latent print development

Latent print development is a process used by forensic experts to make invisible fingerprints visible. When a person touches surfaces, oils, sweat, and other residues leave a tiny, invisible print. To see these prints, specialists apply techniques such as powders, chemicals, or special lighting that react with the residues, revealing the unique ridge patterns of the fingerprint. This process helps investigators identify individuals and link them to specific locations or objects, playing a crucial role in criminal investigations.
