The only thing that would climb such a steep, rocky incline is a puma. Would a sneaker be found looking new? Possibly. Are there any studies on how long it takes a sneaker to age in the environment we are told it was found in?
IMO pedophiles simply do not deposit the bodies of their victims in nearly-inaccesible places. It SEEMS they do try to cover their crimes, but not in such difficult terrain. Predators, however, live there and do carry their food where they can eat it in peace or bring it to their offspring.
No parent wants to admit the death of their child, myself included. Yet, once that death is confirmed, what is the difference between an animal attack and a human attack? Either way the child is still dead. I do NOT understand why this case is being kept alive the way it is, except publicity of some sort? What? Any ideas, especially from our beloved Thunder Street, who hasn't really given any evidence of anything, IMO.
