Mike, it's late, I'm knackered, but still I fight. Right. If Sheila killed her family on that night, she would have been covered in blood (especially Ralph's), her whole upper body would have shown signs of gun residue, her hands and nails would have been damaged, her feet would have been dirty and blood-stained, and the gun would have been PLASTERED in her prints. Stop the conspiracy theories. Look how she ended up, dragged into place, with her hair and nightdress pulled up behind her. How could she have placed the bible after she was dead?
