'' Winfrey -- who has spoken publicly about abuse she suffered as a child -- became personally involved in the abuse investigation after a student reported the alleged abuse in October 2007 . She cried for half an hour after receiving the call from the CEO of the Oprah Winfrey Leadership Academy for Girls , and she then hired a team of American private investigators to work with South African police on the case , she said . `` I wanted to hire an independent team because my experience with child predators is that no one ever , ever abuses just one child , '' Winfrey said at the time . Despite the verdict , Winfrey said she appreciated the efforts of the prosecutors and police , `` who sought justice and treated the girls with the utmost care and respect . '' `` I will forever be proud of the nine girls who testified with the courage and conviction to be heard , '' Winfrey said . When Winfrey opened the school at the beginning of 2007 , she said she hoped it would provide opportunities to girls from poor backgrounds . She personally approved each of the students , many of whom were at the top of their classes .
