Columbine, Jefferson County Sheriff’s 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. Note: This massive document has been broken into several approximately 1000-page segments, each of which may be downloaded individually.
