No I don't think there was a HUGE kitchen fight .
There is nothing else in the room that indicates that?
Perhaps Neville stumbled around in his pain after being shot knocked over some furniture , blood on the floor , and then collapsed in the chair ? Then was attacked .
Or perhaps as ainsley said ( the man in charge) the raid team knocked some things over ?
We have no idea what happened earlier in the evening if it was Sheila ? They may have had an argument earlier in the night and Neville thought he had calmed her down ? She may have thrown the sugar bowl at him ?
Who knows?
I don't think there is anything that indicates who was responsible .
42. The examination of Nevill Bamber's body also revealed black eyes and a broken nose, linear bruising to the cheeks, lacerations to the head, linear type bruising to the right forearm, bruising to the left wrist and forearm and three circular burn type marks to the back. The linear marks were consistent with Mr Bamber having been struck with a long blunt object, possibly a gun.
----------------
Broken stock of rifle, damaged & removed watch, upturned chairs & stools, smashed ceiling light, spilled sugar, aga scratch marks. A man fighting for his & his families life after being shot. Nevill's head on top of a coal scuttle.
Not sure what else needs to be supplied.
