What is essential for physical evidence to be useful in an investigation?

For physical evidence to contribute meaningfully to an investigation, it is crucial that it is collected, protected, and submitted properly. The integrity of physical evidence is paramount; improper handling can lead to contamination, loss, or misinterpretation of the evidence.

When evidence is collected, it must be secured in a manner that maintains its original condition. Skills in evidence collection include using appropriate tools, packaging materials, and following protocols to prevent alteration or degradation. Additionally, maintaining a clear chain of custody ensures that the evidence can be traced back through each person who handled it, which is vital for its admissibility in court.

The option about ignoring physical evidence directly contradicts effective investigative practices, as does the idea of disposing of evidence after analysis. Documentation in written form is certainly important, but it does not encompass the entire process of handling physical evidence, which requires both proper collection methods and protective measures. Hence, proper handling and submission are essential for physical evidence to have utility in an investigation.
