He Researched Criminal Detection. He Left His DNA Behind. | Bryan Kohberger

In November 2022, four University of Idaho students were killed in their off-campus home. The suspect: a PhD criminology student from Washington State University who had studied how digital surveillance and forensic DNA get killers caught — and who left a DNA-linked knife sheath beneath one of his victims. This episode covers the full documented investigation: the knife sheath, the forensic genealogy breakthrough, the cell phone data showing 12 prior visits to the crime scene, the Instagram messages, the 47-day investigation, and the Alford plea that sent Bryan Kohberger to prison for four consecutive life terms. The Murder Tape Khronicles — forensic true crime, fully documented.
