More than two months before her death, Kathryn “Katy” Benoit told an official at the University of Idaho that she was frightened by her professor, who carried weapons “everywhere, including to campus,” and that she also worried about the safety of fellow students. Benoit, 22, was killed on Aug. 22 by Ernesto Bustamante, with whom she had an intimate relationship. The assistant professor then killed himself in a Moscow hotel room.
