What we have to be able to understand in a situation such as this is in a hot climate with the apartment being closed down, the scent will build up in a particular area. If there isn't a scent source in here, i.e. a physical article where the scent is emitting from, any scent residue will collect in a particular place due to the air movement of the flat, the apartment and what I would say in this case is that there is enough scent in that area there for him to give me a bark indication but the source may not be in that cupboard, the source may well be in this room somewhere else but the air is actually pushing into that corner. But strong indication and I would say its positive for things that he is trained to find, which will be part of a separate debrief.
From what he says here I think it is irrefutable that Martin Grime was under the impression that the crime scene had been locked down after Madeleine's disappearance.
I doubt he would have used that description of scent pooling had he known that business as usual had been allowed and that various families had occupied it since Madeleine went missing. Ruling out Grime's appraisal of the hot climate in combination with
the closed down apartment would allow the scent to remain undisturbed ... hence the dog alert.
It is an entirely different scenario from families living daily in the apartment. Coming and going ~ opening doors ~ opening windows ~ cooking ~ eating takeaways ~ cleaning schedules while occupied and deep clean schedules between occupations.
Making it impossible to determine what exactly it was that excited the excitable dog into barking.
SnipThe blunder was revealed in the extensive 30,000 page police dossier into the investigation.
Details of all those who stayed in 5A after the McCanns were disclosed in an internal document written by Chief Inspector Vitor Matos to Goncalo Amaral, who was then leading the investigation.
- After the disappearance apartment 5 A was occupied by the following individuals: 12-06-2007 - 19-06-2007 by R and F. F****** (friends of the owners), from 28-06-2007 - 12-07-2007 by SR, W & CF, 12-07-2007 to 19-07-2007 by BSP and JFP, 19-07-2007 - 26-07-07 by MMS family.

https://www.telegraph.co.uk/news/newstopics/madeleinemccann/2523523/Madeleine-McCann-Apartment-was-not-made-crime-scene-for-two-months.htmlIt is highly probable that Martin Grime had no idea of these occupancies since it seems the McCanns were made arguidos prior to the judicial police locating evidence which justified it as the dates from the files would indicate.
