The S&R dogs have a long history across the globe on all terrain which links into thread in terms of scenting the direction MM left 5A.
I think the point of
Search and
Rescue dogs is just that: they look and if they are successful they find.
I wonder why it took so long for anyone to show enough interest to take notes of their work until Rebelo was firmly ensconced in the co-ordinator's chair?
On the 7th of May, Rex and Zarus showed a great deal of interest in apartment 5J of the apartment block. In their desperation to locate the missing child the PJ seem to have omitted to search an empty apartment in the same block from which she had disappeared.
Therefore not only is there a feasibility of disposing of a small child's body in the immediate area there is the feasibility that she was transported within that timescale of six days after her disappearance to anywhere within six days travel from Luz that you may care to suggest.
May I remind members that no-one has yet come up with intelligence or proof that Madeleine McCann died in Luz if she is dead at all, let alone speculating on the feasibility of her burial there.
