SIOUX FALLS, S.D. (AP) – The superintendent of the Miller School District has resigned his post and a seat on the state high school activities board less than a month after a paternity suit was filed by a former student. Circuit Judge Jon Erickson ordered Michael Ruth to take a paternity test. Jacqueline Maria St. John filed a lawsuit in Hand County on Feb. 26. St. John said in an affidavit that she met Ruth when he was her superintendent at Miller High School, and the two began a sexual relationship after she graduated. She said Ruth denied being the father and refused testing. St. John said she has medical expenses from the pregnancy and wants the court to determine past and future child support. A message left for Ruth’s attorney was not immediately returned.
