You then admit they only tested what amounted to be part of June's blood trail around the bed not the entire rug. This explains why they didn't find Nevill's blood in the bedroom since they only ended up testing part of the trail going from June's side of the bed to the other side- which was a trail from June. This is a far cry from what you claimed of there being extensive testing without a drop of Nevill's blood found. Extensive testing didn't occur.
You are again trotting out your ridiculous made up claim that DRH/1-4 were not shell casings but rather things seized from Julie's house and these 4 things were moved so that 4 shell casings could be added. The initial day they ONLY inspected WHF and quite clearly the first 4 exhibits bagged and tagged by police would be from WHF not other locations. So on top of not having evidence to back up your claims your claim makes zero sense and is clearly false.
You are obviously deluded because the facts are that not one drop of Ralph Bambers blood was found anywhere in the main bedroom, you are creating evidence in the dark recesses of your mind, the only person making things up is you...
There is there was no expiated blood anywhere in the bedroom from Ralph Bamber, non on the upstairs landing between the bedroom door and the top of the main stairs, non on the main stairs, non on the main hallway floor or walls, non in the entrance to the main kitchen, non on the kitchen worktop near the bloodied finger marks on the edge of the kitchen worktop, non on the telephone, not on the kitchen floor - I guess he travelled all the way from the bedroom with a mouthful of bullets and blood, holding his breath all the while, and then collapsed in the kitchen, because he ran out of breath and suffocated, and became an easy target for Sheila to finish him off...
The true facts are that the suggestion that Ralph had been shot four times whilst in the bedroom was a ploy adopted by the prosecution to try and undermine Jeremy's account about receiving a distress call from his father. They asserted that with a mouthful of bullet that Ralph would not have been able to speak to anybody on the phone, hence why PI Bob Miller arranged for four additional cartridge cases to be added to the batch of crime scene ammunition associated with the main bedroom. There is evidential documents to support what I am saying, unlike yourself who relies upon absurd speculation...
