The other relevant feature being that both wounds were/are contact, or close contact shots, where one of the bullets (PV/20) lost or had reduced velocity, with accompanying fragmentation, whilst the other (PV/19) did not..
Mike, please could you elaborate a little more on how you came to that conclusion, or where it is mentioned in a report?
Evidence exists which is in my possession to account for lost or reduced velocity and for why bullet PV20 fragmented, and why the other bullet (PV/19) did not...
Can you elaborate further as to what actual evidence? In my cynical world, it appears that this is just something to try and advance a theory that a ricochet occurred.
Basically as another expert has categorically stated that one shot was a contact shot and the other was from within three inches, I'm finding it extremely difficult to entertain the idea that you have solid concrete evidence that Malcolm Fletcher's findings are fabricated and you choose to publish this in the manner in which you have.
I think that if people really thought about it, the reason that one bullet was fragmented or badly damaged and the other wasn't, is for the same reasons that some of the bullets to other victims were fragmented/damaged and whole.
With regards to reduced velocity, the only sensible conclusion that I can arrive at is that you may also be trying to advance your theory that one of the shots was from a .22 air rifle, or perhaps a .22 bolt action Brno rifle with a damage barrel. If either of those is the case, then could we please see your evidence.
