What should be done before touching or moving any item at a crime scene?

1. Review the police guidelines

2. Document it thoroughly

3. Wait for forensic experts

4. Confiscate it immediately

The correct answer is: Document it thoroughly

Before touching or moving any item at a crime scene, it is essential to document it thoroughly. This process includes taking photographs, making sketches, and noting the position of the item within the crime scene. Documentation ensures that there is a permanent record of the scene as it was originally found, which is crucial for any future investigations, legal proceedings, or forensic analysis. Thorough documentation provides a clear context for the evidence, preserving its integrity and maintaining the chain of custody. Failing to document an item before moving or disturbing it could lead to issues related to evidence contamination, loss of potential evidence, or challenges in court regarding the handling of the evidence. Therefore, meticulous documentation serves as a foundational step in crime scene management and evidence preservation.
