i doubt it has been cut by the fire bridage, the near side wing with the a pillar still attached and what looks like the near side chassis leg attached to the corner as well is up in the air. Something has gone through the bulk head and totally severed it, the roof area and near side rear looks intact, fb usually cut the roof off and at the a post and the doors off and cut the and pull the person out from the roof area, I cannot imagine why the fb would cut through what is the biggest piece of metal on the car, the bulkhead.
Ive seen a few as bad as that, never a good thing to see
