Andrew Delgadillo and his sister Lourdes Villanueva vanished from San Bernardino, California on December 30, 2006, after their non-custodial mother, Mayra Delgadillo, abducted them. A kidnapping warrant was issued for Mayra on March 21, 2013.

Mayra, who was 22 years old at the time of the abduction, is described as a 5'2 Hispanic woman weighing 150 pounds, with brown hair and brown eyes. A photo of her is available on this case.

Initially, Carlos Ramon Gonzalez and Rose Delgadillo, Andrew and Lourdes' siblings, were also reported missing. However, they are no longer listed as missing. The whereabouts of Mayra, Lourdes, and Andrew remain unknown, and their cases are still unresolved. It is believed that they may be in Mexico, and the authorities are urging anyone with information to come forward.
