"Teen Arrested for Plotting School Shooting on Columbine Anniversary"

An 18-year-old California student, Sebastian Villasenor, was arrested for allegedly planning a school shooting at Ontario Christian High School on the 25th anniversary of the Columbine massacre. He had access to multiple firearms and ammunition and had made specific threats against at least five individuals. Although he did not have a written "hit list" or manifesto, authorities believe he was fixated on carrying out the attack. The police chief praised the classmate who reported Villasenor as a hero for potentially preventing a tragedy.
