I tried this last summer with the Nick Berg thing and it helped me keep everything straight in my head (a tough feat at times). It took a little work, but that was because once I started it, I sort of went overboard with it. Anyway, I was glad I'd done it by the time I finished. With the Natalee disappearance, all that is needed is for someone to break things out into categories, such as names, places, dates, or significant events, etc.
It's just a suggestion. I wish I had time to do it here, but quite honestly, I'm so lost now it's ridiculous. In fact, there's so much information on this, it may take more than 1 person to gather the information and put the pieces together.
Here's a link to the Nick Berg summary, in case anyone is interested. (I used FrontPage for the formatting, btw.)

You did great work on that Nick Berg thread.
I can do it (make it all pretty and in html), but I know that I cannot back up any of it because everything is hearsay (even through the media) and I would be called on it once again.
