Has there ever been a real life teen macre like in the movies?

Ok I'm kind of a horror buff and I've always been intrigued by teen slasher films considering I'm a teen, and once again I love horror. I was wondering if there has ever been a real murder spree like in the 1st scream that involved a group of high school students. I'm really interested in this so if any of you have an answer put it below!
