18, and Dylan Klebold, 17, high school students, went on a shooting rampage on April 20 at Littleton, Colorado's Columbine High School, killing 12 students and 1 teacher before turning guns on themselves. The pair, who were members of the school's “trenchcoat mafia,” had been planning the attack for a year and were armed with sawed-off shotguns, a semiautomatic rifle, and homemade bombs. They targeted athletes and minorities. The tragedy led to soul-searching in Washington, with politicians blaming everything from Ritalin to the entertainment industry to day care for the deadly spate of school violence.
