Steven Roland, 44, pleaded guilty Friday to receiving thousands of images of child pornography over a four-month span.
Roland knowingly received more than 28,000 images and 50 videos containing child pornography while living in Citrus Heights between Dec. 28, 2013, and March 19, 2014, according a U.S Department of Justice news release. He was living in Arizona when arrested.
The Sacramento Internet Crimes Against Children Task Force identified Roland via an undercover investigation examining use of peer-to-peer file sharing networks.
Roland is scheduled to be sentenced Jan. 19. He faces a minimum penalty of five years in prison and a maximum penalty of 20 years and a $250,000 fine, according to court documents.
