One Goh Ko (One L. Goh), a former nursing student, who opened fire Monday morning at Oikos University, a small Christian institution in Oakland, Calif., first told his former classmates to line up against a wall before pulling a handgun and sending students fleeing in panic, a witness told the Oakland Tribune. He killed seven and injured three. This is eerily reminiscent of Virginia Tech shooter Seung-Hui Cho. Goh, who is commonly known as One-L, reportedly used a 45-caliber pistol in the shooting. One Goh Ko, 43, is from Castro Valley. One of the victims of the Oikos University massacre has been identified as Lilia Sim.
