This happened the year before I moved to the school, but at the beginning of the new school year I heard a lot of whispers about it and once saw a teacher shut down a conversation amongst a group of students about it.
So only ever hearing this third hand, it went something like this: a group of jocks abducted one of their friends after school one day. They took him out to someone's farm land blind folded, tied him up in a tree (or on a cross) and terrorized him by doing crazy shit like running a chainsaw close between his legs.
The kid they did this too immediately became an outcast skater punk who played in the local metal band. I got to know him a little bit through my girlfriend at the time and he was really cool. I have no idea why they did that too him. I don't know what, it any, punishment was handed down to the perpetrators. I know the school district wanted to expel them but it didn't happen during school.
It was common that year for kids from the neighboring town to drive by and yell stuff like "HEY LET'S GO CRUCIFY ONE OF OUR OWN PLAYERS!"
I also got reprimanded by a teacher for joking about kidnapping a friend of mine in order to force him to pay back the various $5 he had borrowed from everyone in our friend group. It was 100% a joke of course but I didn't realize what poor taste it was at the time.
