Columbine was the fourth deadliest school killing in US history and the first ever mass murder in a high school by high school students. The only other act of mass killing that took the lives of children had happened in 1927 at the Bath School Bombing.

The Aftermath of Columbine left the United States, and the world, stunned. Children killing children still hits hard and heavy when it happens. Since 1996 nearly 60 school shootings have happened worldwide; although not all were mass murders or had students killing students.
