I recently had a similar occurrence, I took my girlfriend out to hunt for the afternoon when out comes a very nice buck at 110 yards. She shoots and after tracking the buck for a few hundred yards the trail went cold and i lost the blood. Me and my friend looked all night and my dad joined me the next day, we eventually found it because i heard birds screeching it had made it over the fence to the next property. A phone call to the neighbors let me go get him, he turned out to be a nice 9 pointer i haven't measured him yet but he is probably a 140 or so and his cape was still good so my girlfriend can get it mounted. But I felt pretty bad though and we did lose the meat.
