Have been reading Jeremys updated blog.It is really interesting!
Under the section of Jeremys alibi,a PC Brown? also spotted the rifle in the window that morning.How could the rifle have been in the window and yet been found on Sheilas body when raid team entered if everybody in the house was dead?Also,I think it was Collins that stated he found Sheila with the rifle by her right side and not upon her body.
From what I can gather,the defence feel they have proved that Sheila was indeed alive in the farmhouse that morning,albeit maybe unconsious after administering the first shot to her neck?Nobody checked to see if she was still alive,presuming that she was dead.They believe that she made her way up one of the sets of stairs,took hold of the rifle and killed herself with second shot.In a statement,one of the officers admits that he heard a noise upstairs and shouted up the stairs to Sheila.
I presume the defence feel that the "cover up" concerns the fact that they bungled the raid by not checking if Sheila was dead or alive in the kitchen,which therefore allowed her to take her own life in their prescence.They could have possibly saved her life?Looking at all the evidence that we have been allowed to see,it is,in my opinion,an entirely plausable scenario.
