Mystery girl 'Maria' draws 8000 calls Greek police are investigating the identity of "Maria" on suspicion she may have been abducted from her parents. The discovery of what appears to be a missing four-year-old girl in a Gypsy camp in Greece has drawn more than 8000 calls from people around the world seeking to return her to her legitimate family, the charity caring for the girl told CNN. "At least eight calls have some information that can be used by the police for further investigation," said Panagiotis Pardalis, spokesman for the group Smile of the Child. Four of those calls came from the US, he told CNN. The blonde, blue-eyed girl is thought to have been abducted after she was found in squalid conditions with a couple and 13 other children at a camp near Farsala in central Greece. DNA testing on the girl and the couple posing as her parents showed they were not related. A Roma woman walks next to the house where "Maria" lived in Farsala, central Greece. Mr Pardalis said the girl, called "Maria," is "at peace" and is doing "much better" than when she was found. Her discovery has raised hopes for families of missing children. The sister of a child who went missing in Greece more than 20 years ago said she wanted her own DNA to be tested against Maria's on the off chance the girl is related to her missing brother.

His sister Leighanna Needham, 20, never met Ben but says the discovery of Maria is welcome news for her family's fight for answers. Obviously, it's been a strong belief of myself and all my family that Ben was taken by Gypsies for child trafficking or illegal adoptions and this case just shows that they can be found. The couple she was living with at the camp, a 39-year-old man and 40-year-old woman, have been taken into custody and charged with child abduction. Needham says DNA technology could help find her long-lost brother. "I think that would be a brilliant thing to get our DNA out there, even if it's not actually Ben but any siblings or any children maybe of Ben [that are found] then that could hopefully lead us to him," she said. Madeleine vanished from a holiday apartment in Praia da Luz, Portugal, in 2007, when she was three. Clarence Mitchell, a spokesman for parents Kate and Gerry McCann, said Maria had renewed their hope that Madeleine would also be found. Maria's discovery comes days after renewed interest in Madeleine's case across the UK and Europe following a BBC Crimewatch episode that aired a week ago showing two new e-fits of a suspect.
