Criminal Diaries: Caught on Paper
Eric Harris and Dylan Klebold
Eric Harris and Dylan Klebold
Columbine High School senior Eric Harris (left), 18, kept a diary where he and Dylan Klebold (right), 17, wrote about killing 500 people by invading the school cafeteria, blowing up the school, and then hijacking a plane to New York. Investigators found the diary after the pair killed 12 students and a teacher in April 1999 before killing themselves. Days later, a newspaper received a letter Harris wrote before the killings, blaming the parents, teachers, and students of Columbine for their actions. The teens' journal indicated they had planned the massacre for over a year.
