We know she's 84 pounds so she's pretty light and likely did not have the necessary strength required to successfully break the window. Depending on her height, she may not have had enough space to as well.
And if the car didn't have anything solid and big enough she could use to hit the window with, would her hands and feet have been enough? She could bang on the windows all the likes, but unless someone is nearby, there's no hope for her.
This malfunction disabled her very last option for calling for help: the horn.
This freak accident basically removed all options for her escape. I think the most she could have done, if the car has this feature, was put the backseat down, enter the trunk, and use the emergency release handle but not all cars may have this feature, it may have been done in a different way, and a 14-year old may not have such knowledge of it yet.
So I'm really not understanding the skepticism in this particular story. Did I even see someone bring up the possibility of drugs?
