A self-styled "home-based minister" from Summerville got a four-year federal prison sentence Monday after he pleaded guilty to possession of child pornography, authorities said.

Kevin Jerome Powers, 48, of 117 Logan Drive was sentenced by U.S. District Judge P. Michael Duffy, according to a news release from the U.S. Attorney for South Carolina. Duffy also stipulated that when Powers completes his prison term, he will be on supervised release for the rest of his life.

Powers' wife called the Dorchester County Sheriff's Office in March 2009 to report she had found pornography on his computer.

After deputies arrived, Powers consented to the search of his computer and agreed to be interviewed. He confessed to downloading thousands of images of child pornography over the past five years, the release states. A forensic examination of Powers' computer found more than 100 videos of child pornography.

Evidence presented at the hearing established that Powers had downloaded child pornography using the Limewire file-sharing program, the release states.

At the time of his arrest, Powers told deputies he was a minister. Neighbors said he built his own church in the backyard of the couple's home. Neighbors reported that Powers and his wife kept mostly to themselves but occasionally would talk with them about religious matters.
