Nadia disappeared from Cary, North Carolina on February 3, 2009. She was abducted by her non-custodial mother, Larissa Melo Drummond. Photographs and vital statistics for Larissa are posted below this case summary. A felony warrant was issued for her on February 17, 2009.

According to Nadia's father, Devon Davenport, Larissa threatened to take the baby to Brazil shortly after her birth. Larissa had been born there. She had custody of Nadia and they lived in the 100 block of Woodruff Court. Davenport was given visitation, but he stated Larissa consistently ignored the visitation schedule. Nadia was not be taken out of North Carolina without permission from the court, and Larissa was ordered to surrender the child's passport. She said Nadia did not have a passport. After Nadia's abduction it was determined that Larissa had in fact gotten a passport for Nadia shortly after she was born, and used it when she abducted her. Both parents' signatures are required to obtain a passport for a child, but Larissa was able to circumvent this rule because she did not list Davenport as the father on Nadia's birth certificate.

Larissa took Nadia to Brazil after the abduction. They arrived on February 5, then disappeared again. Davenport was given sole legal and physical custody of Nadia after she was taken and filed for her return to the United States under the terms of the Hague Convention on the Civil Aspects of International Child Abduction. Brazilian authorities accepted his application, but they cannot enforce the treaty until they can locate Nadia and her mother. The child's whereabouts are unknown and her case remains unsolved.
