My head is spinning.....I don't know the timeline! Sounds to me that VDS was telling the boys this right away....but why? If the boys thought Natalee would just show up somewhere, why talk about a body? Why talk about her at all??
Now you're getting it! If they are now going to try to claim that they just thought she'd turn up and they lied to cover themselves (don't believe it), WHY would he say "No body, no crime."
