What type of forensic expert might analyze the contents of a pill bottle found at a crime scene?

A forensic toxicologist would be the appropriate expert to analyze the contents of a pill bottle found at a crime scene. This field of forensic science focuses on the effects of drugs and other substances on the body, as well as detecting and identifying these substances in biological samples. When it comes to a pill bottle, a forensic toxicologist would examine and identify the specific substances contained within the pills, determine their potential effects on human health, and assess if they could be implicated in a crime, such as overdose, poisoning, or other forms of drug-related offenses.

Other experts mentioned have distinct roles: a forensic chemist typically analyzes chemical compounds and materials, but may not specialize specifically in the biological effects as related to human ingestion; a forensic pathologist focuses on determining the cause of death, often through autopsies, but does not usually analyze substances directly from evidence; and a forensic anthropologist studies human skeletal remains to determine identity or cause of death, which would not involve examining the contents of pill bottles. Thus, the role of the forensic toxicologist is uniquely suited to the investigation of potentially harmful substances within medication found at a crime scene.
