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.

HB 1394 requires the Tennessee Bureau of Investigation (TBI) to maintain copies of all original investigative materials - such as audio/video recordings, transcripts, documents, and digital media - with each case file. This applies to all materials generated by the TBI that are relevant to an investigation. The bill mandates this record-keeping for every TBI investigation, amending specific Tennessee Code sections to formalize the requirement. The policy change directly affects the TBI's internal procedures for handling case documentation.
