I'm calling BS on the initial story.
To me wounds mean more than one. Nuff said on that (or at least the staff need to distinguish between wound and wounds).
2nd, shot in the forearm? How big is this guy that he can shoot himself in the forearm? Something ain't right in Denmark.
I had the faint tug of doubt when I read that, too, for the exact same reason. How the heck do you shoot yourself in the forearm with a rifle? I could see shooting yourself in the hand, maybe, or in the forearm with a pistol, but with a rifle? I agree, it sounds like something's not right in Denmark.
Also, three wounds? If the three wounds were on the same dude, I say no way was it an AD or ND. I assume that if you say three wounds, it's something like, through the hand (1), through the upper arm (2), and lodged in the chest (3). Something like that is possible if you get shot by someone else, but would be impossible to do to yourself, even if you tried. Oh, well, it's probably just an unintentionally-misleading article. I'm sure that those one-paragraph entries don't get much in the way of editorial review before the paper hits the newstand.
