What must forensic analysis of substances include?

Forensic analysis of substances fundamentally relies on understanding their chemical composition because this process allows investigators to identify, categorize, and compare materials involved in a criminal investigation. Chemical composition analysis is crucial because it helps determine the nature and origin of substances, such as drugs, poisons, or bodily fluids, which can provide vital evidence in a case.

Identifying the specific chemical makeup can lead to insights into the circumstances surrounding a crime, including motives, methods, and the identity of suspects or victims. This objective analysis is essential for ensuring that the evidence presented in court is reliable and scientifically sound, which can significantly impact the outcomes of legal proceedings.

In contrast, while eyewitness accounts can provide context, they are inherently subjective and do not provide the forensic certainty that chemical analysis delivers. Digital footprint examination serves a different purpose, often pertaining to online behavior rather than physical substances. Crime scene cleanup is a necessary process following an investigation but is not part of the forensic analysis of evidence itself. Thus, understanding the chemical composition of substances stands as a cornerstone of forensic science.
