I wonder if the wife knew the head shot was coming, and whether she had full confidence in her husband. If so, I can imagine her leaning her head carefully in one direction, and winking at her husband for the "go ahead".
Glad it turned out okay.
There's a lot of information that is missing. For example, was the store owner REALLY aiming at the head? Or, was he aiming at center mass, but missed but ended up hitting the head?
I'm thinking the former, because (correct me if I'm wrong) judging from my own experience at the range (not in real life thankfully), people tend to miss "low" rather than miss "high" (?)
