Watch: Bryan Kohberger's Fellow Inmate Details His Unusual Behavior in JailBryan Kohberger's former classmates are shedding light on his possible motives for committing the brutal murders in Idaho. Months before fatally stabbing four University of Idaho students in November 2022, Kohberger received a master's degree in criminal justice at DeSales University in Pennsylvania-where his fellow students say he took a particular interest in studying mass murderer Elliot Rodger. "At DeSales University, some of the people that Bryan and I studied that were serial killers were Ted Bundy, Jeffrey Dahmer, Ed Kemper and Elliot Rodger," former undergrad classmate Josh Ferraro shared on the Prime Video documentary One Night in Idaho: The College Murders, released earlier this month. "Elliot Rodger, he was a young man in college that was basically jaded and hated his life, because he lacked the attention from friends, family and, most of all, women." At the University of California, Santa Barbara in 2014, Rodger, 22, fatally stabbed his roommates at his apartment before driving to nearby sorority houses and shooting multiple college women. photosCraziest True Crime TV Moments"He then drove around, shot multiple other people in public, and he ended his own life in his vehicle," Ferrano explained. "But after the fact, there was a written manifesto, and he basically tells you, 'This is what I did, this is why I did it.'" As Rodger put it in the 130-page document, "All of those beautiful girls I've desired so much in my life but can never have, because they despise and loathe me, I will destroy."ROBYN BECK/AFP via Getty ImagesAnd according to another DeSales classmate Brittany Slaven, "Bryan was interested in a lot of things that we learned, but he did have more of an interest in Elliot Rodger." In fact, Slaven said Kohberger did not act fazed by Rodger's crimes. "I talked to other girls in the class, where we were all bothered by what Elliot Rodger did," she noted, "but Bryan did not seem bothered."Zach Wilkinson-Pool/Getty ImagesBased on his manifesto, Rodger has been linked to a community of men described as "incels," short for involuntarily celibate, due to their inability to attract women. "Incel, in my professional opinion, is a particularly dangerous version of misogyny," Cortney Franklin, an assistant professor of criminology at the University of Idaho, said in the documentary, "because incel communities have this presence in an online space." As the professor explained, "Elliot Rodger was glorified and valorized and martyred among communities that were coming together in these online spaces."And Kohberger, 30, allegedly had a history of similar problems with college women, according to police. Gary Jenkins, the chief of police at Washington State University-where Kohberger was studying for his PhD-said in the Amazon show, "I did hear about a situation where Kohberger had followed a student out to her car, like trying to flirt with her, and she reported it to someone in the criminal justice department." Investigators also uncovered texts between WSU professors who said that they needed to "do an intervention with Kohberger," with one teacher texting another, "Apparently he's offended several of our female students," according to documents publicly released by the Moscow Police Department July 23.

He has received four life sentences in prison after confessing to the horrific murders. While Kernodle and Mogen were members of the Pi Beta Phi sorority, the documentary noted that Goncalves was a member of Alpha Phi, the sorority that Rodger targeted because he believed they were the "hottest" and "the kind of girls I've always desired but was never able to have," per the BBC. (Rodger ultimately killed two women outside of the house who were from another sorority, Delta Delta Delta.) But despite theories, Idaho investigators were not able to link Kohberger to any of the victims prior to the incident, nor could they uncover a motive for the murders, per prosecutors. He declined to speak in court during his prison sentencing.
