Ligia and her sister Michelle were last seen in Denver, Colorado on March 1, 2002. They are believed to have been abducted by their non-custodial mother. Photographs and information about the mother are unavailable. Ligia and Michelle may be in Mexico. Their father has applied for their return to the United States under the international civil treaty, the Hague Convention on the Civil Aspects of International Child Abduction. The children have not been recovered, however, and their cases are unsolved.
