Document Summary

Securing the crime scene to the greatest extent possible. Calling for any additional personnel needs such as other officers and/or forensic investigators. The boundaries of the crime scene must be secured with scene tape, ropes, or cones. The secured area should include the area where the crime took place and the surrounding area where physical evidence may be located. Once the boundaries are secured, guards may be posted to restrict access. A detailed log is kept of personnel movements in and out of the crime scene. This log includes personnel names and time of entry or exit. Investigators should never do anything that might alter the crime scene including smoking, eating, drinking, or littering. The search for physical evidence at a crime scene must be thorough and systematic. The search pattern selected will normally depend on the size and locale of the scene and the number of collectors participating in the search.
