Crime Scene Investigation Services

Law enforcement units and/or crime laboratory technicians that are responsible for recording information about a crime scene, and collecting and preserving evidence for forensic analysis. Investigation teams (which may include ballistics experts, fingerprint examiners, blood and DNA evidence technicians, footprint technicians and other specialists) conduct a systematic search of the crime scene; observe and document the scene via photographs, sketches, written notes and reports; identify and collect physical evidence such as fingerprints, footwear impressions, fabric impressions, tire marks, firearms evidence, hair, fibers, biological fluids and other materials for analysis; examine other types of evidence such as bloodstain patterns and gunshot residue that may help to reconstruct the likely sequence of events at the crime scene; mark and tag the evidence; and initiate the "Chain of Custody" documentation.
