Tennessee Bureau of Investigation - As introduced, requires the bureau to maintain with each investigative case file copies of all original investigative materials, including audio and video files, recordings, transcripts, documents, reports, paperwork, and other print or digital media generated by the bureau and germane to the investigation by the bureau. - Amends TCA Title 4; Title 8; Title 10, Chapter 7, Part 5 and Title 38, Chapter 6.

SB 1351 requires the Tennessee Bureau of Investigation (TBI) to keep copies of all original investigative materials - such as audio/video recordings, transcripts, documents, and digital files - with each case file. This applies to all materials generated by the TBI that are relevant to an investigation. The bill amends Tennessee law to mandate this documentation practice across TBI cases. It directly affects TBI investigators and case management systems by establishing a new record-keeping standard. The law would take effect upon becoming law, ensuring all TBI investigations maintain complete digital and physical documentation.
