Crime Scene Investigation Process
Scene processing means the sequence of steps taken in order to investigate a crime sight. Even though the manner and techniques may vary between professionals involved, their objectives art similar: to rebuild the accurate circumstances of the crime by means of the identification of the series of proceedings and to collect substantial evidence that may lead to the discovery of the perpetrators.
Crime Scene Investigation normally begins at the site where the offense was committed. The area should be secluded and secured in order to avoid the destruction of vital physical proofs that may lead police authorities to associate the culprits into the victim. The size of the location to be secluded and secured differs with every case and series of procedures designed in order to protect and secure the evidences are followed.
The first police authority in the scene is accountable in avoiding unnecessary police personnel and civilians from going near the crime scene and frequently establishes a boundary around scene of the crime with tapes or sometimes ropes. If eyewitnesses are available, they are recognized and must stay outside the boundaries of the crime sight while waiting for query by the investigating team. If death has happened, a crime sight technician and investigators are asked to go to the Crime Scene in order to assist the police authority.
The crime sight technician is skilled in finding and determining physical proofs like hair, fibers, bloodstained objects, empty bullet shell and body fluids which can be seen in carpets, furniture, on walls and others. The sight and every piece of proof is photographed cautiously and then collected and conditioned properly to prevent contamination, to be analyzed later at the laboratory. The technician also writes a detailed report of the crime scene and also describes the evidences found.
The investigator interrogates witnesses, collects information from the police officer in the crime scene, the technician of the crime scene, pathologist, the coroner and other specialists that are seen in the scene like the forensic anthropologist. The investigator has the responsibility for managing the information to be given to the press. He will talk to the prosecutor the available evidences and some information in order to determine the lawful direction of the examination, since both have responsibility in the whole investigative procedure and for making a case if prosecuting persons charged with the offense.
