People seem to think because she may have been sitting when receiving a shot, that she was awake.
Bamber had the freedom to move her into his chosen positions. The first shot because she was asleep. The second because she had already been shot. Bamber was also a lot stronger than her.
Adam she was not shot while asleep there is no blood on her bed and no blood in the room she was staying in what so ever.
For your version of events to be true Jeremy would have to not only have changed her bed sheets but to have replaced the carpet in the bedroom Shelia was sleeping in before he left the scene.
The blood on the carpet in the main bedroom is not consistent with a shot body being moved or dragged. Jeremy would then have to replace that carpet also then some how use residual blood to re simulate the event.
Its easy to say Jeremy could do this and could do that but your really under estimating what is required in order.
There is no evidence of Jeremy replacing sheets and its impossible for him to install new carpets after he killed everyone but before he returned home to call the police. This is utterly absurd or ridiculous
