Which of the following is an example of "Physical Evidence"?

Physical evidence refers to tangible items or materials that can be collected and analyzed in a forensic investigation. DNA samples are classified as physical evidence because they can be directly gathered from a crime scene, providing concrete biological material that can link a suspect to an event or identify a potential victim. DNA evidence is often pivotal in criminal investigations and can be used in court to support claims or establish connections, making it a critical component of physical evidence.

In contrast, witness testimony and reported actions of the suspect are examples of testimonial evidence, which relies on human accounts rather than tangible materials. Weather conditions, while they can influence the context of the incident, do not constitute physical evidence themselves as they are not objects or biological samples that can be collected and analyzed. Understanding the distinction between physical and testimonial evidence is key in forensic science and investigative processes.
