If all of this really happened, she should have been extensively bruised, most obviously on the throat. It doesn't take a lot of pressure to raise bruises there. As for the rest, there should have been a lot of bruising and tears in those areas if this story is true. Some reports I've read said only "swelling"--that wouldn't fit this "dancer's" story.
Here's my theory. She seems to have had sex with anyone who wanted her and/or wanted to pay. She decided she'd get a better payoff by crying rape, especially with (she hoped) well to do and prominent university athletes. This case will probably be lost in criminal court--but watch for a civil suit, hitting the deepest pockets hardest, namely the University.
I think she had sex and didn't want to pay her pimp, probbly the guy who drives her to these things. Once she cried rape, the ball just started rolling and she couldn't stop it. And once she was portrayed as a victim, she didn't want it to stop.
