What steps should you take to preserve a crime scene until investigators arrive?

• A. Do not touch or move items, document layout, take notes, secure area, and limit access.
• B. Move items to preserve evidence.
• C. Begin a search for suspects.
• D. Tamper with evidence to speed things.

Answer: (A)

The main concept here is preserving evidence by preventing contamination and keeping the scene intact until investigators arrive. Not touching or moving items is essential because even small actions can destroy or alter evidence like fingerprints, DNA, fibers, or trace material, making it impossible to determine what happened or who was involved. Documenting the scene layout, taking notes, and creating a record of positions and conditions helps investigators later recreate the sequence of events and understand how evidence relates to one another. These steps establish a reliable baseline of what the scene looked like when responders first encountered it. Securing the area and limiting access minimizes the risk of additional disturbance, contamination, or accidental loss of evidence by bystanders, witnesses, or responders. If anyone must enter for safety or to render aid, they should do so with minimal disturbance and communicate their actions so investigators can account for changes. Movements of items, searching for suspects at the scene, or tampering with evidence would compromise the integrity of the investigation and should be avoided.
