Moo...there was a child..Darius..that went missing at an Alberta campground recently. He does have a WS thread. When the reality of his survival ended...so did the search.
There was not much info on family and he is probably in search area, but not found. But there was not the theory that the family was hiding something. Children do go missing, they are hard to find.
Searchers are adults, they do not see the world from the much shorter height of a child. Children do hid, and curl into fetal position when scared or hurt. Which complicates finding them....moo
