The TV station cites an anonymous law enforcement source at a command post in Clear Creek County. The FBI also tweeted at 12:44 p.m. that there is "no longer a threat to the community."
It's unclear how Pais died. A woman at the scene told CBS Denver she was asked to leave the area because “a naked woman matching the description with a gun was spotted in the area running through the woods.”
Eighteen-year-old Sol Pais wasn't alive when two gunmen in trench coats stormed into Columbine High School on April 20, 1999, and killed 12 of their classmates and one teacher. But federal authorities say the Surfside teen made threats to commit "an act of violence" in Colorado as the 20-year anniversary of the school shooting draws near.
This morning, a widespread manhunt for Pais continues as officers frantically try to prevent another tragedy.
The threats are serious enough that Denver schools are closed today. Extracurricular activities and after-school sports have also been canceled.
As of now, little is known about Pais and her motivation to make the alleged threats. Neighbors told the Miami Herald the teen was a senior at Miami Beach High School who kept to herself. Pais' parents reported her missing Monday night; her father told the Herald she may have "a mental problem."
The Jefferson County Sheriff's Office in Colorado says Pais traveled there Monday and bought a shotgun with ammunition. The threats apparently were not specific to any school, but authorities were concerned because the FBI believes she is "infatuated with (the) Columbine school shooting." Pais was last seen near Columbine in a black T-shirt, camouflage pants, and black boots.
A spokesperson for Miami-Dade County Public Schools told NBC the district is not aware of any threats to local schools:
Our sister paper in Denver, Westword, first reported on the threats yesterday, four days short of the April 20 Columbine anniversary. A story this morning says 16 Denver area school districts are closed and includes a video of a law enforcement press conference.A @MDCPS official confirms that Sol Pais, the subject of a massive manhunt in Colorado, is a current student at @mbseniorhigh School in FL.
