A plea hearing is scheduled for a Marinette County man facing sexual assault charges. 21-year-old William Decker of Wausaukee was in court for a status conference Thursday. He’s been charged with three felony counts of sexual assault of a child, child enticement, and using a computer to facilitate a child sex crime after prosecutors say he had inappropriate contact with a 13-year-old girl he had begun talking with on Facebook last November. Decker is due back in court for his plea hearing March 12th.
