fbi agent: During the manhunt, Denver-area schools closed as a precaution, with classes and extracurricular activities cancelled for a half-million students, according to CTV. Police and the FBI were tipped off about Pais after the Miami Beach high school student made troubling remarks to others about her infatuation with the 1999 bloodbath at Columbine High and this weekend's anniversary of the 13 killings, said Dean Phillips, FBI agent in charge in Denver. The body of 18-year-old high schooler Sol Pais was discovered in the mountains outside Denver with what appeared to be a self-inflicted gunshot wound after investigators got a tip from the driver who took her there, the FBI said. He did not elaborate on what she said. We're used to threats, frankly, at Columbine, John McDonald, security chief for Jefferson County school system, said when the manhunt was over. Pais purchased three one-way tickets to Denver on three consecutive days, then flew in on Monday night and went directly to a gun store, where she bought a shotgun, authorities said.
