The sad news in Kagawa prefecture

In Kagawa prefecture, a killed grandmother and two girls are found at the material sheds owned by a realtor. It is revealed the muder is grandmother's young brother-in-law. He said there is money trouble between his sister-in-law and him, but two girls' father denies this fact.

I fell sorry to know the death of two little girls and I cannot understand why two girls had to be killed. Becuase they had not been related to this trouble. Two girls can never be given birth again.

Whenevr I think about their father and mother's feeling, I wonder how sad they feel now.
