A former Denver, Iowa woman has pleaded guilty to buying guns for illegal aliens. 36-year-old Christine McFadden was charged earlier this month with purchasing firearms in her name, which were then distributed to illegal aliens in the Waterloo area between November of 1999 and November of 2001. McFadden admitted in federal court that she bought several firearms and gave them to her roommate, who she knew was in the U-S illegally. The roommate then distributed some of the weapons to other illegal aliens.
