Correct, it was better to wait for the HEMS doctor and amputate her leg, then rescue her out very fast with the very possibility that blood prop was shooting loose and kills her. This can happen when a leg or arm is stuck for long time and is cutting loose, then the blood prop (Dont know the right name) is shooting from the arm/leg to the brain.
If she did died on site then we had towed the car to the fire station to take the time we need to do it with high care so the morgue crew could fix the most for the eye.
Shit, you can talk to me any time.
