A Clinton man has been sentenced to six months in federal prison for illegally possessing machine guns.The U.S. Attorney for the Southern District of Iowa says 41-year-old Carl LaVerne Foley was sentenced after pleading guilty to possessing four machine guns and an illegal short-barrel rifle.

Federal agents arrested Foley, a licensed federal firearms dealer, after complaints that he was firing machine guns at a Princeton shooting range. Agents used a search warrant to enter his Clinton home and found a World War Two era Browning .50 caliber heavy machine gun, along with two British World War Two era Sten submachine guns. They also found a .22 caliber rifle rigged to fire automatically via a joystick or button, and an illegal short barrel rifle.
