Laura Bates already was charged in Calumet County, and Friday prosecutors in Outagamie County charged her with two counts of sexual assault by a staff member. An initial appearance is scheduled for March 18.
Officials allege 44-year-old Bates had a sexual relationship with a 17-year-old boy, who is a special education student. Bates was a paraprofessional in his classroom.
She has a March 11 preliminary hearing on the four counts in Calumet County.
