Utah Code § 26B-8-221: Authority of county attorney or district attorney to subpoena witnesses and compel testimony -- Determination if decedent died by unlawful means.

(1) The district attorney or county attorney having criminal jurisdiction may subpoena witnesses and compel testimony concerning the death of any person and have such testimony reduced to writing under his direction and may employ a court reporter for that purpose at the same compensation as is allowed to reporters in the district courts. When the testimony has been taken down by the court reporter, a transcript thereof, duly certified, shall constitute the deposition of the witness.

(2) Upon review of all facts and testimony taken concerning the death of a person, the district attorney or county attorney having criminal jurisdiction shall determine if the decedent died by unlawful means and shall also determine if criminal prosecution shall be instituted.
