Introduction: The Uniqueness and Persistence of Fingerprints

Fingerprints have long been heralded as infallible markers of individual identity, their unique patterns remaining unchanged throughout a person's life. This permanence makes them invaluable in forensic investigations and personal identification. However, the reliability of fingerprints can be compromised after death due to various physiological and environmental factors. Understanding these challenges is crucial for forensic experts tasked with postmortem identifications.

The Immediate Aftermath: Changes in Skin Properties

Upon death, the human body undergoes a series of transformations that begin almost immediately. One of the first changes is the loss of electrical charge in cells. This loss affects the skin's conductivity, rendering fingerprint sensors, such as those on smartphones, ineffective. Devices relying on capacitive touch require this electrical charge to function, and without it, even a recently deceased individual's fingerprint cannot unlock such devices. ...Read More
