The judge said that the balance of probabilities was that he took her pants off because they were inside out.  I've taken my own pants off inside out before, it doesn't mean anything, especially if she was struggling so hard to take them off that she pulled up her shirt, dropped her phone and ended up with her shoes and purse in the front seat.  He also said that the balance of probabilities was that he had inadvertently touched his lip after touching her urine soaked pants resulting in her DNA being on his upper lip.  His DNA was not found on her, the judge said that the evidence was troubling but it really doesn't add up to anything.
