DNA cracked the case in the brutal murder of a college student over three decades ago along a popular hiking trail. The Prescott, Arizona murder of Cathy Sposito in June of 1987 was unsolved but remained open and active for 36 years. In September 2023, the Yavapai County Sheriff named Bryan Scott Bennett as Sposito’s killer, but the investigation found Bennett also had more victims who were attacked and sexually assaulted in northern Arizona. While the discovery solved several cases, an unexpected twist is the reason why there’s no arrest now.
