A woman in the Philippines performed sexual acts on her 6- and 8-year-old daughters and recorded them to be streamed over the Internet to child pornography viewers around the world.

The man behind the videos, authorities say: a 47-year-old Conyers man who directed, produced and distributed them.

Jeff Clouse was sentenced Tuesday to 20 years in prison followed by 50 years of supervised release. He had pleaded guilty in June 2014.

“Clouse created a series of vile videos depicting a mother sexually abusing her own young children,” said acting U.S. attorney John Horn. “He further exploited these children by trading the videos for more child pornography. This is simply one of those cases that defies any explanation ….”

In January 2012, Department of Homeland Security agents in Phoenix investigated a person using a Russian file sharing website to trade child porn, Horn said. They found that the person was exchanging child porn with an email address in Atlanta associated with Clouse.

Agents went to Clouse’s home in February 2013 and Clouse admitted he had thousands of images of child porn and actively traded it on the Internet, authorities said.

Agents found videos apparently made with a web camera that showed Clouse directing the woman as she abused her daughters on a live video link. Chat logs found on Clouse’s computer indicated the woman lived in the Philippines and the small children in the videos are her daughters, authorities said.

Clouse admitted he met the woman online in a chat room and that she created the videos at his direction using a web camera on her computer. Clouse saved the videos on his computer so that he could view and trade the images at a later time.

Clouse then distributed the videos to other individuals who were seeking child porn, using them to obtain more child porn from other pedophiles.

“This case exemplifies the international nature of the modern child pornography trade,” said special agent in charge Nick Annan, head of ICE Homeland Security Investigations in Atlanta. “As we learn more and more in these investigations, the fight against child pornography is clearly global in nature …”
