There is one thing i would like to add to my scenario.The burn marks on Nevs back .We are told three ring type burn marks appeared on his backon the night of the murders.So when was this done.Did JB decide when he was finished and ready to exit the house,that it was a good idea to heat some object up and waste time having some fun burning little ring like marks on his fathers back.Instead of scarpering as quick as possible and getting cleaned up.I have read the marks were made prodding Nev down stairs.If so when was the fifle heated in the aga,Was this before the massacre started ,or did he suddenly say ,hold on do you mind having a time out while i nip down srairs and heat the end of the rifle.Nev and June agree and say fair enough son.So JB nips down to the kitchen and while waiting for the rifle to heat up has a drink of water,its damned hot work carrying out a massacre in a wet suit.dosnt work does it.What about the story of checking if Nev was dead,when,after the big fight and he was beaten.Why bother,he was going to make damned sure everyone was dead with multiple head shots.Pointless.No i think there was more chance of Sheila inflicting the marks,and i will explain why in my Sheila scenario,to follow.
