I can see now that the residue which was on Sheila would have been minimal,,,as there were 3 guns in play,,,so no re-loading necessary. For starters,,the rifle that was lying on Sheila's chest wasn't the rifle that was seen on the window-sill,,nor was it the rifle that was downstairs,nor the one that fatally killed her.
One of those rifles was damaged,,,but not the one that was photographed with Sheila and it was devoid of paint marks. Only one rifle was identified even though the police knew that there had been more than one in use.
The bullet holes in Sheila's neck were made by two different rifles,,containing different bullets,,,as PV19 and PV20 bullets will only fit in their appropriate rifles and aren't interchangeable...There is a difference in thread. Both bullets in Sheila's neck were tested to be different,,,so I doubt that after Sheila shot herself once that she was going to " kindly ask Jeremy if he'd mind finishing her off ",but someone else did,,,and not by the rifle that's shown in her pics. That rifle fires PV20 bullets,,,it was a PV19 bullet that killed Sheila.
The police knew that it was a physical impossibility that the Anschutz rifle was solely responsible for all the murders at WHF but they went to court and swore under oath that one gun only had fired all 25 rounds.
