Thanks for all this info, Bruce. I have to admit I had ignored your site until now because I assumed there was nothing new being presented (nothing wrong with that if it had been the case btw). But, having looked at the detailed photos you posted there I think it's obvious that the rock was thrown from the outside, not the other way around. Also casts serious doubt on the "ransacking".
Having seen the photos on Bruce's site, here are the points that stand out:
1. The rock is indeed inside a bag. First time I've actually "seen" this. If AK and RS staged the break-in and threw the rock from the inside, seems like they would have gone out of their way to at least place the rock strategically at the opposite side of the room. Why would they either place or leave the rock in the bag?
2. Throwing the rock at the window from the inside: Seems highly dangerous. You would either have to stand right in front of the window pane and smash the glass while holding the rock, likely slicing up your own hand in the process... or you would have to stand away and launch it at the window pane, which with the window open would mean standing in between the window and the desk and throwing it - highly unlikely in such a cramped space. And even if you were to attempt it, you again risk exploding glass right in your face.
3. The glass shards lead from the window back to the front of the room in a trajectory logical to being broken from the outside. If broken from the inside the glass would be projected toward the wardrobe. You can argue that they moved the glass shards, but then they should have also moved the rock.
4. The photos do clearly show a messy room. The only items "disturbed" are Filomena's clothes. So, unless the perpetrators were trying to make it look like they broke in and tried on a bunch of her clothes, this looks like nothing more than a messy room (and incidentally, very similar to my own room right now, end of the week, when I haven't bothered to clean it yet).
