I heard tonight on FOX that the guy from the Party Boat had a Dingy. They were talking about him being source to get rid of body.
This was just talk back and forth, not accusation.
Also, I believe others in her family had been to Aruba previously and just maybe, got acquainted with some ilanders.
Aruba LE certainly seem to have something they're using as evidence and emails would certainly fit in. It's also something that Natalee's parents might know, but aren't able to reveal at this time.
Her mom and step-dad didn't seem to have much trouble zeroing in on the van der Sloots within 3 hours after they arrived in Aruba after Natalee's reported disappearance.
Just conjuring FWIW.
According to the charts, anything tossed in the ocean would have come back to shore quickly.

How about if a weight was put on the body? The fish would have eaten by now. That's was Scott did to Lacy but then through time the body disintegrated and the torso got loose from the weighted end. How long will that take?
