You've listed 6 points there, and NOT even 1 proof there is any link to MADELEINE'S DISAPPEARANCE.
Now as to denial........................
How do you know Madeleine did not die in the apartment ?
If you intend to burgle a property or kidnap a child it is a good idea to familiarise yourself with the comings and goings around the property you wish to enter.
To that end an observation post can be quite a handy thing from which to 'case the joint'.
It was reported that a holidaymaker made the police aware of cigarette butts on the balcony immediately opposite apartment 5a.
He later told the press, "Those butts could have provided the breakthrough in the case, but I couldn't get the police to listen to me,"
http://www.courier.co.uk/Mayfield-director-s-Madeleine-McCann-evidence/story-17002971-detail/story.htmlWho knows the significance of these discarded cigarette ends, could have been something, could have been nothing. Nobody bothered to check if there was DNA on them which could have helped the inquiry at some stage into Madeleine McCann’s disappearance: is it any wonder there was no evidence pointing to anything in her case, if there was a culture of ignoring the obvious.
-SNIPPED - On the day of our departure we had to move out of our apartment and Mark Warner gave us another to use during the day until we left.
It was across the road from the McCann's apartment and the public balcony overlooked the side of their building and the road. You could actually see the front and back of the building from that view point. I noticed on the balcony that there was a pile of cigarette butts as if there had been someone stood there for some time smoking. I thought that was odd , and it could have been someone watching the McCann's apartment to monitor their comings and goings.
