With the growing popularity of mobile phones, many people were able to place calls from inside the school during the shootings. Others used hall pay phones and office phones to call 911, family, and friends. In the neighborhood surrounding the school, people who lived nearby called the police to alert them to the tragedy unfolding.

Call after call flooded the emergency lines. The most chilling of the lot: A call made by an injured substitute teacher calling from the library just before the shooters entered and started killing people. The following is taken directly from the FBI Report, which was marked by the FBI as Classified material on 07-16-99. It was Declassified on 01-15-02, with the redacted Columbine Documents released to the public in 2006. Misspellings are as they appear in the original report.

F.B.I. report excerpt about the Library 911 call:
"On April 20, 1999, Eric Harris and Dylan Klebold shot and killed twelve students and one teacher at Columbine High School Littleton, Colorado. During the incident, teacher Patty Nielson placed a call to 911 Emergency. Neilson was in the library when she placed the call. The 911 operator answered the call stating "911" at 11:27:47 a.m. The phone call lasted 26 minutes. During the call, noises including gunshots, explosions, screaming, and yelling can be heard. The initial backround noises heard come from the hallway just outside of the library. Four minutes and ten seconds into the call, Harris and Klebold entered the Library and begin shooting. They left the Library eleven minutes and forty-five minutes into the call. The remaining gunshots and explosions heard on the tape occur in the Cafeteria, Science classroom area or the hallways of the school."

The audio clip from the library 911 call cuts off right after the shooters enter the library. If you listen closely you can hear their voices in the background, toward the end of the clip. Refer to the transcript to see what they are saying as it's difficult to understand on the recording.

FAQ - At the time of this posting, the audio clip from Patti's phone call hosted here is the longest clip publicly available. While a longer copy does exist, it has never been released to the public and likely won't be due to the fact that people were being killed while the dispatcher was still recording the call.

Below are linked several files having to do with Patti's 911 call as well as other calls placed by individuals who were inside Columbine High School during the shootings. The content is disturbing so please look and listen with caution.
