BOISE, Idaho (AP) - Police say six guns and medications for bipolar disorder and severe anxiety were found in the hotel room of an Idaho professor who committed suicide after he gunned down a graduate student he had recently dated.
    
Investigators on Friday released new details, saying 22-year-old Katy Benoit reported that 31-year-old University of Idaho professor Ernesto Bustamante threatened her several times with a gun before their relationship ended in May.
    
Police say Benoit filed a sexual harassment complaint with the university in June against Bustamante, who denied the allegations and filed his own complaint against her, claiming defamation.
    
Benoit was shot multiple times late Monday. Police say Bustamante - whose friends say alternately referred to himself as a "psychopathic killer" and "the beast" - shot himself in the head shortly after.
