From the photos, it's clear that she endo'd.
If you are really curious, I suggest that you remove the front wheel from her bike and take a drive to the crash site and see if the tire/wheel fits into the crack in the road surface. If that's a negative, and you don't see any damage to the front brake or spokes or fork which would indicate something jammed them, then I have no other ideas.
Running over the sort of animal that might run across a road would not typically cause her to endo so completely, and neither would a medical event which caused her to black out or lose her equilibrium.
