What does a Query Unidentified Person (QU) require as mandatory fields?

A Query Unidentified Person (QU) requires comprehensive identifying information to help law enforcement accurately and efficiently identify individuals. The correct answer includes age, sex, race, eye color, hair color, height, and weight. This set of mandatory fields is crucial because each characteristic adds to the overall description of an unidentified person, which can significantly assist in identification processes.

Having complete details such as eye color and hair color, in addition to the basic demographic information, enhances the ability of law enforcement agencies to match descriptions with individuals in their databases or with missing person reports. In many scenarios, the accuracy and thoroughness of the information can make a substantial difference in resolving cases.

The other options do not provide the necessary level of detail required for effective querying and identification. For instance, limiting the information to only name and age or to age and height significantly reduces the potential for identification and could lead to misidentification if multiple individuals share similar characteristics. Hence, the comprehensive list in the correct answer is essential for effective law enforcement inquiries related to unidentified persons.
