Maybe he later said the window was open as he thought about various "intruder" scenarios to tell LE. Of course, we don't know if the window was in fact open, do we? He may have opened it, called in FW to show him (because as I recall, in PMPT, he called FW over to the window and said "Look, this is broken, I broke it last summer when I was locked out". ) It may never have been open till that moment. Colorado Decembers get fairly cold, I think. BR played down there, there was a laundry area, storage, and all those Christmas decorations that were taken up for the Christmas house tour. I can't believe they's have let a window stay broken all that time with the cold and draft.
