Chung Kim, 75, lived in Dallas next to neighbors he had been feuding with for years over something as ordinary as trash: dirty diapers and dog waste that, according to him, ended up being thrown onto his balcony.
In 2013, that dispute ended in the worst possible way. Kim shot them and killed them both. When the trial came, he pleaded not guilty and claimed he had acted in self-defense, but the jury heard his testimony and did not believe a word of it.
The sentence came more than a decade later: life in prison. Today, the case is cited as an example of how far a neighbor dispute can escalate when no one knows how to stop it in time. How many warning signs were ignored before it was too late?
