Mass shootings

Woman who made Columbine-related threats found dead

An 18-year-old woman who "made threats to commit an act of violence in the Denver metropolitan area," causing about 20 schools to close on Tuesday and Wednesday, was found dead from an apparent self-inflicted gunshot wound, the Denver FBI office confirmed.

Denver schools close due to Columbine-related threat

Denver-area public schools announced they would close on Wednesday after a Florida woman known to be infatuated with the 1999 mass shooting at Columbine High School flew to Colorado and purchased a gun, the AP reports.

The big picture: The FBI considers 18-year-old Sol Pais a credible threat after she "made threats to commit an act of violence in the Denver metropolitan area." The decision to close all Denver-area schools comes just days before the 20th anniversary of the Columbine shooting.
