Please tell us why,the suspense is killing me..and whilst you're about it tell us why nobody in that house heard a report of a rifle..
DCI Jones and other senior officers present at the scene gathered around the body of Sheila on the bedroom floor, pondering and discussing how Sheila had come to be shot a second time by use of the rifle that had been standing at the bedroom window, which had been picked up by a member of the training exercise involved in a reconstruction of the raid (which took place after 9am) and placed upon Sheila's body lengthways with the muzzle of its barrel in the region of the solitary wound (at that time) upon her throat. The rifle (Y) was resting flush on top of her nightdress as described (during the reconstruction) and the fingers of Sheila's right hand were positioned upon the trigger mechanism, and pressed against the trigger which discharged the second round under her chin, sending the fatal bullet (PV/20) thundering upwards through her chin, up into the void of her mouth, through the roof of her mouth until it became deposited in her brain. It was at this stage that police realized that Sheila had not been dead until the second shot had been discharged. By this stage of course, the police surgeon, Dr Craig, and all the ambulance crews had already left the scene. The member of the training exercise who took possession of the rifle from the bedroom window did not know that the rifle in question was still loaded with any ammunition because he mistakenly thought it was the gun which had been used to shoot the victims including Sheila herself and that another officer who was part of the original raid team had made it safe already. All of this took place before the arrival of DCI "Taff" Jones at the scene and before he actually entered the farmhouse, but other senior police officers such as DCI "George" Harris, were present...
When DCI "Taff" Jones went into the house and eventually ended up in the bedroom where Sheila had already been shot twice, a huge debate and discussion was already in progress between police officers who were present in the bedroom about how they were going to have to explain how Sheila came to be shot twice, when already she had been pronounced as dead (Dr Criag, at 8:44am) with a solitary wound to her throat? The rifle in question (Y) which had discharged the fatal bullet (PV/19) had been removed by the time DCI Jones arrived in the bedroom, and made safe by PI "Ivor" Montgomery who checked to see if the gun was still loaded with bullets, and that there was no further ammunition in the breach of the rifle? He also believed to have activated the safety switch on the weapon, before "Taff" Jones took possession of it and whilst others were gathered around Sheila's body on the floor, he relaid it atop her body with the muzzle of the rifle close in proximity to the two bullet entry wounds on her neck and by moving Sheila's right arm he was able to reconstruct what had taken place during the training exercise when one of the officers had accidentally shot Sheila under the chin and killed her?
Prior to the arrival of "Taff" Jones in the bedroom, Coroners officer, PC Wright entered the bedroom and viewed the body of Sheila on the bedroom floor with no rifle on her body. It is known that PC Wright did not enter the bedroom until about 9:25am, and so what this means is that once DCI "Taff" Jones arrived at the scene at a round 9:10am, he must have been engaged elsewhere at the scene for 15 to 20 minutes or so before he actually ended up in the bedroom carrying out the exercise described above at about 9:30am...
It was during this reconstruction when everyone was gathered around Sheila's body on the bedroom floor, that it was agreed that it could be suggested that Sheila had been shot twice by use of the same gun, through recoil because of the type of weapon which had actually fired the second fatal shot under the chin (by the police). When those present had finished discussing the pro's and con's of this, police proceeded to stage manage Sheila's body with the rifle (Y) in different positions, making sure that the safety catch on the rifle could not be seen during photographing...
