No, it doesn't say that.
Nope, it doesn't say that either. It says that's where she was pronounced dead. We have no idea when she arrested and how long they resuscitated her.
How about tension pneumothorax and pericardial tamponade?
We don't know that.
The ambulance arrived 9 minutes and 19 seconds after the call was dispatched, not after the 911 call was made. (I'm not sure who did the math in the article. 4 minutes 47 seconds + 4 minutes 32 seconds = 9 minutes 19 seconds, not 8 and a half.)
Again, we can't know how the time frame may have improved if an ambulance had been sent at the time of the 911 call.
But according to the article, the helicopter didn't get called until after the ambulance arrived. So much for first responders recognizing the acuity of the situation.
Precious time was wasted here, and the child died. Until a medical examiner (a physician) determines the cause of death (more specifically than just being run over) saying that she would have died anyway is very premature.
