The "Sasebo schoolgirl murder" (佐世保女子高生殺害事件, Sasebo Joshikōsei Satsugai jiken) was the murder of 15-year-old Japanese high school student Aiwa Matsuo (松尾 愛和, Matsuo Aiwa) by a 15-year-old female classmate on July 26, 2014. The murder took place in the suspect's apartment in Sasebo, Nagasaki Prefecture, where Matsuo was beaten with a metal tool, strangled to death, and then partially dismembered and decapitated.

Details
The suspect (15 at the time of the crime, but turned 16 shortly after), whose name has been protected by the police, allegedly posted details and photos of the crime to the popular Japanese message board 2channel, and told police that, "I wanted to kill someone. I bought tools by myself." The suspect had previously attacked her father with a metal baseball bat, prompting him and her step-mother (her biological mother died the previous year) to move her into her own apartment when she began attending high school. It is believed that she first attempted to "dissect" a cat and possessed several medical text books.
Response by television broadcasters
In response to the murder, Fuji TV cancelled the July 31, 2014, broadcast of the fourth episode of the re-edited Psycho-Pass anime, which would have also featured murder of teenage schoolgirls.
Aftermath
The girl's 54-year-old father apologized to Matsuo's family in July 2014 about his daughter's mental health. On October 5, 2014, he was found dead after he committed suicide by hanging.
In 2015, the Nagasaki Prefectural child center, whom the psychiatrist attempted to warn, were found guilty.
