Something else of significance occurred much earlier at the scene when PS Bews, PC Myall, and Jeremy went on a recce' of the farmhouse...
It was as a result of this 'event' occurring, which may have attracted the silhouetted figure to come and stand next to the parents bedroom window, as if peering out into the grounds at the front of the farmhouse! After a couple of minutes, the silhouetted figure walked swiftly across the full opening of the bedroom window, from right to left (as viewed from the vantage point, of Bews, Myall and Jeremy), going in the general direction of an internal doorway which led from the main bedroom into the box room...
With the benefit of hindsight, it now seems almost certain that the silhouetted figure had left the main bedroom and gone to the window in the box room which was situated on a different side of the farmhouse. It would have provided the silhouetted figure with an ideal opportunity to cast a lengthy gaze over the courtyard, near the back door to the house, as well as afford a general view toward the barns and outbuildings!
What was it, which caused this activity in the mind of the silhouetted figure?
Well...
It was the dog barking, which was locked away in one of the outbuildings, the sound of the dog barking alerted the person, whoever it was, that there was someone or something milling around outside!
Jeremy would comment to the two police officers at the time, that it was strange that his father (Neville Bamber) had not responded to the barking of the dog, because apparently it would have drawn Neville from his bed to investigate! Maybe, Neville Bamber was already dead by that stage (4.02am)? If so, then who could the silhouetted figure seen at the parents bedroom window have been?
June Bamber?
Sheila Caffell?
The Assassin?
Everything now known about by Essex police in connection with this matter leads to the inevitable conclusion that the person seen could only have been a reference to Sheila Caffell!
Remember, that when PC West had asked the operator to check the line to whf, how the operator had confirmed that the phone at the scene was 'off the hook', but that a dog could be heard to be barking? Well, maybe that was not 'Crispy' the shih Tzu dog that was barking alone inside the farmhouse, in all probability that was Sheila Mimicking a dogs bark in response to the dogs at the scene barking, both inside the farmhouse, and outside inside one of the sheds! When one of the dogs had started barking, or both of them, Sheila had took up the guantlet and started barking back at that dog, or both of the dogs!
It must have felt somewhat amusing to her, after she had attacked and killed everyone that whenever she barked, firstly 'Crispy' barked back in response, and this set off a chain reaction, whereby the other dog locked away in an outbuilding also appeared to join in on que!
Sheila must have convinced herself that she could communicate in this way with both dogs!
Hence...
Why, thereafter, she refused to use the Queen's English when communicating or in a conversation with the police who eventually turned up! She decided that she would only communicate with the police by barking like a dog, she believed that by taking this approach that she was conveying her responses to not just the police, but also to both dogs!
