The first use of fingerprints in a criminal case occurred in which year?

• A. 1892
• B. 1880
• C. 1877
• D. 1858

Answer: (A)

Fingerprints provide a unique and stable way to identify individuals, making them a powerful tool for solving crimes once reliable methods for collecting and comparing prints were in place. The breakthrough happened in the 1890s. In 1892, inspector Juan Vucetich in Argentina used a fingerprint system to identify a suspect in a murder case, marking the first time fingerprint evidence was used to convict someone in court. This established the precedent for fingerprinting in forensic science and spurred adoption elsewhere in the years that followed. The other dates listed come from times when the method wasn’t yet applied in a criminal case, so 1892 is the earliest year with a documented use in a legal proceeding.
