In which year and country was the first case of a conviction based on fingerprint evidence?
Fingerprints were first used as evidence in a criminal investigation in 1892 in Necochea, Argentina. During the investigation of the double murder of the two sons of a woman, Francisca Rojas, police interrogated their prime suspect, Rojas' neighbor, but could not extract a confession from him. In the ensuing investigation, the police presented fingerprint evidence to the mother herself, proving her own fingerprints were imprinted in blood at the crime scene, whereupon Rojas confessed to murdering her own two children. . Fingerprints were first used as evidence in a court trial in 1902 in Paris, France, in which Henri-Leon Scheffer was convicted of the murder of Joseph Reibel based, in part, upon evidence of fingerprints left behind on a broken glass case. Scheiffer's fingerprints were deposited upon the glass in such a way, the prosecution successfully argued, that could only be done after the glass was broken, proving Scheffer left behind his fingerprints after the case was broken, and therefore at the scene and time of the murder.
Who invented DNA fingerprints?
Fingerprint evidence and DNA evidence have NOTHING to do with one another except the fact that they are both collected by a crime scene technician.

DNA evidence is concerned with bodily fluids and the unique chemical/biological makeup of them that is unique to all individuals. The only similarity between these two concepts is that both fingerprints and DNA are totally unique to each individual and are, therefore 100% accurate in identifying people.
