Austrian man accused of locking up and raping his two daughters for 41 years

(CBS/AP) VIENNA - Austrian prosecutors are now investigating if an 80-year-old man sexually abused his two mentally disabled daughters for 41 years. However, they said on Friday that no children were born of the alleged incestuous relationships.

The case mirrors that of another Austrian, Josef Fritzel, who imprisoned his daughter in a windowless cellar for 24 years and repeatedly raped her, fathering seven children. Fritzl was sentenced to life in prison two years ago for that crime and for responsibility in the death of one of the children.

The man, from the upper Austrian village of St. Peter am Hart, is suspected of assault, torture or neglect of defenseless individuals, threat to life or physical condition, rape and other sex crimes. He denies the allegations.

He had been living in a senior citizens' home until police detained him Thursday. On Friday, a judge ordered that he remain in custody at least until Sept. 9 pending continued investigations.

The man's daughters, who are now 53 and 45- years-old, have accused him of repeatedly raping them at their home between 1970 and May 2011. The women said their father frequently warned he would kill them if they resisted, occasionally threatening them with firearms and beating them with a stick and pitchfork, police said.

They also said that their mother, who died three years ago, was repeatedly abused by the suspect.

Police have not named the man or his daughters. The nameplate on the family house identifies the owner only as "Wagner."

The women told police that they escaped when their father fell and was unable to get up after the older daughter pushed him during the last attempted rape.
