Vole, Shrew or Mutant?

Shawna and I have gotten some varying opinions on the possible genus and species of the unidentified mammal. Mutant, alien possessed mouse aside, the most prevailing answers seem to be a shrew or a vole.

I think I’m going to go with the shrew. I did a little research and it seems to be the most likely with the elongated snout and short tail. See picture below.

To me a vole looks just like a field mouse.

Now we could find out for sure by having Shawna count the toes, as the Shrew has 5 clawed toes (being a member of the mole family- thanks Wikipedia) and the Vole only has 4 (I feel so educated now, like the Steve Irwin of small rodent-like mammals - Crickey!), however the body has disappeared. I think another animal must have carried it away since she left the carcass on the deck, but she thinks it’s unlikely since it was wrapped in paper towels which are complete and undisturbed. Perhaps there is something to that mutant, alien possessed mouse theory after all.
