How Crime Scene Investigation Works

The first Forensic Research Institute in the United States opened in Los Angeles in 1923. In 1932, the FBI established its own forensic research institute to provide services to police stations nationwide and other research organizations. FBI Labs is one of the world's largest laboratories.

The Denver Crime Institute at the Colorado State Investigation Authority provides evidence collection and laboratory analysis for every police station in Colorado that requires it to serve. We also conduct surveys of states that are not under jurisdiction of local governments.

The special department of the Denver Criminal Research Institute has an automated fingerprinting system (AFIS using the FBI database), which analyzes and compares the impression of potential fingerprints and impressions, fingerprints, footwear, and tires to generate potential fingerprints, Includes fingerprint execution by. Compare with hundreds of millions of prints

Track evidence department for GSR analysis to identify and compare soil, glass, fiber and paint samples. The chemical department analyzes and compares illegal drugs, explosives and unknown chemicals. The computer crime team regains evidence from the computer and computer- enhanced voice or video evidence. There are also identification and comparison of gun and tool identification to identify guns, gun test to determine barrel mode and distance between muzzle and entrance wounds, and impression of bullets, casing and tool markings. Serology and DNA for body fluid analysis including hematological staining, DNA analysis of semen and hair, identification, comparison

Finally, there is a question file section that detects counterfeiting and changes, performs handwritten comparisons, rebuilds corrupted files, and identifies and compares printers, typewriters, or copiers used to generate documents .

Usually one evidence is analyzed by several departments. Each department provides a complete case study report, including actual results (figures, measurements, chemical composition), and expert conclusions led by scientists from these results. Responsible CSI can deliver the results to the case's main detective, or the laboratory can send the results directly to the detective team.

A Criminal Investigator (CSI), including evidence technicians, crime scene analysts, or forensic investigators, is responsible for identifying, collecting and recording the physical evidence found at the crime scene. Investigation of crime scenes and research in forensic laboratory requires a highly educated individual with a background in forensic medicine, natural science and criminal justice system. Most law enforcement agencies and forensic laboratories require that job seekers obtain an associate degree or a bachelor's degree. Those who are interested in this series of work can acquire degrees or certificates through vocational schools; however most people are in the criminal justice department that provides a degree focused on forensic and crime scene surveys I seek education through a school.

Technicians are practical tools in the field of forensic medicine. They will help gather evidence, conduct behavior analysis, and investigate crime scenes. Forensic science and technology personnel are often referred to as criminal engineers or crime scene investigators who do most work in the field or laboratory. Blood group analysts are often called blood splatter experts who are scientific investigational science and technology personnel specializing in violent crime scenes. They help to determine the type of weapon used, whether there are combat, the direction of movement of the main invader, the victim or suspect, and whether the wound is caused by themselves. And dirt
