A mother gets home to find her infant Mariah’s head lolling from side to side when she holds her in her arms. The mother asks Mariah’s father, who had been looking after the baby, "What happened?!" He says he doesn’t know and that the child was fine when he put her to sleep. The parents rush Mariah to the hospital and, when the doctors examine her, they immediately call the police to investigate.
