Probably already posted here somewhere, but this article talks about a possible link between Natalee and Amy Bradley, the girl missing from the cruise ship docked off Aruba in 1997. Also interesting and frightening possibilities here that chill me to the bone.
Excerp
"Late at night, Arubas California lighthouse could easily serve as a beacon to guide boats to the deserted beach to quickly drop off and pick up narcotics--but news show guests intimated for days that submissive females, possibly drugged by bartenders or other patrons at a popular club like Carlos and Charlies could be victims of sexual transport.
"Spotters," paid to watch for attractive women on vacation as potential sex slaves could guide them into a bar to be drugged and then out into a waiting car and boat for transportation to mainland or island bordellos."
I know, I know, consider the source, but in this case, It's totally plausible.
