Confirmed Threat

On November 1, 1991, Gang Lu, a 28-year-old physics PhD graduate, fatally shot four people in Van Allen Hall and mortally wounded a fifth in Jessup Hall on the University of Iowa campus before killing himself. Lu opened fire during a research group meeting in Room 309 of Van Allen Hall at approximately 3:42 PM CST, killing physics professors Christoph Goertz and Robert A. Smith and post-doc Linhua Shan, then killed department chair Dwight Nicholson on the second floor before walking to Jessup Hall, where he shot associate vice president T. Anne Cleary (who died the following day) and student employee Miya Rodolfo-Sioson, who was left permanently paralyzed.

Context

Background

The 1991 University of Iowa shooting was one of the deadliest campus shootings in U.S. history at that time. Gang Lu, who had earned his PhD in physics earlier that year, was enraged that his dissertation was not nominated for the Spriestersbach Dissertation Prize, which instead went to fellow student Linhua Shan, one of Lu's victims. Lu carried a .38 Special revolver and targeted specific individuals: professors Christoph Goertz and Robert A. Smith and post-doc Linhua Shan in Van Allen Hall Room 309, department chair Dwight R. Nicholson on the second floor of Van Allen Hall, and associate vice president T. Anne Cleary in Jessup Hall. Cleary died the following day at University of Iowa Hospitals. Student employee Miya Rodolfo-Sioson was shot and paralyzed from the neck down; she died in 2008 at age 40. The shooting occurred years before the Clery Act emergency notification requirements were enacted and there was no campus-wide alert system. The incident later inspired the 2007 film Dark Matter.
Analysis

Key Findings

The attack spanned two buildings three blocks apart, illustrating how a determined shooter can move between locations faster than word-of-mouth warnings can travel
No mass notification system existed at the University of Iowa in 1991; the Clery Act had only been signed into law the year prior and did not yet include emergency notification mandates
Gang Lu's methodical targeting of specific individuals he blamed for his academic grievances foreshadowed later workplace-violence-style campus shootings
Miya Rodolfo-Sioson, paralyzed at age 23, became a disability rights advocate before her death in 2008
Outcome
Gang Lu died of a self-inflicted gunshot wound in Jessup Hall. His motive was tied to a dispute over the Spriestersbach Dissertation Prize, which was awarded to a fellow student. Rodolfo-Sioson lived as a quadriplegic until her death in 2008.
