In December of the year 2000, an unknown male broke into a suburban Tokyo home and killed an entire family. Despite leaving thousands of pieces of evidence in the house, including his clothes, the murder weapon, his DNA, his blood, even his excrement—we are no closer to knowing this man’s identity. There’s no clear motive. And no sign of the case being closed. The Miyazawa family murders are a paradox. They’re a case which has haunted Tokyo police for 22 years now. A case which should be solved. But one which has far more questions than answers.
