DCJS Crime Scene Management & Evidence Handling Questions and Answers Flashcards

The correct sequence for processing physical evidence at a crime scene is:

Answer: Photograph and document first, then collect

Evidence must be photographed and documented in place before collection to preserve the original scene context.

Biological evidence such as blood or saliva should be stored in:

Answer: Paper bags or envelopes to allow moisture to escape

Moisture trapped in plastic bags causes biological evidence to degrade; paper packaging allows airflow and prevents mold.

Trace evidence is best described as:

Answer: Tiny materials like fibers, hair, or glass fragments transferred during contact

Trace evidence consists of microscopic or small materials that transfer between persons, objects, or environments during contact.

Before collecting a fingerprint from a surface, an officer should FIRST:

Answer: Photograph the fingerprint in its original undisturbed position

Photographing the print in place documents its location and condition before any development or collection technique is applied.

Digital evidence such as mobile phones and computers should be:

Answer: Seized, packaged appropriately, and submitted per agency digital evidence policy

Digital devices must be handled by trained personnel following strict protocols to prevent data alteration, encryption triggers, or remote wipes.

When an officer is uncertain whether an item found at a crime scene is evidence, the officer should:

Answer: Treat it as potential evidence and document it thoroughly

When in doubt, officers should err on the side of preservation; it is far easier to exclude an item later than to recover a discarded one.
