By writing things in a certain order in her book Kate suggests to the reader they happened in that order, but they didn't. The twins weren't in the photos of 5A, so they had gone before the PJ left, although the impression is given that they were still there.
The PJ locked the apartment and left the GNR guarding it, so no-one was left in there. Emma Knight's evidence makes no mention of cots being placed in 5H.
It is possible, however that the twins were moved twice. Once to the new apartment, perhaps with Fiona staying with them, and then to 5H later after Emma left.
This fits with Jane Tanners evidence that Kate and the twins were gone from 5A at 3am when she spoke to the PJ, with Emma's that they went to the new apartment. and with Dianne's, that they arrived in 5H quite a while after they left 5A. It also explains why Gerry and Kate carried them out of 5A, but David and Fiona carried them into 5H, according to Dianne.
Eventually, at about 3am, I managed to get hold of Michelle’s partner, Jon Corner, on his mobile. ‘No one’s
listening!’ I wept. ‘Nothing’s happening!’ The next thing I knew, the PJ officers were heading for the front door.......And with that they were gone, leaving us to our own devices....We probably could have stayed in our apartment, but who would have wanted to? Looking back, it’s inexplicable, of course, that we should ever have
been left in what was now a crime scene....Mark Warner had prepared another flat for us on the first floor of an
adjacent block, but Gerry and I were in no condition to be on our own. We couldn’t look after ourselves,
let alone the twins. So the staff put up two extra cots in Fiona and David’s apartment and we carried a sleepy Sean and Amelie into their sitting room. [Madeleine]
A request was made to the OC services director for the family to be re-allocated and accordingly the babies were taken out of the room, so that the site could be searched.
http://www.mccannpjfiles.co.uk/PJ/VITOR_MARTINS.htmAt a certain time, after the arrival of the PJ elements, the parents removed the twins from the beds in which they were still sleeping and took them to the first floor flat. At the request of Kate she (the witness) to remove their puppets drink and a blanket that she took to the first floor flat. Only the mattresses remained.
http://www.mccannpjfiles.co.uk/PJ/SILVIA_BATISTA.htmI received a call from John informing me that he had arranged for another apartment for the McCanns. I went to reception and helped Lyndsey to move the two cots to the new apartment
The McCanns went to the new apartment and I remember seeing Kate and Mrs Payne seated on the sofa, each holding one of the twins. I left the new apartment at 04.30 in the morning after instructions from John Hill. I was the last to leave, the police had already left, but I left my number saying that I was available for anything that might be needed.
http://www.mccannpjfiles.co.uk/PJ/EMMA-LOUISE.htmI think Russell came with me and there was Sylvie who was the translator. I can’t remember which, there was some, there was a PJ chap was sitting on the, by the table. And there was Gerry who was standing by the, the bedroom door”.....“That was at three o’clock in the morning after she’d disappeared, yeah”
4078 “And where was Kate?”
I don’t know at that point, she wasn’t, she wasn’t in the, she wasn’t there. I don’t know whether, I think they had taken the twins out of the room by that stage, so I don’t know whether she was up in Dave and Fi’s room”.
http://www.mccannpjfiles.co.uk/PJ/JANE_TANNER_RIGATORY.htm”Yeah. So after the twins had been brought up did Fiona and Dave stay in the apartment with you?”
Reply ”Yeah well at that point Kate and Gerry came up as well and err because the Police had decided to close off the apartment, bit late in the day but you know, they came up and what we did we got the, there was mattresses on the spare beds in the room where Lily was sleeping so we got them and put them on the floor in the lounge beside the twins so that they could rest, if not sleep, err but by this time it must have been about half past four, five o’ clock in the morning.”
