Judging from the photo, unless she's been rode hard and put away wet a few times, I'd call BS just 'cause of this:
Witnesses say Ms Symons, aged in her 20s, was waist-deep in water when she was shot by the hunter, believed to be aiming at a low-flying bird.
How close would one have to be to get a tooth knocked out by bird shot? And if one were that close, I'd expect a bit more damage than she's showing.
