LEWISBURG, Tenn. -- A woman who ended her adoption of a 7-year-old Russian boy by putting him on a plane to Moscow by himself lost her bid Friday to keep from paying $150,000 in child support.

Torry Hansen made her first court appearance Friday in a case that began in April 2010 when she sent Artyom Saveliev away from her home with a letter that said he had violent behaviour problems and she no longer wanted to be his mother.

Criminal charges were never filed but the Seattle-based adoption agency she used, the World Association for Children and Parents, sued her last year for child support.

Hansen, who now lives in California, went through a string of lawyers as she contested the child support and never responded to summonses to appear in court or at depositions. After Circuit Court Judge Lee Russell ordered her in May to pay $150,000 in child support, she hired a new attorney, former federal prosecutor Edward Yarbrough of Nashville.

In court on Friday, Hansen told the judge her previous attorneys did not keep her informed about the case and advised her she did not need to come to court. She also said that she gave birth to a daughter last year and could not come to court because of the pregnancy.

Hansen never spoke to the media before Friday, but her mother, Nancy Hansen, told The Associated Press in 2010 that her daughter, then 33, had to return the boy when he developed serious behaviour problems. Nancy Hansen claimed he hit, screamed and spit at his adoptive mother and threatened to burn down the Hansen home and kill members of the family.

"Without going into depth, I can say he was very violent. I can say he wanted to kill me and he tried to kill my sister," Torry Hansen said in court Friday.

She said that the boy threatened to stab her mother to death. She started to tear up when describing how the threats of violence sent her mother to the emergency room in Shelbyville.

"That was when my parents decided to take him, because he was so violent," she said.

She said it was her parents' decision to put the boy on a flight to Russia, but she was aware of the decision and acquiesced.

"I have never mistreated or abused him or any child," she said.

Under cross examination, Torry Hansen told the court that she never called the police or the state Department of Children's Services about his behaviour.

"I called numerous psychologists and was told there would be a 6-week wait to get in," she said.

When asked whether she was aware that a Russian court found that her actions constituted neglect and abuse, she said, "I am aware that they felt putting him on the plane was emotionally disturbing."

Ruling from the bench, Judge Russell upheld his default judgment against Hansen, ordering her to pay child support for Artyom, who now lives in a group home in a Moscow suburb. Russell said Hansen had not co-operated with the court and he wasn't convinced by her arguments.

Yarbrough said Hansen has been making the child-support payments and will be required to continue doing so.

The case contributed to a decision by Russia in 2010 to delay some adoptions by U.S. parents. Russia on Monday ratified a new agreement with the United States that gives the country greater power to regulate international adoptions.

After the judge's ruling, Yarbrough said the litigation is not over and his client still has options, such as appealing the order or requesting that it be modified.

"I think it is a loss, we wanted the judge to set aside the default judgment and have a full trial, but there are other options for us," he said.

The attorney for the adoption agency, Larry Crain, said the child spent six weeks in a psychiatric hospital when he was returned to Russia because of the trauma he experienced.

He said the case has had huge implications on international child adoptions, as well as sparked outrage in both countries.

"I believe even the accord last week was due to the fact that finally this court, when no one else would step up and do anything for this child, finally this court did ..., " he said. "Now we believe there are safeguards in place to prevent this from ever happening again."
