The forensic biology/DNA section identifies bodily fluids, including semen and blood, and analyzes them for DNA. Analysts test evidence from a variety of crimes, but most of the work is related to sexual assaults.
When a DNA profile is detected it can be compared to reference samples from individuals associated with a case. The goal is to match between an unknown profile found at a crime scene to a known profile. By doing this, analysts can either identify or eliminate crime suspects. Profiles can also be entered into the national DNA database, or the Combined DNA Index System (CODIS,) to look for a match. CODIS includes profiles from local, state and federal databases.
