Your post is also full of assumptions. First we have no proof the silencer was found in
the cupboard etc, etc. So in truth there is no hard evidence either did it. It just depends how each persons interpretation. There are no hard facts. Even if somebody did put the silencer back in the box in the cupboard there's nothing to tell us it was Jeremy Bamber.
Erm, yes it was. This is what evidence was used in a court of law. Now if you say there is NO evidence YOU have the onus to prove otherwise. If you cannot then it stands.
That's the way the law works Maggie whether you like it or not.
Your second point is down to statistical plausibility. If Jeremy Bamber phoned the police to say that his father had phoned him, then that implies he had knowledge of something was wrong at the farm BEFORE the police did. Now if Sheila could not have put that silencer back in the cupboard - Jeremy Bamber certainly did.
In 1985 it was established that the blood found in the silencer was the same grouping as that of Sheila. It was argued that this was actually animal blood but this has been shown to be impossible due to the presence of a certain enzyme in its make up. The blood could have belonged to someone else but the question has to be asked as to how a strangers blood could find its way into a silencer which was purchased new and has only ever belonged to the Bamber family?
This aside, a breakthrough came with DNA testing in 2001 and just ahead of Bamber's 2002 appeal. The silencer was tested thoroughly with the baffles all being minutely tested. A sample of DNA was given by Sheila's birth mother who lives in Canada. Advances in forensic science methods led to the recovery of DNA from inside the sound moderator which returned 17 markers out of 20 as a match to Sheila which was substantially better than the maximum coincidence rate of thirteen. The DNA was found on the baffles deepest within the silencer. The chances of anyone else having the same DNA is some 100 million to 1. The chances of someone else having the same DNA who also had access to the silencer is billions to one. I must add that it was not determined by test if this DNA came from blood as the quantity was too small. However, given the results of the blood analysis in 1985 and the results of the DNA analysis done in 2001 it doesn't take much to realise that it was Sheila's blood found in the silencer.
It is almost certain that blood and DNA belonging to Sheila was found in the sound moderator.
In short Maggie, it WAS Sheila's blood inside the silencer. Now I will ask you a question; how did the silencer find it's way back into the cupboard if the person who's blood is inside the silencer is dead and found in a completely different area of the house? Sheila could not have shot herself with the sound moderator attached nor could she have returned it to the gun cupboard after shooting herself twice in the throat.
This, among other evidence was enough for me to conclude that Sheila did not murder her family. There is absolutely zero evidence that she murdered her family, there is no plausible method or believable scenario on how she murdered her family and no-one can prove she murdered her family. If this be the case, and there is no reasons to believe otherwise, then she has been maliciously maligned, shamefully castigated and her memory desecrated.
Now if Sheila did not murder her family - and I want you to consider the implications of that statement bearing in mind what I have just said -who in your mind did?
