Is it really more common for people to get lost out in the woods and stay lost - without a trace, no belonging found, no remains found (while there was a big search for them and people relatively quickly learned that person got lost in the area) - than to became a victims of foul play? Animals don't care about leaving evidence behind, scavengers don't care about anything. It's one thing to be out in the wilderness alone and get lost, while significant amount of time passes before people realize that someone is missing and they don't have a good idea where and when they were before they got lost. Different story when people are relatively nearby, notice that disappearance quite quickly - of course, there is still an insane amount of risk of not finding that person safe and well (especially with wilder areas), but not finding anything, ever? I'm not saying that's impossible. We all know that it is. I'm saying that foul play isn't unlikely nor significantly less likely cause of such disappearance. There are many monsters out there and Big Foot ain't one of them.
