Which are the three main types of evidence collected in crime scene investigations?

The correct answer identifies the three primary categories of evidence typically collected during crime scene investigations. Testimonial evidence refers to information and statements provided by witnesses or individuals who have firsthand knowledge of the incident. Documentary evidence encompasses any written or recorded material that can support a case, such as photographs, videos, or official documents. Physical evidence represents tangible items collected from the crime scene, which can include fingerprints, weapons, or biological samples relevant to the investigation.

Each type of evidence plays a vital role in understanding and reconstructing the events surrounding a crime. Integrating testimonial and documentary evidence with physical evidence helps create a more comprehensive picture of what transpired, thereby strengthening the investigation and any subsequent legal proceedings. Understanding these categories aids investigators in methodically collecting and analyzing evidence to ensure a rigorous examination of a crime scene.
