That story unfortunately is more common than you think. I work fire/ems where I live and we usually get 5-6 cases a year(small town unfortunately no rednecks but too many liberals) of something close to that. You would be surprised the stuff that goes on in your town that will never make the news. If you want interesting stories, buy your town firefighter/emt a beer and ask him about weird stuff in town or better yet if their volunteer join up(believe me they need the help) and see it for yourself!! Case in point.
We get dispatched for the man injured by the snow blower(Please remember if you need to clear a snow chute stop the blades or turn the machine off). We get there, follow the trail of shredded boot parts, foot pieces and blood to the kitchen. As we were wrapping the guy's stump. We tried talking to his wife who was sitting quietly in a wheelchair with a blanket over her lap. The husband told us not to bother and that she didn't talk!! By this time all of us noticed the smell of bad cheese in the room, but since we had more pressing issues dismissed it and loaded the husband in the ambulance bound for the hospital. We drop him off and get called back by the cop doing the report at the house. He tells us the wife isn't responding and if we could check her out. Fast forward to the end of the story. She hadn't been out of the wheelchair in a year,and that funny cheese smell was gangrene(for the younger folks-that's when your arms/legs start rotting away) on both her legs.
