" In other words she said Natalee was raped and there should be DNA evidence in her son's car."
She sure seemed to imply that is what she was told by the sons. However, that was the story they told her, before they changed it to--> We dropped Juran and Natalee at the beach. So who knows if what the sons told her was true or not.
I thought they tested the "bloodstain" in the backseat...surely they ruled out semen when they ruled out blood?
