What is a key value of physical evidence in criminal investigations?

Physical evidence plays a crucial role in criminal investigations, primarily because it establishes identity and corroborates testimony. This type of evidence includes tangible items such as fingerprints, DNA, weapons, or any object found at a crime scene that can link a suspect to the crime or support the statements made by witnesses and victims.

By providing objective, scientific data, physical evidence can validate or challenge the narratives presented in court, reinforcing the reliability of witness testimony. Therefore, when investigators collect and analyze physical evidence thoroughly, it enhances the credibility of the case, as it offers a more comprehensive picture of the events that occurred. In essence, physical evidence acts as a solid foundation for building a case, providing a clear connection between the crime, the suspect, and the victim.
