The State charged the defendant in a 17-count indictment with aggravated criminal sexual assault, aggravated kidnapping, and aggravated robbery. On February 10, 2000, 22-year-old L.J. worked until 8 p.m. as a cashier at a clothing store in Chicago. On her way home to the south side of the city, she purchased items at the store for her mother and went toward her home. As she passed an alley, the defendant came up behind her and forced her to sit in the backseat of a beige station wagon, where he told her to take her clothes off. The defendant then vaginally penetrated L.J. The defendant also contacted L.J.’s anus with his penis, but did not penetrate. He then pushed L.J. out of the car while keeping L.J.’s coat, money, and other items. After L.J. ran home, her mother opened the door and saw her in tears, partially clothed with only one pant leg on. After L.J. went into the bathroom, her mother called the police. Shortly after 9 p.m., Chicago police officers arrived at the home and found L.J. in the bathtub. She had not yet washed her vaginal area. After L.J. told the officers what had transpired, the officers issued a “flash” message for a black male, 5 foot, 8 inches tall, wearing a black skull cap, a black jacket and driving a beige station wagon. An ambulance transported L.J. and her mother to the emergency room. Whether a state rule of evidence allowing an expert witness to testify about the results of DNA testing performed by non-testifying analysts violates the Confrontation Clause, when the defendant has no opportunity to confront the actual analysts.
