(FOX 2) - Twenty years ago this month Columbine High School in Colorado became the scene of one of the worst school shootings in history.
There are new fears as the FBI looks for a woman who made a credible threat against the school. The 18-year-old who is allegedly obsessed with Columbine, traveled there Monday night and made the threat.
Police say they received the "credible threat," but, the threat did not name a specific school. Nearly 20 schools in Jefferson County went into 'lockout mode,' meaning exterior doors are locked, but inside, operations and classes continue as normal.
Officials are now seeking 18-year-old Sol Pais from Florida in connection with the threat. She's said to be armed and dangerous, and 'infatuated' with Columbine.
"Any threats involving Columbine, or our schools, we take at an elevated rate, so, we're always aware of the situation here," said John Hickenlooper.
Colorado's former governor and presidential candidate was met with people impacted by other mass shootings. Michael Davis' daughter was killed in 2013 at her school in the same district as Columbine. He told Hickenlooper he'd like to see more funding go to educators.
Davis says "Troubled kids in our schools, and nobody knows about it. the teachers and administrators are the first line. they need to see that, and they need support and help."
Columbine survivors acknowledge how different things are for their own kids twenty years after they experienced the horror of gunfire in the classroom.
Johnson says "It just made me really sad that our kids have to do lockdown drills, and have to be talked to about these kind of things."
