I genuinely don't know the answer.
As far as I'm aware no one observed June with a black eye on 6th Aug. AE's WS states the following:
"On one part of his statement he told the police officers that Aunt June Bamber had black eye and when Jeremy had asked her to account for it she had apparently said, "I hit a post".
Jeremy told the officers that he thought that there was more to her injury but Aunt June Bamber was not going to tell him.
I formed the opinion that Jeremy was insinuating that Sheila had hit Aunt June Bamber. I asked the police officers if my Aunt June Bamber had a black eye but they couldn't tell me".

"...whilst the severe bruising to her left eye was caused either by a blow or the impact of gunshot".
CAL page 192:
"Nevill had other injuries besides gunshot wounds. The severe bruising to his eyes and a laceration to the right side of his nose were due to a blow from a fist or blunt object".
Is this the norm from a pathologist ie no firm idea about victims' injuries including the burn marks to NB's back?
