An eastern Nebraska man has been sentenced to 10 years in prison for collecting a massive cache of child pornography that included images of infants

U.S. Attorney Deborah Gilg announced that 52-year-old Robert Sheldon, of Arlington, was sentenced Tuesday in federal court for receiving child pornography.

Authorities say a search of Sheldon’s house in February turned up more than 200,000 sexually explicit images of young children on computer hard-drives. Authorities say Sheldon’s was the largest ever uncovered by the Nebraska Attorney General’s office’s Rural Cybercrime Unit.

The collection included more than 600 images involving the sexual abuse of children believed to be 1-year-old or younger and included images involving the rape and torture of prepubescent children.

Sheldon will be subjected to a lifetime term of supervision following his release.
