The woman who traveled to Colorado with possible plants to commit a violent act at a school likely killed herself two days before her body was found during a manhunt.

Clear Creek County Undersheriff Bruce Snelling told the Denver Post that Sol Pais, the 18-year-old Miami woman who was found dead at a remote mountainside on Wednesday had likely been dead for two days, and was never aware that she was being pursued by authorities.

As CrimeOnline previously reported, Pais was the subject of a massive manhunt launched Wednesday after investigators received information about a possible, unspecified threat. Schools in the Denver area were closed on Wednesday as authorities searched for the armed woman, who had reportedly purchased a gun shortly after arriving on a flight to Denver from Miami, where Pais lived.

Snelling told the newspaper that when authorities found her body, Pais appeared to have been dead for more than 24 hours of a self-inflicted gunshot wound. Snelling said that Pais had likely been in the area of Mount Evans since Monday, and even if she remained alive for a day or more, she was at such a high altitude that she would not have had any cell phone service. She was also unprepared for the difficult weather conditions, he said.

“She had no idea what occurred from late Monday afternoon to Tuesday when a search for her began and to Wednesday when her body was found,” Clear Creek County  Snelling told the Denver Post. “The logical likelihood was she was here to end her journey.”

“There was no way to find out what was going on based on where she was at,” he said.

While Pais had made statements in her written journals and in conversations with others that she was obsessed with the Columbine school shooting, which had its 20-year anniversary last week, FBI Special Agent Dean Phillips reportedly said at a news conference that Pais never made a specific threat.
