The Importance of Effective Crime Scene Management

The purpose of this paper is to provide a review of the relevant literature to explain the importance of securing crime scenes in order to protect evidence from contamination and preserve it for use by the courts. In addition, a discussion concerning different methods that might be necessary to document evidence at a crime scene and different collection methods that might be used at a crime scene is followed by an explanation concerning the chain of custody and why it is important. Finally, the repercussions of failing to protect evidence or establish chain of custody is followed by an explanation concerning how an investigator or forensic expert differentiates between what is or is not evidence. A summary of the research and key findings concerning the foregoing issues are presented in the paper’s conclusion.

Conclusion

At first blush, securing a crime scene sounds like a straightforward enterprise. The research, however, was consistent in showing that there are a number of factors that must be taken into account when securing a crime scene, including most especially the safety and wellbeing of first responders and crime victims.
