Bruce Ivins , the senior bio-defense researcher at United States Army Medical Research Institute of Infectious Diseases ( USAMRIID ) , before allegedly being driven to suicide by the allegations that he was the " sole perpetrator of the 2001 anthrax attacks " , reportedly had a " long and strange obsession " with Kappa Kappa Gamma , as well as with other sororities such as Chi Omega . Ivins reportedly became obsessed with Kappa when he was rebuffed by a woman in the sorority during his days as a student at the University of Cincinnati . The letters containing anthrax spores ( which eventually killed 5 people and injured dozens more ) were mailed from a drop box approximately 300 feet from a KKG storage facility at Princeton University , and only 60 feet from the KKG office . A US Government investigative panel , called the Expert Behavioral Analysis Panel , issued a report in March 2011 which detailed more of Ivins ' obsession with the sorority . According to the panel 's report , Ivins tormented sorority member Nancy Haigwood at the University of North Carolina . Ivins stole her notebook , which documented her research for her doctoral studies , and vandalized her residence
