Whodunnit?

So Gerry and Kate McCann are going home to England, after being named as suspects in the disappearance of their 4 year old daughter, Madeleine. This story has gotten huge press since day one. Celebrities have given millions of dollars to the cause. Supposedly, this couple left Madeleine, along with her twin siblings, alone in a hotel across the street from where they were eating dinner. They went frequently to check on them. They've stayed in Portugal to find her, till now.

Now they want to go home. To what? Hire a lawyer? Get out of the public eye all of a sudden?

Here's the thing: police found traces of Madeleine's blood in the couple's car. My first thought was, "So what? The kid had a nosebleed/scrape and got blood on the car. Doesn't mean her parents murdered her." But I guess it was found months after her disappearance. But can that mean that the police just overlooked it the first time? Are they being framed? Or did the parents do something to her?

Usually in cases like this, I think the father did it. It's always the father. But for some reason, I don't think they did it. I mean, they have gone through a lot to publicize this case. If they did do it, my god, are they working hard to cover their tracks. So who did it? What happened? I don't know, this is a tough one. Looks like another JonBenet Ramsey, unfortunately.
