Police reports filed in Latah County reveal a former Associate Professor at the University of Idaho, who police say shot and killed a graduate student then himself, was a self-admitted "psychopathic killer" who threatened the student several times with a gun before he shot and killed her on Monday.
According to the roommates of 22-year-old Katy Benoit, the student was sexually involved with Ernesto Bustamante, but broke things off in March. Friends say Benoit claimed the former professor threatened her several times with a gun and even put the gun in her mouth at one point.
A friend of Bustamante told police that he owned several handguns and had multiple personality disorders, one which he called "psychopathic killer" and another he called "the beast."
According to the documents Benoit filed a complaint with the University of Idaho against Bustamante in June. Bustamante was either fired or allowed to resign on Friday as a result of the complaint.
