What must be transmitted when an agency other than the originating agency finds a missing person?

When an agency other than the originating agency finds a missing person, it is necessary to transmit a Locate message. This is because the Locate message serves the specific purpose of indicating that a missing person has been located by an agency that is not the one that initially reported the person as missing. It allows for the proper documentation and communication of the individual's status, ensuring that all relevant agencies are informed and can update their records accordingly.

Using a Locate message is crucial in maintaining accurate information within the NCIC (National Crime Information Center) system, as it facilitates the relaying of important status changes related to missing persons. It also supports law enforcement in coordinating their efforts and ensures that the case can be closed or further processed as necessary. The other types of messages do not fulfill this specific need, as they focus on different aspects of data transmission rather than confirming the location of a missing individual.
