Lourdes Jesus Villanueva was just 1 year old when she disappeared from San Bernardino, California, on December 30, 2006. She was abducted along with her 4-year-old brother, Andrew Delgadillo, by their non-custodial mother, Mayra Alejandra Delgadillo, who was 22 at the time.

A felony warrant for Mayra was issued in March 2013, and she has been wanted for kidnapping since then. Authorities believe Mayra may have fled to Mexico with Lourdes and Andrew. Two other children who initially went missing with them, Rose Delgadillo and Carlos Ramon Gonzalez, are no longer listed as missing.

Whereabouts of Lourdes, Andrew, and Mayra remain unknown; anyone with information is asked to contact the San Bernardino District Attorney’s Office.
