All Fingerprint and Biometric Identification

Landmark cases whose defining forensic significance is the use of fingerprint or other biometric matching to identify the offender, from the first homicide conviction secured by fingerprint evidence in 1892 through a case solved via an early automated fingerprint identification system search decades later. Belongs here: a case whose historical importance rests specifically on a biometric matching breakthrough. Does not belong here: a case identified through DNA rather than fingerprint evidence, grouped under DNA and Genetic Identification, even though both are biometric methods in the broad sense; this tree keeps them separate because they represent two distinct historical eras and techniques of forensic identification.
