Just because he got a complete pass thru doesn't mean anything. He could have complety passed through the deers leg for all we know. What color was the blood? Did you find any blood up high on weeds, grass, trees etc? Find any spots where the deer bedded? Did you look around water?
The blood was well, red. It also looked just like dried blood?? No high spray, all the blood was on lthe groundand none on the trees that I could find. Didn't look to be lung blood. I checked all water sources and all blow downs.
