A 29-year-old Forsyth County man was sentenced Thursday to five years in federal prison on child pornography charges.

Andrew John Googins, who authorities say used the screen name “fallenone666” on a computer file-sharing program, pleaded guilty Feb. 3 to distributing, receiving and possessing child pornography.

Googins was sentenced by U.S. District Judge Richard W. Story. His prison sentence will be followed by supervised release for the rest of his life.

Sally Quillian Yates, U.S. Attorney for the Northern District of Georgia, said in a statement that Googins “collected an enormous number — more than 120,000 — of horrible images and videos portraying the sexual abuse of young children.”

According to Yates, “Googins amassed the collection using computer software, and shared the pornography over the Internet with other offenders.”

Googins was arrested in October 2010 following an investigation by the Forsyth County Sheriff’s Office and Georgia Bureau of Investigation.

According to the U.S. Attorney’s office, an undercover FBI task force officer downloaded images and videos of child pornography from someone identified only by the screen name “fallenone666.”

The graphic images were then traced to Googins’ home in Cumming. The U.S. Attorney’s office said a subsequent search turned up a laptop computer that contained file sharing software and more than 120,000 images of child pornography.

Forsyth County Sheriff Ted Paxton hailed the work “done by our investigators.”

“Being able to identify Mr. Googins and get him removed from taking advantage and exploiting young children is something we’re very pleased with,” Paxton said in a statement.

He added that Googins and those like him continue to be a worldwide problem, which began with the advent of the Internet.

“It has turned into a very lucrative business of exploiting young children in the area of pornography and also certainly leads to predators of young children who, as we know, have the ability and sometimes carry out serious sexual assaults of young children,” he said.

“That’s why we dedicate the resources and the manpower that we have in doing our part to identify these individuals and remove them from the community.”
