Pretty good odds, even if Goff is doing the math.
Compare that to no known source for ANY of the fibers, and the high probability that the blue-gray could have come from a vehicle upholstery (like a cop car), spread by one of the investigators from place to place to place as they did the repeated searches. Fibers were collected on several occasions for up to four months (weren't some SUV fibers collected in June?). How can they all possibly be from DAW only considering how many people were at all the sites?
Compare that to no scent or cadaver dogs hitting on either Danielle's scent in the motorhome or SUV OR Westerfield's scent in the VD residence.
Compare that to the huge amount of unexplained evidence that can't be linked to DAW, like the unidentified prints on the VD doors and the bannister and in Danielle's room. And the unidentified DNA on Danielle's bedsheets. And the unidentified prints in the motorhome. And the unidentified red and green and blue fibers on Danielle's body and in her hair and under her nails. And the unidentified black hair found on her body which was not DAW's. And the unidentified hairs from dozens of different people in the motorhome. And the complete and utter lack of ANYTHING of DAW's, fingerprints or hair or scent or DNA or footprints, anywhere near the VD property.
Compare that to the timelines and alibis that keep changing in the VD household. Damon's unsubstantiated and zig-zag trip into the desert on Feb. 16. The mystery dog bed. The disappearing Van Dam Damn Van.
And what are the odds that the jury will collectively possess reasonable doubt? I think some will be stuck on the porn so firmly that no other evidence, all six bug guys included, could sway them from their belief that DAW is guilty beyond a shadow of a doubt.
