A news magazine has defied a ban on identifying minors in criminal cases by naming a 19-year-old student who allegedly bludgeoned an elderly woman to death.

Tokyo-based weekly Shukan Shincho on Thursday ran an in-depth article about the Nagoya University student, urging a national debate on the reporting of juvenile crime.

Headlined "Evil nurtured within the heart of the Nagoya University female student; the resume of a 19-year-old killer of an elderly woman," the four-page article named the suspect, printed two photographs of her and quoted people who had known her in childhood.
