There was not blood from 3 different people. One person's blood made Keela alert.
"Thus, the Renault Scenic vehicle was moved to parking level -3 and subjected to an expert examination by officers from the Police Science Laboratory and another canine inspection that began at 03h49 on 7 August 2007 by the dog Keela, that detects traces of human blood, it having been verified the following result:
03h53 - the dog 'marked' an area of the lower right-hand side of the interior part of the baggage compartment of the car;"

Number 10

What do you think that was, PF? To me, it sounds like the CRL/10(1)) (the fibre-covered panel with ventilation vents). Which is what I found that she pointed her nose at.
Where I'm still confused is that this CRL/10(1)) thing had a plastic extension, which the FSS designated as CRL/10(2))
Is that (2) bit an attached (non-visible) plastic bit on the vertical panel, but without fibre-covering? Or is the attached plastic bit actually the horizontal bit designated in the PJ photos as No. 11? If so, the photo doesn't seem as if it's attached (unless there was some kind of fastening intended to keep them together and separated for shipping).
If the horizontal bit is (2), then there never was an absorbent mat.
The description of No. 11 (PJ) just says "tampa da mala" which I believe just means boot cover.

Ahhh. No. (It's been ages since I went through this).
No. 10 (2) doesn't seem to be horizontal flooring:

Then... PJ:
9. Head hair collected from the vehicle luggage area.
10. Parts of the vehicle luggage area.
11. Fibres and possible head hair in the rear shelf/luggage cover.
http://www.mccannpjfiles.co.uk/P12/12_VOLUME_XIIa_Page_3240.jpgSo No 11 (PJ) was where the forensic guys located hairs / fibres for analysis.
If that's the case, then there never was an absorbent mat.
