## Resource

The episode recounts the unsolved 2000 Setagaya family murders, a brutal crime that claimed the lives of four individuals in their Tokyo home. On New Year's Eve, an unidentified assailant entered the Miyazawa residence, killing the parents and their two young children before staying in the house for hours to consume food and browse the internet. Despite a massive collection of physical evidence, including DNA, fingerprints, and personal belongings, Japanese authorities have never successfully identified the perpetrator. The narrative explores various investigative theories, ranging from a disgruntled local skater to a foreign military member or a hired hitman. These sources highlight how the case’s complexity and the killer's bizarre behavior after the act led to the largest murder investigation in Japan's history. Ultimately, the episode illustrates the lasting impact of the tragedy on the community and the ongoing, decades-long search for legal justice.
