Man this will be a heck of a first post.
Mtn lions have home ranges that can encompass several HUNDRED square miles. There was a lion tagged with a radio telemetry collar in colorado I believe, wandered all over Kansas, and was finally hit by a car in Oklahoma. In a state that had said we had NO mtn lions prior to this. None had ever been recorded until then, or at least not in recent histroy. We now have mtn lions listed in our hunting regs. So is it so unusual that there might have been one in West Virginia? NO. Is it possible? Yes. Do I believe that is a lion kill? No.
The tracks are bobcat sized, not lion sized. Also, cats dnt "skin" the animals prior to eating. FWIW look at the nape of the neck, cats generally kill large game by either breaking the neck (in the case of a mountain lion), or by strangulation or bleeding out from the throat area (bobcat).
And to why there are no pictures... Have you tried posting a picture of an unusual and or large animal? People will jump all over you about it being photoshopped or whatever. I mean with the chupacabra/zombie/dogman trail cam pics that are circulating is it any wonder why some people might not want to post their pictures?
Another possible reason is that in many areas, if the animal is not listed in state regulations and you harvest one, that is breaking the law. So a great many could be killed each year and never reported due to this.
Just my $.02
