Crime Scene Investigation

CSI technicians use measurements in order to record the location of objects accurately and take note special conditions transitory to the crime such as a specific smell. They also document the scene and focus on evidence collection. Moreover, they take photographs of the scene and the evidences as well.
Examination of the body is conducted by the Crime Scene Investigation unit for crimes such as murder. Although the unit is not involved in the autopsy, they analyze the condition and position of the body and collect evidence. They document whether the victim is fully clothed or not, and if there is any sign of decomposition and to what extent. They also note injuries, activity, blood stains, positioning and other important details.
After the documentation of the crime scene, the Crime Scene Investigation technicians collect evidence. Using specific search patterns, they cannot miss any evidence. The main goal of evidence collection is preservation of the evidence. Evidence includes shoe and tire impressions, hair, dirt, bodily fluids, fibres, fingerprints or any item that may identify the suspect. Then they analyze the evidence using scientific techniques such as toxicology testing, microscopic examination, fingerprint comparisons and DNA testing.
