A federal jury on Tuesday found a Kansas City man guilty of illegally possessing two firearms, including a street-sweeper shotgun.

Ronald F. White Jr., 32, faces up to 20 years in prison on the charges. A sentencing date has not been set.

In addition to the drum-fed, semi-automatic, 12-gauge shotgun that was not registered to him, White also possessed a stolen semi-automatic handgun that fires the same ammunition as an AK-47 rifle.

Kansas City police found the firearms in October 2013 when they served a search warrant at the home of White’s relatives, according to federal prosecutors.

In 2007, White was acquitted of murder charges by a Jackson County jury. That case stemmed from the 2003 killing of two men outside a Kansas City liquor store.
