More than a dozen school districts in Colorado are closed after the FBI and local police warned of an 18-year-old woman who is “armed and dangerous” in the Denver area, reports NPR. The suspect, Sol Pais, was found dead in an apparent suicide on Wednesday at the base of a mountain 40 miles west of Columbine High school, the Associated Press reports. She had flown from Miami to Denver on Monday and immediately bought a pump action shotgun and ammunition, said FBI agent Dean Phillips. Pais had “made some concerning comments in the past” and had an “infatuation” with the 1999 Columbine shooting and its perpetrators, Phillips said. He said law enforcement had no specific information about a threat to any one particular school, but it was a “credible threat certainly to the community and potentially to schools.”
Pais had no specific known connections to Colorado. Columbine High School and several others in Jefferson County were placed on “lockout” Tuesday, which means entry and exit are restricted while classes continue as usual. Two students at Columbine High School killed 13 people and injured 24 more and then killed themselves on April 20, 1999. The incident has inspired other school shootings.
