That's interesting Harry. Two shots made in a " downward " position. Meaning : That Neville would have been on the floor ( on his knees ?) with the shooter standing over him-------so it had to be a pretty tall person ( Sheila ) to accommodate the length of the rifle as well. Nobody argues with a shooter.!
It wouldn't be the first time that a pathologist has been in cahoots with the police ! Ian Tomlinson's case was testament to that.
I admit that I suspect something of the kind happened. The police may have asked Craig to help them suppress the fact that Sheila died later than the others, to conceal some error of judgement on their part. What he said just doesn't ring true. People with medical training can normally give an opinion on time of death even if it's only an approximation.
As for Vanezis, he did not perform his autopsy on Sheila till the day after. By that time any indications of a later time of death for Sheila such as the lack of rigor mortis, as seen from how her right arm was moved by the police would have been lost.
It's notable that Vanezis has never commented on the crime scene photographs which allegedly show Sheila died later.
As for Bamber's defence, they were just not smart enough to get a second opinion on such issues from independent experts.
