What is an example of forensic science in criminal investigations?

Forensic science plays a crucial role in criminal investigations by applying scientific principles and techniques to analyze evidence. DNA analysis is a prime example of forensic science because it involves examining biological material collected from a crime scene, such as blood, hair, or bodily fluids, to establish or refute the presence of a suspect at the scene. The uniqueness of an individual's DNA makes this type of analysis incredibly reliable in identifying individuals involved in criminal activities or exonerating those wrongfully accused.

In contrast, negotiation refers to the process of discussion between parties to reach an agreement, which isn’t a scientific method, and witness testimony relies on personal accounts, which can be subjective. Interrogation logs document interactions between law enforcement and suspects but do not involve scientific analysis or techniques. Thus, DNA analysis stands out as a fundamental aspect of forensic science in the context of criminal investigations.
