XX Cheng, our CS Ph.D. student, was substitute-teaching CS 4414 in 205Norris Hall this morning. Around 9:45 very loud noises were heard from thecorridor. XX and one student went outside to see what was happening. Whatthey saw was a young men with a gun exiting a classroom. As soon as he saw them he pointed the gun to them (and shot at them but missed). XX and the student ran quickly back in the classroom and closed the door after them;
XX told the students to lay down; three men from the classroom rushed to the door and held it closed. The killer tried several times to force-enter the 205 classroom. He then shot two bullets through the door inside the classroom. Fortunately these bullets did not hit anybody inside. The killer gave up and went on to other classrooms ...
