What a handsome guy. Though, I keep noticing in these photos that he is lighter in coloring than Jacques Doe. Ron appears to have had dirty blond or light brunet hair (probably was downright blond in the summer months), and light-colored eyes as well as a relatively light complexion. His facial features and bone structure are different; the way his chin and cheekbones are positioned and the size of his forehead betray that this is probably not the same man... Just my thoughts...
** Also, I don't really find that old postmortem sketch to be very accurate, when you look at the actual photos. I thought Carl K's recon was quite a bit more accurate to what he may have looked like in everyday life. It looks a little goofy because it's an illustration done using computer software, but I think this is the closest thing we have to an idea, some sense, of how the guy looked. Note the very prominent eyebrows and face shape.
