The anthrax killings: A troubled mind
Bruce Ivins, who became a respected Army scientist and an authority on the laboratory use of anthrax, had a penchant for vendettas, especially against women.
He roamed the University of Cincinnati campus with a loaded gun. When his rage overflowed, the brainy microbiology major would open fire inside empty buildings, visualizing a wall clock or other object as a person who had done him wrong.
By the mid-1970s, Bruce Ivins had earned his doctorate and was a promising researcher at the University of North Carolina. By outward appearances, he was a charming eccentric, odd but disarming. Inside, he still smoldered with resentment, and he saw a new outlet for it.
