According to an interview with an investigative official, it was found that a third-year high school girl living in Tokyo has been missing since 27th of this month, three days ago.
The Metropolitan Police Department was looking for the whereabouts, but when I found out that a couple in their 20s living in Gunma Prefecture was in contact with a girl student, I heard that they said, "I killed the girl student."
The Metropolitan Police Department is investigating the details of the situation by listening to the situation from the couple.
