Yes. A New York pathologist, an leading expert in gunshot injuries, exhamined the photographs of the two wounds to Sheila's neck.
Okay, so the long and short of it, is that the defence has obtained an expert opinion that the wounds to Sheila indicate that they were caused by being shot with the rifle without a silencer attached.
I recall in the past, you have said that if an expert acting for the prosecution gives a different opinion, to a defence instructed expert, then the defence expert should be given the benefit of doubt, although that hasn't been what has happened in this case in the past.
The CCRC have dismissed experts evidence in the past, indicating that they do not agree with their findings and methodology.
