The crawl space in CL wasn't actually searched, AFAIK, as the entrance to it had been blocked up for years and tiled over. However, the architect did send in the plans and the fact that the entrance was blocked was verified.
However, as we have both been trying to point out.... was any such verification done for Block 5 (or others nearby for that matter)?
Choosing to block up an entrance to a crawlspace in a private home may not equate to the same considerations in an apartment block.
Perhaps Alice has a view on this?
Possibly an irrelevance ... I have blocked the outside access to my cellar ... the entry I have retained from inside the house would be very difficult for someone who didn't know exactly where it is to find ... and unless one knew there was a void under the house no-one would be looking for it anyway.
It remains possible that there may be such a concealed entrance somewhere around the apartment in Praia da Luz.
I assumed that having located the entrance inside the villa, Carana, the police would have dropped down and physically inspected it.
I know that the architect had difficulty when he tried to pass on the information and the drawings. If memory serves me well, part of which was as a result of language difficulties when using the phone, but that is for another thread to discuss.
We have no idea what and where the dogs checked when they inspected ... the mind boggles if they weren't put into the space under the villa.
