The Killing of a Yaka Yamashita

Yaka yamashita was found unconscious and taken to hospital. She succumbed to her injuries seven days later. An investigation into ayaka's death failed to unearth any suspects. Authorities suspected her killer was also responsible for stabbing a nine year old girl that day as well, seriously wounded, but not fatally. They theorized that the murder may be related to a similar attack where a group of girls had been set upon by a male yielding a hammer earlier that month.
