Does the blood on her right forearm suggest her torso was in an upright position when she was shot, with blood dripping from the first wound?
Incredible how she is meant to have fired over 20 shots without breaking a nail or damaging her nail polish. And this is before shellac became a thing.
According to the 2002 appeal decision:
"Dr Vanezis gave evidence that the nature of the blood stains to the nightdress suggested that Sheila Caffell was sitting up when she received both injuries. After the second injury she would have immediately fallen back. There was no evidence of any other mark or injury to Sheila Caffell's body such as might be suffered during a fight or in a scuffle."
Unless we get very specific testimony we can't know whether the blood on the outside of her right arm was from when she was shot or after police lifted her and blood came leaking out of her mouth. Since she was up per the other evidence it could indeed have leaked down her arm though it also could be a wipe. I have seen blood wipe patterns that look exactly like the trails down her neck and arm. You wipe with the outside of your arm.We have no way to know how much time passed between both shots so she could have wiped before the second shot was delivered.
I saw so many people claiming she was fatally shot by the first bullet I took it at face value but not so says the opinion:
"The higher of the two wounds would have killed her almost instantaneously. The lower of the two would have been a fatal injury but not one where death would have occurred immediately and a person having suffered such an injury may have been able to stand up and walk around for a little time. The lack of heavy blood staining to Sheila Caffell's nightdress suggested that this had not happened here. The lower of the two injuries must have been the first since it had led to haemorrhaging inside the neck and this would not have occurred to the same extent if the other wound, which would have been immediately fatal, had preceded it."
As for not damaging her nails or and skin for that matter, it would require wearing protective clothing to give Nevill such a beat down, rapidly load the rounds and not to have any damage at all even as the stock broke. That event would in particular be likely to cause some damage. Julie said that Jeremy told her he wore gloves which naturally makes sense to do since he was planning to avoid liability. Unless she was also wearing shoes no way could she have wrestled with Nevill in that kitchen and had undamaged/clean feet.
For someone hell bent on murder/suicide wearing gloves and other protective clothing would not make much sense.
