On April 20, 1999, a school shooting and attempted bombing occurred at Columbine High School in Columbine, Colorado, United States. The perpetrators, twelfth-grade students, 18-year old Eric Harris and 17-year old Dylan Klebold, murdered 14 students (including one who passed away in 2025) and one teacher; ten were killed in the school library, where Harris and Klebold subsequently died by suicide.
It is still considered one of the most infamous massacres in the United States for inspiring many other school shootings and bombings; the word Columbine has since become a byword for modern school shootings. It is still both the deadliest mass shooting and school shooting in Colorado, and one of the deadliest mass shootings in the United States.
