The fingerprint is direct evidence she was in the MH. It does not tell us when she was there or that she was murdered or held prisoner there. We know she was in DW's house. We know the MH was often parked very close to Danielle's house where she was allowed to walk and play. In my book, that is reasonable doubt.
I think DW might have done it. But it has not been proven beyond a resonable doubt -- yet.
The sad thing is, we may never know who did it.
I still think the "dog scratch" incident at the park will come into play for the defense. IF she got scratched by the dog at the park AND DW put a band-aid on it for her, then this case is closed.
