Again, you are correct! The latest talking point is that the search dog did not "hit" on Danielle in the MH. I have stated I do not place much value on dog testimony as a piece of evidence, but as an investigative tool, (this includes the cadaver dog "hitting" on the compartment, too). With that said, those who wish to take the dog not hitting should consider that:
The comforter(s) from the MH were removed and cleaned by the time the dogs entered the MH (I would think she was "kept" on the bed---not walking around freely--speculation) and
Although there was not an overwhelming bleach smell coming from the MH, Westerfield himself told the police that he went out to the MH Monday after their first visit (but first he sat down at his home computer--see his interview with Det. Redden) to "look for his cellphone" and since he was going out there anyway he took his vacuum to do some cleaning.
So perhaps traces of her scent were cleaned up before the dogs entered the MH? Just a thought....
