There's never been a case like it. It's been over 40 years now that a Missouri town decided to kill a man described as a bully and no one ever got caught.
I've seen a zillion internet rankings of places and most of them are just opinions. In this case, I believe it might be provable by science. It's a Missouri town that has been declared the "creepiest" in America and there are a lot of very solid reasons why.
