Which statement correctly describes the relationship between the first on-scene officer and evidence handling?

• A. The first Security Officer begins the chain of custody
• B. The police begin the chain of custody
• C. The lab technician begins the chain of custody
• D. The prosecutor begins the chain of custody

Answer: (A)

The first on-scene security officer begins the chain of custody because this is where the documented control of evidence starts. When the officer arrives, they secure the scene, identify the item as potential evidence, accurately describe it, label and seal it, and record who collected it and when. This initial documentation creates the auditable trail that will be carried forward every time the item changes hands. If the chain doesn’t start with the first person who handles the evidence, gaps can appear in the record, casting doubt on its integrity. Later roles—such as lab technicians or prosecutors—may handle or view the evidence, but they do not originate the chain at the scene.
