Nevill just spending 2-3 seconds saying 'Sheila's gone crazy & she's got the gun', then putting the phone down & leaving it off the hook ?
That is surely the most implausible phone call ever.
Saying 'please come over' is at least asking Bamber to do something. Bamber choosing not to do it.
All the physical evidence at soc supports "Sheilas gone crazy shes got a gun":
- NB managed to call JB and say "Sheilas gone crazy she has got a gun" before he heard the sound of gunshot and left handset on kitchen worktop to run upstairs.
- June's head was resting on her pillow when she was first shot as per blood stains and Prof MacDonell's report.
- Between NB hearing the sound of first gunshot and sustaining his first gsw, June sustained 5 entry gunshot wounds and possibly a 6th graze wound.
- NB was then shot twice in the face as he approached the bedroom from the landing. He retreated and was then shot in the back of the shoulder with a further gsw grazing his elbow/chest
All the physical evidence at soc by way of blood stains or lack of, casings, distance of shots, trajectories and wound tracks support this.
