A Marlton man pleaded guilty Wednesday to advertising more than 20,000 images of child pornography for distribution online through peer-to-peer file sharing software, according to U.S. Attorney Paul Fishman.

Evan C. Corbett, 34, admitted that he shared the images between July 2008 and May 2009 over the Internet with the file sharing programs, authorities said. He also admitted downloading child porn on his computers in Marlton and allowing others to download the images, identified by explicit names, authorities said.

Corbett, who was arrested in August, faces up to 20 years in prison with a mandatory minimum of five years. Sentencing is scheduled for Sept. 1. - Darran Simon
