Loads of assumptions. All of which need to be considered in light of physical evidence that puts Danielle in the RV.
According to Testimony, the dogs did not HIT on Danielle's scent in the MH or RV. According to information about tracking dogs, they can detect the scent for up to 2 weeks.
IF Danielle would have been in the MH between 02/01/02 and 02/03/02, the dogs should have detected that. They didn't.
