The FBI in July investigated social media accounts connected to the 16-year-old who shot two students and then himself at Evergreen High School last week, but did not identify the boy or take any further action before the attack, the agency confirmed Monday. Via The Denver Post:
The FBI “opened an assessment into a social media account user whose identity was unknown and who was discussing the planning of a mass shooting with threats non-specific in nature,” the agency said in a statement.
“During the assessment investigation, the identity of the account user remained unknown, and thus there was no probable cause for arrest or additional law enforcement action at the federal level,” the statement continued.
The FBI’s investigation, first reported by 9News, continued until Wednesday’s attack at the high school in the Jefferson County foothills, the FBI said.
