" Has it been confirmed that Joran was actually at the casino when Natalee's family arrived at the house? Maybe he was right at home in his apartment, and his father wanted to give him some time to get his act together (literally). ""
I have not heard of any confirmation of Joran actually being at the Casino when Natalee's family arrived at the house, either. You bring up an excellent point, that he may have been at the house during the time they went to the Casino to look for him. As I recall from Greta's interview with Jug - Greta asked Jug how Juran got home from the casino and Jug responded by saying he did NOT know.
Later the whole group went to the Holiday Inn. Juran was said to have been at the Windham Casion earlier, which may have not been true, like you pointed out.
Deepak mentioned this in one of his messages posted on Scaredmonkeys and someone posted it on this thread yesterday.
