This was part of testimony ? An expert opined this ? What exactly did he say because I am surprised anyone would claim to prove a negative.
There is no evidence there, and the dogs did not track his scent into their home.
One has to use their own judgment, ultimately, to decide whether this is proof.
I would state to you that there could be evidence of a person entering a house, and dogs tracking their scent, and they could have never been in it. Yet, you would accept those things as ABSOLUTE PROOF. Am I right?
I can show you have Danielle's HAIR and DNA got in the MH without her ever entering. But they are being used as PROOF.
At some point you have to accept a negative as proof. And we could argue this till hell freezes over.
The main point is whether there is ABSOLUTE PROOF that Danielle was in the MH on/after 02/01/02, and was taken from there and killed by the operator of the MH, which would be DW.
If the dogs could find a body, alive or dead, why would you use dogs (or testify about using them) ?
My plecostomus didn't detect Danielle's body, and I wasn't called to testify ...
