The bag in the first photo is pictured almost exactly where Eddie alerts.
Also with regards to the time cadaver odour first starts to develop the times quoted on the previous page are averages. The decay process of vertebrates begins rapidly after death (i.e. "four minutes after death") [Vass, A.A. Understanding Human Decomposition] and leads to the release of postmortem compounds in the ecosystem . These cadaveric compounds, mainly volatile organic compounds (VOCs), are by- or end-products of the decay process. Using dogs it has been shown to be detectable as soon as 30 85 minutes after the time of death (Cadaver Scent Project)
For a possible time of death, IMO, we need to look at the period between the last independent sighting and 30-60 at least 85 minutes before the latest reported time that the alarm was raised (22:15). Another possibility would be to conclude that Eddie alerted to blood behind the sofa and not cadaver odour. In addition a body may have been concealed in the cupboard in 5A and removed some hours later. This last scenario (which seems unlikely due to the risk of detection) would rule out GM being the man Martin Smith saw carrying a child.
Another scenario that would explain Eddie's alerts only at locations directly associated with the McCann's would be that someone using the McCann's apartment or hire car or items of clothing has been in close proximity with a corpse and had introduced cross contamination. Is there any truth in the stories that KM tried to explain away the alerts by saying she had attended a number of post mortems and she had taken her daughter's favorite comfort toy with her!?
You mentioned the case of Shannon Matthews in one of your posts. This is what The Nat Policing Agency said in a review of the case which included the use of Victim Recovery Dogs:
"The properties that the dog searched contained a high level of second-hand furniture bought from dwellings where someone had died. This resulted in numerous indications that required further investigation to confirm whether they were connected to the investigation, or to previous owners of the furniture." 5A didn't belong to the McCann's. They simply rented if for 7 nights. How would anyone know the history of the place in terms of materials used in construction, construction workers, fixtures and fittings, furniture and human traffic any of which may have come into contact with a corpse directly or indirectly and then caused the dog to alert?
The only owner occupier in the block was Mrs Fenn situated directly above 5A. Prior to purchasing her apt at OC she lived elsewhere in Portugal with her husband who suffered Alzheimer's. Upon his demise she purchased the apt. Is it possible the dog alerts were connected to Mrs Fenn's apt?
Re the hire car were the control cars like for like ie hired or similar? If the control cars sustained far fewer drivers/passengers then there's less likelihood of them coming into contact directly or indirectly with a corpse. For all we know the hire car might have been rented by an undertaker. What checks if any were carried out on the cars to determine their history?
Afaik the substance thought to be blood as evidenced by the dog alert wasn't visible to the naked eye? LCN DNA tests were inconclusive. Therefore it seems to me if the substance was blood the potential sources are many and varied: people cut themselves shaving or on sharp implements, children have bangs and scrapes, women have periods, etc, etc.
I'm not a McCann supporter just looking at reasonable explanations for the alerts other than something sinister.
