Hogzilla?
Remember this is a DUmmy. If the hog wasn't stolen, then it most likely died of natural causes (swine flu?), and was disposed of by giving it to the DUmmy. Animals that die of natural causes are not in much demand commercially! They also cause extra work and disposal expense. A DUmmy would be an excellent cheap method of disposal.
I had a friend who had to shoot a heifer that escaped into a swamp, and he could not catch. Had a lot of trouble trying to find someone to butcher the carcass because they feared it may have had died of some illness. They only wanted to butcher animals that came in on the hoof. I guess there is some health regulation about that.
