What information is commonly recommended to include on the back of a latent print card?

Including a small diagram of the location of latent prints on the back of a latent print card is highly recommended. This diagram not only helps in visualizing the specific areas where prints were recovered but also provides critical contextual information that can be crucial during the analysis and examination process. It aids investigators and analysts in understanding how the prints might relate to scene dynamics, such as the positioning of potential witnesses or the movement of individuals involved in the incident.

This visual representation can enhance communication among team members and can serve as a valuable reference during subsequent investigations or court proceedings. It situates the latent prints within the broader narrative of the crime scene, thereby reinforcing the connection between the evidence and the scene itself.

The other options, while they contain some relevant information, do not provide the same level of contextual understanding or visualization that a diagram offers. For instance, including names or personnel numbers could be useful for record-keeping, but it does not enhance the understanding of the print's significance in relation to the crime scene. Similarly, while listing individuals present at the scene or recording the date and time can be important details, they lack the spatial relevance that a diagram provides, which is essential for effectively interpreting the evidence associated with latent prints.
