Virginia Makopo, the former dormitory matron at Oprah Winfrey's Leadership Academy in South Africa, pleaded not guilty today to charges that she sexually and physically assaulted six students. The 28-year-old appeared "sullen" as her trial began. According to Starpulse, "Judge Thelma Simpson granted a prosecution request for the rest of the proceedings, expected to last all week, to be closed to the public. She also is allowing the teenagers to testify through close-circuit TV to save them the trauma of confronting their alleged attacker in court. Prosecutor Etienne Venter described the girls as 'very scared and very, very emotional."
