When is it appropriate to secure the crime scene for follow-up investigation?

Securing the crime scene is a critical step in ensuring that evidence is preserved and that further investigation can occur without contamination or loss of vital information. It is appropriate to secure the crime scene if necessary until further investigation can be conducted, regardless of the presence of visible injuries or suspects.

The rationale behind this is that crime scenes can contain various forms of evidence that may not be immediately apparent. By securing the scene, investigators can maintain control over the area, preventing unauthorized personnel from entering and potentially altering or destroying evidence. This approach allows for a thorough investigation that respects the integrity of the scene, allowing for all aspects to be examined properly during follow-up investigations.

In contrast, securing the scene only under specific conditions—such as visible injuries or confirmed suspects—potentially limits the effectiveness of the investigation. Every crime scene should be treated with care until all necessary investigative procedures are complete. This ensures that all evidence is considered and that investigators can approach the situation comprehensively.
