I don't doubt the story but the 2nd and 3rd photographs are not real. They show the fence abutting a red brick wall and chainlink fence...there is no red brick wall or chainlink fence in the 1st photo.
The spacing of the bars in the 2nd and 3rd photo are different from the spacing in the 1st photo.
How did the head wind up placed with the fence spike into the neck? A wound that did not yet exist until the decapitation took place. How does it wind up in that position? And why are the eyes closed?

Look carefully at the first photo with the body. You can see the chain link fence and red brick wall. With regards to the spacing of the palings on the Iron fence, the photos are from different angles thus making the spacing seem wider in the first photo. I see nothing to indicate that these are "fake" photos.

The chainlink fence is there. Look in the lower RH corner. The red wall is too far back to see.

That's due to parallax. Look at the first photograph on this page for a wider view of the scene. It may be staged (I don't think so), but even so, why would someone bother to stage it twice (resulting in inconsistent photographs)?
