Sorry to hear you lost this deer but as we all know stuff like this can happen.You say you hit the front shoulder blade.I once hit a deer the same way many years ago.That front shoulder blade is a tough area to hit,very hard to penetrate, and depending on the angle of the shot your arrow may not have penetrated the body cavity area.When it happened to me the deer was slightly angling away from me(only slightly)and when the arrow hit that tough shoulder blade bone it deflected and partially exited out.The deer then ran through the thick brush and a branch or tree caught the arrow and snapped it off about 8 inches back from the broadhead.I did find a blood trail but it ran out after about 200 yds.The deer probably lived but i'll never know.Just my guess.As for the meat,it wont last long in this type of temperature and if the deer does die and lay on the warm ground it will go bad fast.Sorry I cant give you more optimism but as I said this is only my guess.Good luck and I hope I'm wrong.
