I thought it was Satish that got the email. Which would fit with my suggestion. Natalee would have still been with VDS and Deepak, priot to the email going out.
I also heard/read that both boys said they dropped VDS off with Natalee. I think that spot, somewhere a little ways from the motel, was searched as being where the two brothers left Joran and Nat. Has that story been debunked, too? There is so much to read on this thread and other sites.
So you think it could be that Satish left Deepak, Joran and Natalee. He went home. Joran emailed him saying "I have something to tell you..." And so he went (where?) and met his brother (who had Natalee?) and they both took her - or what??? So where did Joran go then?
Of course it is possible that something did happen to Natalee in the presence of Deepak and Joran, and Joran left while the other two "handled" it. But, would that explain why the supposed witness said they saw "two men (boys) forcing a woman into a car."? I mean, if something had happened to her or she were hurt/drunk/drugged, or something else, would she be being forced, or perhaps rather carried? I am not sure I am following how you are putting this together. Can you explain.
