I was the founder of a pretty large urban deer control group in the 90's. We were hunting a golf subdivision...and our efforts were always to be "unseen" by any resident or golfer even if it meant not taking a shot at a deer if we felt it would cross in front of a golfer or go into someone's yard.
We had a guy and his buddy in the group- they were compounders- both passed the shooting proficiency test with flying colors- showed us photos of lots of dead deer. They shot cut on impact heads- as we would not allow expandables
One Saturday I get a call to come help this guy who had shot a forkie and lost the trail.
I asked the typical questions and got what sounded like the right answers....including the shot was right in the goodie box...I said "which side of the deer did you shoot into, and what was his reaction?" Broadside, on the deer's right, tight to the shoulder, and he bucked up and took off like a scalded dog- was the response. How long since the shot? 1 hr 15 minutes.
We went to where he'd marked the impact spot- i found 1 or 2 drops....and every 12 feet another drop or two- in a straight line- headed for a fairway. I followed onto the fairway, and found one small oak leaf in the middle of the open, neatly mown fairway that had a speck of blood on it- and I went straight across...and picked up the trail. 75 yards later- creeping along, I see the deer bedded on the edge of the fairway with his head up, very alert. He gets up and walks away from us.
I just happened to be hunting in that block of timber a lot- and knew the trails. I sent him and his cohort around in a big loop and told them exactly where to get on the two track that ran through the middle- that the deer would come across just toward me from them, at about 20 yards and he might be able to finish it.
I pushed it, watching it ahead of me, slowly so it wouldn't run, and saw the wound- it was in the lower RIGHT leg of the deer- not a fatal hit at all...just trickling drops of blood.
It crossed the road, and he pumped two more arrows into it to finish it. He was so excited about the kill I waited till the next day to fire him so he could enjoy the moment.
In several years, thankfully, we didn't have too many of those situations.
