I haven't heard anything about Natalee emailing Sloot before going to Aruba. In fact, I would discount it because Sloot supposedly told authorities that while in the car, he and Natalee exchanged email addresses and then he was dropped off first, remember? That was back when his story differed from the two brothers.
I agree. I don't think that part was right.
It was the second, Diario/Venezuela part that was most intriguing to me. . .
"He told Wiggins that he knew one of the Kalpoe brothers because he went to the same Internet cafe, Wiggins said."
I wonder if the cops checked the computers at whatever internet cafe these guys went to. (I could have sworn I read that the one kalpoe brother was home online and emailed by joran at 6:30 that fateful morning.)
