Do You Know if It Was a Single Vehicle Versus Multiple Vehicles?

Police said every bone in her body had been broken. But it looked like she had been dragged one time, and that she had not been moving when the car ran over her five times. It is if you have the driver who hits a pedestrian, runs over the body and then circles back round, comes back or backs up. So this is where proving that its a single vehicle versus multiple vehicles would be part of the type of question i would be looking at.
