According to the dad, his daughter was staying with her grandmother, not with her mom, so they didn't even tell him when that changed.

The probable cause statement is very depressing. Is that the same as a confession? It sounds like they don't have to wait to find out whose body they found because she told them. Also, "object" with the clothes was a doll dressed in the clothes so it sounds like the plan was to make people at the park think they'd seen a little girl in those clothes.
