I've been meaning to post about this for ages!
I think I've described the tracks of NB's head gsw's accurately. So assuming these are correct I'm not sure about the location of the casings? The CoA doc, courtesy of MF, gauges the distance of these gsw's as:
64. In respect of the eight shots into Nevill Bamber's body, the six to his head and face were fired when the rifle was within a few inches of the skin.
I've uploaded a soc photo showing NB's found position and reposted the casing layout diagram. MF told the court casings travel forward, upwards and to the right up to about 4 feet.
Some of the text, whoever wrote it, on the middle photo is misleading. According to Vanezis, livor was consistent with the position in which Nevill was found, perched on a chair back with head in scuttle. So he couldn't have been sitting down as normal, then pushed over by the TFU when they entered the kitchen at 7:30am.
Casings as you know bounce, rebound and deflect anywhere. Those two on the kitchen floor might even have been kicked into their found position by the perp or the TFU, the third landing on the table by itself.
