DENVER, July 7 (UPI) --
There was more disturbing detail but little new matter in the latest released batch of notes and sketches by the Columbine killers.
More than 900 pages of material were added to the tragic tale of how teenagers Eric Harris and Dylan Klebold conceived and executed their deadly Colorado rampage, the Denver Post says.
The newest batch includes items from years before the April 20, 1999, suicidal attack that killed 12 other students and a teacher. It's loaded with more hateful diatribes, long-running conflicts, a love for violence and preparations for a massacre, the Post reports.
