Their work helps law enforcement agencies understand what happened during a crime and can provide crucial information for legal cases. These scientists often specialize in various fields, including toxicology, DNA analysis, and ballistics. They may work in laboratories or at crime scenes, using advanced technology and techniques to gather and interpret data. Their findings can be vital in court, helping to establish facts and support investigations.
