seth black and white
Apparently his version is they were in bed sleeping, he got up to go to the balcony to get some air, came back in and heard noises in the bathroom. The bathroom had an unsecured window so he thought someone was coming in through the window. He grabbed his gun, shot, and then realized she wasn't in the bed anymore and that it must have been her in the bathroom.

Still doesn't make sense, if his guns were in the bedroom and he went in there to get his guns, wouldn't he see she wasn't in bed at that time?
