A 5-year-old Mount Vernon boy who was believed to be kidnapped by his foster parent was found in Vietnam with the woman and her mother. The boy, identified as “ND,” arrived back in Seattle on Friday morning, accompanied by FBI agents and victims’ advocates. The boy reunited with his biological mother after he arrived. "She said that he's doing good, that he was excited to see her," said Brittany Tri, the birth mother's attorney. "They're both excited, so the excitement goes both ways, but she did say that he's very tired." Police say the boy’s foster parent, Amanda Dinges, 35, and her mother, Amber Dinges, 60, kidnapped the boy. Police said now that ND has been found, their focus will be the arrest and extradition of the two women, who are not in custody. Mount Vernon police believe they are in Vietnam, but say international recognition of warrants and extradition is “a complicated process.” The attorney for the boy's birth mother said they had known authorities believed they had left the country, but only found out early this week that he was believed to be in Vietnam.  "She was really shocked to find out that it was that country," said Tri. "She was really, I think it was the first time she was really nervous that maybe they weren't going to be able to find him and bring him back." Tri also said that, to her knowledge, the boy did not have a passport so she is not sure how he was able to get out of the country. The search for the boy began Nov. 28 when Child Protective Services alerted Mount Vernon police that Dinges may have left with the boy.
