Hopefully from your time living there.
For me, during my junior high/high school years, a couple of the middle class kids started a fake suburban gang to bully the immigrant and poor kids in the town. One of those kids got fed up with with the bullying and shot/killed his primary bully from that gang during one of the summers.
Small town, so as I understand it, only people my age know the real reason as to why he shot the bully. The rest of the town just labeled it senseless gun violence between kids without any context. It's also my understanding that the fake gang pressured and persuaded people that knew to keep the cause of the tragedy quiet.
Kid ended up getting a life sentence. That fake gang rebranded themselves as a fashion collective and sponsor youth sports and events in the town as a silent act of penance for the pain and heartache they created. Nobody knows if the victims parents know why he was killed other than the people who were part of the problem.
EDIT: I've gotten some DMs about the situation so I'll answer the most popular ones:
The reason the fake suburban gang was able to keep the situation a secret was because they were the "popular" kids in school. Their girlfriends and girl-friends associated with them worked their way through the school body to peer pressure everyone into staying hush about it. Also, this was one of those schools where the amount of kids "in the know" wasn't so big that it would take a lot of work. There was one girl who spearheaded this effort and I hope this haunts her.
The fake suburban gang was able to get the heat off their backs by accusing the town and the police dept of targeting them becuase they were mostly black kids. They came from middle class families so I assume they got their parents involved who then threatened legal action against the town.
