Linked to this, could be the absence of any bloodstain on the bedroom carpet, beneath where Sheila's body was later photographed by the police, of a bloodstain found on the back or rear of the nightdress. How could such a bloodstain be present on the rear of Sheila's nightdress, and yet be absent from the carpet, beneath which her body was photographed to be laying upon?
It should be obvious to anybody, that by the time Sheila's body was moved from the bed to the bedroom carpet, the blood on the rear of her nightdress had already dried, so as not to stain the carpet beneath her body...
