KANSAS CITY, Mo. - Samuel Smith used a credit card to buy child porn over the Internet.
The paper trail left by his transactions led to a guilty plea Monday in federal court.
Smith, 22, of Platte City, admitted received child pornography over the Internet, according to a news release from the U.S. Attorney's Office in Kansas City.
He used his credit card to subscribe to Pedo Heaven and Dreamzone from which he downloaded the porn.

Law officers found hundreds of images of child pornography on Smith's computer, including movies featuring child porn, according to the news release.
