I saw students entering a medium sized lecture room. a Male student pointed a handgun at another student, the handgun was a larger caliber pistol and a silencer was attached to the front of it. The student shot the other student who collapsed. He then walked up past a group of five Chinese students to another male student who sat above the Chinese students and pointed the gun at him. The lone student would not be shot easily and grabbed the pistol by the silencer and took possession of the pistol without being shot. He then used the same pistol and shot the killer in the head. He then asked who would be next. He then walked down to the Chinese students and killed all of them. Then the bullets in the pistol were finished and he could kill no more people using that pistol.
