I've lost track with this thread with the various digressions etc. Suffice to say, I don't think the parents 'did it', whatever that may be. They did take a risk I personally would never take in leaving my child in a hotel room on their own (& with doors or window unlocked - not sure which).
With regard to Newtonfox's comment above, I think I saw a newspaper headling that said the DNA is said to be the twins' DNA, not Maddies.
My main suspicions lie neither at the parents nor at the door of any 'international abductors' who have whisked her away to Spain, Morocco or anywhere else - but they lie with a local person or, slightly more likely, a holiday maker including one the McCanns' friends.
