HB 2606 creates a statewide cold case division within Tennessee's Bureau of Investigation (TBI), organized into three geographic regions. Each region must have a director and at least five detectives to handle unsolved missing persons and homicide cases. Local law enforcement agencies must submit such cases to the TBI cold case division after 10 years without resolution. Families of victims may also request case file access under specific conditions, including if the case is unresolved for 10+ years or the local agency lacks a dedicated unit.
