Bizarre!
I had something similar to this happen, but for I believe for different reasons. I downed a four point, he had a two point and a doe along with him. It was in a heavy wind and snow storm, I dropped the four point quick. The doe and two point didn't even flinch. As if they didn't hear the shot. The two point walked about 25 yrds. then came running back to the downed deer and kept locking horns and messing with him. I walked up to the downed deer and proceeded to dress him out, the two point and doe stuck around within 25Yrds watching me the whole time. never bothered them that I was there. This was quite a ways back in the pasayten.
