For a week, this community has been searching its soul, reports CBS News Correspondent Bill Whitaker. How could it have missed noticing that two of its young men had murder in their hearts?
But Littleton resident Randall Brown says he saw it in Eric Harris and on his Web site -- and it scared him. On Wednesday, CBS News obtained a copy of Harris' Web pages. The signs were clear and chilling.
Harris wrote: "I just kill! God, I can't wait till I can kill you people. I'll just go to some downtown area in some big [expletive] city and blow up and shoot everything I can feel no remorse, no sense of shame. I don't care if I live or die in the shootout. All I want to do is kill and injure as many of you [expletives] as I can."
He continued: "You all better hide in your houses, because I'm coming for everyone soon and I will be armed to the [expletive] teeth and I will shoot to kill and I will [expletive] kill everything!"
Brown says he contacted the authorities after seeing the Website. "I took it to the police over a year ago and nothing was done," he said.
Harris also customized the violent computer game Doom to include a room with his own personal victims. Brown says another version targeted him and his family. "Eric created a level on Doom, using our neighborhood as the matrix and our house as the main house, the last house... for the guy you have to kill," Brown said.
So when the killing started at Columbine High, Brown wasn't surprised to hear the name Eric Harris. That day, his wife Judy was at the home of her good friend, Sue Klebold, the mother of the second gunman.
Judy Brown told National Public Radio that at first they didn't know Dylan Klebold was involved. As police searched the house, Dylan's mother was glued to the TV. "She wants to know, 'Was it my son?' Brown said. She's telling him (the officer), 'Let me go up there. If it's my son, I can stop him.' We didn't know if it was Dylan. We kept praying it wasn't."
Then Brown says her own son, a student at the school, called. "He said, 'Mom, it's Dylan. They just put it on the TV.' I said, 'Did you see it or did they say it?' He said, 'Mom, it's in writing: Dylan Klebold.' So I told her."
