OHHH-- I hadn't thought of slavery...I know it is a big problem in some places, but how would they have gotten her off the island?
Well heck O'Reilly reported that the chaparones who were supposed to be watching the kids left the island in a private plane before the kids.
Not sure how they would have transported her or even if she has been transported off the island, but as I understand Natalee is not the first to come up missing around that area.
And to think about it the Aruba LE and higher ups attitudes gives off the vibes that they are not that concerned. They are more concerned about their tourism business.
