Just reading  the news items all again, see he fired shots through bathroom door. So there were bullet holes in the  door then I take it? They couldn't have been fired seperately I suppose? Still bl**dy good shots through a door though, consdiering where they hit the target 
 
Also I am damn sure in that situation I would have noticed, no matter how quickly I might have awoke or what time I had to reach for anything, if my partner was there beside me or not, not on returning to the bedroom.
