BALDWIN: We're back. You're watching CNN. I'm Brooke Baldwin. Months before Tuesday's shooting in a Colorado school that killed one student and injured eight others, the school board asked for an investigation after a complaint from an anonymous parent who said that she was afraid of -- quoting her -- "another Columbine." Now, for the first time, that woman who says that she -- she's that anonymous parent, is talking exclusively to CNN. She still wants to remain anonymous because of fear of retaliation. But CNN confirmed she has a student in the school, and she knew details about the allegations.</s>UNIDENTIFIED FEMALE: It looked like to me that there were potential for having another Arapahoe or Columbine shooting, and that I was seriously concerned about it. When you mix not reaching out, when you mix a pressure cooker environment, where students are stressed out and overworked, and they don't get enough sleep, and they feel suicidal, or they feel aggressive towards one another and are not being disciplined for it, when you don't listen to parents' concerns, when you don't support teachers' concerns, when you don't give teachers the kind of training that they need or the support that they need, those are the elements that we need for the perfect storm, for something like a Columbine or a -- some kind of imminent threat to our children's safety in the school, whether it be a bomb, or an active shooter, or a suicide.
