I would not be surprised if they have DUMB surveillance with trained abductors. All it would take is one well placed blow dart laced with instant night night drugs and make them drop where they were standing. The one man mentioned it looked like the clothing was crumpled in the place where the person had been standing. Like someone perhaps stripped them in place and removed them directly from the forest. I'm just conjecturing....but this has fascinated me over the years as well....and why I NEVER allowed my child to just "run around" our campsites...or even ride their bike around the camp ground alone.
