My comment:

If it was the father, the headlines would probably say “Father kills children”. However, Officer’s wife, implies that it was not a mother. Is this a form of bias to protect the title “Mother?” Let me know if I am wrong. Feminism is very sneeky and clever in wording by their own definition of words.
