Well if residue was not found on her then she could not have been shot. To have no residue on a person that has been shot at close range is almost unbelievable.
We went through this before.
For her to hug the rifle and shoot herself and not get any residue of any kind on her clothing and hands would be extremely hard to believe.
gunshot residue is expelled to the sides of the mechanism housing the firing pin. That is what sets off the primer and the primer is what forms the cloud of gunshot residue. The rifle, particulatly with the suppressor attached) is so long that even with the gun against the skin of a victim still could end up not depositing any gunshot residue. If the gun was not being held by someone else but instead held by the victim close to the body THEN in that case there should be gunshot residue all over the clothing of the victim, particularly the clothing near the firing meachanism of the gun but also the hand firing the gun. The other hand could potentially be far enough away to avoid it.
So the absense of gunshot residue is evidence she didn't shoot herself but rather someone held the gun horizontally at her. This explains why Nevill also didn't have gunshot residue. Even the close shot to his face featured the gun being held horizontally at him not vertically up and down against his body.
When hand guns are used at very close range they frequently deposit some gunshot residue on the victims because they are much closer to a victim than someone with a rifle. The longer the barrel of a weapon the further the shooter has to be and thus the greater the distance from where the primer is ignited.
She can't have changed an dwashed after being dead so this is a big problem.
Mike has come up with a rather elaborate scenario to get around all of this including the fact she didn't load any of the bullets.
He says June killed Nevill and the boys, she reloaded the gun, Sheila then killed June, she washed up and changed and police killed Sheila.
He has no evidence to establish it actually happened this way though. Saying it is possible doesn't mean it is probable.
