I feel like Jug & Beth Twitty - I ABSOLUTELY believe that Paul Van der Sloot is involved in this crime. Let's not forget it was HE who called the little "meeting" at his pool side to instruct the boys WHAT story would be told to authorities. He also made the completely incriminating statement that "no body, no case"!! Why talk about a body if there isn't one??? He should STILL be in prison but he's part of what appears to be a massive screw followed by a massive cover up!! Thank God for the unrelenting pressure being applied to Aruba's Justice system and even it's politicians.
I think he's the one who covered up the 'accidental' or 'date rape' murder. PVDS is the reson the kids have not broken. He's assured them, they'll walk.
LOL - make that "screw up"!! I'm getting tired. *grin*
I think you are right. He is very much involved. His part may be hardest to prove forensically, but I am hopeful that it is not impossible.
