Get ready for the most insane, frustrating unsolved case..... The year is 2000 in the Setagaya Ward in Tokyo, Japan and the Miyazawa family consisting of Mikio, Yasuko, 8-year-old Niina and 6-year-old Rei were found murdered in their home. The killer didn't stop there, though. This killer did not just kill and flee, but instead drank some tea, ate some ice cream, slept on the couch and took a dump in the toilet and left it there. Is this the mind of a brilliant killer or a complete idiot? Well, they still haven't been caught today, so you decide.
