Police shot and killed Sheila after they took the rifle from the bedroom window (23) and placed it on her body - it was loaded at the time and due to mishandling and failing to check to make sure it was in a safe condition, a shot was discharged which effectively killed Sheila. They moved her body onto the floor and placed it on a rug from another part of the bedroom which had spots of June Bambers blood upon it. The bloodstain on the back of her nightdress was not duplicated on the rug beneath her body - they shot her, and killed her, and then they set about trying to cover up what they did. Part of the action they took was to create a false photographic record in the form of the MASTER COPY ALBUM into which they placed 223 of the 581 photographs they had taken, and from this they preselected 50 of those, and made them into another album, which they called the COURT ALBUM, which was to be given to the jury to help them make up their minds, as to Jeremy's guilt, or innocence? There were photographs in that COURT ALBUM which showed Sheila's body with the rifle atop it, which had been stage managed by the police, but the prosecution suggested that this was how Jeremy had left the body with a view to fooling the police into thinking, or accepting that Sheila took her own life (but she did not, and neither did Jeremy shoot and kill her), but it was the police who shot, and killed Sheila...
They cut up strips of photographic negatives to get rid of damning photographs in sequential order, which could be used at a later date by anyone who might come along to try and reconstruct what took place. Just like what they did with the bloodstained bedroom carpet, from that rather crucial area of the bedroom for where they had stage managed Sheila's body...
