What type of personnel is specifically trained to collect physical evidence at a crime scene?

Crime scene investigation officers are specifically trained to collect physical evidence at a crime scene. Their primary responsibility is to ensure that evidence is gathered, documented, and preserved properly to maintain its integrity for analysis and potential court proceedings. They understand the protocols and techniques required to avoid contamination or loss of evidence and are skilled in using various tools and methods to secure the crime scene effectively.

The role of a forensic nurse, while important in the broader context of forensic investigations, focuses on providing medical care and gathering evidence related to injuries, rather than the comprehensive collection of physical evidence at a crime scene. Similarly, identification officers may have responsibilities related to documenting and identifying evidence, but their training and focus differ from the specialized practices employed by crime scene investigation officers. Lastly, forensic dentists concentrate on analyzing dental records and bite patterns, and are not involved in the direct collection of physical evidence at the scene.
