  • TIME LINES

    From the beginning of the investigation into the shootings at Columbine High School, a timeline was established to record the significant events of April 20, 1999.  The timeline was updated several times as new information became available from all the different sources.  The result is a PRIMARY Timeline, which offers a brief chronological account of the events of April 20, 1999, the movements of Eric Harris and Dylan Klebold, the law enforcement and emergency responses and the media coverage.  This timeline is the basis for a more detailed, comprehensive NARRATIVE timeline of the April 20 events that is included in this report.

  • CRIME SCENE DIAGRAMS 

    The following diagrams show the significant events and movements of Eric Harris and Dylan Klebold on April 20, 1999.  The witnesses to each event are shown as green dots.  The injured are shown as yellow only during the event that caused the injury and return to green if they witnessed other events.  The deceased are shown as red and convert to gray once that event has passed.  Harris is shown as a red dot with the letter H inside it and Klebold is shown as a blue dot with the letter K inside it.    The diagrams only show the portions of the school where the events are occurring.  Where appropriate an overview of the school is shown with a red square indicating what area of the school is magnified.   Harris and Klebold are not shown on every diagram, but rather only during the events that witnesses actually observed them.
