7 … and Every Day... Trauma room specialists stand helplessly as the mother and brother of a teenager killed in a drive- by shooting collapse in grief on the hospital floor. The family was allowed to see the boy's body, which lies in a nearby room, just moments after the emergency room team failed to revive him.

8 Washington, DC. Thursday, February 10, 2000 'JUST TOTALLY SENSELESS'; TWO WILSON HIGH SENIORS SHOT DOWN AFTER LEAVING GAME Two Students Shot Outside D.C. School The Associated Press Wednesday, April 5, 2006 Public Schools spokeswoman Roxanne Evans said that a 19- year-old male student was shot in the back around 9:15 a.m. E DT, and that he was being treated for serious injuries. SANTEE, Calif., March 6 -- San Diego County sheriff's investigators said today that 15-year-old Charles "Andy" Williams took a.22-caliber long-barrel revolver from his father's locked collection of weapons, brought as many as 40 rounds of ammunition to his high school in his backpack and fired 30 of them during the shooting rampage in which the boy allegedly killed two schoolmates and injured 13 others.

9 Washington Post, March 7, 2001 In the nearly two years since the massacre at Columbine High School, officials at Santana High School developed elaborate security plans for the campus. There were phones in every classroom. Security guards patrolled the hallways with two-way radios. And a sheriff's deputy was assigned to visit the campus each day. But even with that elaborate security net, school officials could not avert Monday's shooting rampage at the suburban San Diego school because friends of accused gunman Charles "Andy" Williams -- and the one adult who heard Williams's plans -- did not turn him in.
