Eric Harris: The Search for Justification [4 pp, 473 Kb]

This article documents Eric Harris’s self-contradictions and vacillating attribution of responsibility for the attack, demonstrating that his justifications cannot be taken at face value.

Influences on the Ideology of Eric Harris [7 pp, 549 Kb]

Eric Harris left records documenting his admiration for Hitler, Hobbes, and Nietzsche. He also may have admired Charles Manson. This article explores parallels between the ideas of these men and those of Harris in an attempt to trace possible influences on his thinking.

Rampage School Shooters: A Typology [11 pp, 600 Kb]

This article appeared in the journal Aggression and Violent Behavior (published by Elsevier) and is reprinted with their permission. The article provides a brief overview of the scholarly literature on school shooters, followed by a presentation of my typology.

The Search for Truth at Columbine [15 pp, 136 Kb]

This article first demonstrates multiple types of problematic reporting, showing that many statements made about Eric Harris and Dylan Klebold cannot be taken at face value. The article then seeks to present a more accurate picture of Harris and Klebold based primarily on the thousands of pages of Jefferson County Sheriff’s Office (JCSO) documents.

Information

11,000 Page Report

These two documents were found online, compiled by an unknown researcher. I have attempted to obtain permission from the researcher to post this material, but have been unsuccessful. I am posting the documents here to preserve this meticulous work. These two documents provide a page-by-page listing of the contents of the first 11,000 pages of JCSO documents.

Pages 1-5,500 [14 pp, 132 Kb]
Pages 5,501-10,937 [17 pp, 143 Kb]
JCSO Columbine Documents Indexed by Name [56 pp, 281 Kb]

This document is an index to thousands of pages of documents compiled by the Jefferson County Sheriff’s Office (JCSO) related to the attack at Columbine High School. This is a guide to summaries of hundreds of interviews organized first by the first name of the interviewee and then by the last name of the interviewee. The original document was found online with no indication of who created it. It has been redesigned for this site.

JCSO Columbine Documents Organized by Theme (version 1.5) [25 pp, 272 Kb]

The attack at Columbine generated over 27,000 pages of documents for the Jefferson County Sheriff’s Office (JCSO), most of which have been made public. These include reports from thousands of interviews with people who knew Harris and Klebold, as well as the killers' personal journals, school planners, academic assignments, yearbook inscriptions, and more. I have organized an index to assist people in locating references by theme. For example, there are pages listing references to Harris and Klebold being harassed, as well as references to Harris and Klebold not being harassed, and references to Harris and Klebold harassing others. There are 10 categories divided into additional subcategories.

Original documents

Dylan Klebold’s Autopsy Report [8 pp, 345 Kb]

Though Klebold drank alcohol and smoked marijuana, the autopsy noted no trace of drugs or alcohol; thus, he was not under the influence at the time of the attack. The report also documents the clothing he wore, including a black t-shirt with the word “Wrath” on it, as well as a “red star medallion containing a sickle and a hammer” on his left boot—a symbol used in Communist Russia.

Dylan Klebold’s Diversion Documents [80 pp, 7.2 Mb]

After Klebold was arrested on January 30, 1998, he participated in a diversion program to keep young, first-time offenders out of the legal system. This document contains his intake paperwork, questionnaires, notes of probation meetings, and assorted forms.

Dylan Klebold’s Journal and Other Writings Transcribed and Annotated [16 pp, 114 Kb]

Dylan maintained a handwritten journal. This document is a transcription of the journal and miscellaneous other writings that were found after his death, along with explanatory comments. 

Eric Harris Online [53 pp, 2.2 Mb]

This is a collection of pages from several Jefferson County Sheriff's Office (JCSO) documents, including the 1997 and 1998 pre-attack records, as well as the massive collection of post-attack materials. There is some redundancy in these sources, but I have chosen to include different versions of the same content rather than choose one version over another. Note: immediately after the attack, someone posted a fake webpage claiming to be Eric Harris. As far as I know, any online content that is not included in the JCSO material is fraudulent. 

Eric Harris: Writings on His Childhood [7 pp, 170 Kb]

This document contains three school assignments in which Harris wrote about his childhood, highlighting the many fun times and pleasant memories he had of his younger years. 

Eric Harris’s Autopsy Report [9 pp, 333 Kb]

Despite Harris’s use of marijuana and alcohol, the autopsy revealed no substances in his system other than fluvoxamine (Luvox), a prescription medication he had been taking for approximately a year. The report also notes that he wore a shirt that read “Natural Selection.” Finally, Harris had a medical condition called pectus excavatum, which means he had a sunken chest. He had surgery at ages 12 and 13 to repair this. Despite the surgery, the autopsy notes that the pectus excavatum was still observable.

JCSO Affidavit [2 pp, 839 Kb]

In 1998, after the Brown family notified the Jefferson County Sheriff’s Office (JCSO) of Eric Harris’s webpages where he documented his bomb-making activity as well as expressed his homicidal urges, an affidavit was written requesting a search warrant to allow law enforcement to search the Harris residence. For some reason, there was no follow through and the search never occurred. 

JCSO Columbine Documents

Following the attack at Columbine, the Jefferson County Sheriff's Office (JCSO) took charge of investigating the incident and accumulated approximately 27,000 pages of documents. Most of these have been released to the public and are available below, but there are some gaps in the sequence of documents. These and other materials (such as videos by Harris and Klebold) can be purchased from JCSO.

A Short Story by Dylan Klebold [2 pp, 420 Kb]

This was written several weeks before the attack at Columbine. Dylan’s English teacher was concerned about the content and addressed this with him, his parents, and a guidance counselor, but Dylan argued that it was just a piece of fiction. The narrator in the story recounts witnessing a man kill multiple students. The killer is described as 6’4”, left-handed, and wearing a black trenchcoat. Dylan himself was approximately 6’4”, left-handed, and wore a black trench coat.

In the weeks leading up to the attack at Columbine High School, Eric Harris and Dylan Klebold filmed themselves talking about their violent intentions.

It has been reformatted for this site.
