A northeast Iowa teacher has been accused of having sex with a student.
Court records say 29-year-old Tiffany Ranweiler-Oblander is charged with sexual exploitation by a counselor, therapist or school employee. On Friday her attorneys entered for her a written plea of not guilty. A trial hasn't been sentenced.
The Howard County Sheriff's Office says investigators have determined that Ranweiler-Oblander had sexual contact with the boy on four days at the boy's home.
She works for the Howard-Winneshiek district.
