The article that i read talk about a father who killed his daughter. Miguel Matias living in the Bronx called the police for having killed his daughter. He killed her because she was texting a boy a message and because of the bad behavior of the girl. The father was having some mental problems.The father did not appreciate his daughter having a relationship with boys.

I think that the father is mentally ill as the police said. Since he was already having this problem, they should have kept him in the psychatric hospital to pass the remainder of his life so that the girl would be alive today. It is a bad thing that the father did and people who have this kind of problem should stay in hospital for intensive treatment.
