To the extent possible, the attorneys and investigators shall be experienced in criminal law.(e) The supervisor of the bureau and bureau representatives designated by the supervisor have a right of access to all places of employment necessary to the investigation, may collect any evidence or samples they deem necessary to an investigation, and have all of the powers enumerated in Section 6314.(f) The supervisor of the bureau and bureau representatives designated by the supervisor may serve all processes and notices throughout the state.(g) In any case where the bureau is required to conduct an investigation, and in which there is a serious injury or death, the results of the investigation shall be referred in a timely manner by the bureau to the appropriate prosecuting authority having jurisdiction for appropriate action, unless the bureau determines that there is legally insufficient evidence of a violation of the law. If the bureau determines that there is legally insufficient evidence of a violation of the law, the bureau shall notify the appropriate prosecuting authority, if the prosecuting authority requests notice.(h) The bureau may communicate with the appropriate prosecuting authority at any time the bureau deems appropriate.(i) Upon the request of a county district attorney, the department may develop a protocol for the referral of cases that may involve criminal conduct to the appropriate prosecuting authority in lieu of or in cooperation with an investigation by the bureau.
