I don't often read Rachael's statements so let's see if there is any indication Rachael was on hand.
Well I struggle a bit to get the picture of what she was doing, but by the sound of it she went to the patio door but didn't go in and then walked around to her apartment to check on Grace, started talking to Fiona and Jane. Rachael is uncertain about what Fiona does in some ways. For if Fiona came through the McCann's apartment early she would have passed by the raised shutter.
Looking at Fiona's rogatory statement:
"1578 'When you, when you rose from the Tapas table and you followed Kate'.
Reply 'Mmm'.
1578 'To their apartment 5A, you said that you didn't go into the apartment'.
Reply 'Yeah didn't go in'.
1578 'Who were you with at that point''
Reply 'Well we were altogether really, I think I was probably at the back with Matt, had some high heels on that I couldn't really run very fast, remember that'.
1578 'And then''
Reply 'I got to the bottom of the steps and Dave and Fi and Gerry and Kate were already sort of on the balcony of Gerry and Kates apartment, and I think had maybe already gone inside, erm and I think, I think Russell and Matt maybe went into the garden and just had a quick scoot around there to make sure'.
1578 'And then shortly after yourself and Matt''
Reply 'Yeah'.
1578 'Went round'.
Reply 'Went round'.
1578 'To your apartment''
Reply 'Yeah'.
1578 'How soon after'' "
As they walked around they didn't look to see if the shutters were up.!
"after we checked on Grace and come out and I think perhaps Kate and Fi were standing by the window, like on the outside of the apartment and no, Kate, I think Kate had said you know, somebodys taken her, cos the shutter was up and the window was open, erm yeah, I think it was then that we kind of realised that she'd been taken, erm as, you know, as opposed to just kind of wandering out of her bed and just wondering where people were, erm and then, and I remember then going to talk to Jane and Matt went off and that, I went to talk to Jane and said you know, that Madeleine had disappeared and the window was open and the shutter was up, erm and then Jane said to me that when she'd come back to do her check, erm she'd seen somebody carrying a child, walking kind of across the top of the T junction, as she, as she'd been walking up from the, from the Ocean Club, they'd been walking across the top of the road and we kind of said well you know, could have been, not could have been anyone but still sure it couldn't have been Madeleine because Gerry, cos you know if when she was, when she left the table to come up to do her check, Gerry was talking to Jez in the road,"
They (Jane and Rachael) heard Kate and Fiona discussing the open shutters and window, but presumably Gerry had lowered it by then.
So Rachael could be the person Amy Tierney saw provided it was before Rachael walked around to the car park side of the building.
What does Amy actually say about this?
http://www.mccannpjfiles.co.uk/PJ/RACHAEL-OLDFIELD-ROGATORY.htm "In reply to the question asked, she said that the back door (porta das traseiras) that leads to the parking area was closed, but she doesn't know whether the front door (porta da frente) was locked as when she arrived both the parents and a female friend of theirs whose name she does not know, were there and that is why the door was open."
It is possible this female friend was Fiona or Dianne, but I tend to think if was Dianne there would be a comment about the age gap. Jane is in her apartment and Rachael is making her way around to her apartment. Dianne is probably sitting in the Tapas waiting for everyone to come back. So what would have stopped Fiona seeing the window open and the shutters up?

'And your route, how far away from the McCANN's shutters, wall if you like, how far would you be away from it''
Reply
'Quite far away, erm, it's a distance, as I say, you've got a wall and then the car park and the road, so we were on the road, so it's, erm, I'm not very good with distances, I'd say, I don't know, around thirty metres, something like that'.

'Yeah'.
Reply
'Maybe longer'.

'Okay. So you then walked down the road, you bump into Matt, you turn right, you go in towards the Tapas''"
Well she didn't see them open as they went to the Tapas.
I'm not sure where Amy has her office but if it was near the Baby Club area this would have been an ideal time for Amy to become aware of the alarm.
"Reply
'Erm, tut, she sort of raced back
and she just appeared at the doors of the sort of reception area and just shouted across, erm, 'She's gone. Gerry, Madeleine's gone'."
So we all were sort of racing behind Kate and Gerry, erm, back up to the apartment. Erm, we didn't go in at that point, I think Kate, erm, Gerry must have rushed in with Kate and pretty much immediately Dave, erm, Matt, Russell and myself split up in four different directions just to do a search, you know, again assuming that she must have just wandered off. Erm, tut, so, you know, I don't know which way they went, but I, I went round the back of, erm, tut, well this way around the back of the apartments and round the back of the tennis courts on the main road and then cut down in front of the Baptista Supermarket and back up, that was the route I did'.
Really as I read this I tend to think it was Rachael who was near the door when Amy turned up as Fiona does quite a long search which would have taken the best part of 10 minutes to complete.
