The Facts: I was mowing my backyard this weekend and came across a bloody leg. Confused, I looked around and saw nothing. Then, as I got to the other side of the yard, I came across fly-swarmed intestines. I continued my search to find a hand in the middle of both these discoveries. And in the far corner of the yard, what I had been waiting for, a rabbit head. The Mystery: A. Our fence and backyard are completely enclosed, so that animals can not enter. B. The rabbit parts were strewn about the yard. How did this happen?
