A Clark County man was sentenced Wednesday to 80 years in prison for recording his rape of a girl under 10 and an 11-month-old boy. 36-year-old Mark Anthony Davis pleaded guilty in May to two counts of production of child pornography and one count of possession of child pornography. Davis was sentenced to 30 years for each production of child pornography charge and 20 years for the possession charge, which run consecutively. That was the maximum possible prison sentence. Davis also admitted to possessing other videos of child pornography, including the rape and torture of children. This case was investigated by the Clark County Sheriff’s Department, the State Highway Patrol, the Kirksville Police Department/Kirksville Regional Computer Crimes Unit, the Henry County, Iowa, Sheriff’s Office, the FBI and an investigator with the U.S. Attorney’s office.
