Amy's statement is written so it is a fact but she could have been on the scene rather early. Even G-unit questioned why the woman in the creche said the missing child was called "Maddie" when the McCanns always called her Madeleine. John doesn't like it when I say there was an earlier incident, but the thought keeps coming that maybe the first incident involved "Maddie" but the creche workers guessed it was Madeleine McCann (as they admit) and so Amy actually went to the "wrong place" in fact but at a fortuitous time to see the 5A apartment as it was when Kate found it.
So Amy could have got there before the others had interfered with the shutters and the window. It seems unbelievable but I don't have a better explanation.
Was Amy the abductor? Maddy was called that by family and friends long before she went to Luz. Many examples. Gerry had Maddie written on his friends reunited page. They were shouting and searching for Maddy. Amy's statement doesn't fit. The tapas 9 were on the scene first not Amy.
"That on 3rd May at about 22.05 she was working at the Mini Club, at the "dinner time period" together with colleagues Charlotte and
Amy, when a female individual arrived, whose name she does not know, just that she was the mother of a child there (belonging to Toddlers 2), being a guest who was staying at the resort and who left at the end of the week, who told her that a girl called "Maddie" has disappeared, and that the girl's parents needed help in looking for her."
