Naturally you would explain this story and it would check out since the child's parent, for example, would support your story.
Relax, you'll be OK-----if you're innocent, that is.
And you know DW didn't tell the police how she might have gotten in there, how?
And if this parent is a lier like BVD or has an agenda, then what?
The point was that a single small drop of blood doesn't prove a thing, and children do often bleed from small cuts.
The child could have easily spent a few moments, unattended and unnoticed, in the motor home on some occasion, and dropped a bit of blood.
I suppose you have an explanation for the fact that the dogs did not hit on Danielle being in the MH, but did hit on her being in the home (ie, Feb 1st)? Obviously he would have had to transport her dead body in it in his winding travels...
