Which of the following is required for a gun to be entered into NCIC as stolen?

For a gun to be entered into the National Crime Information Center (NCIC) as stolen, a theft report must exist. This requirement ensures that there is an official record of the theft that can be verified. Having a formal report allows law enforcement agencies to track stolen firearms effectively and contributes to the overall integrity of the data within the NCIC.

The existence of a theft report not only verifies that the firearm was indeed stolen but also provides essential details about the incident, including descriptions of the weapon and circumstances surrounding the theft. This documentation is critical for law enforcement agencies as they investigate crimes and work to recover stolen property.

Other options do not meet the necessary criteria for entering stolen firearms into NCIC. While details like the model number may be helpful, they are insufficient on their own without the foundational support of a theft report. Similarly, personal records or proof of purchase may assist the owner in proving ownership or facilitating recovery, but they do not fulfill the requirement to document the theft in the first place.
