There are many unanswered questions, and I have some myself.
Why were the employees at the tapas bar so sure of the McCann partys comings and goings when they should have been busy, busy, busy? Are they that interested in ALL their patrons movements? If so, why so? Something bothers me about this "resort" thing. Was there a possible kidnaping gone bad? The McCanns seemed to be rather well-to-do. Ransom would not be out of the question - neither would the burglaries we have heard about in the area, especially if someone is keeping a good "eye" on the intended victims.
From whence came the sample of Maddies DNA? Did it come from a hair brush; toe-nail clippings; an old blanket she had bled on? Im very curious about this.
Maddies blood in the trunk of the car could have come from the same source they got the DNA from, a blood-stained blanket, or some such. I believe the only way there could have been fresh/liquid blood was from a transport of the actual body or part(s) thereof. WHO rented and/or had ACCESS to that car prior (or during) the McCanns rental thereof is VITAL.
In the same vein, a cadaver dog can only hit on a cadaver, they cannot tell you the dead bodys name. I believe its within the realm of possibility that theres been more than one death around that resort and/or the rental cars - although maybe not little children with well-off parents. Aruba and a few cruise ship mysteries should have taught us "stuff" happens.
I believe Kate McCann said "cuddle cat" SMELLED like Maddie. Now theres a scary thought for you, if the cadaver dogs "hit" on it.
A tiny body could be cut up and put in the freezer of a common refrigerator, if the butcher knew what they were doing. Did LE check the frig?
I dont know the truth of this story, but these are some of the questions I would like an answer to.
