Colin/Kathy
I think you are being slightly precious about my point of view, and my expression of it. I reiterate. Kathy constantly pleads that her only real interest is the missing child. The point I am making is that she never seems to add/start/refresh a thread that discusses her wherabouts or what we can do to recover her, but hastily adds to this one when there is anything smelly written, or done, involving the child's parents. Incongruous, methinks.
And Warbler. You are an intelligent man. When you breathlessy add that they are formally 'suspects' have the decency to add that this is a term in Portuguese law that only confers them more protection during police questioning. That poor soul, Murat, was once a suspect too for this Iberian version of the Keystone Kops.
So the scene was not preserved, the room was reused, there were subsequent forensic examinations and new the evidence is now applicable!?. I put it to you that in British jursiprudence, even if you lived in Birmingham or Guildford, that this circus would not be happneing.
Do I think the parents are involved? I havn't a clue, but am prepared to allow them innocence without inneundo until things are provan otherwise.
