A 35-year-old woman on Wednesday was sentenced to 11 years in prison for killing her 5-year-old son by throwing him from a window in their 13th-floor apartment in Tokyo's Arakawa Ward in December 2014.
The sentence was handed down by the Tokyo District Court against Ai Kato who had pleaded not guilty.
Kato had testified that she left the window open in the bedroom where her son Koki Takahashi was and then had gone to the toilet, Sankei Shimbun reported. When she returned, the boy's body was lying on the ground below at around 11:15 p.m. on Dec 29, 2014.
The boy's father looked for his son when he got home and became concerned. A passerby saw the child's body on the ground and called 110.
The presiding judge said it was not plausible to believe that Koki unlocked and opened the window and then fell out by accident, Sankei reported.
The court heard that Koki's father had consulted police a week earlier about an incident on Dec 23 when his wife tried to strangle the boy with a cord while at a hotel.
Prosecutors said that Kato initially told police she did not have confidence in her ability to raise a child and that she just wanted to live alone with her husband.
The court also heard that Kato had been shoplifting because she was stressed and that her husband had told her he would divorce her if she ever shoplifted again.© Japan Today
