No, seriously.
The way I've understood it happened:
She was in front of the bulldozer, between the bulldozer and its target.
For some reason she did not move out of the way.
The bulldozer ran over her.
I think everyone (Israelis, US, Pals) agree on that version.
Then there are some that say that she fell, that the driver didnt see her, that the driver did see her etc etc.
