I have no reason to disbelieve DCI Redwood ... nor do I have reason to distrust that the PJ could only reopen the case based on fresh evidence.
What is clear is that they're trying to find fresh evidence of the missing girl. They don't spend millions on a massive search operation unless they have fresh evidence to back it up. Amaral was doing the same before he was removed.
In a letter direct to GA from DCCB dated 27 September 2007 (Vol 11 p2945)
With regard to the possible sighting of arguido Gerry McCann next to a pink coloured block of apartments at a site opposite the Luz cemetery, we can inform you that this an establishment called 'St James Portuguesa Lda', lots 1 and 2 being situated in the positions mentioned, from the outside the spaces corresponding to Lot 1 can be seen of a total of apartment designated as follows: 101-104, 111-114, 121-124, 105-109, 115-119, 125-129.
As concerns the information provided by F***** J**** with regard to a sighting of the McCanns at a residence called Vila d'Arte, in the Melody Urbanisation in Espiche, during the month of July, it was possible to determine which residence this was and that the building is the permanent residence of some citizens from NL or the UK for the past 4 or 5 years.
The owner of the villa said that he had been in the villa after the departure of the McCanns and that it seemed to him that there were new plants at the bottom of the garden, without being able to indicate exactly which plants, a fact that he commented on with the gardener F**** Do S*****.
From the cleaner who worked in the residence occupied by the McCanns, it was found out that on the previous Monday 10-09-2007, she carried out her normal cleaning routine without noticing anything abnormal, just remarking that two or three boxes with dossiers were in the garage and which were later collected by a friend of the McCanns, Susan.
