What Is a Crime Scene?

The location where an illegal act transpired or left evidence is called a crime scene. The premises are secured by the police in order for crime scene investigators to collect important physical evidence. If the location is not secured, the evidence may be tampered with and contaminated, making it difficult to ascertain the events that transpired within the premises. Securing the location involves taping off the premises from everyone except the crime scene investigators and the forensic scientists.

A crime scene can be classified according to where most of the illegal act was committed as primary, secondary, tertiary, and so forth. Thus, many crime scenes can come from a single crime. However, it is important to maintain the same kind of security in all crime scenes so as to find relevant trace evidence. Every crime scene undergoes an intense inspection and details are recorded before any kind of evidence is moved or brought back to the laboratory for analysis.

The goal of processing a crime scene is to discover the events that occurred, namely the crime, within the premises. Processing a crime scene involves photographing the crime scene before moving any evidence. Once photographing is done, physical evidence is then collected, whether it is fibers, hairs, bottle caps, or anything found to be relevant to the criminal case. Such evidence is then analyzed in terms of its components, and the part it played during the crime took place. This kind of processing allows investigators to reconstruct the events that happened.
