The 18-year-old student was charged Thursday with allegedly planning a school shooting at ACES High School in Everett, Washington. O'Connor was charged with Attempted First Degree Murder for the alleged shooting plot, First Degree Robbery, and Third Degree Assault.

Police officers secured a search warrant for O'Connor's room and discovered an AK-47 and journals detailing his plans.

Police believe the teen used the same AK-47 to rob a convenience store on February 12. They were able to compare the weapon with that seen in the gas station surveillance video by the "...distinctive, abnormally high front sight of the rifle..."

Court documents state he wrote in his journal about how powerful he felt because of how scared the female clerk was.
