Wyo. Stat. § 7-5-308

(a) In addition to its powers of indictment, a statewide grand jury impaneled under W.S. 7-5-301 through 7-5-309 may, at the request of the attorney general, cause an investigation to be made into the extent of organized criminal activity within the state and return a report to the attorney general.

(b) Disclosure of matters occurring before the grand jury, other than its deliberations and the vote of any juror, may be made to the attorney general and to any district attorney for use in the performance of their duties. Those officials may disclose so much of the grand jury's proceedings to law enforcement agencies as they deem essential to the public interest and effective law enforcement.

(c) Except as provided in subsection (b) of this section, a juror, attorney, interpreter, stenographer, operator of a recording device or any typist who transcribes recorded testimony may disclose matters occurring before the grand jury only when so directed by the court preliminarily to or in connection with a judicial proceeding or when permitted by the court at the request of the defendant upon a showing that a particularized need exists for a motion to dismiss the indictment because of matters occurring before the grand jury.

(d) No obligation of secrecy may be imposed upon any person except in accordance with this section. The court may direct that an indictment shall be kept secret until the defendant is in custody or has given bail, and in that event, the clerk shall seal the indictment and no person shall disclose the finding of the indictment except when necessary for the issuance and execution of a warrant or summons.
