What steps should be taken to preserve a crime scene?

Preserving a crime scene means preventing contamination or loss of evidence while creating an accurate record of what happened. Start by securing the scene: establish a perimeter, control entry, and keep unauthorized people out so nothing is disturbed. Next, protect victims and witnesses by ensuring safety and keeping them away from unnecessary movement or handling of items, which helps maintain integrity and avoids unintended changes to the scene or statements. Limit access to authorized personnel only, with a clear log of who enters and leaves, so the chain of custody isn’t broken. Document the scene thoroughly to capture its original condition: photograph from multiple angles before anything is moved, take detailed notes, measure key distances, and create a sketch showing the placement of evidence and relationships between objects. Finally, collect and package evidence properly using appropriate containers, seal and label each item, and maintain an unbroken chain of custody that records every transfer and handling. This combination preserves the integrity of evidence for investigation and court proceedings. Other approaches that move evidence or expose the scene to bystanders risk contamination, alter the scene, or disrupt the chain of custody, which can compromise admissibility and the investigation.
