Nicole Angemi and Maria Q. Kane of the true-crime podcast "Mother Knows Death" dig into the Bryan Kohberger Idaho murders case, the subject of Netflix's "The Idaho Murders: College Nightmare." They unpack Kohberger's criminology PhD background, the DNA evidence tied to the knife sheath, the mysterious tuft of hair found in victim Ethan Chapin's hand, his sudden guilty plea, and their own theory about his possible motive — plus why true crime fans can't get enough of stories like this.
