So...That would have required more than a tiny bit of fluid-Not only for it to be left on the bag like that, but to completely saturate that board. To clean that trunk thoroughly would have taken more than a handful of paper towels. And it had to have been cleaned, because the black light was not exactly exposing heavy pools and splotches everywhere.
Whichever Anthony cleaned that trunk then had to have seen the color, smelled the fluid in the wet vac, or on the towel they cleaned with. CA is a nurse. GA indicted the circle stain smelled horrfying.
How? Granparents? There was never a chance to get CA on the side of LE, she made a firm decision and acted on it, it was too late to go back once she cleaned her grandaughter's bodily fluids, washed the odor from KC's pants, etc.
ETA-I know some have pointed out that no cleaning solutions (soaps) were found by the labs-CA could easily just have used water and gotten the same effect-Maybe they did not have carpet cleaner in the house, or she did not have time to make a solution. While surfactants help to carry dirt to the surface, water would have worked seemingly well enough, would have brought a lot of the fluid back to the surface. And unless they had a powerful/commercial shop vac, some of the water she put down would not have come back up and would have settled down to the board below.
