"(CNN) -- Austrian police believe a 73-year-old man held his daughter captive in his cellar for the past two decades and fathered at least six children with her, according to police and state-run news reports Sunday...
Josef F. lived upstairs with his wife, Rosemarie F., who police said had no idea about her husband's other family living in the cellar.
Josef F. and Rosemarie F. had adopted three of the children that he had with his daughter, according to police. He told his wife that his missing daughter had dropped the unwanted children off at the house because she could not take care of them, police said.
The other three children -- Kerstin, 19; Stefan, 18; and Felix, 5 -- remained locked in the basement with their mother, according to police. None had seen the light of day during their entire time in captivity, police said.
