The mystery is solved — but the future of the young girl known only as Maria is still uncertain.

DNA tests have confirmed that a Bulgarian Roma couple living in an impoverished village with their nine other children are the biological parents of the girl found in Greece with another Roma couple.

Genetic profiles of Sasha Ruseva, 35, and her 37-year-old husband, Atanas, matched that of Maria, Bulgarian Interior Ministry official Svetlozar Lazarov said Friday.

By late Friday, the couple had not returned to their home that was surrounded by local and international reporters after the news was announced, and police said their whereabouts were unknown to them.

Three of the couple’s youngest children were taken to a shelter for temporary care, said Diana Kaneva, director of social services for the central Stara Zagora region.

Ruseva had said she gave birth to a baby girl four years ago in Greece while working there as an olive picker but gave the child up because she was too poor to care for her. She had two more children after Maria.

Maria has been in a charity’s care since authorities raided a settlement of Roma, also known as Gypsies, in Greece last week and found she was not related to the Greek Roma couple she was living with.

Her discovery triggered a global search for her parents, fears of possible child trafficking and interest from authorities dealing with missing children cases in Poland, France, the United States and elsewhere.

Human rights groups also have raised concerns that the news coverage about Maria and the actions taken by authorities were fueling racist sentiment against the European Union’s Gypsy minority, who number around 6 million.

The Bulgarian prosecutor’s office and Greek authorities were “seeking clarification on whether the mother agreed to sell the child,” the Interior Ministry said in a statement.

It wasn’t clear if Maria had been told who her real parents are. The Greek charity Smile of the Child, which has been looking after her, would not comment on the case.

Social services director Kaneva, after visiting the Ruseva home, said the child would likely be returned to Bulgaria for adoption.

The Rusevs and their other children live in a dilapidated, mud-floored house outside the remote Bulgarian town of Nikolaevo, 175 miles east of the capital, Sofia.

The Roma quarter in the town houses about 2,000 people. Most are jobless, living in extreme poverty, trying to stay warm in shabby houses. Children played Friday in mud-covered streets as pigs, cats and hens ambled by.

Minka Ruseva, the 14-year-old daughter of the Bulgarian couple, stood in front of their dilapidated two-room house. Minka said she saw pictures of Maria on TV and thought she was her sister.

“I like her very much. She looks very much like me, and I want her back home. We will take care of her, and I can help my mother,” she said.

Greek officials, fearing that Maria’s 2009 birth record contained false information, have ordered a nationwide check of all Greek birth records in the past six years to ferret out welfare fraud or other irregularities.

The Greek Roma couple, now in pretrial detention, have been charged with abducting Maria and committing document fraud. They told authorities they received Maria after an informal adoption, and their lawyer said Friday they planned to seek legal custody of the girl.

Under Greek law, child abduction charges can include cases where a minor is voluntarily given away by its parents.
