WASHINGTON – A judge sentenced a Marshfield, Wisconsin man Thursday to 50 years in prison for making child pornography involving an infant and toddler during the summer of 2017, according to officials.
Mark E. Bartz, 48, was sentenced by U.S. District Judge William M. Conley. Bartz pleaded guilty on July 3, to two counts of producing child pornography.
