"Why would Adam Barney kill a newborn baby?"

I watched a story on the channel 13 News about a man named Adam Barney was arrested for the murder of the fourteenth month-old baby girl named k.c who recently lost her life a month ago by the mother's live-in boyfriend, only the mother was not aware that he was abusive to that child when he was alone with baby, squeezing the baby, hitting her in the face twice and the worst punching her in the stomach that caused her death. When a child is brought into this world a child has a commitment to the parents as well as the parents have the commitment to their children and to help them and to guide them to help them find their own way's in life, remember the fact that Adam Barney stole the life of that fourteenth month-old baby girl and how her life was taken away to soon and if he gets away with murder the justice would go unaswered and answer it now for the sake of the fourteenth month-old baby girl.
