A document also in the files states that when MO checked at 9.35 the stairgate may have been open.
SY will no doubt have tried to clear up these issues which the PJ failed to clarify when memories were much fresher. At no point does MO seem to have been formally asked the relevant positions of the side gate, the safety gate & the patio door upon entering & after exiting 5a.
If the safety gate was unlocked when KM did her check - it may not have registered in her mind, or she may have no recollection at all because of the shock almost immediately afterwards.
Yes same document Misty and it was written by the T9 themselves.
I sometimes wonder if any of the 5 SIOs who were or are on this case looked at small important details like the make and model the stairgate was or know how it works, how to lock it, how to unlock it. The instruction book is clear - closed does not equal locked. And if it wasn't locked it would provide no obstacle at all to a child.
Why would anyone bother locking it anyway if they were so sure a child wouldn't wake and wander?
