Unless you're sure he never had plastic surgery to alter his nose a bit, that may not be a big deal. Plastic surgery on someones body can look considerably different after they're dead and there's no blood flow through the tissue.
Just tossin' in something I've seen that is maybe a bit of a caution on whether or not much can be judged from the available photo.
Your nose also looks different if some jacked convict punches you in the face.
Thanks! I learned something new!!
