Fingerprints
1. The study of fingerprints is the best means available for identifying individuals. Fingerprinting is a simple and inexpensive means of recording an unchanging characteristic of an individual. Fingerprint records are consulted to determine if there is any prior criminal record. They help in determining the identity of the dead or injured.
2. Fingerprints are perhaps the most common form of physical evidence and certainly one of the most valuable. They relate directly to the final aim of every criminal investigation – the identification of an offender. Fingerprints of the offender are often found at the scene of a crime. However, the prints can be easily destroyed by the first careless act. They are also, in many cases, difficult to find, especially latent prints.
3. So it is necessary that the crime investigator make a thorough search of all surfaces in and around the scene of a crime. Particular attention should be paid to such places as the backs of chairs, table tops, telephone, etc. Valuable help in obtaining latent prints may be given from a person who knows the usual layout of the crime scene. He may point out articles that are out of place or identify objects that may have been brought in by the criminal. The possibility that the weapons of science can be turned against itself by the forging of fingerprints cannot be ignored.
