Why is it important to include a diagram on a latent print card?

Including a diagram on a latent print card is crucial because it details the specific location of the latent prints found at a crime scene. This information serves several important purposes. Firstly, it allows investigators to understand exactly where each print was located in relation to the overall crime scene, which can provide context regarding the circumstances of the crime. Secondly, it aids in maintaining the chain of evidence; if the prints are referenced in terms of a specific location, it becomes easier to link them to suspects or other pieces of evidence later on. Additionally, having a clear diagram supports efficient evidence processing and can assist in courtroom presentations by visually illustrating critical aspects of the investigation.
