In the wake of the shootings there was a staggering amount of paperwork and evidence to go through. The reports alone make enough reading material to keep even the most dedicated investigator busy for months, perhaps years. The paper trail begins even before the shootings, dating back well over a year prior to the violence of April 20, 1999. What was uncovered brought only a few answers; in most cases what was left behind has only led to more questions.
911 calls Transcripts and audio files from 911 calls placed from inside the school. Information about the call made by teacher Patti Nielson from the library during the shootings.
