Austrian officials held a news conference on Tuesday to give further updates on developments of the Amstetten incest case.

Following are some highlights:

Franz Polzer, head of the criminal investigation unit in the province of Lower Austria

ON DNA TESTS

"We have taken and evaluated all the personal traces, all the DNA of all the members in the Fritzl family. The result, which we know now for a few hours, shows that the six children, which the unfortunate Elisabeth Fritzl gave birth to in the basement, have all been undoubtedly fathered by her own father, the now 73-year-old Joseph Fritzl."

Officials said no DNA test had been done at the time of adoption because there was no cause for suspicion. Adoption agency officials had met with the adoptive parents 21 times.

FURTHER BUNKERS

"We have no concrete evidence of this, we have not found anything."

ON DOUBLE LIFE

"This man led a double life. Not only an official life upstairs, but a double life downstairs."

STORE ROOM

Asked how the cellar family was fed when Fritzl apparently spent extended periods on holiday in Thailand, Polzer said there was a store room that could have been used for food.

"It could have contained enough for weeks."

ROSEMARIE

"There is no evidence that she was involved also it defies logic that a mother of seven children would help the captor of her daughter."

Berthold Kepplinger, medical director of the Provincial Clinic of Lower Austria

ON THE CHILDREN

"(All) the children are quite well. They met each other on Sunday morning and it is astonishing how easily it worked that the children came together."

"Also, it was astonishing how easy it happened that the grandmother and the mother came together."

Kepplinger added, the clinic had a school where the children could be educated as their treatment and recovery progress."

"They can read and write in a somewhat reduced form."

Hanz-Heinze Lenze, senior local official

"Steps such as taking a new identity (for the victims in the cellar) will be discussed in the coming days and weeks."
