Alleged `Cybersex' Victim Testifies By SAMUEL MAULL, Associated Press Writer NEW YORK -- A woman who says a graduate student she met online tied her up and raped her in his apartment tearfully described for jurors how she begged, "Don't rape me, don't dismember me, don't kill me" before escaping. In emotional testimony Tuesday, the 22 -year-old woman said she managed to untie herself from a futon, fight off her assailant and flee. "I was sore. I was exhausted. I didn't want to move," she said, then describing how she loosed the cloth strips: "I felt so good! I got it undone and I stood up! I got it undone! I looked at him and he looked frightened! I'm not going to die!" The witness, who said she was naked while tied up, said she grabbed her clothes and got dressed while running for the door and fighting off the man who had held her as a sex captive for more than 20 hours. "He tried to catch me," she said. "I just kept fighting. I wouldn't let him get any part of me. I ran to the door and clenched the handle because I was not going to be tied up again." The woman says her tormentor was Oliver Jovanovic, 31, a Columbia University doctoral candidate in molecular biology whom she met in an Internet chat room. Jovanovic is charged with kidnapping, sodomy, aggravated sex abuse and assault against the woman in his apartment following their first date Nov. 22, 1996. The woman said Jovanovic had tied her up, dripped hot candle wax on her abdomen and genital area, bit her breasts until they bled and used a nightstick to sexually abuse her. The woman said Jovanovic attacked her after a discussion about good and evil and became upset when she said she believes people are not inherently evil. He then ordered her to undress, she said. Defense lawyer Jack Litman said no violence occurred between the two and that any sexual activity, while it might have been unusual, was consensual. He quoted from e-mail messages sent by the woman to Jovanovic before and after their date in which she talks about sadomasochism in what appear to be terms of approval. The e-mail messages the woman sent to Jovanovic included one that reads "Rough is good," and another that reads "I would go through the pleasure of hell's pain." The woman testified that she sought out Jovanovic because she thought he was intelligent, knowledgeable and interesting. Litman called the woman unstable and overly imaginative. He said she is blaming the evening's activity on Jovanovic to absolve herself of something she likes but considers dirty.
