update: we now know that his internal injuries were such he never had a chance. Since his wife got to interact with him before he passed, I figure this knowledge will help relieve her of those thoughts anybody in that situation has; that is.. could I have done something better?
Heck.. even though I was sound asleep at the time, I just keep thinking.. what if I had been out walking the dog?.. would my marginal knowledge of first aid have made any difference? (silly, i know) At least if the answer is no, that thought can't torture the mind as much.
Also, I'm told the body looks relatively uninjured outwardly. I guess that's something...
