What should be added to the message key code if a stolen gun record is to be held for latent fingerprint examination?

• A. A
• B. B
• C. P
• D. Q

Answer: (C)

The correct choice for adding to the message key code when a stolen gun record is to be held for latent fingerprint examination is P. This designation indicates that the record is not just a standard stolen property record; it includes specifications about the examination of latent fingerprints, which is critical for forensic purposes.

By using the P code, law enforcement agencies ensure that this particular stolen gun record is flagged for further investigation, specifically regarding any latent fingerprints that may be present. This alerts those accessing the record that additional forensic procedures are to be followed, which is essential in the investigation of firearm-related crimes.

Other options do not signify this particular aspect of holding the record for latent fingerprint examination, and therefore, would not fulfill the requirement needed for tracking and investigation in the context of forensic analysis.
