Law Enforcement Investigations

Law enforcement investigations close cases and can prevent new crimes from occurring. Training in proper investigative procedures, such as those for handling evidence, and access to tools and resources can help law enforcement officers carry out successful investigations.
NIJ research enhances the forensic aspects of investigations into specific types of crimes and cases. NIJ supports the creation and maintenance of investigative resources, such as manuals, databases and training courses. NIJ has funded research in several areas relevant to investigations, including crime mapping, forensic tool testing and evidence reliability. NIJ also directly funds cold-case investigations.
