And remember that only the McCanns entered their apartment via the patio door. Only they left the patio door unlocked and only their patio door would have been close enough to Mrs Fenn to be heard by her.
That is certainly true on May 3rd John. But we are not sure about other nights, are we? Mrs fenn heard crying on May 1st NOT May 3rd.
Had Mrs Fenn been sitting on her balcony, she might have heard one of several patio doors being closed ... and I think that her apartment went over Matts apartment too (one child) and was adjacent to the Paynes apartment (two children IIRC) so the crying could have come from any of them ... or even the flats above if tbey were occupied.
She was an old woman and her hearing might be deceptive. I am fairly deaf and I can no longer identify from which direction sound is travelling. Maybe Mrs Fenn was the same. We just dont know
Lets not jump to conclusions, cos there can be all sorts of reasons why patio doors are opened and closed. One example was on May 3rd when Russell let Matt out via his patio doors to go along the alleyway to the Mccanns apartment.
Even any Mum and Dad might have come into their apartment via the front door. Then Mum immediately gone over to comfort the child whilst Dad escaped the sound of the crying by going out via the patio door for a quiet fag / sit on the balcony.
And personally, with Madeleine not being a shrinking violet but an outgoing little girl, I think that has she been crying for any length of time, she would have got all three of them at it.
If we are not careful, we can hang, draw and quarter The Mccanns for things that have nothing to do with them
