  • Trace evidence are trace materials that area capable of being transferred to other locations when a crime is taking place (Zhang vol 697). They include glass, human and animal hair, soil, fabric and many others. This type of evidence is transferred from one scene to another by way of contact friction. When something touches the evidence or when it is disbursed by movement. Such type of evidence can help solve a case when it is analyzed and compared to samples collected at the crime scenes. It can help to find out the events that took place or to indicate that a certain individual was present at the scene of the crime (Moenssens 2007).

Fingerprints and Trace Evidence

The primary value of fingerprints as evidence is that they help in identifying any individual’s that were present in a crime scene. Fingerprints leave impressions on surfaces due to the natural secretions of sweat and it is this that forensic analysts collect and use to trace people. Human fingerprints are unique and detailed and very difficult to later and are good for use in human identity. They are related to biometric identifiers because they are an example of the physiological characteristics used in these systems where there is the need to identify individuals that are under surveillance (Blackledge 2007). Two examples of class characteristics include the behavioral characteristics such as ones voice or gait and physiological characteristics which are related to the shape of the body and include palm prints, face recognition, hand geometry and DNA. Individual characteristics include finger prints, retina, DNA which are unique in every human being. Individual characteristics are better because each person is different from the next.
