Bryan Kohberger, a former criminology Ph.D. student at Washington State University, believed he could execute “the perfect murders.” However, his plan was thwarted by a crucial mistake, as revealed by author James Patterson. Kohberger’s oversight of leaving a knife sheath at the crime scene ultimately led to his arrest. This revelation is part of Patterson’s collaboration with investigative journalist Vicky Ward in their new book, “The Idaho Four: An American Tragedy,” and the Prime Video docuseries “One Night in Idaho: The College Murders.”
Kohberger, described as an awkward and arrogant introvert, struggled with social interactions, particularly with women. Despite his belief in his own popularity, he often made others uncomfortable. His inability to connect socially was evident during his time as a teaching assistant, where he reportedly graded female students poorly. The book suggests that Kohberger may have been inspired by Elliot Rodger, a notorious figure known for his violent acts driven by social and sexual isolation.
On November 13, 2022, Kohberger fatally stabbed four University of Idaho students: Madison Mogen, Kaylee Goncalves, Xana Kernodle, and Ethan Chapin. He later pleaded guilty to these murders to avoid the death penalty and now faces four consecutive life sentences. The small town of Moscow, Idaho, was deeply affected by the crimes and the ensuing media attention.
Patterson and Ward conducted over 300 interviews to explore Kohberger’s background and motivations. The book highlights Kohberger’s frustration with women and his possible identification with “incels,” or involuntary celibates. It also draws parallels between Kohberger and Rodger, noting similar behaviors such as visiting gun ranges and attempting to engage women in bars.
Dr. Katherine Ramsland, a professor mentioned in the book, explains that killers often develop tunnel vision during their crimes, leading to critical mistakes. This was evident in Kohberger’s case when he left behind the knife sheath that became key evidence against him.
The murders brought unprecedented attention to Moscow and Pullman, Washington. Patterson emphasizes the responsibility of true crime storytellers to handle such cases with care. Despite Kohberger’s guilty plea, questions remain about his motives and whether more information will emerge.
