One of the strangest parts of this story, IMO, is that none of her girlfriends or classmates have come forward to say anything to the media. Usually, there are a few kids who want to get on t.v. Evidently they've been asked to stay quiet while the investigation is going on and they're doing their part by staying silent. But I wouldn't necessarily believe some of her friends were in the restroom with her.
Based on the "good girl" reputation Natalee had, I definitely think that Dutch kid used a ruse to get her into the car. Plus, she'd been around him for a couple of days and probably felt like she knew him. He probably bragged about his dad being a magistrate on the island, etc.
They interviewed about 3 of Natalee's friend girls that was on the trip last weekend. One of them sounded so clueless, that she started making me ill. I had to pause and contemplate whether or not I was that naive when I was their age. I don't think that I was. I would not have been so optimistic that my friend would be returning under the existing circumstances.
