A German trucker on trial for 350 counts of sexual abuse of his children has admitted in court that he fathered his stepdaughter's 8 children—but insists he never abused her. The 48-year-old father, known as Detlef S., began sexually abusing his stepdaughter and her twin brother at the age of 4, reports CBS News. He also repeatedly assaulted his biological daughter, and prostituted both girls for money, according to investigators. He often beat the children with a belt and whip, sometimes until they lost consciousness, notes Der Spiegel. (More incest stories.)
