I think it is possible they buried her-that said, T5’sguy is a detective-he believes that however she died, Natalee Holloway’s body was taken out in a boat, weighted and dumped into the ocean-he says that would be fast, convenient and the best way to make her disappear forever. He also believes Joran van der Sloot either had killed a woman before and was-or was on his way to being a serial killer-and I certainly agree with that...
Things in the ocean have a tendency to wash up. Tides, salt water buoyancy. You’d have to go our really far.
