How was she ritually murdered?
The guy on Coast-to-Coast last night suggested that there is a dark underbelly to the child beauty pagent scene. He suggested that some people who hang around those pagents, including parents, use kids sexually. He said the garrot around the child's neck and the way she was posed with it suggests an S&M scene that got out of hand. He doesn't think the child was killed at the Ramsey house, but her body was brought back and the scene staged to cover up the S&M/child abuse stuff.
Like many other theories of this case, it's a plausible scenario, and it would certainly account for a lot of the peculiar unanswered questions.
