Okay, I'm looking at the pictures from
this page and I am still going to maintain that Rudy could not have made his way across that room from the window without disturbing anything in his path or stepping on any of the glass. Filomena kind of makes it sounds like the floor is absolutely covered with her stuff, but there's quite a bit of bare space, albeit none without splinters of glass.
I don't know if anyone has ever suggested before that the inner shutter, when hit with the rock, could have banged into either the wall or the wardrobe, causing the flimsy, unlatched, particleboard upper wardrobe doors to fall open, adding to the "disastrous" look of the room.
ETA: Yes, Ron Hendry did mention that: "If the outer top shelf door at the wall had been left open by Filomena, then the action of the rock being thrown threw the window from the outside may have induced several articles of clothing to fall from the top shelves. When the large rock impacted the inner solid wood shutter, it would have induced a strong rotation of the shutter. This rotation may have slammed the inner wood shutter into a fully opened wardrobe door and this contact may have induced a strong twisting and jostling action of the wardrobe closet to the extent that many of the overstuffed clothing items fell to the floor. The several photos of the inner solid wood shutter and the top shelf door show varying positions between the two. One position we don’t see is the inner shutter swung around to the wall until it was well out of the way. The shutter’s position in the various photographs is always such that it could have been stopped by contact with the wardrobe door."
However, after reading the whole page, I am still not at all convinced Rudy came in through the window.
I think Filomena is a snake.
