Yeah, it was definitely a people thing. Squirrels, possums, woodchucks, etc. make a heck of a mess of things. And mice leave bite and chew marks on just about every one. And much of what a deer eats (like apples) falls back out of their mouth as they chew so there would be remnants of mashed scales all over the driveway. Sounds like this job was too clean to be any animal.
