Once Sheila's body was moved from the bed to the floor, a police officer wiped away most of the vertical blood flow which had previously leaked out of the lower non fatal entry wound, to give the impression that both wounds had been inflicted close together in real time. They were able to attempt this because blood which had run, and poured and leaked from the upper entry wound had left a duplicated trail close to the lower entry wound which gave an impression that both wounds had been inflicted at the same time? This was a deception that was shallow in presentation, but police got away with it because they withheld a large number of photographs...
A key feature which helps to establish this was / is the trail of blood which originally ran out of Sheila's left nostril, and then ran backwards into her left eye socket. The direction of blood flow present was not duplicated in the flow of blood from either side of her mouth, thus proving that Sheila originally was only bleeding from her nose, which ran backwards into her left eye socket as a result of her being lifted and carried off the bed and placed on the bedroom floor? At this stage, her head fell backwards which in turn caused the blood from her nose to flow under the force of gravity into her eye socket. If she had been bleeding from the corners of her mouth by this time, that too would have run in t me direction as blood from her nostril
