After telling disbelieving friends all weekend that he was going to shoot up the school where he was taunted for being skinny, a smiling 15-year-old Charles “Andy” Williams allegedly opened fire in his San Diego high school bathroom killing two teenagers and injuring 13. It was the worst act of violence at an American school since the 1999 attack by two teenage gunmen at Columbine High School. At first the students thought a cap pistol was going off. But as students fell bleeding, they realised it was a gun and they started fleeing in droves. “We found him in a kneeling position in the bathrom with his hands out [holding] the butt of the gun. He then surrendered,” San Diego County Sheriff’s Deputy Ali Perez said. The shooting victims were identified as Brian Zuckor, 14, and Randy Gordon, 15. The alleged shooter is in custody, and will be prosecuted as an adult.
