Columbine High School massacre

The Columbine High School massacre occurred on April 20, 1999, in Littleton, Colorado, when two students, Eric Harris and Dylan Klebold, carried out a planned attack, killing 12 students and one teacher, and injuring many others before taking their own lives. The incident was driven by complex motives, including bullying, mental health issues, and access to firearms. It highlighted vulnerabilities in school safety and led to widespread debates about gun control, bullying prevention, and mental health awareness, profoundly impacting policies and awareness around school security and student well-being.
