Everything is falling into place now - this why they are hot on this lead because it fits into something he told LE and he knows that area well.
Not to down play the Kalpoes guilt once again. But maybe Joran still did this by himself. The brothers may have came and picked him up and that is why they were seen there in the car together at the Racquet Ball Club, this was the pick-up point. They could have been planning the story up at this point in the car and Joran may have reminded them that Natalee was last seen getting into the Kalpoe car. I think Joran was smart enough to fool these 2 brothers into thinking that the brothers would never be believed since Joran's father is a judge (everyone on the island thought he was going to be a judge and word was not out yet that he failed his finals)
So Joran is muddy (explains the loss of the shoes) and he gets this mud in Deepaks car and that is why the late night car washing (the mud). Not sure why he let Joran drive but maybe Joran was cool headed and Deepak was not. Deepak seems to be easily spooked and Joran does not. Another thing is wash the car at a car wash and spray Joran legs off also.
Where was the car washing seen at? I figured at a drive up and spray car wash... but was he seen at his home cleaning up the car?
Why would JvdS drive?
Being a member he knew his way to and from, and around the racquet club.
So where did Joran get the tools for digging,,I don't believe he could have gotten them and done the deed alone.
That reminds me of something Jossy said tonight on I think Greta, that the spot where the car with the 3 was seen is more of a pick-up point.
