> 400,000 children are lost without a trace in the USA each year My personal fav source: https://www.canammissing.com/missing_411.html People have been trying to get to the bottom of this for decades - most of the missing (correction that not all are kids) are off of state and national park lands, which led to a ton of stupid conspiracies about shapeshifting creatures, bigfoot, and aliens. I've only ever seen one man possibly get close, by suggesting it was teams of men using hidden tunnels on these properties to get around and abduct people.
