Two men have been sentenced, and another has admitted guilt in three separate child pornography cases. Seventy-one-year-old Charles Louis Linville of Davenport was sentenced to three years in federal prison for possession of child pornography.

He was charged after an investigation into a file-sharing site. Police seized his computer and found thousands of images of child porn stored on it. They also found Linville had multiple digital recording devices — including underwater face masks that could record video — which Linville used to record a child swimming in her bathing suit.

A Missouri man will serve 30 years in prison after pleading guilty to sexual exploitation of a child in Iowa. Court documents show 51-year-old James Jones of Maysville, Missouri admitted that in 2010 he persuaded a 12-year-old female in Fayette County to take explicit pictures of herself and send them to him.

Jones had previously been convicted of taking indecent liberties with a child in North Carolina in 1981. He was sentenced to 360 months in prison and 10 years probation. The case was part of the nationwide “Project Safe Childhood” which is designed to prevent child exploitation and abuse.

In the third case, 38-year-old Steven Risk of Independence admitted that between June of 2011 and February of 2013 he distributed child porn. He also admitted to possessing child porn. Risk is in custody awaiting sentencing. The charges against him carry a maximum sentence of 40 years and a maximum fine of $500,000.
