A RUSSIAN ORPHAN ADOPTED BY AN AMERICAN MAN SPEAKS OUT FOR FIRST TIME ABOUT BEING MOLESTED BY HER ADOPTIVE FATHER � WHO POSTED EXPLICIT PHOTOGRAPHS OF THE LITTLE GIRL ONLINE -- ON ABC NEWS� �PRIMETIME,� THURSDAY, DECEMBER 1,

What You Need To Know When Taking a Train That Might Save Your Life

Pictures of a skinny little girl, tied up and raped, became a popular visual in cyberspace for pedophiles � but no one knew who the little girl was nor who the sick person was taking and posting the photos. For five years police helplessly watched this girl grow older on the internet, as new photos were posted. Finally, police were able to track down the pedophile responsible for tormenting this little girl � a girl named Masha. For the first time ever, Masha, a Russian orphan adopted at age five by Mathew Mancuso, a 41-year-old divorced, wealthy American, speaks out about her trip to hell and back. John Qui�ones� exclusive report, which includes how the photos helped detectives rescue Masha, airs on �Primetime,� THURSDAY, DECEMBER 1 (10:00-11:00 p.m., ET) on the ABC Television Network.

The report chronicles Masha�s adoption from an orphanage in a small industrial city in the south of Russia to her new home in the outskirts of Pittsburgh, PA, and questions whether anything could have prevented the vicious child abuse -- questioning whether there was any post-placement supervisor, and why Mancuso�s ex-wife and grown daughter were never interviewed about why he was estranged from his biological daughter. The latter could have exposed the claims of his biological daughter � that she, too, was sexually abused as a child.

Masha, who has since been adopted by another family, says she is speaking out now at the age of 13 �because I think that it�s wrong, what he did. And this is happening so often now. And a lot of times nobody ever tells anybody� Some kids just give up. And they don�t have any faith.�

Mancuso was sentenced to a minimum of 35 years in prison, on top of 15 year federal sentence, and could face life in prison in Florida for the crimes he committed in a rented room at a Disney World hotel.
