Oklahoma City police have arrested a 13-year-old boy in connection with the death of his nine-month-old baby sister after a questionable story of what happened to the child was told to the staff at a metro hospital. ER doctors became suspicious and called the local police. Officers were called to a metro hospital on August 16 after doctors noted that the baby's injuries were not consistent with an explanation given by the girl's parents.

The child was treated at Children's Hospital for a severe brain injury and skull fracture. The 13-year-old, Crystian Rivera told police he was playing a video game when his baby sister fell down and started to cry. Rivera admitted to officers that he became angry and frustrated when his character in the video game he was playing was killed. He apparently shook the girl, according to the police report. He went back to playing his video game as the child cried and eventually fell asleep, he said. Rivera was booked into the Oklahoma County Jail but no charges have been filed yet. The nine-month-old died on Friday from her injuries.
