Blue Crack Addict
What we came up with was: Since the incident happened here in the US and not Japan, she had to be tried under US law. And a child was definitely intentionally killed. She took the child with her to the ocean and was in her full senses too. So.. we suggested she go to jail for about 10 to 15 years and since the case didn't specify if she was a US citizen, she should be deported back to Japan. But if she was, then jail and probation and counselling. Psychiatric help and all.
I personally would have added mandatory parenting and marriage classes so that she would better know why she was in the wrong which would help in rehabilitation.
