After receiving a complaint about a foul smell emanating from an apartment in Nishi Ward, Osaka, on July 30, the police went into the apartment and found the bodies of a 3-year-old girl and a 1-year-old boy. The 23-year-old mother of both children has been arrested. It is suspected that she left the studio apartment in late June, abandoning them.

This case leaves many questions unanswered. Married in December 2006, she for sometime blogged about the joy of having and raising children. Divorced in May 2009, she started working in the sex industry in January 2010. She told the police that around that time she came to hate taking care of her children.

But she apparently did not ask for advice or help from anybody. When she placed her last phone call to her parents in Yokkaichi, Mie Prefecture, in late April, she did not give the impression that she was having difficulties, and did not even tell them her address.
