Describe the standard sequence of operations for processing a crime scene from arrival to release.

• A. Safety assessment; scene isolation; documentation; evidence search; collection/packaging; transport to lab; analysis; reconstruction; final reporting.
• B. Safety assessment; scene isolation; documentation; evidence search; transport to lab; collection/packaging; analysis; reconstruction; final reporting.
• C. Safety assessment; scene isolation; documentation; evidence search; collection/packaging; transport to lab; analysis; reconstruction; final reporting.
• D. Safety assessment; scene isolation; documentation; evidence search; collection/packaging; transportation to lab; analysis; reconstruction; final reporting.

Answer: (C)

The sequence tested is about preserving evidence and maintaining a clear chain of custody as you move from arrival to releasing the scene. After arriving, you perform a safety check and isolate the scene to prevent contamination. You document the initial conditions—photos, sketches, notes—so you have a reliable record of the scene before anything is disturbed. Then you conduct an evidence search to identify items that may be evidentiary. Only after you’ve identified potential evidence do you collect and package it properly, using appropriate containers, seals, and labeling to keep it tamper-evident and to prevent cross-contamination. Once packaged, the evidence is transported to the laboratory for analysis. After analysis, investigators work through reconstruction and then prepare final reporting. The reason this order is correct is that packaging before transportation protects the integrity of the evidence and establishes a solid chain of custody; moving something to transport before packaging risks loss, contamination, or tampering and undermines accountability.
