Forensic science is an important part of the criminal justice system, in both state and federal courts. Forensic scientists examine and analyze evidence from crime scenes and other relevant locations to develop objective findings that may assist in the investigation and prosecution of criminals, or clear an innocent person from suspicion.

Common forensic science laboratory disciplines include (1) forensic molecular biology (DNA); (2) forensic chemistry; (3) trace evidence examination (hairs, fibers, paints, polymers, glass, soil, etc.); (4) latent fingerprint examination; (5) firearms and toolmarks examination; (6) handwriting analysis; (7) fire and explosives examinations; (8) forensic toxicology; and (9) digital evidence.

Practitioners of these forensic science disciplines are usually found in medical examiner or coroner’s offices, universities, and private practices. And the United States Department of Justice maintains forensic laboratories at (1) the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF); (2) the Drug Enforcement Administration (DEA); and the Federal Bureau of Investigation (FBI).

In Missouri, forensic science plays a crucial role in the criminal justice system, aiding both state and federal courts. Forensic scientists in MO are tasked with examining and analyzing evidence from crime scenes to provide objective findings that can support criminal investigations and court proceedings. The state adheres to standards and regulations that ensure the reliability and admissibility of forensic evidence in court. Missouri has its own state crime laboratories, and local law enforcement agencies may also have their own forensic units. Additionally, forensic practitioners can be found in medical examiner or coroner’s offices, academic institutions, and private sector labs. The disciplines of forensic science, such as DNA analysis, forensic chemistry, and digital evidence, among others, are integral to solving crimes and achieving justice. At the federal level, agencies like the ATF, DEA, and FBI maintain specialized forensic laboratories that can support cases within Missouri and across the nation. The use of forensic science in Missouri is subject to both state statutes and federal laws that govern the collection, analysis, and presentation of forensic evidence.
