that shot is ABOVE lungs and actually ABOVE the spine. hard to believe but i hit one same spot this year...hell you just told my story! 20yds..he ducked..bad penetration...half decint trail for about 400yds..dried up, searched the next day with 5 other guys combing the whole area to never be found. he never even slowed up. i lied..when he jumped a bunch of downed trees he slowed and blood came out better but other then that he never bedded or slowed. if he was dead we woulda found him im sure of it. and im almost posative i seen him once and my buddys jumped a buck that they described and it sounds like him turkey hunting. heres a link with some good info...

read all 5 pages and youll understand where i got my info..most people think theres a void above the lungs and below the spine..but at the vitals a deers spine is pretty danged low..guess because of the shoulders there and the muscle. if i was a betting man id bet that was the buck you hit!
