Juan Vucetich developed a unique system in 1891. This system was fingerprint identification. Until then, imprecise methods like signatures were used. His method made it possible to reliably identify people. In 1892, he used it to solve a criminal case. This case was the murder committed by Francisca Rojas. Thanks to its success, his system gained immediate recognition. The police in Argentina began to officially implement it. Soon, other countries also adopted this innovative method. Fingerprints revolutionized justice and criminology. Their system is the foundation of modern forensic science. Currently, fingerprints are essential in global investigations. Vucetich left an influential legacy in justice and security. He is remembered as a global pioneer of criminology. His contribution forever changed personal and legal identification.
