CHICAGO (WLS) -- A Chicago man has been sentenced to six years in federal prison for illegally selling guns and "switch" devices that can turn semi-automatic firearms into machine guns.
Federal investigators said Rogelio Castaneda sold nine guns and 28 "switch" devices to undercover agents.
A recent analysis by the ABC7 I-team found a significant jump in arrests in Chicago, linked to guns modified with switches.
