At 7.15am, the anshuzt rifle was seen to be leaning against the bedroom window - if we are to believe that Sheila was already dead on the bedroom floor at this stage, how did the rifle end up at the window several feet from where her body was eventually photographed? Surely, if Sheila had already been dead at this time, the police could not have been fooled into thinking that she had committed suicide, since how did the rifle which had fired two bullets into her throat manage to manifest itself against the window? With the rifle against the window, at least one of the two bullet wounds which eventually ended up present in her neck could not yet have been inflicted, otherwise it was always going to be a case of five murders, and would never ever be considered to have been a case of four murders and a suicide. If the scene had been thus set, why would the police have any need to plant the rifle on top of her body at all?
Think...
With the rifle at the window, and Sheila's body on the bedroom floor at the same time, she could not possibly have committed suicide, and if she had already been shot twice, it would have been an open and shut case that she had been murdered...
