Possum Story

I received this mystery picture in my inbox today. Why 'mystery' ? Because it came with no explanation.

It came from my father. I believe the foot and legs are my mom's.

So what's the story that goes with this picture? Anyone has any idea? Was she attacked by a possum and the camera was all they could find next to her body? Or maybe she bought this new pet because she thought a dog was too much trouble...?
