A 15-year boy in Yokohama, Japan turned himself in to police this week after stabbing his mother and grandmother to death because they asked him to do his homework.
According to local police, the boy walked into their booth on Monday, brought out a bloody knife from his bag, and confessed that he had just killed his 50-year old mom and 81-year old grandma. Police went over to his house, where they found their bodies lying on the floor with multiple stab wounds.
The boy reportedly told police that he killed them out of anger because they were always scolding him for not doing his homework.
Police say the boy had been living with his mom, grandma and 12-year old sister, who had been in school as at the time of the stabbing.
