Crime scene investigation involves the recognition, collection, and analysis of physical, investigative, and forensic evidence in order to reconstruct a scene. Static and large items at a crime scene are processed for fingerprints with various colors of fingerprint powders. Portable evidentiary items should be transported to the laboratory to be processed for fingerprints with chemical reagents in a controlled environment. Burglaries, commercial scenes, and vehicle scenes are frequent crime locations. Productive areas to search for latent prints are the point of entry (POE) and disturbed areas within the scene. As DNA analysis becomes increasingly sensitive and more widely utilized, safeguards must be put in place to avoid contamination.
