According to the story the witnesses placed him at the scene
“as the shooter” and spent casings found at the scene were linked to another killing he was convicted of. If the defense ‘had anything’ they would have brought it up at trial I would think.
The lower courts upheld the conviction. That some witnesses
suddenly go wobbly doesn’t make the verdict invalid I hope.
The casings would tie the shooting to the gun he used in the earlier shooting. I am not sure how they would tie the shooting to the person who pulled the trigger. If for hypothetical’s sake the fellow who reportedly boasted of the killing was the culprit, he would have had to use Davis’s gun, which would raise the question of how he got it. Did Davis give it to him? Did he steal it from Davis? What would be the reason for either one? Occam’s Razor would suggest Davis hung on to his gun and used it again.
It’s not just “some witnesses,” it’s 7 of the 9 whose testimony convicted him.
Looking at the entire story...at the very least, he at least knows who pulled the trigger, if it wasn’t him....which you’d think that he’d want to point fingers, but never does. So I’m not buying this story of his.
