On Monday, Supreme Court clerk Scott Harris issued a brief statement on the Henthorn case saying, “The petition for writ of certiorari is denied. Justice Gorsuch took no part in the consideration or decision of this petition.”

The statement means the highest court in the land declined to review a decision from last summer by the 10th U.S. Circuit Court of Appeals which upheld Henthorn’s murder conviction.
