Eric Harris / Dylan Klebold · Columbine High School
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.

Jeffrey Weise: Timeline [4 pp, 445 Kb]
