Abstract
Forensic laboratory techniques that are utilized to identify potential evidence for collection and preservation are what is needed to solve cases and present evidence in court. When a crime has been committed the crime scene will always have evidence that must be collected and tested in order to identify victims, suspects, and to further explain what transpired at the crime scene. There is always a different way of collecting the potential evidence as the evidence located at the crime scene varies. Methods to carefully collect and preserve the evidence must be adhered to at all times as so not to contaminate the evidence collected. There are several types of evidence that can be collected at a crime scene that can be contaminated such as depositing hairs or fibers from clothing, latent footwear and fingerprints and DNA from another source that may be relevant to the case. There are also various search types that are utilized to search a wide array of crime scenes. Crime scene search methods are based on the type of evidence, location and the size of the crime scene. These various search methods are link, line or strip method, grid method, zone method, wheel or ray method and the spiral method. The aim of this research is to explain and show how forensic laboratory techniques are utilized to identify potential evidence for collection and preservation.
