Michelle Knight made the comments during an interview conducted by a radio host on Sunday at Notre Dame-Cathedral Latin High School in Chardon, Ohio. The (Cleveland) Plain Dealer (http://bit.ly/ZLrDkm ) reports that the 33-year-old Knight, who was kidnapped in August 2002 when she was 21, says she realizes now that Ariel Castro had a disease, and therapy has taught her that what he did hadn't been his fault.
