Florida Fire State Practice Exam

In forensic investigation, which of the following is considered a physical evidence?

1. Witness statements

2. Explosion debris

3. Police reports

4. Suspect confessions

The correct answer is: Explosion debris

Physical evidence refers to tangible items that can be collected and analyzed during a forensic investigation, helping to establish facts about a crime scene or event. Explosion debris is a prime example of physical evidence, as it can provide vital information about the nature of the explosion, such as the materials used, the location of the blast, and potential sources of ignition. This evidence can be collected, preserved, and examined in a laboratory setting, allowing forensic experts to determine aspects of the incident that may not be clear through eyewitness testimony or circumstantial evidence. In contrast, witness statements, police reports, and suspect confessions are categorized as testimonial evidence. While these types of evidence can be valuable in a forensic investigation, they are not physical items that can be directly analyzed. Testimonial evidence relies on individuals' accounts and perceptions, making it more subjective compared to the objective analysis that can be conducted on physical evidence like explosion debris.
