Karla Kassandra Pineda-Hernandez was 10 years old when she was last seen in Pacoima, California, on September 14, 2006. She vanished along with her three younger siblings, then ages 2, 3, and 7. Authorities treat the case as a family abduction by the children’s non-custodial mother and suspect they may have been taken to Mexico.

At the time she disappeared Karla was about 4 feet tall, weighed approximately 75 pounds, and had brown hair and brown eyes. Efforts to locate the children have included applications under the Hague Convention on the Civil Aspects of International Child Abduction, but no conclusive information about their whereabouts has been reported and there have been few updates.

Anyone who knew Karla or her siblings, saw them around September 14, 2006, or has information that could help locate them is asked to come forward.
