11 h 19 m, 20 abr 1999 ano - The Jefferson County Dispatch Center received a 911 call about a staged grass fire

Descrição:

At 11:19 AM the Jefferson County Dispatch Center received a 911 call from a person who reported hearing an explosion in a field on the east side of Wadsworth Boulevard (about 3 miles from Columbine High, between Ken Caryl and Chatfield avenues). Two backpacks loaded with pipe bombs, aerosol canisters and small propane tanks had been placed in an open grassy space three miles southwest of the high school. Only the pipe bombs and one of the aerosol canisters detonated but the explosion and subsequent grass fire were enough to divert the attention of the Jefferson County Sheriff's Office and the Littleton Fire Department. Police dispatch radioed the event out. (This audio clip is about 40 minutes long and includes 911 calls as well as police communications. It begins with the explosion in the field and continues past the library shootings.)
