Latent Fingerprint: A Comprehensive Guide to Its Legal Definition

Definition & Meaning

A latent fingerprint is an impression left on a surface by the natural oils and sweat from a person's fingers. These fingerprints are typically not visible to the naked eye but can be revealed using specialized techniques. Common methods for detecting latent fingerprints include dusting with fine powder and lifting the print with transparent tape. Additionally, lasers can be used to illuminate certain fingerprints, making them easier to photograph and analyze.
