Bryan Kohberger had serial killers on the brain in the weeks after he brutally murdered the four University of Idaho students. The former criminology student stabbed to death Kaylee Goncalves, Madison Mogen, Xana Kernodle, and Ethan Chapin at their home in Moscow, Idaho, on November 13, 2022. In the time that followed, Kohberger tried to erase any evidence tying him to the crime, such as erasing his purchase history for the murder weapon on Amazon. However, he was sloppy, making big mistakes that resulted in his arrest.
