In this episode, we explore the chilling case of Matsuzawa Kayo, a Japanese woman who vanished in Auckland, New Zealand, in 1998. A month after her arrival, Kayo’s dismembered body was discovered in an emergency exit stairwell, sparking a high-profile investigation. Police efforts were thwarted by missing security footage, suspicious log deletions, and lack of physical evidence, leading to several dead-end suspects, including a guard and a Ukrainian backpacker. Over time, the case went cold, but it remains active, with recent hints of new evidence potentially linking the suspect to other crimes. Despite the years that have passed, New Zealand authorities and Kayo's family hold onto hope for justice.
