I wish you had a dollar too then maybe you could have a real shotgun abolt.
We may never know the truth about what happened since there is only one living witness but altercations between armed individuals leading to someone getting shot is kinda par for the course. Is it not? I am guessing someone pointed a shotgun at someone or did something stupid maybe shot at him from the blind or something... and it sounds like the old man was the better shot. He got 2 in what appears to be a 3 vs 1 shootout.
We will see where the body was found and what the autopsy says.
I'm not buying the dementia angle myself.
No government employees were harmed in the making of this mess.
