She probably had sex, maybe rough sex before arriving at the house. When she passed out and the cops arrived, she could have feared being charged with drug possession or who knows what...loss of her children if jailed, kicked out of college, any number of things. She could have thought, well, I'll claim I was drugged and raped by these white guys. Shift the blame. In the meantime the story grew to be huge, and you can bet some lawyer's said, I'll get you a boatload of money, honey. Just sit tight. (Even if they're are found not guilty, we can sue for damages in civil court. Sue Duke, too. They've got more money than you can shake a stick at! Whoo Hoow!)
I've screwed up the time line, but the premise could be true. That she had sex before arriving and then later. Perhaps was raped after leaving the party. If she has a pimp, he could have raped and beaten her for not getting enough money. No DNA from the players, so she definitely had sex with someone else. Whatever, there's no case against the players except name calling and even that's problematical. Now that Jesse's involved, it's too late for her to admit the truth.
I remember hearing the hospital did not do a tox screen on her, which I thought really odd. I mean you come into the ER looking like hell and say you were raped, surely they would want to make sure you weren't drugged as well. And DNA can come from hair, skin and saliva, not just sperm yet they can't find a trace of anything on her. She showed up hammered, she was partying somewhere before, who was she with?
