I don't think anyone is saying Crabtree is the killer. We are saying the scenario could not have gone down as he is saying. I am not taking away from the fact 2 men are dead and most likely Volwell shot them but it did not happen as he claims. JMO.if you are hinting that the survivor is the killer...then where is the old man?
..he brought help .. its not like he was the killer and he killed 3 and then he hid a body and made up a story .
