DENVER -- The two Columbine killers planned the school attack for a year, according to just-published entries from one of their journals.

The newly-released pages are from a journal written by Columbine High School killer Eric Harris.

Victims' families said the pages, obtained by the weekly newspaper Westword and published on its Web site, raised new questions about whether the April 20, 1999 attacks that left 15 dead and two dozen more wounded could have been prevented.

"Sometime in april me and V (Klebold) will get revenge and will kick natural selection up a few notches," Harris wrote in an entry dated April 26, 1998.

In that journal entry, Harris wrote that he and Klebold would park their cars in the school parking lot, walk into the cafeteria during lunch wearing black army pants, carrying bags filled with bombs and guns. Harris wrote he would explain the bags away by saying, "its all for a science/band/english project or something."

They would then start tossing pipe bombs and shooting students.

"I just want a firearm that can hold lots of bullets and that wont jam on me. So ill need lots of clips too. Ill have those strapped on my chest."

In the actual event, Harris and Klebold did set bombs in the cafeteria, many of which failed to detonate properly. They were equipped with four guns, including a shotgun and a TEC-9 semiautomatic pistol.

Most of the carnage was in the library, where they took their own lives after killing 10 students. Another student was killed outside the school and a teacher was shot in a hallway and bled to death in a classroom.

In 2000, a judge ordered that the Jefferson County Sheriff's Office release thousands of documents connected with the case. Tallman said the sheriff's office had been ordered not to release documents that appeared in Westword.

"Pursuant to the court order, the judge made it very clear that we were not to release these materials," said Jacki Tallman, Jefferson County Sheriff's Office spokeswoman Wednesday morning.

Tallman said that the published documents appeared authentic.

"I have not had an opportunity to look at it page for page but some of what I have viewed does appear to be a duplicate of the information we have."

Anger-Management Class

Also among the documents is an essay Harris wrote for a court-ordered anger-management class he took after he and Klebold were arrested for breaking into a van in 1998.

"I am happy to say that with the help of this class, and several other diversion-related experiences, I do want to control my anger," Harris (pictured, right) wrote in the November, 1998, essay.

The publication of the documents, some handwritten, others typed, comes a week after a federal judge threw out eight lawsuits brought by victims' families against sheriff's officials and school administrators over the rampage. The judge said the defendants were confronted "with an unprecedented and rapidly evolving violent situation" the day of the attacks.

Some family members who filed those suits said the entries were new evidence that the attack could have been prevented.

They pointed to an affidavit that was drafted for a search warrant of Harris' home after allegations that he was threatening fellow Columbine student Brooks Brown over the Internet and making pipe bombs.

The affidavit was never submitted to a judge or the district attorney, and sheriff's officials said there was no evidence of a specific threat to the school.

"Had the police put forth a normal effort attached to any type of search warrant, I'm convinced there would have been no attack on Columbine," said Brian Rohrbough, father of slain student Daniel Rohrbough.

"It's just like someone threatening an airliner at the airport -- you can't assume it's a joke," he said.

Still, it's unclear how many of the journal entries would have been written by the time of a police search, or whether they would have been found.

Journal Entries

The journal entries flesh out the picture of Harris as a teen who felt excluded by other kids and frustrated with women. He eventually decided they all must die.

"I hate you people for leaving me out of so many fun things," he wrote. "You people had my phone #, and I asked and all, but no no no no no don't let the weird looking Eric kid come along..."

A page from the day planner of Eric Harris, obtained by Westword (pictured, left) shows his diagram of how he would hide weapons and explosives on his body. The page also shows that Harris had marked out all entries for the day after the planned massacre.

The pages also show Harris and Klebold planned an attack on a far larger scale, and had planned to kill Brown and his family before beginning their rampage at the school. Brown's family was untouched and he was unhurt in the attacks.

Remarking on the possibility that he and Klebold might survive, Harris wrote the two would try to escape to a foreign country where they couldn't be extradited.

"If there isnt such place then we will hijack a hell of a lot of bombs and crash a plane into NYC with us inside (f)iring away as we go down. just something to cause more devistation."
