There was a recent interview with the founder of EquusSearch, Ted Miller who said that when they digging through the landfill, that Dompig from the Aruban police took Ted and Dave Holloway to a huge warehouse, all alone, away from all cameras and told them that Joran terrorized his entire family, that he ruled them all, they were all scared of him, and that Dompig advised them to stop searching the landfill for Natalee, that Joran was a sociopath who'd obviously murdered her and hidden her body far far far away in the ocean.
Personally, I think that there wer Human Traffickers who picked her up off the island and disappeared her into the sex slave trade in South America.
