"Chicago woman identified by prosecutors as an escort testified Thursday that she was raped by a former boyfriend after he used a fake identity to evade her online screening process and then showed up at her home in a disguise that included a beard, dark makeup, sunglasses and a turban...Testifying at a preliminary hearing at the Leighton Criminal Court Building, the woman, 26, said she didn't realize the attacker was ex-boyfriend Nathan Nissenbaum until his sunglasses fell off while he restrained her with handcuffs and duct tape before the sexual assault.'
