If you actually thought it through instead of jumping to an impossible conclusion, The sequence of events would be Shelia runs out of ammunition in one rifle, then gets another rifle from the cupboard before she kills herself. Its rather easy to work out.
Last week some said they hope I will stop lurking and post more. People like you are why I don't bother. When people post you rudely attack them. In this topic you just accused people of jumping to impossible conclusions and living in denial.
There was only a single rifle at the farm. The other firearms were shotguns. That single rifle was use to fire all bullets that injured the victims. The shotguns were not used. Your suggestion of Sheila using another rifle is what is an impossible conclusion under the circumstances.
You did the same thing when you suggested people were living in denial for ignoring that WPS Jeapes saw the murder weapon in the window of the bedroom. Countless times it has been discussed here that WPS Jeapes was looking in the window of the boxroom not the bedroom window. Her statement at most establishes she was something that looked like a rifle barrel in the boxroom window. Instead of being rude to people perhaps you would be better served by considering the actual facts. It is an impossibility that WPS Jeapes saw the murder weapon or anything else in the bedroom window given she was not in a position to even see the bedroom window and was referring to the boxroom window.
All I can say to those here who have the patience to challenge rude supporters who post the same false claims ad nauseam, is you are amazing chaps.
