Thanks for your advice Pathfinder but the case is too important to discard good information that is in the files.
So I post a theory of what that noise really was.
According to the files the witness guessed it might have been the sound of a child turning over in a cot.
That is possible, but here is another possibility, it may have been the sound of curtains briefly blowing in that bedroom, due to a sudden pressure adjustment when the witness opened the sliding lounge door.
Matt is the witness not Control Risk reports. If he heard any sound at all it would be in his rog.
4078 'Okay. We will move back then from that check. I am sure you would have already mentioned, but did you see anybody''
Reply 'No'.
00.45.51 4078 'Hear any cars''
Reply 'No. No, I mean, as I say, it was nearly always completely deserted, there was very few people in the resort, erm, you know, you only rarely saw, you know, occasionally people move about on the street and that was mostly during the day, erm, everybody else seemed to sort of eat earlier or, erm, used the baby sitting or whatever service, there were a few people about between and there wasn't really much of a thoroughfare for, erm, for traffic, so nothing that stuck out'.
4078 'In know specifically one of the Portuguese questions was, did you hear footsteps or car doors opening and shutting''
Reply 'No (inaudible)'.
4078 'Okay. And you attended the Tapas Bar. And what was happening there at that stage when you got back''
Reply 'Erm, well everybody, apart from Russell and I were back, so I arrived back before Russell, erm, I think I said, all quiet, or something to, erm, to, you know, Kate and Gerry and just sort of sat back down and we carried on and I told Jane that Evie had been sick and so later on when his food came, we said, he's going to be late, can we sort of send it back or you just keep it warm and he'll have it later on, erm, we had a conversation as normal, I just remember launching into this Jane relieving Russell'.
