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.
