The morning of Tuesday, April 20, 1999 started much the same as any other day in the middle-class town of Littleton, Colorado. None could know, as they went about their normal business, that beneath the calm, an anger had been raging in the hearts and minds of two young men, Eric Harris, 18, and Dylan Klebold, 17. At 11:35 a.m. on that fateful Tuesday, the 110th anniversary of Adolf Hitler's birth, the two teenagers began a rampage through the corridors of Columbine High School that ultimately ended their lives. In their wake they left 13 dead, 25 injured, many seriously, and a town shaken to its core.
