Not sure if the colour of the three burns to Nevill's back has been discussed before or not?
Anyway, I asked Grok about burns with a heated object and while there is little difference how quickly they form on a living or dead body the colour of them might indicate when they happened!
According to Grok, burns that occurr after death appear drier, paler and yellowish in colour.
But as we can see, the burns to Nevill's back appear to be dark purple, almost black!
Thing is, at the time of the trial it was just assumed that the burns had occurred before death, either by prodding, torture, or whatever, so there would have been no need really to question 'when' they happened, would there? And the colour certainly indicates pre-mortem burns, well according to Grok anyway!
So!! This will be another question for Professor Peter Vanezis and others!
In their professional opinions, judging by the colour of the three burns to Nevill's back, did they happen before or after death??
