I doubt there is any. Were her fingerprints on the gun and, if so, were they in the right orientation to conduct such a shot. TWICE?
There was just one of Sheila’s fingerprints on the rifle, which Jeremy made by pressing her finger against it after she was dead.
Had Sheila fired 3 cartridges the rifle would have been covered in her prints.
All her long manicured fingernails were in perfect condition and even the ballistic specialist who tested the gun afterwards split one of his fingernails when changing the cartridges.
Nor was there any gun residue on Sheila’s hands, body or clothes.
Nor was there any blood from the other victims on her. She had not one tiny speckle of Nevill’s blood on her, and he was bleeding profusely when he beaten to a pulp.
She had no blood, sugar or glass on her feet or any of her footwear which she’d have bound to have had if she fought Nevill in the kitchen.
Her hair was examined too, and there was no traces of blood, gun residue or human tissue in her hair, either. Some members of Jeremy’s campaign try to explain that away by saying she carried out “ritual bathing”, but that’s nonsense. Her hair was dry and tests showed it hadn’t been washed and dried that evening. She also had a Tampax inserted as she was menstruating, and the amount of menstrual blood on it suggested she’d had it inserted for several hours: women never bath with a Tampax inserted. They remove it and put a new one in after drying themselves.
She’d gone to bed wearing her blue nightdress; the one she was killed in, and it had none of her own blood down the front, which proves she could not have walked downstairs after supposedly shooting herself the first time, to place the silencer at the back of the cupboard. The police searched the whole house, including the washing machine etc to see if there were any bloodied clothes of hers, and they found none.
Also, her arms were too short for her to have reached the trigger to shoot herself.
I’ve tried to be as quick as possible highlighting just some of the facts that prove Sheila could not and did not shoot her family or herself, but there’s also stacks of other compelling evidence which proves Sheila didn’t kill anyone — it was Ueremy who killed them, and he did it alone.
