I do think this is the same elephant in all of the pictures.
In the shot of the skinners taking the hide, you cam just see on the bottom side of the belly that the skin is already cut. This must have been taken after the upside was skinned and I suspect that they rolled it over with a truck or something to finish the job (is it possible to roll over a good sized elephant?)
Isn't it customary to allow the folks from the surrounding area to butcher the animal after the hunt if there are villages in the area?
