SALT LAKE CITY (AP) — Prosecutors say a California businessman teamed with a pair of Utah polygamists and helped them expand a biodiesel fraud scheme that ended up getting nearly $500 million in government funds. They say the money was used to buy luxury sports cars and million-dollar homes. U.S. Justice Department attorney Arthur Ewenczyk said Wednesday that gas station owner Lev Dermen sold polygamist Jacob Kingston on the false idea that he had an umbrella of government officials who would protect the scheme from prosecution. Dermen has pleaded not guilty to 10 counts including money laundering.. His attorney is set to give his closing argument later Wednesday.
