Which role is typically responsible for collecting physical evidence at a crime scene?

The role typically responsible for collecting physical evidence at a crime scene is the crime scene technician. This position is specialized in processing crime scenes and is trained in various techniques for collecting, preserving, and documenting evidence. A crime scene technician has the expertise to meticulously gather evidence without compromising it, ensuring that the chain of custody is maintained for future legal proceedings. They often use specialized tools and methods to properly collect a wide range of evidence, from fingerprints and biological samples to physical objects that might be relevant to an investigation.

While detectives and investigators may play crucial roles in analyzing evidence and developing leads, they primarily focus on case investigation rather than the hands-on collection of physical evidence at the scene. Patrol officers may secure the perimeter and ensure safety at the scene, but they are not typically the ones responsible for the detailed collection and processing of evidence.
