A Baton Rouge man was sentenced Wednesday to eight years in federal prison after pleading guilty to one count of distribution of child pornography.

Brad J. Case, 30, also must serve 20 years under post-prison supervision by federal investigators, Chief U.S. District Judge Brian A. Jackson ruled.

“On May 8, 2011, Case distributed 25 images of child pornography to an undercover special agent with the FBI,” U.S. Attorney Donald J. Cazayoux Jr. said in a written statement. Cazayoux said Case sent those images to the undercover agent over the Internet.

“The FBI was able to trace the source of the child pornography to an apartment located in Baton Rouge and rented by Case,” Cazayoux added.

The charge to which Case pleaded guilty said images he unknowingly sent the FBI were “visual depictions (that) involved the use of minors engaging in sexually explicit conduct.”

In return for Case’s guilty plea on the distribution charge, prosecutors dropped a second charge that alleged Case possessed additional child pornography when FBI agents searched his apartment.

The plea agreement was signed by Case, his attorney, Joseph K. Scott III, and Assistant U.S. Attorney J. Christopher Dippel Jr.
