In 1991, doctoral graduate Gang Lu, 28, upset that his dissertation did not win a prize, shot and killed University of Iowa Department of Physics and Astronomy Dwight Nicholson, professors Christoph Goertz and Robert Smith and fellow doctoral graduate Linhua Shan. Lu and Shan had once been roommates and Shan had won the academic prize that Lu wanted. Lu also shot associate vice president for academic affairs T. Anne Cleary and student Miya Rodolfo-Sioson, who was working in an office at Jessup Hall. Cleary died the next day and Rodolfo-Sioson was paralyzed from the neck down until her death in 2008. He then killed himself.
