The blinds are parallel blinds so it's reasonable that someone could be unrecognizable and be seen and shot without damaging the blinds, if there were no damage. I can tell we definitely don't have all the evidence. We can't even be totally sure that is the window he came in through since the police also have other windows they took pics of. I would think it was that window because it is just a small step into the house. There was still dust on the outer sill. So he would have had to step through into the house. It's hard to tell how close the plants are to the window. It seems that there was no blood spatter so damage could be minimum to none outside the body. The EMS was able to check the body and remove the body without disturbing the plants, so they must not be very close to the window.
