What should be added in the AKA field of a missing child record according to NCIC recommendations?

In the context of the NCIC recommendations for entering information into the AKA (also known as "also known as") field of a missing child record, the inclusion of the mother's maiden name is relevant for identification purposes. The AKA field is intended to capture any names that a missing child might be known by, which can include familial connections.

By adding the mother’s maiden name, investigators and law enforcement personnel can cross-reference this information more effectively with various databases and records. This connection can be particularly useful in cases where the child may have been known by a different surname due to family changes, custody situations, or other circumstances.

The other options do not fit as appropriately in the AKA field. While a child's middle name, father's name, or social security number may provide valuable information in different fields within a record, they do not serve the same purpose as the maternal surname in establishing alternate identities or references specifically related to familial ties, which is the intent of the AKA field in this context.
