The University of Iowa shooting took place at the University of Iowa in Iowa City, Iowa on November 1, 1991. The gunman was Gang Lu, a 28-year-old former graduate student at the university. He killed four members of the university faculty and one student, and seriously wounded another student, before committing suicide. == Perpetrator and motives == The perpetrator of the shooting was 28-year-old Gang Lu (born 1962) (), a former graduate student at the University of Iowa. Lu was a physics and astronomy student who had received his doctoral degree from the university in May 1991. (His dissertation was titled ''Study of the "Critical Ionization Velocity" Effect by Particle-in-Cell Simulation''.) He was still living in Iowa City after he had graduated. As a graduate student Gang Lu was primarily a loner who was perceived by at least one other graduate student to have a psychological problem if challenged and was reported to have had abusive tantrums. In the months prior to the shooting, Lu wrote five letters explaining the reasons for his planned actions. According to university officials, four of the letters were in English and were intended to be mailed to news organizations. One letter was written in Chinese. The letters have never been released to the public. Lu was infuriated because his dissertation did not receive the prestigious D.C. Spriestersbach Dissertation Prize. This prize included a monetary award of $2,500. Gang Lu believed that winning the prize would have made it easier for him to get hired as a professor. Lu was unable to find work because of the recession. Normally, in this instance, the physics and astronomy department would have given Lu a temporary postdoctoral fellowship, but there was not enough money to support him. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「University of Iowa shooting」の詳細全文を読む スポンサード リンク
