Today is the ten-year anniversary of the now fourth-worst school shooting in US history, and the worst at a high school. 13 people were killed when Dylan Klebold and Eric Harris, names now synonymous with violence and terror, opened fire with six separate weapons, set off a bomb, and prepared two other bombs to explode (which failed to detonate) at Columbine High School, a rural and quiet suburban town outside of Denver. They killed themselves after being surrounded by police.
A candlelight vigil was held last night, the school is closed today, and memorials are being held all across the country today to honor the memory of those who died. A large memorial was erected nearby and dedicated in 2007. Click here to visit it.
