LITTLETON, Colo.—A week-long series of events commemorating the 20th anniversary of the Columbine High School massacre culminated on April 20 with a remembrance ceremony celebrating the lives of the 13 victims slain in the rampage.
On April 20, 1999, two Columbine students, just three weeks shy of graduation, stormed the suburban Denver school armed with shotguns and semiautomatic weapons, fatally shooting 12 students and a teacher before committing suicide.
