Which two categories are mandatory for entering missing persons into the NCIC?

The correct answer focuses on the specific requirements for entering missing persons into the NCIC system. The mandatory categories for entering missing persons include specific data points that pertain to the case rather than general descriptors or broader classifications.

When entering a missing person into NCIC, it's crucial to include the appropriate identifiers from the specified categories of HDR (Human Data Record), MKE (Make), ORI (Originating Agency Identifier), and NAM (Name). These elements are essential for properly documenting the case and ensuring that the information is accessible and organized for law enforcement agencies.

The answer highlighting the necessity of any two from HDR, MKE, ORI, or NAM emphasizes the focus on key identifiers that will assist in effectively tracking and managing missing person cases within the system. Each of these categories plays a pivotal role in linking cases to relevant databases and in facilitating communications between agencies.

The other options, while they may mention relevant categories, do not correctly identify the mandates that specifically pertain to the entry process within the NCIC framework. Therefore, the emphasis on the importance of accurate data entry from established categories underscores the operational efficacy of the NCIC in managing missing persons cases.
