I wonder if they will get DNA from Papa VDS.
Hey...didn't think of that! If he's still a 'suspect' seems like they would. Maybe they did and he went to the hospital before or after the other 3.
They have something that has DNA on it - it could be anything - semen from inside the car (possibly mixed with Natalee's DNA if she was raped in the car) - It is possible that the condoms or even the panties they found (and they have found more than just one pair of panties) may be Natalee's or have natalee's DNA on them as well as someone elses DNA and they have to figure out who's DNA it is.
Wouldn't it be interesting (and awful) if they did find something of Natalee's and they found DNA from all 4 of them on it? (if so this surely would not fit in with the Kalpoe story that they left them on the beach)
Transfer DNA from Natalee and someone else could have been found in the back of one of the VDS cars.
Maybe they found an empty drink bottle or can with a trace of Roofies and someone's DNA on the can.
It looks like they are trying to build a case against all or one of these boys because they have something that no one in the public eye knows about yet.
