A former Cheyenne firefighter accused of possessing and distributing child pornography is now being prosecuted in federal court.

Thirty-one-year-old Joseph Golden had been charged in state district court, where he pleaded not guilty last week. The Wyoming Tribune Eagle  reported Monday that the charges against him have been re-filed in U.S. District Court.

According to court documents, a Wyoming Division of Criminal Investigation special agent received information in August regarding a Yahoo! user who had allegedly sent a nude photo of an elementary-aged girl to another person. The sender's screen name was allegedly traced to Golden.

On Oct. 5, several DCI agents served a search warrant on Golden's home. They say they found several images and a video showing children in sexually explicit conduct.
