A Logan County man has been sentenced to 25 years in prison after pleading guilty to secretly videotaping young girls in a bathroom at his home and trading the images for other online child pornography. 32-year-old Mickell Close will also face 20 years of court supervision after he's released, and will have monitoring software on any computer he owns or uses. Federal authorities arrested Close in November as part of a national child pornography sweep that rescued dozens of victims of child exploitation. Investigators say numerous images of young girls in sexually explicit activity or bondage were found on Close's computers.
