The trial for 42-year-old Heath Umphenhour, which had been scheduled to begin this week in Doniphan County District Court, has been continued to May.  The trial is now scheduled to begin May 9th.    

Umphenhour  is charged with multiple counts of aggravated indecent liberties with a child, sexual exploitation of a child, aggravated criminal sodomy and attempted breach of privacy of a child or children.  He pleaded “ not guilty” to the charges last February.
