It’s hard to think of a biology teacher as a dangerous person. Boring? Long winded? Possibly. But dangerous?

Well, not only did biology professor Amy Bishop allegedly kill three colleagues and wound three more in a shooting rampage at the University of Alabama in Huntsville on Friday, but now the Boston Globe reports she was a subject of an ATF-Postal probe in an attempted bombing of a Harvard Medical School prof in 1993.

The paper reports that Bishop and her husband “were questioned after a package containing two pipe bombs was sent to the Newton home of Dr. Paul Rosenberg, a Harvard Medical School professor and physician at Children’s Hospital Boston. At the time, Bishop was working as a postdoctoral fellow in the hospital’s human biochemistry lab.”

The paper reported that Bishop’s husband, James E. Anderson, “acknowledged that he and his wife were questioned by authorities about the 1993 mail bomb case, but said neither of them was a suspect. Rather, they were “subjects’’ of the attempted bombing investigation, he said.”

The husband told the New York Times that he had a letter from the ATF saying that they had been cleared in the matter.
