It would be up to OG to follow this up. The armchair detectives just don't have enough information.
Everyone there is a potential suspect and if their statements change over time that becomes an inconsistency.
I would be inclined to think that the present investigation has progressed well beyond 2007 and early 2008. The information to hand in those early years was checked out by Scotland Yard investigators and those of the Policia Judiciaria independent of each other, each discovering gaps in the investigation.
Which is precisely what cold case reviews are set up to ascertain.
They interviewed those who had not been interviewed at the time and I am sure these interviews were cross referenced with existing ones.
I have no doubt that the present investigation centres on the here and now.
I am uneasy about any question being raised regarding any named individual. It is inappropriate and I think potentially libellous, for us who do not have the big picture of eleven years of police work to make anything of people whose only 'crime' was to be present in one capacity or another in Luz when Madeleine vanished.
