Does anyone know how much they are investigating regarding the others who travelled with Natalee from AL?
No. And the chaperones haven't said a word.
All I know is that they have been questioned by the FBI.
The last people seen with Natalee was Joran, Deepak and Satish.
Joran keeps changing his version of the story of what happened that night after Natalee left the bar (and her friends) and got into Deepak's Car with Satish and Joran at about 1am Monday morning. (the big mystery is what happened after that.)
They have the right people in custody (minus probably the father who should also be arrested IMHO), now the truth has to come out and it is now a waiting game.
The police have blown a hole in the 3 boys story about them dropping Natalee off at the Holiday Inn at 2:00 or 2:15 am Monday morning.
The brother's say they dropped Joran and Natalee off near the Marriott, Joran later also said this was what happened. Now Joran is changing his story again but we don't know Joran's latest version is.
You mean like one those traveling with Natalee might have put her in their suitcase by accident?
