DENVER — The F.B.I. and law enforcement officials in Colorado were searching on Tuesday for a woman who they said had made threats in the Denver area and was armed and “extremely dangerous.” Security was tightened at schools across the region, with the threats coming just days ahead of the 20th anniversary of the Columbine High School shooting.
An F.B.I. bulletin sent to local law enforcement identified the woman as Sol Pais. She was “infatuated” with the Columbine attack, the bulletin said, and had been “attempting to buy firearms.”
Officials also released an image of Ms. Pais, and said she was approximately 5-foot-5, with brown hair. She had recently traveled to Colorado, they said.

Amy Meyer, a spokeswoman for the F.B.I. in Denver, said the woman had presented “a threat related possibly to the schools.”
Ms. Pais was last spotted in the foothills of Jefferson County, Colo., on Monday night, the authorities said.
The announcement prompted “lockouts,” or heightened security measures, at schools in Jefferson County and the surrounding area. During a lockout, all exterior doors are locked at a school but business continues as usual inside. Police officers aided in end-of-day student release. County officials said that all students and staff members were safe.
During the Columbine High School shooting, on April 20, 1999, two students shot and killed 12 of their classmates and a teacher.
