Looks like a frontal flip, face through the windshield, brain on the hood event. Local Border Patrol Intel Chief told me they have no record of such an "accident."
Doesn't necessarily explain the blood dripping from the door frame though. The floorboards must have been filled up since both doors were dripping blood as I took the photos.
Finally the border patrol took my advice and started runnin them mother fuckers down rather than just ship them back so they can come right back a few hours later.
