From what MotoMike said Russell also wasn't a foolish man and aware of the risk getting into a heated argument with a stranger in the middle of nowhere and said he can't see Russell doing that.
It didn't sound like he was the type of guy to grab a gun and start wrestling unless it was already a life or death situation so that can't see him doing it before Carol was shot unless there was serious reason.
GLs story isn't a bad one as far as CYA stories go but with what we've heard about Russell here it doesn't ring true.
I agree.
To start with, how did Russell know that GL had a shotgun. If he saw him carrying it around in the brief time he was there, that would be a strong reason not to have a violent argument with him.
If Russell had seen it, how did he know where it was kept in the Nissan Patrol.
In my mind I see GL approaching Russell's campsite carrying the gun, they had a heated verbal exchange near RH's tent followed by a fight and Russell tried to grab the the gun in case GL was going to use it. CC was standing near RH's vehicle as there was DNA on the roof of the Landcruiser.
If the knife belonged to GL, how was it that he was carrying 2 large weapons. Khukris (Ghurka knife) are heavy. I know because I bought one for my son who's a big camper, while I was in Nepal where they're used for cutting branches off trees etc.
If the blood on the hotel bathroom doormat was Russell's, it need not change GL's story that it was an accident because if you kill someone, whether it be murder or accident, blood is bound to splatter onto you.
Unless we get a confession, and IMO we won't, we will never know what really happened. There's a huge amount of circumstantial evidence and we just have to hope and pray that it's strong enough. We don't know much at all at the moment so it's an agonising waiting game for us.
