A 32-year old Saitama woman named Keiko Shinoda was arrested on Friday after she allegedly beat her 3-year old son to death for dirtying his diaper. When questioned by the police, she said:
I lost my temper because he soiled his diaper without saying he wanted to go to the bathroom.
Apparently, she banged his head against the tatami floor until he passed out. He died at the hospital ten hours later. Shinoda has three other children.
