Sheila Caffell could not have self inflicted the two bullet wounds in her neck because of the swing involving the rifle, from its set at the time of the first shot, and where it was set at the time of the second shot! Another way of approaching this subject would be to fathom out why the first shot did not end Sheila Caffell's life, a shot she fired across her neck rather than upward into her head? If recoil had occurred, how remarkable then then once the first shot gets inflicted that the gun should fall flat against her body and that the fatal shot should then get inflicted? It doesn't make sense ..
