When dealing with evidence, which form is used to document an evidence tag?

The proper form used to document an evidence tag is AF Form 52. This form is specifically designated for tracking and recording evidence collected during investigations, ensuring that all details are meticulously noted for proper chain of custody, which is crucial in maintaining the integrity of the evidence.

AF Form 52 includes sections for pertinent information such as the date collected, the location, a description of the evidence, and the collector's information, all of which are vital for legal proceedings. Using this standardized form helps ensure consistency in how evidence is documented across different cases and investigations, supporting effective record-keeping and maintaining a reliable chain of custody.

The other forms mentioned serve different purposes. For instance, AF Form 75 is primarily used for visitor register logs, AF Form 1109 serves as a visitor pass log, and AF Form 1168 is typically used for statements from witnesses or suspects. Each of these forms has its specific function, but they are not intended for documenting evidence in the same comprehensive manner as AF Form 52.
