On April 29, 2002, in the small town of Pataskala, Ohio, a social worker sat on the floor with a two-year-old girl. The little girl's mother had been murdered in their kitchen the night before, and police thought she might have witnessed the crime. The girl clutched a stuffed animal to her chest while the social worker asked her if anyone else had been in her house the night before. The girl nodded – and uttered a name that would turn her family's lives upside down.
