Police in Houston are looking for a man who's accused of firing shots into a car and killing a baby girl -- who was said to be his own daughter. The body of four-month-old Brianna Battle was found dumped in a parking lot. Police allege the baby's mother and her boyfriend got into a fight while they were going through a car wash on Friday. They say the man started shooting into the back seat, where the mother, the victim and a two-year-old child were sitting. The older child was not hurt. The name of the boyfriend -- identified by the mother as the father of the slain girl -- has not been released. Child welfare authorities say the baby was with her mother in violation of a court order. She was only allowed supervised visits with her children because of alleged drug use.
