A Kingsport man has been arrested after a grand jury indicted him on child pornography charges. 24 year old Keith Shapardon was located and arrested at his home. He became the subject of a Sullivan County Sheriff's Department investigation last May. A raid was conducted on his home, and his computer was seized. More than 100 images of child porn were recovered from his hard drive. He was also charged with tampering with evidence for allegedly destroying a thumb drive when he learned he was being investigated. (jb)
