Kate says completely open; wider than when Matt saw it.
She noticed that the door to her children's bedroom was completely open

"At around 10pm, the interviewee went to check on the children. She went into the apartment by the side door, which was closed but not locked, as she said before. She noticed that the door to her children's bedroom was completely open, the window was also open, the shutters raised and the curtains open, while she was certain of having closed them all as she always did."
OK problems with translation and understanding come into that. She says the door was closed to begin with. But a closed door in my understanding is latched but later it was defined as 5 degrees open. How open is completely open?
To me "completely open" means it can't be any more open, but we'll never know what was meant in the interview with Kate on the 4th.
When is a window open? I've just reviewed TTOL and GA makes the point that Kate says the window was completely open, but we've just seen she says the door was "completely open" and the window was just "open" (no degree of openness expressed).
