Outline the basic steps for securing a crime or incident scene.

• A. Initial actions include securing perimeters and interviewing witnesses.
• B. Secure the scene by securing perimeters, limiting access, and photographing the area.
• C. Establish a safe perimeter, prevent contamination, record entry/exit, collect and preserve evidence, and document chain of custody.
• D. Move evidence to a secure location immediately.

Answer: (C)

Securing a crime or incident scene hinges on maintaining its integrity from the moment you arrive. Begin by establishing a safe perimeter to define the area and prevent unauthorized entry, then strictly limit access so only authorized personnel move in and out, with every entry and exit recorded. This careful control helps prevent contamination and preserves the scene in its original state. Documentation of movements is essential because it creates a clear record of who handled evidence and when, which supports the chain of custody.

Photographs or videos are important to capture conditions as found, but they must accompany a process that preserves evidence, rather than replace it. The focus is on preventing contamination, collecting and preserving items properly, and maintaining a thorough log of all handling. Evidence should be collected and packaged correctly, labeled, and stored securely to prevent degradation or cross-contamination, with every transfer of custody documented so the trail can be followed later.

Interviews with witnesses are valuable, but they should occur after the scene is secured to avoid introducing contamination. Moving evidence off-site immediately is not appropriate without proper packaging and authorization, as it can compromise the integrity of the evidence.

That combination of perimeter control, access limitation, meticulous documentation, proper collection and packaging, and a clear chain of custody is why this approach best outlines the basic steps for securing a crime or incident scene.
