A seventh man has pleaded guilty in connection to the child pornography ring at Fort Dix prison.

Charles Bush says he had an SD card with over 2,000 pictures and 95 videos.

Bush has been charged with possession of child porn.

Earlier this month, Christopher Roffler, 30, pleaded guilty, according to federal prosecutors.

He faces at least 10 years in prison when he's sentenced in August, a term he would serve after his current sentence for trafficking in child pornography is completed.

Prosecutors say Roffler was among the several prison inmates who used contraband cellphones and removable storage cards to share child porn.

Roffler admitted having a memory card that contained 305 videos and 16 images of child porn, some of which depicted prepubescent children and sadistic and masochistic conduct.

He also admitted using a smartphone to view and possess child porn.

William Noble, 52, and Jacob Good, 31, are also accused in the case. All are currently incarcerated at the prison.

Noble and Bush face charges of conspiracy, distributing and possessing child porn on federal property.

Good faces counts of possessing child pornography on federal property and accessing with intent to view.
