Someone was still alive inside whf when Jeremy made his call to police from his cottage, provable by the fact that police who received the 3.26am call from Ralph Bamber, or whoever, were able to confirm that the call was being made from the scene. At that particular point in time (3.26am) the line between whf and the police was an open line in which Ralph provided the details which were contemporaneously recorded on the phone message log. Anyone else not privy to this call trying to make contact with the farmhouse by use of telephone would have been met by an engaged tone, which is precisely what Jeremy got when he tried to ring his father back at the scene. The matter of Ralphs call, and the separate call to the police by Jeremy were made to different recipients, at different times, 3.26am and 3.36am. To be specific, by the time Jeremy was making his own call to police at 3.36am, Ralph had already been in contact with the police (3.26am) and it may well be that Ralphs call had already ended or become terminated, so that when the recipient of Jeremy's call contacted PC West about the nature of Jeremys call, those details were recorded on the 3.26am phone log, "Message passed to CD by son"...
With this in mind, it can be shown that at 3.26am a phone call was made from the scene, and 10 minutes later another call was made by Jeremy from his cottage at Head Street, Goldhanger. The call made by Ralph to police at 3.26am must have lasted several minutes in order for the recipient of the call to record everything that got recorded, before mention of "message passed to CD by son" was added, which makes it impossible for Jeremy to have been at the farm, during the period of Ralphs call to police (3.26am to say 3.31am), and then be back at his cottage in Goldhanger in time to make his own call to police at 3.36am - this is the correct interpretation of what did occur, supported by phone records under power of the police and Special Branch...
If you take the time to think about the implications of what I have just said, somebody was still alive at whf whilst Jeremy was talking to police on the phone from his cottage. So either, someone who was the killer, or an accomplice was still alive at the scene, and all four victims already dead, or alive at that stage, or there was at least two of the victims still alive by that stage, Ralph and Sheila. Whichever way you look at it, Jeremy was not at the scene when he contacted the police at 3.36am, and it is even more relevant if you move the timing of Jeremy's call (by default) as having occurred at 3.26am, since it serves to establish to an even greater extent that Jeremy could not be in two places at the same time, and provide a different set of details that were recorded by two different recipients, in which the caller refrs to "my daughter has got hold of one of my guns", whereas the other recipient recorded, "Sheila has got the gun", or "She has got the gun", or "He has got the gun"...
If the contents of both phone logs were made as a result of the same call made by Jeremy from his cottage, how could two recipients make such fundamental mistakes in recording such simple and basic information?
The clocks were manipulated to help try and merge both calls into the same one, but it does not work unless the recipient of Ralphs call also made the same fundamental mistake of recording the time of Ralphs call 10 minutes later than it actually occurred (3.15am), in which case, you end up having to adequately explain all the contradictions and inconsistencies I have been speaking about...
