Two western Wisconsin men made court appearances in La Crosse County Circuit Court Thursday to face child sex charges. Forty-two-year-old Robert Mattingley of La Crosse was charged with use of a computer to facilitate a sex crime and attempted sexual assault of a child. Fifty-five-year-old Michael Connelly of Onalaska was arrested on the same charges, but there is additional paperwork to be completed before a criminal complaint is filed in his name. Mattingley was arrested when he set up a meeting with who he thought was a 14-year-old girl. He was met by Holmen police. Details of Connelly’s arrest weren’t released.
