Japan teen axe murderer 'just wanted to kill someone': report

A 19-year-old college girl murdered an elderly woman with an axe and a scarf because she "just wanted to kill someone" news reports in Japan said today.
The student from the prestigious Nagoya University hit 77-year-old Tomoko Mori repeatedly with the axe and then strangled her "because she wasn't completely dead", the Asahi Shimbun said.
The young woman was arrested on yesterday, and reportedly told investigators: "I have just wanted to kill someone since childhood. It could have been anybody."
Mori had become acquainted with her alleged murderer when she tried to persuade the young woman to join a religious group.

The killing allegedly occurred at the student's apartment in Nagoya, central Japan, with an axe the suspect had acquired as a junior high school student, Jiji Press reported.
On the day of the murder, she reportedly tweeted: "I eventually did it."

The student's name was not released because she is a minor under Japanese law.
Crime levels are low in Japan and murder is uncommon, however, occasional killings tend to make headlines because of their lurid nature.
In August a 16-year-old schoolgirl confessed to decapitating her classmate because she "wanted to dissect someone".
