Stabbing Suspect: 'I Have More People to Kill'

"My work is not done, I have more people to kill." That's what Alex Hribal, 16, said after allegedly stabbing 21 at his Pittsburgh-area high school and being tackled by a vice principal, according to a new criminal complaint. The complaint details new charges against Hribal, who was arraigned today by video conference from a juvenile detention center in Pennsylvania, the Pittsburgh Post-Gazette reports. Previously charged with four counts of attempted homicide, he now faces 21—along with 21 previous counts of aggravated assault. The complaint also describes a note authorities found in Hribal's locker, which read in part:

• "I can't wait to see the priceless and helpless looks on the faces of the students of one of the 'best schools in Pennsylvania' realize their previous lives are going to be taken by the only one among them that isn't a plebeian."

Franklin Regional Senior High does have a good academic reputation, with students posting an average SAT score last year of 1603, reports CNN. As for the victims, two were just released from hospital and two remain hospitalized, the Post-Gazette reports. All of them survived the April 9 rampage in which Hribal allegedly cut a path with a pair of 8-inch kitchen knives.
