Step-by-step explanation:
The step of the crime scene protocol that involves evaluating and collecting physical evidence from a crime scene is the documentation and collection step. This is an important part of the investigation process because the evidence collected can provide crucial information about the crime and the individuals involved.
Crime scene investigators use various techniques and tools to carefully document and collect evidence, such as photographs, sketches, measurements, and packaging materials. They ensure that the evidence is properly preserved and labeled to maintain its integrity.
The collected evidence is then sent to a forensic laboratory for further analysis, where other forensic scientists, including chemists, biologists, and biochemists, conduct tests to extract vital information that can help solve the crime.
