I'd have to have more than the shoe print, but we know that there was an SKS listed under GW4's name, on JW's wish list Even though, it's not putting him at the site, and is not proof positive he was there. Combined with that though, if I had to go by what I know so far, CN's testimony would tip me over the edge if I had to make a call, this moment, based on what we've seen so far. He's known him longer than anyone, with the exception of his brother and parents, and I'd say that he knows him better, on a personal level. His entire testimony showed that GW4 was physically capable of grunt work, and, that he was an excellent shot. Skilled at hunting, and patient. Willing to sit in a tree, and wait for a deer to come by, if it took all day. If it wasn't the right deer, willing to wait for the the right deer. I think he's the only one out of the four who could stand on their own, but he may very well have been the only one with the intelligence and patience for parts of this. JM2
Edit: Not to mention, he'd not wish to share a space with G4 again. CN knows in his heart. He just wants a jury to say so. Again, jm2
