I hate saying this because, but there is one important thing that we have to remember and to take into consideration and that is; that at this stage on the 7th August not one of EP thought it was NOT a murder suicide so to stage a body at this point would never convince a jury. Yes, her arm had been moved there is evidence to support that.
To suggest she was dead besides her mother with a rifle laying between them suggests the whole crimes scene was rearranged on that day and for that to happen would mean that nearly 30 officers or more knew about it and have stayed quiet for 28 years....Its hard to believe that this little secret would never come out and I don't think a jury of today would buy it....
There is no trace evidence to suggest that Sheila was ever on the bed, unless she was placed there after the crime scene photo's were taken by the funeral workers...this is possible, but why they would do that is not clear nor do we know that is what happened.
I think Its unlikely to have been staged at the point where it was deemed to be 4 murders and 1 suicide....but, anything is possible as we all know....
