the police admitted they moved her hand and the gun to photograph a blood stain.
They had no choice but to admit that.The photographs prove it.But they don't show the position in which she was originally found.Makes you wonder what else they tampered with 
Ewww.........Definitely am not thinking what you think I am thinking 
hmmm hope your not thinking what i think your thinking 
FUNNY!
On another note, her legs were very neatly aligned. She almost looks TOO neatly positioned after a gruesome killing or suicide - suicide more likely for this position in my opinion; but of course the killer might have placed her like that after the shooting for some reason (that wouldn´t point to a hired hitman, I think).
OR the police (and we KNOW the police moved at least the rifle and the hand). Perhaps she was in a too "indecent" position for the police to want to photograph her - who knows!
When I stumbled upon the photo of Sheila, I was really shocked - there was no warning, and I am not sure I would have wanted to see her face! It haunts me, really. She was very beautiful, so graceful even in death.
