FBI Manhunt Over For Armed Florida Woman Who Threatened Schools

LITTLETON, CO – A 'massive manhunt' for a Florida woman who was said to be obsessed with the Columbine School shooting and had flown to Denver and purchased a shotgun is over.

Sol Pais, 18, was reportedly found dead near the base of Mount Evans, The Denver Channel reported.

Pais was last seen in the foothills of Jefferson County, a JeffCo Sheriff's spokesperson said. Officials considered "armed and extremely dangerous" and a threat to Denver area schools. Authorites urged anyone with information to call 911 or the FBI's hotline.

The Miami FBI notified the Denver branch Tuesday morning that Pais was "infatuated with the Columbine school shooting" and had flown from Miami to Denver Tuesday, Agent Dane Phillips said in a press conference at the FBI headquarters Tuesday night. After leaving the airport, Pais went to a gun store and bought a pump-action shotgun and ammunition in Littleton, officials said. She then was taken to an area near the foothills in Jefferson County.

In Surfside, Florida, a man who identified himself as Pais's father told ABC News that he last saw his daughter on Sunday. He told reporters the ordeal has "been a nightmare." Neighbors told ABC that Sol Pais was a student at Miami Beach High School.

It was still unclear what threats Pais had made, and how she came to the attention of the Miami FBI.

JeffCo Schools initiated a "lockout" Tuesday afternoon, but released students at their regular times. Extra school security and officers were on-hand across the district to watch the student dismissal. A lock-out is a soft emergency response where no one is permitted to leave or enter the buildings.

The Colorado Department of Education was scheduled to conduct a conference call at 3:30 a.m. Wednesday with law agents and school superintendents to discuss the situation for Wednesday's school day, the Denver Post reported. School districts will make announcements in the early morning about whether school will be held Wednesday.

The Colorado Department of Education referred to the threat as made by "an individual identified by the FBI" and recommended that all schools in the Denver area conduct a "lockout and controlled release immediately."

The district said the schools affected were Columbine High School, Blue Heron Elementary and Leawood Elementary, as well as 14 other mountain schools in JeffCo.

As the 20th anniversary of the 1999 Columbine High School mass-shooting approaches, school district officials and law enforcement are on guard for copycat incidents.

In December, when the FBI reported computer hostage threats around the country, a hoax caller told officials that a bomb was planted in the Columbine High School Library. Jeffco and local police officials responded but found no evidence.
