IMO the mother, and then a minute or two later the father, as per statements.
No independent witnesses to confirm that is the case. Blind faith is dangerous and you won't solve any case with that naive unrealistic approach. People lie to save their ass so face it! Others were in their apartment straight after the alarm but only Kate and Gerry saw the open window and raised shutters. Dianne Webster didn't. If you went inside you would want to see the open window &%+((£ Why are they tampering and destroying possible evidence straight away instead of calling the cops?
David Payne can never give a straight answer &%+((£

Did Kate say anything about the window and the shutter''
Reply "
Err I'm sure she did but what she exactly said and you know because we were, you know, the first thing you're trying to do is work out how it could be opened you know, what was, you know, err and you know the discussion whether it be open from the inside or the outside but what she said I can't remember. But also on the back of subsequent discussions that we had about what may have happened, it's difficult to say without, or you know things merge into one.'
