Crime scene investigation definition

7 steps of a crime scene investigation

A crime-scene investigation aims to recognize, document and collect evidence at a crime scene. This evidence may include but is not limited to guns, clothes, personal items, footprints, tyre tracks, and fingerprints. Investigators will also talk to witnesses and gather every information that seems pertinent to the case. Once all the evidence is gathered, it is carefully examined and analysed in the forensic science laboratory and used to build a case against the suspect.

Importance of crime scene investigation

Solving the crime will then depend on putting together the evidence to form a picture of what happened at the crime scene. Crime scene investigation is important in identifying suspects and arresting the offender. By following the right investigation procedures, law enforcement officials can build a strong case against the offender and assist in a speedy trial.

The process can be complicated and time-consuming, but it is necessary to ensure that the offender is held accountable for their actions. A small amount of blood, hair, fibre, or a part of the skin or different materials can help a crime to be reconstructed and lead investigators to the responsible person. Similarly, fingerprints left on objects at the crime scene can be compared to a database of known prints to identify a suspect.

Note: Human hairs can be used to analyse nuclear DNA. The root ends of the hairs are looked at with a microscope to see if they are suitable for DNA Analysis. The following are the primary goals of the investigative process in a criminal or civil case. Crime scene investigators work to establish the fact that a crime has taken place and who committed the crime.

An investigator is a person who conducts investigations to collect information and evidence related to crime. Investigators can work at various places, including law enforcement agencies, private investigation firms, and corporate security departments.
