I'm still torn about what exactly was happening, I can see her reflection in one pic fairly clearly and I don't see any weapons, just the camera and her hand almost on the shower door.
In one (I don't recall the time stamp) it looks like the edge of something thin showing on one of the built-in shelves in the shower (the right side as we look at the pics) that I don't see in any of the other pictures. I have so many in the folder I'd have to search to find that one, but I'm just still not completely convinced of what happened before the last 3 pics were taken.
