An assistant librarian at Cheyenne High School appeared in court this morning on charges of performing a lewd act on a 17-year-old boy. The police report indicates 47-year-old Donna Washburne was arrested Sunday. The alleged incident occurred in the back seat of Washburne's car, which was parked near some portable trailers on the school's campus. Washburne says she thought the boy was 18 years-old.
