[SS.I 4.0] This document is an index to the first 11,000 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 by the last name of the interviewee. In addition to the master list of names there are more specific lists. One list is devoted to official agencies and is organized by agency location and department; the other list consists of Columbine High School classes, organized by teacher’s last name. The original document was found online with no indication of who created it. It has been heavily edited, expanded, and redesigned for this site.
