BALTIMORE (AP) _ Advocates for sexual assault survivors are worried the discredited account of an alleged gang rape at the University of Virginia may have a chilling effect. A Rolling Stone article about a student identified as “Jackie” described an alleged rape on campus and a culture of binge-drinking and looking the other way when students filed sexual assault complaints. On Monday, Charlottesville Police Chief Timothy Longo said an investigation turned up no evidence of a sexual assault, or any wrongdoing by the school. Daniel Carter has been a sex assault victim advocate for more than two decades. He says the discredited story may deter victims from coming forward, but progress has been made and he hopes it will continue.
