Stan Jones gave AE the keys to WHF after the police had finished. The relatives were not begging him for the keys so they could create a big frame.
If the relatives were looking to frame Jeremy, I am not sure why BW & Basil Cock were there. Bit risky.
Anyway they found the silencer in the gun cupboard. This is not surprising as Jeremy said he had (surprisingly) gone out to shoot rabbits without the silencer attached.
It was also surprising the silencer was off the rifle. AP said he had seen the rifle shortly beforehand with the silencer on. There is not much point in taking it off, if the rifle is used for shooting vermin. Didn't Jeremy incorrectly claim it was not possible to put the rifle in the gun cupboard with the silencer attached ?
Anyway one person found it, it seems while everyone else was scattered around WHF. Where are these big discrepancies in statements ?
