Episode Details

The provided transcript details the long-awaited resolution of the 1983 cold case murder of Diana Hanson, a 22-year-old college student who was attacked while jogging in Las Vegas. For decades, the investigation stalled despite the discovery of a bloodstain belonging to an unknown male at the crime scene. The breakthrough finally occurred in 2021 through the use of advanced genetic genealogy, which first identified Johnny Blake Peterson as the killer of another young woman, Kim Bryant. Corroborating evidence from Peterson’s ex-wife, who recalled finding a Sony Walkman and clothing in his vehicle years earlier, helped solidify the link. While the perpetrator died of an overdose before he could face trial, the discovery provided much-needed closure for Hanson's family and her boyfriend, who became a police officer because of the tragedy. This case highlights the power of philanthropic funding and modern DNA technology in solving violent crimes that have remained a mystery for generations.
