So it was OK that the dogs were alerting it seemed to 5J. Madeleine might have been in there?
Yet a days wait didn't / doesn't matter?
All the searches were carried out under the control of the GNR. The PJ asked them to use the dogs on 7th May to search the apartment blocks. They showed interest in 5A & 5J. I assume a report was then given to the PJ who then asked for the searches to be repeated on 10th May, but this time entering the apartments also. There are discrepancies in the GNR statements about when these searches were carried out, by the way. The dog handler says 8th May for the second search.
http://www.mccannpjfiles.co.uk/PJ/GNR_SNIFFER.htmIt is certain however, that the dog signalled next to apartments 5J, 5H, and 4G. He showed great interest in sniffing these doors and the immediate areas. Next to door 5H there were two bags of rubbish and the odour may have distracted the dog. Outside 4G was a tray of plates, cutlery and cloth napkins that had apparently been used. This apartment is where the parents of the missing child were staying (at the time). Concerning apartment 5J, the same may have been conditioned by the presence of people in the interior or he could have sniffed an odour that needed to be confirmed.
On the other hand, given the interest of the dog(s) in some of the apartment doorways, this could signify nothing, but could also very well mean that the dog has caught the odour.
The dog did not demonstrate to its owner that it had found the scent it was searching for.http://www.mccannfiles.com/id258.html
