A 15-year-old Japanese teenager was arrested Sunday after confessing to killing a friend that was visiting her apartment in Sasebo, Nagasaki Prefecture.
According to the Japan Times, the teen used a blunt instrument to kill Aiwa Matsuo, 15, around 8:15 p.m. Saturday by attacking her from behind and hitting her on the head over a dozen times before strangling her. The teen then cut off Matsuo’s head and left hand. Her body was found on a bed in the suspect’s apartment early Sunday.
The suspect lives alone in her apartment, her parents live in another part of the city. Although her name is being withheld because she is a minor, police quoted her saying, “I did it all by myself.”
There was no word on what charges or punishment the suspect will face.
