His. This happened in Colorado to a buddy of mine. A father and son shot a cow and it ran to where my buddy jumped it up from its bed and he shot and killed it. Well the father and son saw my buddy when he was walking out and asked if he saw a cow that was shot. He told them he just shot a cow that was shot before and was going back to get help. The father said it was theirs and after a little argument and being outnumbered two to one with rifles and handguns he let them have it. He was pretty upset though.
