What should be avoided during the investigation to preserve evidence?

In an investigation, preserving evidence is critical for establishing the facts surrounding an incident. Moving items without documentation can significantly compromise the integrity of the evidence. When items are moved or disturbed, their original state is altered, making it difficult to determine how they were positioned in relation to the scene and what role they may have played in the incident.

Documentation is essential because it provides a clear record of the evidentiary context, including the condition, location, and relationship of each item to the overall scene. When items are moved without proper documentation, the chain of custody may be broken, potentially rendering the evidence inadmissible in legal proceedings.

Thorough notes, proper protective gear, and communication with colleagues are all important components of a successful investigation that do not negatively impact the integrity of evidence. In contrast, moving evidence without documenting it undermines the entire investigative process.
