I've killed a couple, may even be forgetting some...
Remember shooting a nice buck myself once, deer was trotting across a clear-cut pretty far off, I took a quick shot and thought the deer acted hit. Never found any sign of a hit, but I was young back then and didn't really give a good effort. A week later some other guys were hunting in that area and killed a really good 9 point, it had a fresh hole all the way through the hindquarters. They said the deer was acting "funny".
I shot a buck with my bow once, straight on shot, arrow hit deer (I thought in the face / top of head) and deflected off to the side. About two weeks later during the special muzzleloader season I killed buck cross our powerline. Turned out to be the same deer, had a nasty gash from his mid-back to his tail right down the spine.
I posted another story about a 7pt I killed, and the taxidermist called me saying it had previously been shot in back of the head with what appeared to be a .22
Boy shot at a "big buck" at what he estimated to be 500+ yards late one evening in a field on our powerline. Swore he hit the deer. Way later in the season, actually the last day, I killed a 9pt in the same spot (I had climbed a power-pole on that same field, the deer was in the thick stuff about 50 yards off the field)....it's back leg was shot near the knee joint!
