The State Bureau of Investigation’s mission is to serve Sheriffs, Police Chiefs, and District Attorneys as well as State and Federal partners, by investigating crimes and providing technical assistance in order to increase public safety for the citizens of the state of North Carolina. The SBI does so by conducting criminal investigations of allegations in areas of jurisdiction including narcotics, arson, election laws, misuse of state property, environmental crimes, human trafficking, child sexual abuse in day care centers, and threats made against public officials. The SBI provides support to local agencies related to computer crime investigations, use of force investigations, deaths in custody, crime scenes, financial crimes, missing and endangered persons, public corruption, cold cases, K9, special response team, bomb squad, and air wing. The SBI serves as North Carolina’s repository of information on criminal history records, fingerprint identification, expungements, sex offender registry, and concealed handgun permits. The SBI manages the North Carolina Information Sharing and Analysis Center (ISAAC), which is the fusion center for the state of North Carolina, as well as the Behavioral Threat Assessment Unit, which assesses and manages threats of mass violence.
