Waynesville, N.C. -- At least six men came to western North Carolina, some from as far away as South America, to have their genitals mutilated in what police described Friday as a sadomasochistic "dungeon." Three men have been charged with illegal castration in the case, Haywood County Sheriff Tom Alexander and District Attorney Michael Bonfoey said. The sheriff and prosecutor said the victims were willing participants in the procedures. The men met through a Web site produced in North Carolina that published photographs of men engaging in sadomasochistic behavior at a house in Waynesville. . . .
