In my opinion, if I was shot, I'd put my hand to the injured part of my body, therefore smearing blood onto my hands and onto any surfaces I touched. If Neville was shot 4 times upstairs, then went downstairs you'd think there would be at least some sort of a blood trail tracing his path. Same goes with Sheila moving from the kitchen, upstairs- there would surely be some sort of blood spatters on the floor from where she has been.
Too much talk of people moving about, wounded and bleeding with no real evidence (that I can see) to back it up. All seems like far fetched explanations
-----------------------------------------------------
Hang on a minute, lets get the fact right, (1) there is no blood trail from the main bedroom leading all the way downstairs to where Ralph Bambers body ended up, and so any suggestion that he was shot up to four times in the bedroom, cannot be seriously entertained. None of Ralph Bambers blood was found to be present at all inside the main bedroom, and so, as i say, or at least as I am trying to point out, I urge anyone who is remotely interested in the truth surrounding this feature of the case, to think long and hard and ask yourself if Ralph could have been shot up to four times in the bedroom and leave no microscopic trace of blood at all, anywhere in the bedroom, to suggest or to confirm that he had even been there in the bedroom at all, at the time the shootings started?
(2) as for Sheila having bled all the say upstairs, after, and if, she had been shot downstairs, beforehand - it is not true that there would necessarily be any blood spilled on the route taken by Sheila, if the wound had developed a clotted plug of dried blood which sealed the bullet wound entry hole. It would only take some 10 to 15 minutes or so, for the wound to the side of her neck to stop bleeding, and the entry hole to become sealed by a plug of clotted blood, and if that is what happened there would not be any blood pouring out all over the place, contaminating everything and anything in Sheila's wake, en route to the bedroom upstairs...
The smear of "O" type blood found on wallpaper on the main stairs, might not necessarily have been the blood from Ralph as everyone is assuming, since, the two child victims also had "O" type blood, and the bloodstained wall paper could just as easily have been blood from them...
