Idaho killer left behind 'catastrophic' evidence that fast-tracked his capture, investigators reveal

The sources provide an extensive examination of the 2022 quadruple homicide in Moscow, Idaho, focusing on the brutal murders of four University of Idaho students and the subsequent investigation that led to the swift arrest and eventual guilty plea of Bryan Kohberger. The first source details the crime scene, the initial mystery surrounding the lack of motive or weapon, the sole surviving witness's account, and the victims' backgrounds, concluding with Kohberger's 2025 plea deal to avoid the death penalty. The second source offers a technical study of Investigative Genetic Genealogy (IGG), explaining how this forensic method uses Single Nucleotide Polymorphism (SNP) analysis and consumer DNA databases to identify suspects through distant relatives, illustrating its power by detailing how DNA left on a knife sheath was the "catastrophic" evidence that linked Kohberger to the crime within six weeks. Together, the episode highlight the transformative role of IGG in modern crime solving while also noting the ethical and privacy concerns inherent in its use.Become a supporter of this podcast: https://www.spreaker.com/podcast/murder-files-unsealed--6017387/support.
