CRIME SCENE INVESTIGATION LABORATORY

Abstract:


Our Crime Scene Investigation Laboratory needs to cover a wide range of investigation work because a crime scene investigator have no limits for his duties. His works, duties and responsibilities depend on type of scene of crime and vary accordingly. Basically a crime scene is place where a criminal offence has occurred. As the crime is diverse in nature the crime scene differs with each crime. The only consistent about a crime scene is its inconsistency in location, nature of the crime, the person involved in a crime etc. Crime scene can be classified as, primary crime scene where the main crime has occurred and secondary where subsequent articles are found.

Forensic Science begins at the crime scene. If the investigator cannot recognize physical evidences or cannot properly preserve it for laboratory examination, no amount of sophisticated laboratory instrumentation or technical expertise can salvage the situation. Criminals always use a latest technology to commit a crime. Hence most of the crimes are very complex to solve and the crime scene difficult to access and retrieve the physical evidence. The main components of crime scene management are Information management, Man power management, Technology management, Logistics management, and Available resource management. The procedures followed by a crime scene investigator should be fool proof and with legal standing and scientific security.
