The body of a woman aged between 70 and 90 was found at Tokyo's main rail station. The body had been left in a suitcase in a station locker for a month. Tokyo police are investigating the cause of death and examining camera footage to see who left the suitcase.

I think I can help here. It is quite obviously not suspicious and she did it all by herself. After all, if Gareth Williams was able to kill himself inside a padlocked sports holdall, it surely would not be beyond the ability of a small, old Japanese lady to get her body inside a suitcase and inside a locker. They're inscrutable, you know.
