A Kansas City, Mo., man was sentenced in federal court today for having thousands of images of child pornography on his computer.

Duane E. Elliott, 57, of Kansas City, was sentenced by U.S. District Judge Dean Whipple to seven years in federal prison without parole. Elliott has also paid $3,000 in restitution to one of the victims whose images of child sexual abuse were included in his collection of child pornography.

On Oct. 28, 2014, Elliott pleaded guilty to two counts of receiving child pornography over the Internet.

A detective with the Independence, Mo., Police Department identified Elliott’s computer as sharing child pornography over the Internet. Elliott used a peer-to-peer file-sharing program to make approximately 20 movies of child pornography available for distribution over the Internet on multiple occasions.

Law enforcement officers executed a search warrant at Elliott’s residence and seized multiple computers and electronic storage media, which contained thousands of images of child pornography. Investigators found more than 1,000 movies and more than 2,500 images of child pornography. Some of the movies depicted sexually explicit conduct with children under the age of 12, and some depicted children in bondage or subjected to other sadistic or violent sexual abuse. Among the videos were two instructional videos, one titled, “How to Molest Juveniles.”

According to court documents, Elliott had more child pornography stored on an encrypted hard drive that could not be examined.
