What is physical evidence?

Physical evidence refers to tangible items that can be perceived through the senses, particularly those that can be handled, measured, or observed. This type of evidence plays a crucial role in investigations, as it can directly link a suspect to a crime, confirm or deny a hypothesis, or provide factual information regarding a case.

For instance, trace materials like fingerprints, hair, and fibers found at a crime scene can serve as physical evidence that connects a person to that location or activity. Similarly, items such as weapons or clothing can help establish or refute claims made during an investigation. Unlike subjective opinions, legal documents, or eyewitness accounts, physical evidence stands out due to its ability to present tangible proof that is not reliant on personal perspectives or recollections. Therefore, recognizing physical evidence as something concrete and scientifically verifiable is essential for effective fire investigation and analysis.
