Kids sometimes tell fantastical stories. But when children are victims of abuse or witnesses to crimes, separating truth from fantasy in their stories can be a major challenge for police.

Charlie spoke to a West Valley City police detective at the Salt Lake County Children’s Justice Center the following day. The story Charlie told proved both incriminating for his father and inscrutable to investigators.
