BOISE, Idaho (AP) -- An Idaho professor who gunned down a graduate student he had dated and then took his own life two months ago had disclosed his bipolar disorder shortly after he was hired in 2007, according to a detailed timeline released Wednesday.
University of Idaho President Duane Nellis discussed the release of personnel records for Ernesto Bustamante, 31, during a press conference.
Bustamante was found dead in his hotel room on Aug. 23 with six guns and medications for bipolar disorder and severe anxiety. Moscow police a day earlier had found the body of 22-year-old Katy Benoit, who was shot nearly a dozen times outside her Moscow home.
Bustamante disclosed to the psychology department that he managed his mental illness with medication after starting his employment on Aug. 12, 2007, the university said in the timeline.
"We, as an institution when we hire people, we're not allowed to ask for medical conditions, or anything like that," Nellis said during a press conference on the Moscow campus. "Bipolar is something that's certainly treatable."
As early as the fall of his first semester, three or four students went to psychology department chair Ken Locke to express concerns about Bustamante's behavior, saying he was "flirtatious" and showed favoritism to students.
Bustamante, who is originally from Venezuela, was confronted about the complaints and told Lock that his interactions with a student who was also Hispanic had been misunderstood, the university said.
Benoit had met Bustamante last fall when she took a psychology course he was teaching, and by the end of the semester they were dating. The relationship ended in May, after he put a gun to her head and told her how he would use it to kill her. She told others he had threatened her with a gun twice before.
Bustamante had been known to alternately refer to himself as a "psychopathic killer" and "the beast," according to police. After the couple split, Benoit alerted school officials that she was becoming increasingly concerned for her safety and filed a sexual harassment complaint with the university on June 12.
Bustamante denied the allegations and filed his own complaint against her on July 8, claiming defamation of character.
School officials had contact with Benoit more than a dozen times to discuss the situation and urge her to take safety precautions. The final meeting came Aug. 22, the first day of the fall 2011 semester and the same day police said Bustamante shot Benoit 11 times with a .45 caliber handgun outside her home.
Nellis announced Wednesday that the university would take action to bolster its consensual relationship policy and expand sexual harassment training.
"We've come together in the wake of an unthinkable tragedy," Nellis said. "Going forward we'll be stronger and wiser."
Media outlets are expected to receive Bustamante's personnel documents on Thursday. A judge ordered the documents released Oct. 3 after the university and several media outlets petitioned the court to rule they were a matter of public record.
