About Forensic Science Technicians

Forensic Scientists apply scientific methods to analyze physical evidence collected from crime scenes and provide expert testimony in legal proceedings. They work in crime laboratories operated by law enforcement agencies, medical examiners' offices, and private laboratories. Forensic scientists specialize in disciplines such as DNA analysis, trace evidence (fibers, hair, glass, paint), fingerprint examination, toxicology, firearms and toolmark examination, digital forensics, and questioned document examination. DNA analysts extract and analyze genetic material from biological evidence to identify individuals. Toxicologists analyze blood and tissue samples to detect drugs, poisons, and alcohol. Trace evidence scientists examine microscopic materials transferred between individuals or between a person and a scene to establish contact. Firearms examiners compare bullets and cartridge cases to determine whether they were fired from a specific weapon. All findings must be documented rigorously, subjected to peer review, and reported in written scientific reports that are admissible in court. Expert witness testimony requires translating complex scientific findings into clear explanations for judges and juries. ASCLD accreditation standards govern laboratory quality systems.
