Hi Andrea 
Yes I do. I think 1 adult with a loaded firearm v 2 adults unarmed will have the upper hand despite the physique and gender of those involved.
June and Nevill were both so badly injured in the bedroom that they were incapable of putting up any sort of defence imo. Many of NB's injuries eg bruising were as a result of gunshot wounds. As I understand it a gunshot wound doesn't just leave a neat wound it causes damage and bruising to the surrounding area. The pathologist states that other than gunshot wounds he sustained injuries to his head and arm. These wounds could easily be applied once poor NB was dead or nearly dead and slumped in the chair.
It seems likely that the rifle rained down on NB and it could be that the stock detached then when it either hit NB or just about anything that was in its path if it was waved about.
JB didn't have any marks on him either. As we know JM continued to sleep with JB for a month or so after the murders so surely as part of her testimony she would have said if he had any marks on his body? He had no visible marks to his face or hands either. Of course if JB he might have worn protection eg balaclava, glasses and gloves. As I said I think anyone could have carried out the murders and walked away physically unscathed: 1 adult with a loaded firearm v 2 adults unarmed.
If SC I believe she showered, possibly washing her hair, and changing her clothes. Prof Knight at trial spoke about going about mundane task eg cleaning up afterwards. Sad case here where a father murdered his wife and two sons. He then took his own life but between the murders and suicide he spent the next 24 hours in the family home even washing the car.

Your agenda is to assert JB is innocent even though the evidence says otherwise and you intentionally distort in order to advance your agenda.
JB wasn't tested by police for gunshot residue. Nor was he thoroughly examined on the day of the murders or ever. One witness claimed he saw abrasions on Jeremy but it was not followed up throughly and they had time to heal anyway. Jeremy also could have used gloves. Under these conditions you have no basis at all to claim Jeremy definitely was evidence free. Moreover, if anyone would wash up it would be Jeremy since he survived and left the scene. You are intentionally distorting in claiming he was definitely wound free and evidence free on the night of the murders. The fact he wasn't tested means it can't be proved either way whether he was or wasn't.
Sheila didn't have the opportunity for her wounds to heal before her body was examined. Nor would a person in a crazy rage determined to killself after killing her family have any reason to wear gloves to protect her hands from wounds and evidence nor would she have an opportunity to dispose of the gloves so they would not be discovered. Nor would she have a motive to take a bath to wash away evidence and to change her clothes so she would have no evidence on her or to put the suppressor away. Only a killer in full control of his/her faculties who had no intention of killing himself/herself and didn't want anyone to find out he/she was involved in the murders would wear gloves, wash up afterwards and change their clothing.
Bullets can't have caused the injuries on Nevill's arm they were defensive wounds. A bullet to the jaw that goes down to the throat not up to the brain doesn't break a nose. The killer delivered these wounds and the wounds to Nevill's head by punching and bludgeoning him. Your claim that Holly would beat a lifeless body makes no sense. At any rate his arm was clearly blocking the blows he was not passed out. Severely beating a lifeless body woudl still result in broken nails and abrasions to the hands anyway. Someone grasping a rifle tightly to bash a body with it is going to break long nails as it strikes. Moreover you are ignoring the evidence of the scuffle- things broken, knocked over and the scratches from the silencer which were not linear scratches but zigzaged as they fought over the rifle.
If Nevill were so weak he never would have made it to the kitchen at all. In the meantime the 4 wounds delivered to Nevill were NOT severe enough to make him pass out unless he bled for a very long time. A couple of minutes would not be long enough to make him simply pass out. Only the final shots in the kitchen were severe enough. If Nevill had been injured so severely he quickly passed out he could not have dialed the phone as Jeremy asserted. In fact he can't have spoken due to his wound.
You can't have your cake and eat it too. Either Nevill was strong enough to dial the phone upon entering the kitchen and to defend himself or not strong enough to do either. The defensive wounds that you want to pretend were caused by bullets were in fact caused by blows and indicate he did defend himself.
The best way to embarrass you is to present the version you keep putting forth which makes no sense, is contradicted by the evidence, if patently absurd on its face and is made up by you PURELY to come up with a way to suggest Sheila could be the killer. Instead of following the evidence you made up nonsense.
Holly's narrative of the murders:
Jeremy visited the house and left the murder weapon, sans suppressor, on the kitchen table with a loaded magazine next to it. June and Nevill left the gun on the table despite the kids being around and set the table for breakfast around the rifle. Sheila was calm at around 9PM but by 3AM had became agitated and had a psychotic episode while everyone was sleeping. She had not taken any narcotics that would bring this on her medication simply stopped working suddenly. Sheila went downstairs and found the rifle on the table. She loaded it and then went in the closet and got the suppressor and attached it. Sheila then went upstairs and woke up her parents screaming at them. Instead of trying to disarm Sheila before she could shoot anyone, Nevill calls Jeremy to ask him to come help disarm her. Despite the fact Nevill was 6'4" versus Sheila at 5'7", had almost 100 pounds on her and was in good health he called to ask Jeremy to come disarm her, risking the chance of her shooting him and the others before Jeremy could arrive instead of disarming her himself.
Either the phone had been in the bedroom when he made this call and after the murders Sheila relocated it to the kitchen and took the receiver off the hook so the dead victims could not answer the phone if someone called or in the alternative Sheila had moved the phone to the kitchen earlier that day so that it could not be used by the victims because Sheila knew she would have a murderous psychotic episode that night and after Sheila threatened them Nevill went downstairs and made the call but she knocked the phone out of his hands and ordered him back upstairs to his bedroom and he complied without trying to disarm her.
Once they were back in the master bedroom Sheila then proceeded to shoot June and Nevill. Nevill ran back downstairs to the kitchen again and she followed. He collapsed in the kitchen even though the medical examiner said it would take a long time before he would pass out. She shot him in the head killing him then flung the rifle around a his lifeless body. Instead of holding it tightly and striking with it in that manner which would break her nails, she flung it repeatedly at him then went and picked it up and flung it some more and this is how the stock broke.
Then she went back upstairs and finished off June and killed her kids. Next she took the suppressor off and went downstairs and put it back in the closet so no one woudl know she used it in the commission of the crime. Then she took a shower to wash off all the evidence she had fired a weapon and committed the murders. Then changed into a fresh nightgown because the one she wore during the murders had gunshot residue on it and possibly blood. Somehow she disposed of it without anyone ever finding it only her panties that she had soaking because she menstruated in them. Instead of putting on new panties she goes without because she was still on her period and didn't want to ruin another pair even though she was going to then kill herself. Even though she heard Nevill call Jeremy she somehow knew Jeremy would not come over right away or call police right away so she had plenty of time to shower up and change. After making herself fully clean and presentable she killed herself.
I think I explained the folly in this narrative sufficiently that I don't need to take it apart again point by point. Instead I will let Peter Sellers respond to you:
