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

The addition of a 'P' to the message key code is important when a stolen gun is to be held for latent fingerprint examination. This designation indicates that the gun is not only recorded as stolen but also highlights that it is being retained for further forensic evaluation. The designation helps law enforcement agencies to manage and track the status of the firearm through the various databases involved, ensuring that it is recognized as being in a special category due to its potential evidence value. Properly marking the record this way avoids confusion and ensures that all personnel accessing the data understand the specific circumstances surrounding the item.

Other options may serve different purposes related to record-keeping or tracking within the system. However, they do not specifically communicate that the item is being preserved for a latent fingerprint examination.
