Another problem for the early twenty-first century is that during crime scene investigations, a decision has to be made at an early stage whether to attempt to retrieve fingerprints through the use of developers or whether to swab surfaces in an attempt to salvage material for dna profiling. The two processes are mutually incompatible, as fingerprint developers destroy material that could potentially be used for dna analysis, and swabbing is likely to make fingerprint identification impossible. Forensic fingerprint analysis has been used to identify criminals for more than one hundred years. The process begins with a deposited, or latent, print found at the scene of the crime. Dna profiling (also called dna fingerprinting) is the process of determining an individuals dna characteristics. Dna analysis intended to identify a species, rather than an individual, is called dna barcoding. He studied fingerprint analysis as a forensic science and laid the groundwork for their use in criminal cases. Through his work at an anthropological society, he was able to collect 8,000 sets of prints for analysis. fingerprint analysis provides a way to convict criminals based on hard evidence without dealing directly with more gruesome details often associated with major crimes, like bone and blood dna evidence. Investigators and prosecuting attorneys alike greatly value fingerprint evidence and its ability to sway judges and juries toward a conviction. A new fingerprint technique that has been developed by sheffield hallam university, in partnership with west yorkshire police, could revolutionise how the justice system identifies potential suspects and how admissible evidence can be.
