A former Paulding County school teacher has been indicted on charges of possessing child pornography.

Joseph Monroe Wilson, 43, a former teacher at New Georgia Elementary in Villa Rica, was indicted by a federal grand jury July 24 on charges that he received sexually explicit images and movies of young boys from a Canadian company, U.S. Attorney Sally Quillian Yates said in a statement Monday.

Wilson came under suspicion following an investigation by the U.S. Postal Inspection Service.

In March, authorities executed a search warrant at Wilson's home in Dallas and discovered a portrait of a naked boy in Wilson's closet and sexually explicit images of children on his home computer, Yates said.

At the time, she said, Wilson was in the process of adopting a 7-year-old boy. The adoption will not take place, Yates said.

Wilson is charged with receipt of child pornography, which carries a maximum penalty of 20 years in prison and a $250,000 fine; and possession of child pornography, which carries a maximum penalty of 10 years in prison and $250,000 fine.

U.S. Magistrate Judge Linda Walker on Monday set bond for Wilson at $150,000 with conditions that include home detention, GPS monitoring and a requirement that Wilson stay away from children. He is currently residing in Spartanburg, S.C.
