I've seen the pictures and video and it does appear legitimate except for one thing. Supposedly he was eaten Sunday night and cut loose yesterday. If that timeline is accurate I would have expected more digestion. Other than that, which is just an assumption of mine, I think this case is authentic. The python was also smaller than I expected too. Pretty crazy stuff.
With it being such a large prey item for the snake could there be problems with digesting the body which is why they found him how they did?
