The lowest point of human existence is manifested in some of the most gruesome murders. But unfortunately, the Setagaya's family murders are just a grain of sand on a beach. There are many other unsolved cold cases like The Zodiac Killings, Jack the Ripper, The Women of Ciudad Juarez and The Black Dahlia, among many others. The only silver lining is that such unsolved family murders unite the world in condemning acts of taking the lives of others.
