Tomorrow marks the 12th anniversary of the Columbine High School Massacre. 

On April 20, 1999, in the small, suburban town of Littleton, Colorado, two high-school seniors, Dylan Klebold and Eric Harris, enacted an all-out assault on Columbine High School during the middle of the school day. The boys’ plan was to kill hundreds of their peers. With guns, knives, and a multitude of bombs, the two boys walked the hallways and killed. When the day was done, twelve students, one teacher, and the two murderers were dead. 

Remember the victims and survivors.
