The Tennessee Bureau of Investigation (TBI) is an independent, statewide law enforcement agency in Tennessee. Its mission is to provide professional, effective, and efficient investigative, forensic, and criminal justice information services to local, state, and federal law enforcement agencies, as well as the public. TBI investigates a wide range of criminal activities, including homicides, drug trafficking, public corruption, cybercrime, and crimes against children, and operates state-of-the-art forensic laboratories.
Serves as the central administrative and operational command center for TBI, housing executive leadership, specialized investigative units, administrative support services, and a primary forensic science laboratory.
The TBI headquarters complex includes advanced forensic science laboratories, a training center, and secure facilities for handling sensitive investigations and evidence.
The work culture at TBI headquarters is characterized by professionalism, a strong sense of duty, collaboration among diverse units, and a commitment to justice and public safety. It is a demanding environment focused on accuracy and thoroughness in investigations and forensic analysis.
The Nashville headquarters is significant as it centralizes TBI's statewide operations, facilitates coordination with other state and federal agencies, and houses critical resources necessary for complex criminal investigations and forensic services for the entire state.
As a state-level law enforcement agency, the Tennessee Bureau of Investigation's primary jurisdiction and operations are within the state of Tennessee. TBI does not maintain a global presence with international offices. However, it collaborates with federal agencies (e.g., FBI, DEA) and, on occasion, international law enforcement organizations on cases that may have interstate or international connections, such as human trafficking, cybercrime, or fugitive apprehension. This cooperation is conducted through established protocols and partnerships rather than a direct global operational footprint.
